<p>Today's <strong>Image of the Day</strong> from the European Space Agency features a dazzling view of the globular cluster NGC 1786, which was captured by the Hubble Space Telescope.&nbsp;</p>



<p>Unlike open <a href="https://www.earth.com/news/trio-of-star-clusters-may-be-the-same-system-at-different-ages/">clusters</a>, which are younger and more loosely arranged, globular clusters are tightly concentrated and typically located in a galaxy’s halo.</p>



<p>The globular cluster NGC 1786 is located in the Large Magellanic Cloud (LMC) - a satellite galaxy of the Milky Way about 160,000 light-years from Earth.&nbsp;</p>



<p>“NGC 1786 itself is in the constellation Dorado. It was discovered in the year 1835 by John Herschel,” noted <a href="https://www.esa.int/ESA_Multimedia/Images">ESA</a>.</p>



<h2 class="wp-block-heading" id="h-observing-globular-clusters-nbsp">Observing globular clusters&nbsp;</h2>



<p>Globular clusters are densely packed, spherical groups of stars that orbit the cores of galaxies like satellites.&nbsp;</p>



<p>Each cluster can contain tens of thousands to millions of stars, all bound tightly together by gravity. These stars are generally very old - often over 10 billion years - making globular clusters some of the oldest known structures in the universe.</p>



<p>The image of NGC 1786 is part of a broader observing program aimed at comparing old globular clusters in nearby dwarf galaxies with those found in the <a href="https://www.earth.com/news/milky-way-galaxy-may-be-inside-a-giant-void-in-the-universe-explains-hubble-tension/">Milky Way</a>.&nbsp;</p>



<p>“Our galaxy contains over 150 of these old, spherical collections of tightly-bound stars, which have been studied in depth - especially with Hubble Space Telescope images like this one, which show them in previously-unattainable detail,” said ESA.</p>



<p>“Being very stable and long-lived, they act as galactic time capsules, preserving stars from the earliest stages of a galaxy’s formation.”</p>



<h2 class="wp-block-heading" id="h-stars-in-globular-clusters">Stars in globular clusters</h2>



<p>For many years, astronomers believed that the stars in globular clusters all formed at roughly the same time. However, studies of Milky Way clusters have revealed multiple <a href="https://www.earth.com/news/zhulong-spiral-galaxy-like-milky-way-discovered-at-edge-of-universe-should-not-exist/">stellar populations</a> of different ages.&nbsp;</p>



<p>To better understand how globular clusters form - and how they can be used to trace galactic evolution - researchers are now investigating whether clusters like NGC 1786 in external galaxies also show signs of multiple stellar generations.&nbsp;</p>



<p>This research sheds light on the origins and development of the Large Magellanic Cloud. It also helps scientists study the formation history of the Milky Way itself.</p>



<h2 class="wp-block-heading" id="h-large-magellanic-cloud-nbsp">Large Magellanic Cloud&nbsp;</h2>



<p>The Large Magellanic Cloud (LMC) is one of the most prominent and intriguing galaxies in our cosmic neighborhood. It is the largest satellite galaxy of the Milky Way and is visible to the naked eye from the Southern Hemisphere.&nbsp;</p>



<p>A <a href="https://www.earth.com/news/dozens-of-ghost-galaxies-may-be-orbiting-the-milky-way/">satellite galaxy</a> is a smaller galaxy that orbits a larger one due to gravitational attraction. Just as the Moon orbits the Earth, satellite galaxies are bound to larger galaxies and can slowly orbit them over billions of years. </p>



<p>These satellites can range in size from relatively massive dwarf galaxies to tiny, faint collections of stars.</p>



<p>Though classified as a dwarf galaxy, the Large Magellanic Cloud spans roughly 14,000 light-years across and contains billions of stars, nebulae, and star clusters.&nbsp;</p>



<p>One of its most famous features is the Tarantula Nebula - the most active star-forming region in the entire Local Group of galaxies. This stellar nursery is so intense that it's forming some of the most massive stars ever observed.</p>



<h2 class="wp-block-heading" id="h-dynamic-interaction-with-the-milky-way-nbsp">Dynamic interaction with the Milky Way&nbsp;</h2>



<p>The Large Magellanic Cloud is also of great interest to astronomers because of its dynamic relationship with the <a href="https://www.earth.com/news/our-solar-systems-journey-through-the-milky-way-may-have-altered-earths-climate/">Milky Way</a>. It’s not just a passive companion - it’s interacting gravitationally with both the Milky Way and the Small Magellanic Cloud, another nearby dwarf galaxy.&nbsp;</p>



<p>These interactions have created long streams of gas, such as the Magellanic Stream, that arc across the sky. In fact, recent studies suggest the Large Magellanic Cloud may be on its first infall into the Milky Way’s halo, rather than orbiting it for billions of years as once thought.&nbsp;</p>



<p>This motion could have significant effects on the structure of our galaxy, possibly even perturbing the Milky Way’s dark matter halo.</p>



<h2 class="wp-block-heading" id="h-significance-of-the-research">Significance of the research </h2>



<p>The detailed observations of NGC 1786 not only showcase the stunning capabilities of the <a href="https://science.nasa.gov/mission/hubble/">Hubble Space Telescope</a> but also deepen our understanding of how galaxies like the Milky Way and the LMC evolve over time.&nbsp;</p>



<p>By examining ancient globular clusters in both the Milky Way and its neighboring galaxies, astronomers are uncovering vital clues about star formation and the processes that shaped our universe.</p>

Glittering time capsule: Hubble peers into a galaxy's past

Today's Image of the Day from the European Space Agency...

<p>Today’s Image of the Day from the European Space Agency features an incredible phenomenon that was captured on the far outskirts of the Milky Way.</p>



<p>A young, massive star has announced its arrival with a dramatic display. It has fired off twin <a href="https://www.earth.com/news/webb-captures-a-young-stars-jet-colliding-with-space-dust/">jets</a> of gas so powerful they stretch across eight light-years - about twice the distance from our Sun to the Alpha Centauri system.&nbsp;</p>



<p>These streams are confined to narrow beams by the star’s magnetic fields and launched along its spin axis.&nbsp;</p>



<h2 class="wp-block-heading" id="h-the-jets-of-a-young-star">The jets of a young star</h2>



<p>The James Webb Space Telescope captured the event in exquisite infrared detail, showing the jets carving their way through interstellar gas and dust.</p>



<p>The stellar outburst belongs to a rare class of cosmic displays known as Herbig-Haro objects. They form when material falling onto a <a href="https://www.earth.com/news/baby-star-wsb-52-fires-an-explosive-jet-that-crashed-back-into-its-own-planetary-disk/">newborn star</a> is shot back out into space at incredible speeds.&nbsp;</p>



<p>The star at the heart of this spectacle lies in a cluster about 15,000 light-years away. The star has a mass that is already ten times greater than the Sun’s.&nbsp;</p>



<p>The outflow is hurtling through space at hundreds of thousands of miles per hour, leaving behind a trail that astronomers can now study as a record of the star’s growth.</p>



<h2 class="wp-block-heading" id="h-an-unexpected-discovery">An unexpected discovery</h2>



<p>The discovery took astronomers by surprise, including Yu Cheng of the National Astronomical Observatory of Japan (<a href="https://www.nao.ac.jp/" target="_blank" rel="noreferrer noopener">NAOJ</a>). </p>



<p>“We didn’t really know there was a massive star with this kind of super-jet out there before the observation. Such a spectacular outflow of molecular hydrogen from a massive star is rare in other regions of our galaxy,” said Cheng.&nbsp;</p>



<p>More than 300 Herbig-Haro objects are known, but most of them come from stars much smaller than this one. Webb’s sharp images reveal not just the scale but also the delicate structure of this jet, including knots, shocks, and filaments where the stream slams into surrounding material.</p>



<p>“I was really surprised at the order, symmetry, and size of the jet when we first looked at it,” said Jonathan Tan of the <a href="https://www.virginia.edu/" target="_blank" rel="noreferrer noopener">University of Virginia</a>.</p>



<p>The perfect alignment of the opposite streams suggests the process fueling this star’s growth has been steady for more than 100,000 years.</p>



<h2 class="wp-block-heading" id="h-mystery-of-massive-star-formation-nbsp">Mystery of massive star formation&nbsp;</h2>



<p>The new <a href="https://www.esa.int/ESA_Multimedia/Images/2025/09/Immense_stellar_jet_in_Milky_Way_outskirts#msdynmkt_trackingcontext=0ad1e29a-3bb6-4b03-99c0-1f5c2ba20000" target="_blank" rel="noreferrer noopener">observation</a> has reopened one of the longest-running debates in astronomy: how do massive stars form? For decades, scientists have been split between two main ideas. </p>



<p>One theory suggests that stars this large form through a steady process called core accretion, where gas builds up in a stable disk and launches outflows in predictable directions.&nbsp;</p>



<p>The other theory, known as competitive accretion, involves a chaotic tug-of-war in which streams of gas fall in from all sides, twisting the orientation of the jets.</p>



<p>The Webb data now tilt the balance toward the first explanation. The opposing jets are nearly 180 degrees apart, showing that the central disk has remained steady throughout the star’s lifetime.&nbsp;</p>



<p>“What we’ve seen here, because we’ve got the whole history - a tapestry of the story - is that the opposite sides of the jets are nearly 180 degrees apart from each other. That tells us that this central disc is held steady and validates a prediction of the core accretion theory,” said Tan.</p>



<h2 class="wp-block-heading" id="h-conditions-of-the-early-universe-nbsp">Conditions of the early universe&nbsp;</h2>



<p>The star’s home lies in a cluster called Sharpless 2-284, a relatively pristine region on the galaxy’s periphery. Because it is far from the Milky Way’s busy center, its <a href="https://www.earth.com/news/how-the-universes-first-molecule-helped-ignite-the-stars/">stars formed</a> in an environment low in heavy elements.&nbsp;</p>



<p>Astronomers call this property metallicity, and it mirrors the conditions of the early universe, before multiple generations of <a href="https://www.earth.com/news/wild-discovery-twin-stars-with-parallel-disks-and-jets/">stars</a> had enriched space with the products of nuclear fusion.</p>



<p>“Webb’s exquisite data have also shown us that relatively more stars seem to form at lower masses in Sh2-284 than in closer, more metal-rich clusters. This cluster is an excellent region to help us understand star formation throughout the Universe,” said Morten Andersen of the <a href="https://www.eso.org/public/" target="_blank" rel="noreferrer noopener">European Southern Observatory</a>.</p>

Young star lights up the Milky Way with colossal jets

Today’s Image of the Day from the European Space Agency...

<p>Today’s Image of the Day from NASA Earth Observatory features a dramatic view of dust sweeping across the Tarim Basin in western China - one of the dustiest places on Earth. </p>



<p>Spring and summer usually grab the headlines for dust activity, but that doesn’t mean the skies clear in the other months. <a href="https://earthobservatory.nasa.gov/images/154772/dust-in-the-eye-of-the-tarim-basin" target="_blank" rel="noreferrer noopener">Satellite data</a> and ground observations show that autumn brings its share of haze too. </p>



<p>Known for its unusual eye-like shape, the Tarim Basin is surrounded by mountains that often trap dust inside. This natural barrier keeps the fine particles from traveling far beyond the <a href="https://www.earth.com/news/dust-from-africa-sparked-a-massive-phytoplankton-bloom/">desert</a> floor, creating persistent hazy conditions.</p>



<h2 class="wp-block-heading" id="h-a-landscape-shaped-by-tectonic-power">A landscape shaped by tectonic power</h2>



<p>Look north and the “eyebrow” of the Tarim reveals striking ridges running east to west. These aren’t ordinary hills but part of the Kuqa fold-and-thrust belt.&nbsp;</p>



<p>Millions of years of tectonic forces pushed the Tarim Basin against its mountainous neighbors to the north, squeezing rock layers until they buckled and folded. The result is a series of wave-like formations called anticlines and synclines.</p>



<p>Over time, erosion has carved into these ridges, peeling back layers of red and green sandstones and pale limestones. From above, these colorful stripes stand out sharply against the muted tones of the desert around them.&nbsp;</p>



<p><a href="https://earthobservatory.nasa.gov/images/154126/a-curtain-of-dust-over-the-tarim-basin" target="_blank" rel="noreferrer noopener">Landsat images</a> have captured the intricate detail of this fractured geology, offering a glimpse into the dynamic forces that continue to shape the region.</p>



<h2 class="wp-block-heading" id="h-counting-the-dusty-days">Counting the dusty days</h2>



<p>Scientists studied more than 30 years of satellite records and found that the Tarim Basin averaged 60 dusty days a year. The month of September typically saw seven.&nbsp;</p>



<p>About 85 percent of those days fell into a category called “floating dust.” On such days, winds were light but visibility dropped below six miles as particles lingered in the air.</p>



<p>The rest of the time, conditions were harsher. On “blowing dust” days, moderate winds reduced visibility to less than three miles. The most extreme <a href="https://www.earth.com/news/dust-storms-are-a-surprising-source-of-deadly-air-pollution/">dust storms</a> cut visibility to under half a mile, carried by powerful gusts that scoured the landscape.</p>



<h2 class="wp-block-heading" id="h-dust-size-tells-a-seasonal-story">Dust size tells a seasonal story</h2>



<p>Not all dust is the same. By comparing seasons, researchers found that larger particles show up most often in spring, fall, and winter.&nbsp;</p>



<p>NASA’s Terra satellite, using its Multi-angle Imaging SpectroRadiometer, provided the detail. These coarse grains likely lift when strong horizontal winds sweep across the desert.</p>



<p>Summer is different. Rising heat drives localized convection, creating dust whirls - sometimes called dust devils - that pull smaller, finer grains into the air.&nbsp;</p>



<p>These swirling columns may look less threatening than a full storm, but they can still loft material high into the atmosphere.&nbsp;</p>



<p>The seasonal contrast shows how different forces, from heat to wind, work together to keep the basin’s air loaded with dust.</p>



<h2 class="wp-block-heading" id="h-dust-from-the-tarim-basin-nbsp">Dust from the Tarim Basin&nbsp;</h2>



<p>Dust from the Tarim Basin doesn’t just linger over western China. Depending on weather patterns, it can drift across Asia, impacting air quality in major cities. In extreme cases, it may even cross <a href="https://www.earth.com/news/atmospheric-dust-plays-surprisingly-crucial-role-in-stabilizing-ocean-ecosystems/">oceans</a>.&nbsp;</p>



<p>These particles influence more than visibility. They affect climate by reflecting sunlight or trapping heat, and they alter ecosystems when they settle far from their source.</p>



<p>Understanding when and how dust moves is key for both health and climate research. The Tarim Basin offers a natural laboratory where scientists can track these processes in detail, thanks to decades of satellite coverage and on-the-ground measurements.</p>



<h2 class="wp-block-heading" id="h-a-reminder-of-nature-s-reach">A reminder of nature’s reach</h2>



<p>The desert may seem remote, but its restless skies have a global <a href="https://www.earth.com/news/dust-is-an-understudied-contributor-to-climate-change/">footprint</a>. What satellites recorded in early September was just one episode in a cycle that repeats year after year.&nbsp;</p>



<p>Tectonic history, seasonal winds, and rising heat all converge in this basin to keep the air in motion.&nbsp;</p>



<p>For scientists, the Tarim continues to show how landscapes that appear still and silent are, in fact, alive with change.</p>



<p>The image was captured on September 1, 2025 by the NOAA-20 satellite.&nbsp;</p>

China’s Tarim Basin: A desert that never sleeps

Today’s Image of the Day from NASA Earth Observatory features...

<p>Today’s Image of the Day from NASA Earth Observatory features Hurricane Kiko, spinning west across the Pacific Ocean toward the Hawaiian Islands.</p>



<p>Hurricane Kiko began as a tropical depression on August 31 in the eastern Pacific. Within days, it rapidly gained strength and climbed into major <a href="https://www.earth.com/news/climate-change-has-amplified-hurricane-strength/">hurricane</a> status. By early September, it was heading west with Hawaii in its path - raising concerns about what the islands might face.</p>



<p>The storm’s approach forced Hawaii to prepare for high surf, rip currents, and shifting forecasts. While the cyclone weakened as it neared land, the ocean did not quiet down, and warnings were issued for dangerous conditions along east-facing shores.</p>



<h2 class="wp-block-heading" id="h-calm-beginnings-to-furious-winds">Calm beginnings to furious winds</h2>



<p>Kiko’s early days followed the typical pattern of many Pacific hurricanes. Warm waters and unstable atmospheric conditions fueled its rise from depression to named storm, and then to hurricane.&nbsp;</p>



<p>At its peak, Kiko wavered between Category 3 and Category 4 strength. On September 4, its sustained winds reached 145 miles per hour, enough to rank it among the most powerful storms of the season.</p>



<h2 class="wp-block-heading" id="h-observing-kiko-from-space">Observing Kiko from space</h2>



<p>On September 7 at about 1:30 p.m. Hawaii Standard Time, satellites offered a clear view of the storm.</p>



<p>Today’s featured <a href="https://earthobservatory.nasa.gov/images/154769/hurricane-kiko-nears-hawaii" target="_blank" rel="noreferrer noopener">image</a> reveals a vast spiral with a defined center. At this time, it was a Category 2 system with winds of 110 miles per hour. </p>



<p>The photo was captured by instruments aboard the Suomi NPP satellite when Hurricane Kiko was about 600 miles east of Hilo. </p>



<p>These satellite snapshots are crucial for monitoring storm size, cloud structure, and <a href="https://www.earth.com/news/what-causes-the-rapid-intensification-of-hurricanes/">intensity</a>. They help forecasters understand how the cyclone is evolving as it moves across the ocean.</p>



<h2 class="wp-block-heading" id="h-why-the-storm-weakened">Why the storm weakened</h2>



<p>Hurricanes thrive on warm water and favorable atmospheric conditions. But Kiko encountered hurdles that sapped its energy.&nbsp;</p>



<p>The National Hurricane Center noted that cooler water played a role in its decline. In addition, moderate vertical wind shear - the shifting of wind direction and speed with altitude - disrupted the storm’s internal structure. A dry surrounding environment further limited the fuel supply.</p>



<p>All of these factors caused Kiko to lose some of its punch as it pushed closer to Hawaii. Even so, the system remained large enough to stir up trouble in the seas.</p>



<h2 class="wp-block-heading" id="h-hurricane-kiko-forecasts">Hurricane Kiko forecasts</h2>



<p>As of September 8, meteorologists expected Kiko to veer northwest, weaken to a tropical storm, and pass north of the Hawaiian Islands on September 9 and 10.&nbsp;</p>



<p>That track suggested the islands might avoid damaging winds and widespread heavy rainfall. But not every hazard depends on direct landfall.</p>



<p>The National Hurricane Center warned that east-facing coastal areas could see dangerous surf and rip currents. These hazards often linger long after the storm’s eye has passed, and they pose risks to swimmers, boaters, and anyone near the shoreline.</p>



<h2 class="wp-block-heading" id="h-hawaii-s-storm-history">Hawaii’s storm history</h2>



<p>Hawaii sits in the middle of the Pacific, far from continental landmasses but not immune to tropical <a href="https://www.earth.com/news/even-weak-storms-are-deadly-for-infants-in-developing-nations/">cyclones</a>. While direct hits are rare, the islands have experienced damaging storms in the past.&nbsp;</p>



<p>Hurricane Iniki in 1992 was the strongest to strike Hawaii in recorded history, causing widespread destruction on Kauai. More recently, storms like Lane in 2018 and Douglas in 2020 skirted the islands but still produced heavy rains and flooding.</p>



<p>Kiko fits into this long-running narrative: powerful systems often threaten Hawaii, and even near misses bring serious impacts. For residents and visitors alike, the warnings serve as reminders of the Pacific’s power.</p>



<h2 class="wp-block-heading" id="h-preparing-for-the-next-storm">Preparing for the next storm</h2>



<p>Forecasting has improved in recent decades thanks to satellite technology, advanced computer models, and constant monitoring by meteorologists.&nbsp;</p>



<p>These tools give island communities more time to prepare for changing conditions. Emergency managers urge residents to take <a href="https://www.earth.com/news/why-hurricane-warnings-fail-to-convey-the-real-danger/">warnings</a> seriously, even if the storm’s center never crosses land.</p>



<p>High surf alone can be life-threatening, and rip currents claim lives every year. For island states like Hawaii, where the ocean defines daily life, respecting these warnings is vital.</p>

Hurricane Kiko spins toward Hawaii 

<p>Today's <strong>Image of the Day</strong> from the European Space Agency showcases the striking beauty of the planetary nebula NGC 2899, which resembles a moth in flight. The photo was captured by the Hubble Space Telescope.</p>



<p>“The planetary nebula NGC 2899 is shaped like a single macaroni noodle, with its edges pointed up, but its edge-on central torus is semi-transparent in the middle,” noted <a href="https://www.esa.int/ESA_Multimedia/Images" target="_blank" rel="noreferrer noopener">ESA</a>.</p>



<p>“The top and bottom edges are thick and orange. The center is semi-transparent blue and green. The wider central region looks roughly like a moth, also filled with semi-transparent blue and green.”</p>



<h2 class="wp-block-heading" id="h-defining-features-of-the-planetary-nebula">Defining features of the planetary nebula</h2>



<p>According to ESA, the nebula features a bipolar, cylindrical outflow of gas extending diagonally. The gas is driven by intense radiation and stellar winds from a central <a href="https://www.earth.com/news/white-dwarf-planets-are-more-habitable-than-we-thought/" target="_blank" rel="noreferrer noopener">white dwarf</a> with a scorching temperature of nearly 22,000 degrees Celsius. </p>



<p>“In fact, there may be two companion stars that are interacting and sculpting the nebula, which is pinched in the middle by a fragmented ring or torus - looking like a half-eaten donut,” said ESA.</p>



<p>Streams of gaseous “pillars” extend outward, all pointing back toward the central source of energy. The vibrant colors in the image come from glowing hydrogen and oxygen gases.&nbsp;</p>



<h2 class="wp-block-heading" id="h-discovery-and-significance-of-ngc-2899">Discovery and significance of NGC 2899</h2>



<p>NGC 2899 was discovered by British astronomer John Herschel on March 2, 1835, during his survey of the southern skies from the Cape of Good Hope in South Africa. </p>



<p>Herschel cataloged many deep-sky objects in the southern hemisphere, contributing significantly to the New General Catalogue (NGC) compiled later by John Louis Emil Dreyer.</p>



<p>NGC 2899 is located approximately 4,500 light-years from Earth in the southern constellation Vela, which is part of the larger Vela-Puppis-Carina region of the Milky Way known for its rich <a href="https://www.earth.com/news/fluffy-molecular-clouds-may-change-our-understanding-of-star-formation/" target="_blank" rel="noreferrer noopener">star-forming activity</a> and remnants of past stellar explosions.&nbsp;</p>



<p>Vela, whose name means "sails" in Latin, represents the sails of the ancient Greek mythological ship Argo Navis. This region of the sky is particularly abundant in nebulae, star clusters, and other deep-sky objects, making it a focal point for astronomical observations.&nbsp;</p>



<p>The nebula’s distance places it well within our galaxy, offering astronomers a valuable glimpse into the later stages of stellar evolution and the processes that sculpt and illuminate planetary nebulae.</p>



<h2 class="wp-block-heading" id="h-what-is-a-planetary-nebula">What is a planetary nebula?</h2>



<p>Nebulae are vast clouds of gas and dust in space, often serving as the birthplaces or remnants of stars.&nbsp;</p>



<p>They come in various types, including emission nebulae that glow due to ionized gases energized by nearby stars, reflection nebulae that shine by scattering starlight, and dark nebulae that obscure light from background <a href="https://www.earth.com/news/runaway-star-may-be-dragging-a-planet-along-with-it/" target="_blank" rel="noreferrer noopener">stars</a>.&nbsp;</p>



<p>Planetary nebulae form when dying stars shed their outer layers, creating colorful, often symmetrical shapes. Nebulae can span light-years across and are key to understanding the life cycles of stars and the structure of galaxies.</p>



<h2 class="wp-block-heading" id="h-the-fate-of-dying-stars">The fate of dying stars</h2>



<p>Not all dying stars become planetary nebulae. In fact, stars much more massive than the Sun follow a very different and far more violent path.&nbsp;</p>



<p>These massive stars end their lives in dramatic supernova explosions, releasing tremendous energy and scattering heavy elements into space, which enriches the interstellar medium.&nbsp;</p>



<p>What remains after the explosion depends on the star’s mass. The collapsed core can form a neutron star - an incredibly dense object composed mostly of neutrons. Or, if the star was even more massive, it may create a <a href="https://www.earth.com/news/astronomers-confirm-lone-black-hole-wandering-through-our-galaxy/" target="_blank" rel="noreferrer noopener">black hole</a>, where gravity is so intense that not even light can escape.</p>



<h2 class="wp-block-heading" id="h-examples-of-winged-nebulae-nbsp">Examples of “winged” nebulae&nbsp;</h2>



<p>Several well-known nebulae are noted for their "winged" or symmetrical, wing-like appearances, often earning them evocative nicknames.&nbsp;</p>



<p>One of the most famous is the Butterfly Nebula, located in the constellation Scorpius. This planetary <a href="https://www.earth.com/news/dragons-egg-nebula-is-a-truly-stunning-sight-to-behold/" target="_blank" rel="noreferrer noopener">nebula</a> displays two expansive lobes that resemble butterfly wings, shaped by fast stellar winds from a dying star.</p>



<p>The Omega Nebula (also known as the Swan Nebula) in the constellation Sagittarius is a bright star-forming region that has been said to resemble a swan in flight. It has broad, glowing "wings" formed by clouds of ionized hydrogen gas.&nbsp;</p>



<p>Similarly, the Eagle Nebula has an overall shape reminiscent of a bird with outstretched wings, which inspired its name. It is located in the constellation Serpens and home to the iconic "Pillars of Creation."</p>

According to <a href="https://www.esa.int/ESA_Multimedia/Images/2025/04/Barred_Spiral_Galaxy_NGC_5335" target="_blank" rel="noreferrer noopener">ESA</a>, thousands of distant galaxies are speckled throughout the image in a variety of colors.&nbsp;</p>



<p>Hubble is revealing how <a href="https://www.earth.com/news/hidden-galaxies-discovery-would-upend-current-understanding-of-universe/">galaxies</a> form, grow, and evolve over cosmic time by capturing detailed images of galaxies at various stages of development, from the nearby universe to billions of light-years away.</p>



<p>Hubble images have shown us that galaxies collide and merge, that star formation varies across different types of galaxies, and that supermassive black holes often lie at their centers.</p>



<h2 class="wp-block-heading" id="h-studying-ngc-5335">Studying NGC 5335</h2>



<p>The galaxy NGC 5335 lies approximately 160 million light-years from Earth. It is classified as an SB(s)bc type galaxy, indicating a well-defined bar structure across its center. </p>



<p>Like many galaxies of its type, NGC 5335 features active <a href="https://www.earth.com/news/star-formation-reignited-in-the-galaxy-leo-p-after-billions-of-years/">star formation</a>, especially in its spiral arms, where interstellar gas and dust provide the raw material for new stars. </p>



<p>Observations in different wavelengths, including infrared and ultraviolet, help astronomers study the galaxy’s stellar population and the dynamics of its central bar.</p>



<h2 class="wp-block-heading" id="h-hubble-s-view-of-the-spiral-galaxy-nbsp">Hubble’s view of the spiral galaxy&nbsp;</h2>



<p>“NGC 5335 is categorized as a flocculent spiral galaxy with patchy streamers of star formation across its disk. There is a striking lack of well-defined spiral arms that are commonly found among galaxies, including our Milky Way,” noted ESA.</p>



<p>“A notable bar structure slices across the center of the galaxy. The bar channels gas inwards toward the galactic center, fueling star formation.”&nbsp;</p>



<p>“Such bars are dynamic in galaxies and may come and go over two-billion-year intervals. They appear in about 30 percent of observed galaxies, including our Milky Way.”</p>



<h2 class="wp-block-heading" id="h-galactic-bar-in-the-milky-way-nbsp">Galactic bar in the Milky Way&nbsp;</h2>



<p>The bar in the <a href="https://www.earth.com/news/astronomers-found-something-strange-at-core-of-milky-way-galaxy-webb-meerkat/">Milky Way</a> is a vast, elongated structure composed mostly of stars, stretching across the galaxy’s central region. It is a key feature of our galaxy’s architecture, spanning about 27,000 light-years and oriented at an angle relative to the galaxy’s spiral arms. </p>



<p>Astronomers believe the bar plays a crucial role in the dynamics and evolution of the Milky Way by funneling gas inward toward the galactic center. This can feed star formation and fuel the supermassive black hole at the core.&nbsp;</p>



<p>The bar is thought to have formed from instabilities in the galactic disk and continues to influence the motion of stars and the overall gravitational balance of the galaxy.&nbsp;</p>



<p>Observations in infrared and radio wavelengths, which can pierce through the dust in the galactic plane, have helped scientists map the bar’s size, shape, and orientation.</p>



<h2 class="wp-block-heading" id="h-the-constellation-virgo-nbsp">The constellation Virgo&nbsp;</h2>



<p>Virgo is one of the most prominent and well-known constellations in the night sky, both astronomically and mythologically. It is the second-largest constellation by area and lies along the zodiac, making it one of the twelve constellations through which the <a href="https://www.earth.com/news/team-creates-video-showing-the-sun-in-gamma-rays-over-a-14-year-period/" target="_blank" rel="noreferrer noopener">Sun</a> appears to move during the year.&nbsp;</p>



<p>Virgo is most visible in the evening sky in the Northern Hemisphere during spring, particularly in April and May. Its name means “virgin” in Latin.</p>



<p>Virgo is traditionally associated with various fertility and agriculture goddesses across different cultures, including the Greek goddess Demeter and her daughter Persephone, as well as the Roman goddess Ceres.&nbsp;</p>



<p>In some myths, Virgo represents Astraea, the virgin goddess of justice who fled to the heavens during the corruption of mankind.</p>



<h2 class="wp-block-heading" id="h-astronomical-significance-of-virgo">Astronomical significance of Virgo</h2>



<p>Astronomically, Virgo is situated between Leo to the west and Libra to the east. One of its most notable stars is Spica, the brightest star in Virgo and one of the brightest in the night sky.&nbsp;</p>



<p>Spica is a blue-white giant, located approximately 250 light-years from <a href="https://www.earth.com/news/was-early-earth-a-purple-planet-scientists-say-its-possible/" target="_blank" rel="noreferrer noopener">Earth</a>. It has been important for navigation and agriculture for centuries, marking planting and harvest times in ancient calendars.</p>



<p>Virgo is also of great interest to astronomers because it hosts the Virgo Cluster, a massive cluster of galaxies about 65 million light-years away.&nbsp;</p>



<p>This cluster contains more than 1,000 galaxies, and it's part of the larger Virgo Supercluster, which also includes our own Local Group of galaxies. This makes Virgo a key area for studying large-scale structures in the universe.</p>

<p>Firefly Aerospace’s Blue Ghost Mission 1 made a landing near Mons Latreille in Mare Crisium on the Moon’s near side, and teams expect about one lunar day of surface operations.</p>



<p>“This incredible achievement demonstrates how NASA and American companies are leading the way in space exploration for the benefit of all,” said NASA's acting Administrator Janet Petro.</p>



<p>This marks the second commercial soft landing on the Moon,after Intuitive Machines’ <a href="https://www.nasa.gov/image-article/odysseus-lands-on-the-moon/" target="_blank" rel="noreferrer noopener">Odysseus</a> reached the surface in 2024. The latest mission carries instruments that support NASA’s Artemis plans.</p>



<p>Nicky Fox, NASA's associate administrator for science, emphasized the mission’s value to long-term exploration, and the growing role of private partners.</p>

<p>NASA’s Commercial Lunar Payload Services (<a href="https://www.nasa.gov/commercial-lunar-payload-services/" target="_blank" rel="noreferrer noopener">CLPS</a>) model buys deliveries instead of owning every spacecraft. This speeds up testing and lowers cost. </p>



<p>The agency uses competitive task orders and indefinite delivery, indefinite quantity contracts with a combined ceiling of $2.6 billion through November 2028.</p>



<p>That approach spreads risk across multiple flights, accepts that some attempts will stumble, and pushes companies to iterate fast. It also gets critical hardware onto the Moon sooner so designers can fix what breaks and scale what works.</p>



<p>For students and young engineers, this creates a clear pipeline from classroom ideas to working hardware on another world. It is a practical way to build a sustainable presence instead of one-off triumphs.</p>



<h2 class="wp-block-heading" id="h-what-blue-ghost-is-carrying">What Blue Ghost is carrying</h2>



<p>Blue Ghost delivered ten NASA <a href="https://www.nasa.gov/missions/artemis/clps/ten-nasa-science-tech-instruments-flying-to-moon-on-firefly-lander/" target="_blank" rel="noreferrer noopener">payloads</a> aimed at navigation, heat flow, dust, drilling, and plume imaging. </p>



<p>They include a subsurface drill that can reach down about 10 feet (3 meters), a sampler for lunar soil, a landing plume camera suite, a radiation tolerant computer, a magnetotelluric sounder, and a Global Navigation Satellite System (<a href="https://www.gps.gov/systems/gnss/" target="_blank" rel="noreferrer noopener">GNSS</a>) receiver.</p>



<p>The Moon’s surface is covered with <a href="https://www.nasa.gov/wp-content/uploads/2019/04/05_1_snoble_thelunarregolith.pdf" target="_blank" rel="noreferrer noopener">regolith</a>, a mix of rock fragments and fine dust that can cling to everything and grind moving parts. Learning how it flows, heats, and sticks will shape future rover wheels, seals, and spacesuits.</p>



<p>A magnetotelluric sounder listens to natural electromagnetic fields to infer the electrical properties beneath the ground. </p>



<p>Those data help scientists estimate composition and temperature at depth without explosives or seismometers.</p>



<p>Electronics also face harsh radiation, especially when missions cross the <a href="https://science.nasa.gov/biological-physical/stories/van-allen-belts/" target="_blank" rel="noreferrer noopener">Van Allen belts</a> on the way out and back. Running fault-tolerant computers on the surface helps engineers design systems that can survive months instead of hours.</p>

<p>After lift-off from Florida in mid-January, mission control guided the craft through cruise, approach, and a powered descent to Mare Crisium. </p>



<p>The lander’s legs settled upright and stable, which simplifies surface operations and protects instruments.</p>



<p>Landing near an ancient <a href="https://www.earth.com/news/volcanic-eruption-on-jupiters-moon-io-covers-area-larger-than-lake-superior-juno-mission/">volcanic</a> vent gives scientists a window into thermal history and crustal chemistry. That spot also offers good lighting for cameras that watch dust and surface changes during dawn and dusk.</p>



<h2 class="wp-block-heading" id="h-blue-ghost-1-mission-parameters">Blue Ghost 1 mission parameters</h2>



<p>Teams plan to record a lunar sunset and watch how dust behaves in low angle sunlight. That twilight period has long raised questions about near surface electric fields and how they loft fine grains off the ground.</p>



<p>A classic <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2005RG000184" target="_blank" rel="noreferrer noopener">review</a> of lunar dust physics points to charged particles that can rise and fall close to the surface, especially near the terminator where lighting changes quickly. Fresh images and measurements from Blue Ghost can test those ideas at a new site.</p>



<p>The drill will probe the thermal gradient down several feet to estimate heat flow from the interior. Those numbers help refine models of crust thickness, volcanic activity in Mare Crisium, and how fast the Moon has cooled.</p>



<p>A sampler will try out a method that uses gas to collect <a href="https://www.earth.com/news/this-weekends-corn-moon-marks-farewell-to-summer/">lunar</a> soil, or <a href="https://www.earth.com/news/new-device-turns-moon-dirt-into-water-and-oxygen-for-lunar-bases/">regolith</a>. This approach could make future missions simpler and less energy-hungry because it avoids relying on heavy robotic arms with lots of moving parts.</p>



<h2 class="wp-block-heading" id="h-why-the-landing-matters-back-on-earth">Why the landing matters back on Earth</h2>



<p>Navigation is getting an upgrade. The Lunar GNSS Receiver Experiment (<a href="https://ntrs.nasa.gov/api/citations/20220002074/downloads/LuGRE_ION-ITM_2022_Draft8_Submitted_ConferenceProceedings.pdf" target="_blank" rel="noreferrer noopener">LuGRE</a>) showed that weak <a href="https://www.nasa.gov/directorates/somd/space-communications-navigation-program/nasa-successfully-acquires-gps-signals-on-moon/" target="_blank" rel="noreferrer noopener">signals</a> from GPS and Galileo can be acquired and tracked on the Moon.</p>



<p>If future landers can use GNSS for position, velocity, and time at the Moon, they will rely less on Earth-based tracking. That frees up ground networks and lets small missions navigate more independently.</p>



<p>Dust research also loops back to Earth. The same tools used to understand charged <a href="https://www.earth.com/news/nasa-plans-to-build-a-moon-base-using-3d-printing-and-robots/">lunar</a> grains inform static control in clean rooms and the design of materials that resist wear in dusty places.</p>



<p>Finally, public private work like CLPS grows a supply chain that can build faster and smarter. As providers get repeat flights, they standardize hardware and shorten timelines, which reduces the cost for science and technology riders.</p>

NASA confirms Moon landing by a private American spacecraft

Firefly Aerospace’s Blue Ghost Mission 1 made a landing near...

<p>When people talk about iridescence, they usually think of butterflies, hummingbirds, or beetles. These animals shimmer when light hits them, creating colors that shift with each angle. </p>



<p>Mammals, by contrast, appear duller and more uniform. Their coats are typically brown, black, or grey, designed for camouflage and survival.</p>



<p>But recent research from <a href="https://www.ugent.be/en" target="_blank" rel="noreferrer noopener">Ghent University</a> shows this picture is incomplete. Some mammals carry shimmering fur that rivals the beauty of <a href="https://www.earth.com/news/mammals-tried-different-ways-to-move-before-walking-upright/">birds</a> and insects. </p>



<p>The discovery challenges long-standing assumptions and opens new questions about how common these hidden colors really are.</p>



<h2 class="wp-block-heading" id="h-a-surprising-discovery">A surprising discovery</h2>



<p>The story began in a museum, not in the wild. A researcher studying <a href="https://www.earth.com/news/mammal-evolution-kicked-off-with-daring-experiments/">mammal</a> specimens noticed an odd blue glint on the fur of a tropical vlei rat. That moment set everything in motion. Until then, golden moles were the only mammals widely recognized as iridescent. </p>



<p>These small African burrowers are known for their metallic, tinsel-like hairs. But the rat’s fur suggested something more was happening. If one overlooked species shimmered, perhaps others did too.</p>



<p>The observation was more than a curiosity. It challenged a simple claim in biology: that iridescence belonged almost entirely to creatures with scales or feathers. Mammals, it seemed, were the exception.</p>



<h2 class="wp-block-heading" id="h-searching-the-past">Searching the past</h2>



<p>Instead of stopping at the rat, the researcher dug deeper. Old scientific reports contained scattered references to shiny fur in other mammals, some dating back to the late 1800s. </p>



<p>These notes were brief and often dismissed, treated as oddities rather than serious findings. For over a century, no one had followed them up. The new discovery gave reason to revisit those forgotten records.</p>



<p>By combining modern tools with these old clues, scientists could finally test whether mammals truly showed iridescence beyond golden moles. Museum collections, filled with preserved animals from around the world, provided the perfect opportunity.</p>



<h2 class="wp-block-heading" id="h-detecting-iridescence-in-fur">Detecting iridescence in fur</h2>



<p>The team examined specimens linked to historic mentions of iridescence. They also included related species to broaden the search. Using microscopes, they shone light at different angles across the hairs and measured how it reflected. </p>



<p>This simple test revealed the truth. Golden moles were not unique. Fourteen additional mammal <a href="https://www.earth.com/news/animals-species-some-live-days-others-for-centuries-maximum-lifespan-potential-mlsp/">species</a> displayed iridescent coats. Ten were rodents. </p>



<p>Another was the giant otter shrew, a semiaquatic predator unrelated to either otters or shrews despite its name. For six of these animals, this was the first time iridescence had been scientifically recorded.</p>



<p>The discovery turned a narrow claim into a broader pattern. Iridescence in mammals, once thought to be nearly absent, now appeared in multiple groups.</p>



<h2 class="wp-block-heading" id="h-how-iridescent-fur-works">How iridescent fur works</h2>



<p>Understanding why the fur glowed required a closer look. Under high-powered microscopes, the hairs showed a special design. Normal mammal hairs are rough and uneven, made up of layers that scatter light. In contrast, iridescent hairs were smooth and compressed into parallel sheets.</p>



<p>Light striking these layers bent slightly at each surface. As the layers stacked, they bent light in multiple directions, creating interference patterns. The result was a rainbow shimmer, its colors changing as the viewing angle shifted. </p>



<p>The process resembled the one behind butterfly wings or beetle shells, though mammals achieved it through fur instead of scales.</p>



<h2 class="wp-block-heading" id="h-possible-reasons-for-iridescence">Possible reasons for iridescence</h2>



<p>Why would <a href="https://www.earth.com/news/mammals-ground-dwellers-survived-the-asteroid-impact-that-killed-the-dinosaurs/">mammals</a> develop such unusual hair? The answer is still uncertain. Many iridescent species are burrowers or swimmers. For animals living underground or in water, smooth hair could reduce dirt buildup or resist moisture. In that case, the shine would be a by-product, not an adaptation in itself.</p>



<p>Yet another explanation remains on the table. In birds, iridescence often serves as a communication tool, helping attract mates or signal dominance. </p>



<p>Mammals could use it the same way. If so, the shimmer would not be an accident but an important social feature. At present, scientists cannot say for sure. Both ideas remain possible, and both need further testing.</p>



<h2 class="wp-block-heading" id="h-more-iridescent-species-found">More iridescent species found</h2>



<p>Evidence suggests the list of iridescent mammals is far from complete. In 2024, scientists described a new shrew from Indonesia with fur that appeared somewhat shiny. </p>



<p>With around 2,500 rodent species worldwide, and only a small portion studied under microscopes, the odds of finding more iridescent examples are high.</p>



<p>Each discovery adds weight to the idea that iridescence in mammals is not a rare exception. Instead, it may be a common but overlooked trait, hidden until light strikes at the right angle.</p>



<h2 class="wp-block-heading" id="h-biology-remains-full-of-surprises">Biology remains full of surprises </h2>



<p>The findings highlight the importance of close observation. For decades, scientists assumed mammal fur was plain because it usually looks that way under normal conditions. But assumptions can blind research. </p>



<p>Only when someone noticed a small flash of color did the story begin to change. Museum collections, often viewed as archives of the past, proved vital in rewriting the present understanding of mammal biology.</p>



<p>This work also shows how biology remains full of surprises. Even groups as familiar as rodents can carry traits we barely recognize. What seems ordinary may hold complexity beneath the surface.</p>



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions </h2>



<p>Future studies will likely explore how iridescence affects animal behavior. Does it influence mating or social interactions? Does it offer camouflage under certain light conditions? Or is it simply a side effect of hair built for other environments? </p>



<p>Answering these questions will take fieldwork as well as lab analysis. The possibility of discovering many more iridescent mammals is exciting. Every new case adds to our picture of how structural colors evolve. </p>



<p>The research also reshapes our understanding of what mammals can look like. Far from being drab, some may shimmer like jewels under the right conditions.</p>



<h2 class="wp-block-heading" id="h-iridescent-beauty-in-mammals">Iridescent beauty in mammals</h2>



<p>The discovery of iridescent fur in mammals changes a basic story about animal colors. It shows that beauty and complexity are not limited to insects, birds, or reptiles. </p>



<p>Mammals, too, can hide light-bending structures in their coats. These shimmering layers may serve survival, communication, or both.</p>



<p>What began with a single flash of blue on a museum specimen has opened a new chapter in biology. It proves once again that even in well-studied groups, nature still keeps secrets. Sometimes all it takes is the right angle of light to reveal them.</p>



<p>The study is published in the <em><a href="https://royalsocietypublishing.org/doi/10.1098/rsif.2025.0508" target="_blank" rel="noreferrer noopener">Journal of the Royal Society Interface</a></em>.</p>

Not just birds and beetles: Iridescence found in unexpected animals

When people talk about iridescence, they usually think of butterflies,...

<p>A new paper documents a 9,000-year-old quartz tool workshop and a fireplace at the Ravin Blanc X (RBX-1) site in eastern Senegal. The site captures a brief moment in the work of Later Stone Age (LSA) hunter-gatherers. The evidence is preserved, like a time capsule, beneath younger deposits.</p>



<p>Archaeologists, led by Charlotte Pruvost from the <a href="https://arcan.unige.ch/en" target="_blank" rel="noreferrer noopener">ARCAN Laboratory</a> of the University of Geneva, found an exceptionally intact layer with toolmaking debris, a shallow hearth, and sediments that still hold microscopic plant and wood traces. </p>



<p>The excavated area is small, about 269 square feet (25 square meters), yet rich enough to say something meaningful about people who lived at the end of the last big climate swing into the Early Holocene.</p>



<h2 class="wp-block-heading" id="h-why-the-quartz-tool-site-matters">Why the quartz tool site matters</h2>



<p>West Africa is huge, roughly 2.3 million square miles (6 million square kilometers), yet stratified prehistoric sites are scarce and often disturbed. </p>



<p>RBX-1 gives researchers a clean, well dated context from the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0047248421000063" target="_blank" rel="noreferrer noopener">Later Stone Age</a>, a period when small, efficient <a href="https://www.earth.com/news/stone-tools-flint-created-400000-years-show-technological-advancement-of-early-humans/">tools</a> and composite hunting gear became the norm.</p>



<p>“The discovery of RBX-1 enhances our understanding of the LSA in West Africa by providing a rare, well-dated stratigraphic context,” wrote Pruvost. </p>



<p>The team reports a tight cluster of activity dated to the early part of the Holocene, the warm interval that followed the Pleistocene.</p>



<h2 class="wp-block-heading" id="h-what-the-team-found">What the team found</h2>



<p>The layer includes a quartz knapping area, about 31 inches (79 centimeters) across, where nearly 1,200 of the almost 1,500 lithic artifacts were concentrated. </p>



<p>A circular hearth nearby is about 26 inches (66 centimeters) wide, set into older sediments and ringed by reddened soil and ash.</p>



<p>No finished quartz tools were left behind, which fits a classic workshop signature. People made blanks here, selected the good ones, and carried them away for use.</p>



<h2 class="wp-block-heading" id="h-how-scientists-decoded-the-layer">How scientists decoded the layer</h2>



<p>Charcoal from the hearth yielded early Holocene ages using radiocarbon dating. This method measures the decay of carbon isotopes in once living material. The dates from different parts of the hearth agree, which supports a short, single episode of <a href="https://www.earth.com/news/first-tools-ever-made-on-earth-hominins-3-million-years-ago-cradle-of-humankind/">activity</a>.</p>



<p>Specialists also used anthracology to identify the firewood as <a href="https://tropical.theferns.info/viewtropical.php?id=Detarium+senegalense" target="_blank" rel="noreferrer noopener"><em>Detarium</em></a> species, trees that are common in Sudanian savannas. </p>



<p>To cross check the environment, the team studied <a href="https://academic.oup.com/aob/article/124/2/189/5537002" target="_blank" rel="noreferrer noopener">phytoliths</a>, tiny silica bodies that plants leave in soils. Results point to an open savanna with grasses and scattered trees, wetter than the glacial period that came before.</p>



<h2 class="wp-block-heading" id="h-what-quartz-tools-reveal">What quartz tools reveal</h2>



<p>Two distinct blank types were produced with care. One set is broad, thick, and rectilinear, with straight, parallel edges. </p>



<p>The other set is elongated, narrow, and thin, often with an oblique tip suitable for mounting as standardized armatures.</p>



<p>“The strong investment in blank standardization from the extraction stage significantly reduced the need for subsequent retouching, which was rarely observed in the RBX-1 lithic assemblage,” wrote Pruvost. </p>



<p>Standardization signals skill, planning, and a desire for uniform parts that fit composite <a href="https://www.earth.com/news/early-hominins-carried-materials-miles-with-the-intent-to-make-stone-tools/">weapons</a>.</p>



<h2 class="wp-block-heading" id="h-west-africa-in-a-changing-climate">West Africa in a changing climate</h2>



<p>The workshop sits at the opening of the <a href="https://en.wikipedia.org/wiki/African_humid_period" target="_blank" rel="noreferrer noopener">African Humid Period</a>, when monsoon rains pushed north and savannas expanded. </p>



<p>Climatic <a href="https://www.nature.com/articles/s41467-017-01454-y" target="_blank" rel="noreferrer noopener">studies</a> show that these wet conditions fluctuated across northern Africa during the Holocene, reshaping water, vegetation, and human mobility.</p>



<p>Phytoliths and charcoal at RBX-1 agree with that broader picture. People were working in a grass-rich savanna with available wood and stable surfaces that protected small flakes from being washed away.</p>

<h2 class="wp-block-heading" id="h-comparisons-across-the-region">Comparisons across the region</h2>



<p>RBX-1 is not alone, and the comparisons matter. At Fatandi V in the same valley, researchers <a href="https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0243129" target="_blank" rel="noreferrer noopener">reported</a> stratified LSA layers with systematic bladelet production and microliths. </p>



<p>Fatandi V shows how chert was worked in short sequences that nonetheless aimed at consistent blanks.</p>



<p>Farther up the sequence, two Final Pleistocene sites, Toumboura I and Ravin de Sansandé, yielded microlithic industries <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10977785/" target="_blank" rel="noreferrer noopener">dated</a> between about 19,000 and 12,000 years ago. </p>



<p>Those assemblages emphasize small geometric pieces made from locally available stones like chert and quartz.</p>



<p>Ceramics appear early in the region, but not yet at RBX-1. <a href="https://www.cambridge.org/core/journals/antiquity/article/emergence-of-pottery-in-africa-during-the-tenth-millennium-cal-bc-new-evidence-from-ounjougou-mali/EC383CF3E1B961102319433214C6E034" target="_blank" rel="noreferrer noopener">Evidence</a> from Ounjougou in Mali shows pottery before 9400 BC, tied to wetter conditions and new subsistence choices. </p>



<p>That timeline helps frame RBX-1 as a late aceramic LSA snapshot, even though pottery existed elsewhere.</p>



<h2 class="wp-block-heading" id="h-quartz-tool-skills-and-choices">Quartz tool skills and choices</h2>



<p>The quartz at RBX-1 is unusually homogeneous, likely selected from nearby veins for quality. Cores were managed to keep convexities stable, so makers could pull off straight-edged, repeatable blanks with minimal waste.</p>



<p>Many flakes are small and angular, which is typical for quartz. The best products, however, hit narrow windows of geometry and thickness. That degree of control is hard to fake and shows learned technique passed within a group.</p>



<p>Everything points to a short visit focused on production. There are no postholes, bones, or piles of mixed trash, just the hearth, the debris ring, and the blanks that did not make the cut.</p>



<p>The rest of the tool kit likely traveled to where game was hunted or where tasks like hafting and <a href="https://www.earth.com/news/stone-tools-over-1-million-years-old-were-made-by-an-unknown-human-ancestor/">maintenance</a> took place. In other words, RBX-1 records one job in a seasonal round, not the whole camp.</p>



<h2 class="wp-block-heading" id="h-regional-links-with-quartz-tools">Regional links with quartz tools</h2>



<p>The team notes links between RBX-1 and sites across the Sahelo-Sudanian <a href="https://www.wcs.org/our-work/regions/sudano-sahel" target="_blank" rel="noreferrer noopener">belt</a>, where open savanna, rivers, and seasonal movement shaped technology. </p>



<p>Comparisons suggest shared habits in how small cores were prepared and how interchangeable parts were produced.</p>



<p>That does not mean everything looked the same. Forest zone sites farther south often show less standardization and different choices, which could reflect contrasting environments and cultural traditions.</p>



<p>Archaeology in West Africa has to work with rare, fragile layers. When one survives with a hearth, microdebris, and intact plant traces, it can sharpen timelines and test ideas about climate, mobility, and technology.</p>



<p>RBX-1 gives students of prehistory something that is usually hard to find in this region. It is a clean slice of activity, anchored in time and space, and tied into a growing regional map of people and practices.&nbsp;</p>

Archaeologists uncover a 9,000-year-old quartz tool workshop

A new paper documents a 9,000-year-old quartz tool workshop and...

<p>In Uganda’s Kibale National Park, scientists have spent years doing the slow, unglamorous work of catching tiny wasps. The payoff is big: a clearer map of “dark biodiversity” - the vast share of species that are poorly known or not yet described - and practical clues for how to protect it before it disappears.</p>



<p>Most of Earth’s species have never been formally documented, making them easy to overlook in conservation plans. Biologists call these overlooked lineages “dark taxa.” They are especially abundant in tropical forests, where species, habitats, and ecological roles remain thinly studied.</p>



<p>The Biodiversity Unit at the <a href="https://www.utu.fi/en" target="_blank" rel="noreferrer noopener">University of Turku</a> has made a specialty of unveiling this hidden diversity, describing new species each year, and building tools to slow global biodiversity loss.</p>



<h2 class="wp-block-heading" id="h-a-living-lab-for-biodiversity">A living lab for biodiversity</h2>



<p>Kibale National Park offers a mosaic of habitats. These include tracts of largely undisturbed forest, areas recovering from past logging, and nearby farmland. That patchwork allowed researchers to ask a simple but powerful question: where, exactly, is the unknown diversity concentrated?</p>



<p>The team focused on ichneumonid <a href="https://www.earth.com/news/invasive-parasitic-wasps-quietly-crossed-oceans-now-thriving-in-u-s-oak-trees/">wasps</a> - one of the most diverse animal groups on the planet - and, within it, the subfamily Pimplinae.</p>



<p>These wasps don’t just buzz around flowers. They regulate other species by parasitizing the immature stages of insects and <a href="https://www.earth.com/news/fossil-with-spiders-brain-suggests-arachnids-originated-in-the-sea/">spiders</a>, linking them tightly to the health of entire food webs.</p>



<p>“Ichneumonids are a very poorly known taxon in Africa - we estimate that over half of the species we found are new to science,” said doctoral researcher Emil Österman. </p>



<p>With so little baseline knowledge for tropical ichneumonids, the team used long-term, standardized sampling to see how Pimplinae diversity is distributed across Kibale’s different habitats.</p>



<h2 class="wp-block-heading" id="h-wasps-link-species-and-ecosystems">Wasps link species and ecosystems</h2>



<p>Because parasitoid wasps sit high in food webs, they are sensitive to disruptions below them. If the insects and spiders they rely on decline, parasitoids tend to follow. </p>



<p>That sensitivity makes Pimplinae useful indicators: shifts in their richness and abundance often mirror broader changes in biodiversity. The new work confirms what many ecologists have suspected but struggled to quantify in tropical Africa. </p>



<p>“Many of our finds weren't unexpected, but we didn't have data based on long-term collecting in the field," said Tapani Hopkins, a researcher with the Biodiversity Unit. </p>



<p>"Now we can tell in greater detail how many more <a href="https://www.earth.com/news/new-owl-species-discovered-in-africa/">species</a> there are in natural forest, and to what extent disturbed or logged tropical forest can harbor species.”</p>



<h2 class="wp-block-heading" id="h-farmland-cannot-match-forest-life">Farmland cannot match forest life</h2>



<p>The headline result is encouraging for conservation: intact forest in Kibale harbors especially rich Pimplinae communities. Secondary forest that is regrowing after logging also supports far more species than adjacent farmland.</p>



<p>In other words, protecting remaining forest is essential, and letting disturbed forest recover pays real biodiversity dividends.</p>



<p>“Our results clearly show that African forest, including forest that is recovering from <a href="https://www.earth.com/news/rainforests-replanted-seedlings-after-logging-do-not-recover-well/">logging</a>, maintains a species-rich Pimplinae fauna compared to, say, nearby farmland," Österman said. "Species-rich habitats can be considered especially valuable in conserving unknown dark biodiversity.” </p>



<p>That matters for policy and on-the-ground management. If you want to safeguard the most unknown species, prioritize forests - and don’t write off recovering stands. They’re already doing important work.</p>



<h2 class="wp-block-heading" id="h-global-forests-store-hidden-diversity">Global forests store hidden diversity</h2>



<p>The team also asked a bigger biogeographic question: how does African tropical diversity stack up against the New World? </p>



<p>Drawing on their parallel long-term collections in western Amazonia and Brazil’s coastal forests, the researchers found hints that South American rainforests may host even higher Pimplinae richness than Africa. However, African forests still harbor a rich fauna.</p>



<p>“Conserving dark taxa effectively requires a detailed knowledge of how biodiversity is distributed, both locally and at a global scale,” said Professor Ilari E. Sääksjärvi, who leads the Biodiversity Unit.</p>



<p>The comparison underscores a simple lesson: tropical forests on multiple continents are irreplaceable reservoirs of poorly known life.</p>



<h2 class="wp-block-heading" id="h-forest-biodiversity-loss-accelerates">Forest biodiversity loss accelerates</h2>



<p>Parasitoid wasps are only one window into dark biodiversity. But they tell a familiar story: clearing or simplifying forests causes losses to ripple upward. Protecting or allowing forests to recover lets complex communities rebound - including species we haven’t named yet.</p>



<p>The Kibale study shows <a href="https://www.earth.com/news/biodiversity-leaks-conservation-efforts-may-shift-harm-elsewhere/">conservation</a> can succeed despite limited taxonomy: protect habitats that concentrate hidden diversity. It also highlights the value of patient, long-term fieldwork in places where biodiversity is vanishing fastest.</p>



<p>“We will continue our field studies at different tropical forest sites, because that is where biodiversity is disappearing especially quickly. It is a fight against time. When a rainforest is destroyed, we lose countless species which we know nothing about,” Sääksjärvi concluded.</p>



<p>The study is published in the journal <a href="https://resjournals.onlinelibrary.wiley.com/doi/10.1111/icad.70017" target="_blank" rel="noreferrer noopener"><em>Insect Conservation and Diversity</em></a><em>.</em></p>

Wasps shine a light on 'dark biodiversity' in rainforests

In Uganda’s Kibale National Park, scientists have spent years doing...

<p>More than 85 climate scientists filed a detailed rebuttal to a Department of Energy (DOE) report that downplays climate risks. The response argues the document misrepresents research and inflates uncertainty in ways that could mislead policy.</p>



<p>The stakes are high because the Environmental Protection Agency (<a href="https://www.epa.gov" target="_blank" rel="noreferrer noopener">EPA</a>) is weighing a rollback of the 2009 endangerment finding and has referenced the DOE <a href="https://sites.google.com/tamu.edu/doeresponse/home" target="_blank" rel="noreferrer noopener">report</a>. If finalized, that move could reshape rules for vehicles, power plants, and oil and gas.</p>



<h2 class="wp-block-heading" id="h-climate-report-disputed">Climate report disputed</h2>



<p>DOE released its <a href="https://www.energy.gov/sites/default/files/2025-07/DOE_Critical_Review_of_Impacts_of_GHG_Emissions_on_the_US_Climate_July_2025.pdf" target="_blank" rel="noreferrer noopener">report</a>, written by five authors known for contrarian views. The agency opened a public comment period and framed the document as a synthesis for decision makers.</p>



<p>Days later, EPA issued a <a href="https://www.epa.gov/newsreleases/epa-releases-proposal-rescind-obama-era-endangerment-finding-regulations-paved-way" target="_blank" rel="noreferrer noopener">proposal</a> to rescind the endangerment finding, and cited the DOE study as part of its justification. That connection turned a technical dispute into a live regulatory fight.</p>



<p>Led by <a href="https://artsci.tamu.edu/atmos-science/contact/profiles/andrew-dessler.html" target="_blank" rel="noreferrer noopener">Andrew Dessler</a> of Texas A&amp;M University, the reviewers set out to provide a public, point by point critique. They aimed to show where claims diverge from the broader peer reviewed literature.</p>



<h2 class="wp-block-heading" id="h-how-the-rebuttal-came-together">How the rebuttal came together</h2>



<p>The reviewer group consisted of more than 85 experts and produced a public review exceeding 400 pages. </p>



<p>They coordinated quickly to prevent errors from hardening into official guidance. They compared each disputed claim with the underlying papers and flagged omissions or misreadings. </p>



<p>"This report makes a mockery of <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">science</a>," stated Dessler. The submitted document also challenges the report’s portrayal of benefits from carbon dioxide and its treatment of extreme <a href="https://www.earth.com/news/protecting-forests-helps-birds-and-humans-in-many-ways/">weather</a>.</p>



<p>The authors call out selective citation, heavy emphasis on uncertainty, and errors in statistics. They argue that several sections omit recent results on sea level rise and heat extremes.</p>



<h2 class="wp-block-heading" id="h-experts-review-climate-report">Experts review climate report</h2>



<p>The American Meteorological Society (<a href="https://www.ametsoc.org/ams/" target="_blank" rel="noreferrer noopener">AMS</a>) issued a formal <a href="https://www.ametsoc.org/ams/about-ams/ams-statements/statements-of-the-ams-in-force/the-practice-and-assessment-of-science-five-foundational-flaws-in-the-department-of-energys-2025-climate-report/" target="_blank" rel="noreferrer noopener">statement</a> identifying five foundational flaws in the DOE report. The society said a small, non representative author group cannot credibly assess the breadth of evidence.</p>



<p>"Each of these flaws, alone, places the report at odds with scientific principles and practices," said the AMS. The statement points to cherry picking and extrapolations that do not follow from comprehensive consideration of the <a href="https://www.earth.com/news/climate-wins-in-2025-came-from-unexpected-places/">science</a>.</p>



<p>Major assessments, like the <a href="https://www.ipcc.ch/" target="_blank" rel="noreferrer noopener">IPCC</a> and the <a href="https://toolkit.climate.gov/NCA5" target="_blank" rel="noreferrer noopener">National Climate Assessment</a>, synthesize hundreds of studies across disciplines. That process builds consensus by weighing all the evidence, not a narrow slice of it.</p>



<h2 class="wp-block-heading" id="h-record-on-sea-level-and-risk">Record on sea level and risk</h2>



<p>Sea level along the U.S. coast is projected to rise about 10 to 12 inches by 2050, according to a 2022 NOAA <a href="https://www.noaa.gov/news-release/us-coastline-to-see-up-to-foot-of-sea-level-rise-by-2050" target="_blank" rel="noreferrer noopener">report</a>. </p>



<p>That amount would roughly match the increase of the prior century and would raise the frequency of damaging coastal floods.</p>



<p>These projections rest on tide gauges, satellite measurements, and climate models, plus physics based understanding of melting land ice. </p>



<p>They also account for regional differences caused by land motion and ocean circulation.</p>



<p><a href="https://www.earth.com/news/forests-are-not-adapting-fast-enough-to-climate-change/">Communities</a> will face higher baseline water levels that make storms more destructive. Ports, bases, and neighborhoods will need plans that fit this trajectory, not assumptions that minimize it.</p>



<h2 class="wp-block-heading" id="h-track-record-of-climate-models">Track record of climate models</h2>



<p>A 2020 peer reviewed <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2019GL085378" target="_blank" rel="noreferrer noopener">study</a> compared decades of historical model projections with observed global temperatures. It found the models were generally accurate once evaluated against the emissions that actually occurred.</p>



<p>That result speaks directly to claims that models exaggerate <a href="https://www.earth.com/news/earth-is-just-three-years-away-from-dangerous-carbon-milestone/">warming</a>. While uncertainties remain about regional details, the physics behind greenhouse gas warming has performed well in retrospective tests.</p>



<p>Confidence in the big picture rests on measurements and skill tests, not on selective charts. When models are checked against reality, they give policymakers usable signals about risk.</p>



<h2 class="wp-block-heading" id="h-climate-report-shapes-policy">Climate report shapes policy</h2>



<p>EPA’s move puts the DOE document into the legal record, where it could influence standards for vehicles, power plants, and industrial sources. </p>



<p>Public comments, independent reviews, and court scrutiny will determine how much weight it carries.</p>



<p>For people outside Washington, the practical question is whether rules align with what the evidence shows. Health and infrastructure decisions depend on accurate readings of <a href="https://www.earth.com/news/wealthy-elite-responsible-for-majority-of-global-climate-warming/">heat</a>, rainfall, and sea level rise trends.</p>



<p>Scientists are not asking for certainty, only for decisions rooted in well established measurements and validated methods. Studies that test past <a href="https://www.earth.com/news/forests-are-lagging-centuries-behind-in-climate-adaptation/">projections</a> against outcomes help keep those decisions on solid ground.</p>

Over 85 environmental scientists claim the US government's new climate report is 'misleading'

More than 85 climate scientists filed a detailed rebuttal to...

<p>When people imagine grasslands, they often picture bison herds stretching to the horizon. These giant animals once ruled the Great Plains, shaping the land with their grazing. But size is not everything.</p>



<p>A new study shows that the smallest herbivores, prairie dogs and grasshoppers, do more for nutrient cycling than the mighty bison or cattle.</p>



<p>The research, led&nbsp;by scientists from the Smithsonian’s National Zoo and Conservation Biology Institute (<a href="https://nationalzoo.si.edu" target="_blank" rel="noreferrer noopener">NZCBI</a>), reveals a surprising truth. The tiniest <a href="https://www.earth.com/news/grasslands-are-racing-to-adapt-to-climate-shifts/">animals</a> can have the biggest impact on how nutrients move through grassland soil and plants.</p>



<h2 class="wp-block-heading" id="h-why-grasslands-matter">Why grasslands matter</h2>



<p>Grasslands cover 40 percent of Earth’s land. They store carbon, protect soil, and support biodiversity. Yet they remain among the planet’s most threatened ecosystems.</p>



<p>Farming and ranching have taken over large areas. Development has carved up habitats and replaced native grasses with crops or invasive plants. The result is fragile soil, fewer species, and land that struggles to recover after droughts or fires.</p>



<p>In North America, the Great Plains once stretched endlessly. Bison herds darkened the horizon. Prairie dogs dug their towns across vast distances. Today, those numbers have collapsed. Both species survive at just one or two percent of their former abundance. </p>



<p>This loss changed how the grasslands <a href="https://www.earth.com/news/grasslands-crucial-role-global-agriculture-environment-ecosystems/">function</a>. Without constant grazing or burrowing, the soil misses some of the recycling and mixing it once relied on. Plants grow differently. Nutrients move more slowly. The system no longer works the same.</p>



<h2 class="wp-block-heading" id="h-which-animals-support-grasslands">Which animals support grasslands?</h2>



<p>To see what remains, the researchers focused on northeast Montana. This region still holds stretches of shortgrass prairie. It also shows how people use the land in many ways. </p>



<p>Some areas are set aside for conservation. Others support ranching or crop farming. Together, they form a patchwork landscape. That mix gave scientists a chance to study real conditions rather than isolated sites. </p>



<p>The team selected 15 locations. By comparing them, the researchers could see how herbivores - from prairie dogs to cattle - shape soil and grass today.</p>



<h2 class="wp-block-heading" id="h-the-green-food-web">The green food web</h2>



<p>“Herbivores contribute to the green food web by turning plant tissues into urine and dung that provide new plant growth with readily available nutrients,” said Ellen Welti, NZCBI community ecologist and the study’s senior author. </p>



<p>“This cycles nutrients at a faster rate than the brown food web, where plant tissues slowly senesce and degrade before nutrients become available for uptake by future plants.”</p>



<p>The cycle is faster and more direct when small animals do the work. Prairie dogs and grasshoppers, in particular, push nutrients back into the soil quickly, changing the landscape in ways the larger grazers do not.</p>



<h2 class="wp-block-heading" id="h-prairie-dogs-have-a-big-influence">Prairie dogs have a big influence </h2>



<p>Prairie dogs had the biggest <a href="https://www.earth.com/news/restored-grasslands-bring-more-peace-to-africa/">influence</a>. Their colonies held higher levels of carbon and nitrogen in the soil than surrounding grasslands. </p>



<p>Their burrows moved nutrients deeper into the ground, while their waste enriched plants with nitrogen, potassium, and magnesium.</p>



<p>These animals don’t just nibble on grass. By digging, depositing, and living in dense groups, they create hot spots of fertility. The land around a prairie dog town becomes richer and more productive than areas without them.</p>



<h2 class="wp-block-heading" id="h-tiny-animals-that-shape-grasslands">Tiny animals that shape grasslands</h2>



<p>Grasshoppers also left their mark. Their feeding increased phosphorus in the soil, an essential nutrient for plant growth. But they also shaped the rhythm of the prairie. Plant biomass peaked in mid-summer, then declined sharply. That pattern lined up with the grasshopper life cycle.</p>



<p>Nymphs hatched in spring, barely eating at first. By late summer, they had grown into hungry adults, devouring plants at a much higher rate. </p>



<p>Bison and cattle grazed more steadily through the season, but grasshoppers created these dramatic seasonal swings - influencing not only plant growth but also food availability for other prairie species.</p>



<h2 class="wp-block-heading" id="h-interactions-that-matter">Interactions that matter</h2>



<p>“This study shows there are many different interactions occurring between herbivores and the greater grassland ecosystem,” said Julie Rebh, the study’s lead author who conducted the research as an intern at NZCBI. </p>



<p>“While the presence of some smaller herbivores such as prairie dogs and grasshoppers may not be as obvious, the impact they have on grassland ecology is considerable.”</p>



<p>The research makes one point clear: ecosystems rely on many actors, not just the most visible ones. Big animals shape the landscape in one way, but the smallest can speed up cycles and create pockets of fertility that keep the system running.</p>



<h2 class="wp-block-heading" id="h-a-broader-view-of-healthy-grasslands">A broader view of healthy grasslands </h2>



<p>Conservation often centers on iconic species like bison. But this study argues for a more complete approach. </p>



<p>Prairie dogs and grasshoppers may not inspire awe, but they keep nutrients flowing. Without them, grasslands risk losing part of their engine.</p>



<p>Healthy grasslands need both large grazers and small recyclers. Together they keep soil, plants, and animals in balance. Protecting them protects the whole system. It also ensures resilience, biodiversity, and survival under pressure.</p>



<p>The study is published in the journal <a href="https://esajournals.onlinelibrary.wiley.com/doi/10.1002/ecy.70192" target="_blank" rel="noreferrer noopener"><em>Ecology</em></a>.</p>

Surprisingly small animals are powerful grassland engineers

When people imagine grasslands, they often picture bison herds stretching...

<p>Polar ice is rapidly vanishing in both Antarctica and the South Pole, and the world keeps circling back to the same question: Can we use technology to stop it? </p>



<p>A new review takes a hard look at five of the boldest proposals for slowing polar melt - and comes back with a clear answer: not yet, and maybe not ever.</p>



<p>The stakes are rising fast. In 2025, Arctic sea ice hit its lowest winter maximum on record, according to the National Snow and Ice Data Center (<a href="https://nsidc.org/home" target="_blank" rel="noreferrer noopener">NSIDC</a>). </p>



<p>That trend highlights why people keep dreaming up big fixes - and why scientists are now asking tough questions about whether those fixes could actually work.</p>



<p>Led by Professor Martin Siegert of the <a href="https://www.exeter.ac.uk/">University of Exeter</a>, the team evaluated the five ideas against six yardsticks: effectiveness, feasibility, scale and timing, environmental risk, cost, and governance. </p>



<p>Their conclusion is sobering - especially for the Arctic and Antarctic, where even small missteps can cascade into major problems.</p>



<h2 class="wp-block-heading" id="h-big-ideas-bigger-costs">Big ideas, bigger costs</h2>



<p>The five ideas are simple to list and hard to pull off. They include <a href="https://www.earth.com/news/how-small-aerosols-influence-cloud-formation/">stratospheric aerosol</a> injection, which means spraying reflective particles high in the atmosphere, and seabed curtains to block warm currents from ice shelves.</p>



<p>Other ideas are sea ice management by boosting albedo with beads or by thickening ice, basal water removal under glaciers, and ocean iron fertilization (OIF) to stimulate <a href="https://www.earth.com/news/plankton-at-risk-global-warming-threatens-the-oceans-lifeline/">plankton</a> that carry carbon to the depth.</p>



<p>Cost alone should make readers pause. This analysis estimates that an 80-kilometer (about 50-mile) sea curtain would cost roughly 80 billion dollars over ten years. That figure comes before ongoing maintenance and unforeseen impacts are counted.</p>



<p>"Mid-century is approaching, but our time, money, and expertise is split between evidence-backed net zero efforts and speculative geoengineering projects," said Professor Siegert.</p>



<h2 class="wp-block-heading" id="h-aerosols-can-t-save-the-polar-ice">Aerosols can’t save the polar ice</h2>



<p><a href="https://www.earth.com/news/aerosol-formation-earths-lower-atmosphere-soas/">Stratospheric aerosol</a> injection sounds straightforward: add particles like sulfur dioxide high in the stratosphere to reflect sunlight.</p>



<p>Over the poles it runs into physics, since winter darkness removes sunlight for months and cold-season circulation flushes aerosols out faster.</p>



<p>Even when the sun is up, snow and ice already reflect a lot of light, which weakens the effect. </p>



<p>The review also flags known risks, including ozone loss, shifts in rainfall, and the chance of rapid warming if injections stop after years of masking greenhouse heating.</p>



<h2 class="wp-block-heading" id="h-thicker-ice-plan-falls-short">Thicker ice plan falls short</h2>



<p>One attention-grabbing idea is to scatter tiny hollow glass microspheres over first-year <a href="https://www.earth.com/news/abrupt-collapse-of-arctic-sea-ice-may-come-with-little-warning/">sea ice</a> to reflect more light. </p>



<p>A 2022 paper calculated that roughly 360 megatons of beads per year would be needed and found the beads can darken some surfaces enough to accelerate ice loss.</p>



<p>Support for that approach also sagged outside the lab. A 2025 announcement from the Arctic Ice Project said the nonprofit was winding down after ecotoxicology tests raised potential food web risks.</p>



<p>What about thickening sea ice by pumping seawater onto the surface so it freezes? </p>



<p>The review points out a practical wall here too, since it would mean deploying and maintaining huge numbers of devices across drifting, breaking ice in brutal conditions for years.</p>



<h2 class="wp-block-heading" id="h-glacier-pumping-hits-hard-wall">Glacier pumping hits hard wall</h2>



<p><a href="https://www.earth.com/news/glaciers-from-the-rockies-to-the-alps-are-melting-much-faster-than-expected/">Speeding glaciers</a> depend partly on water at the base that reduces friction. Drilling through miles of moving ice and pumping out subglacial water across wide areas are a massive challenge.</p>



<p>Keeping the holes from freezing shut demands power, logistics, and precision that exceed current polar field capacity.</p>



<p>Fertilizing the <a href="https://www.earth.com/news/carbon-storage-mystery-emerges-in-the-southern-ocean/">Southern Ocean</a> with iron to grow more plankton has been tested many times. A policy brief notes that only one ship experiment - the <a href="https://epic.awi.de/id/eprint/15162/" target="_blank" rel="noreferrer noopener">European Iron Fertilization Experiment</a> - saw strong carbon export to more than 9,800 feet, where storage could last centuries. </p>



<p>It also found that nitrous oxide produced during remineralization can offset 5 to more than 40 percent of any carbon gains.</p>



<p>Even if results looked better, governance would still be a hurdle. The London Convention’s 2013 amendment restricts large-scale ocean fertilization to legitimate research, not carbon markets. </p>



<p>The review adds that the <a href="https://www.ats.aq/index_e.html" target="_blank" rel="noreferrer noopener">Antarctic Treaty System</a> would require strict environmental review for most polar interventions.</p>



<h2 class="wp-block-heading" id="h-harsh-realities-of-polar-ice-testing">Harsh realities of polar ice testing</h2>



<p>Polar work windows are short, travel distances are long, and <a href="https://www.earth.com/news/lightning-near-the-north-pole-signals-major-climate-shifts/">storms</a> and sea ice can cancel whole seasons. </p>



<p>That is before counting iceberg hazards, darkness, and the difficulty of powering heavy equipment cleanly without leaving black carbon on the snow.</p>



<p>Scale also defeats many of these ideas. The ocean and ice do not respect neat borders, so diverting warm water from one polar ice shelf can steer it toward another. </p>



<p>Slowing one fast-flowing glacier can also redirect stress or subglacial water and speed up a neighbor.</p>



<h2 class="wp-block-heading" id="h-cutting-co2-still-works-best">Cutting CO2 still works best</h2>



<p>The most reliable lever we have is still cutting carbon dioxide quickly. </p>



<p>The review emphasizes that temperatures tend to stabilize within about two decades after <a href="https://www.earth.com/news/green-technology-is-urgently-needed-to-save-the-climate/">net-zero CO2</a>, which slows the drivers of polar ice loss and gives ecosystems and communities a fighting chance.</p>



<p>Protecting polar biodiversity and local livelihoods also means expanding and enforcing strong protected areas. </p>

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air"><strong>Invisible threat in urban air</strong></h2>



<p>City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.</p>



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge"><strong>Disturbing connections emerge</strong></h2>



<p>Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.</p>



<h2 class="wp-block-heading" id="h-timing-matters"><strong>Timing matters</strong></h2>



<p>The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.</p>



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns"><strong>Genetic vulnerability patterns</strong></h2>



<p>Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.</p>



<h2 class="wp-block-heading" id="h-public-health-implications"><strong>Public health implications</strong></h2>



<p>These findings, published in <em><a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a></em>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.</p>



<p>As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.</p>

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



<p>Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.</p>



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



<p>The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.</p>



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



<p>At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.</p>



<p>"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.</p>



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



<p>The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.</p>



<p>The research, published in <em><a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a></em> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.</p>

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



<p>Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.</p>



<h2 class="wp-block-heading" id="h-the-discovery">The discovery</h2>



<p>Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.</p>



<p>Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."</p>



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



<p>The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.</p>



<p>Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.</p>



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



<p>Published in the journal <em><a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a></em>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.</p>

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



<h2 class="wp-block-heading" id="h-a-contrasting-climate-response">A contrasting climate response</h2>



<p>Most coastal towns are <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">preparing for higher sea levels</a>, but <a href="https://www.earth.com/news/greenland-no-longer-has-to-worry-about-rising-sea-levels/" target="_blank" rel="noreferrer noopener">Greenland presents</a> a different scenario during climate change. The ground there is rising at a remarkable rate. Over the past decade, some areas have lifted about 20 centimeters, which translates to roughly 2 meters per century. This rate significantly exceeds current projections for sea level rise.</p>



<h2 class="wp-block-heading" id="h-geological-rebound-process-through-climate-change">Geological rebound process through climate change</h2>



<p>The mechanism behind this phenomenon is straightforward. As the ice sheet melts, the immense weight is removed from the bedrock, causing the land to rebound upward. This process resembles the way compressed material springs back when pressure is released.</p>



<h2 class="wp-block-heading" id="h-scientific-monitoring-networks">Scientific monitoring networks</h2>



<p>Researchers at the <a href="https://www.dtu.dk/english/" target="_blank" rel="noreferrer noopener">Technical University of Denmark</a> are documenting this uplift using the GNET network, consisting of 61 GPS stations positioned around Greenland's coast. These sensors can detect movement with millimeter precision, providing detailed measurements of the ongoing changes.</p>



<p>The data reveal that current uplift rates exceed the gradual rebound occurring since the last ice age ended approximately 12,000 years ago. This acceleration corresponds directly with increased ice sheet melting rates.</p>



<h2 class="wp-block-heading" id="h-coastal-transformation">Coastal Transformation</h2>



<p>This uplift is actively reshaping Greenland's coastline. New islands and rocky formations, called "skerries," are emerging as previously submerged land surfaces rise above the water level. This represents a notable contrast to global concerns about rising seas.</p>



<p>The study, published in Geophysical Research Letters, demonstrates the varied regional impacts of climate change. While many locations face rising water levels, Greenland's bedrock is literally rising above the surrounding seas.</p>



<p>The full study was recently published in <em><a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL104851" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a></em>.</p>

<h2 class="wp-block-heading" id="h-ai-agent-training-transforms-the-workplace-fear-factor-into-a-competitive-advantage">AI agent training transforms the workplace 'fear factor' into a competitive advantage</h2>



<p>Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.</p>



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



<p>A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.</p>



<p>Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.</p>



<p>Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents".  In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively.   MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.</p>



<p>MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization.  The training provided by MindStudio is applicable across other AI Agent building platforms as well.</p>



<h2 class="wp-block-heading" id="h-revolutionary-productivity-through-focused-learning">Revolutionary productivity through focused learning</h2>



<p>Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.</p>



<p>Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.</p>



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



<p>The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.</p>



<p>A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.</p>



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



<p>Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.</p>



<p>This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.</p>



<h2 class="wp-block-heading" id="h-financial-benefits-of-increased-retention">Financial benefits of increased retention</h2>



<p>The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.</p>



<p>PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.</p>



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



<p>AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.</p>



<p>In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.</p>



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>



<p>The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.</p>



<p>As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.</p>



<p>The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.</p>

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



<p>The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.</p>



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



<p>Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.</p>



<p>The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.</p>



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



<p>The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.</p>



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



<p>While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.</p>



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



<p>As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.</p>



<p>The study is published in the journal&nbsp;<a href="http://dx.doi.org/10.1038/s41467-023-44335-3" target="_blank" rel="noreferrer noopener"><em>Nature Communications</em></a>.</p>
