Fender's blue butterfly is an endangered subspecies of butterfly endemic to the Willamette Valley of northwestern Oregon, United States. The subspecies was first documented in the 1920s and was described to science in 1931 by biologist Ralph Macy. He named it for his friend, Kenneth Fender, an entomologist and mail carrier. The subspecies was not seen after the 1930s and was presumed extinct. Small populations were rediscovered in 1989. Its eponym, Fender, had died nine years earlier. In January 2000, Fender's blue butterfly was added to the Endangered Species List by the U.S. Fish and Wildlife Service. The largest known populations now exist in the Baskett Slough National Wildlife Refuge. A 2014 study reintroduced this subspecies to William L. Finley National Wildlife Refuge. The potential range of the butterfly extends from south and west of Portland, OR to south of Eugene, OR.

Ictalurus pricei, the Yaqui catfish, is a species of North American freshwater catfish native to Mexico and Arizona. The Yaqui catfish historically occurred in San Bernardino Creek as far up as San Bernardino Ranch, Arizona. An introduced population of catfish existed in the Monkey Springs Reservoir system near Patagonia, Arizona, from 1899 until the 1950s. The stock presumably came from the Rio Sonora basin of Sonora, Mexico, where the species still lives.<a href="https://en.wikipedia.org/wiki/Ictalurus_pricei#cite_note-5">[5]</a> A small population of 350 fish has been reintroduced into the Rio Yaqui on the northernmost portion of the San Bernardino National Wildlife Refuge in November 1997.

NatureServe Explorer is a product of NatureServe in collaboration with the Natural Heritage Network. The rufous hare- wallaby (Lagorchestes hirsutus), also known as the mala, is a small macropod found in Australia. It was formerly widely distributed across the western half of the continent, but naturally occurring populations are now confined to Bernier Island and Dorre Island Islands off Western Australia. Although once widespread in the central and western deserts, predation by feral cats and foxes, and destructive wildfires, caused the last wild population on mainland Australia to go extinct in the early 1990s. Despite its extinction in the wild, the mainland subspecies persisted in captivity. The species, which is currently classified as vulnerable, has rufous-grey fur and is the smallest hare-wallaby, weighing just 800-1,600 grams. It is a solitary nocturnal herbivore that feeds on herbs, leaves and seeds.

Wood looks simple, but it’s a tricky material. Inside every tree are long cellulose fibers, helper sugars called hemicellulose, and a stiff, brown binder known as lignin. 



That mix lets trees grow tall and stay standing through wind and weather. It also makes wood tough to reshape into high-performance beams and panels.



Factories usually force wood into shape with chemicals and heat. They strip out some lignin first, then compress what remains into a dense, strong material. 



That step consumes energy, costs money, and generates waste. A team of researchers set out to avoid it.



<h2 class="wp-block-heading" id="h-engineered-wood-and-lignin">Engineered wood and lignin</h2>



<a href="https://www.earth.com/news/poplar-trees-changed-their-chemistry-to-survive/">Lignin</a> is great for trees and a challenge for manufacturers. It’s the glue that stiffens cell walls and blocks pests. It resists many industrial treatments. 



Take out some lignin and you can pack <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/cellulose-fiber" target="_blank" rel="noreferrer noopener">cellulose fibers</a> closer, which boosts strength. The usual methods require harsh chemicals and high temperatures.



Engineered wood has become a cleaner alternative to steel and concrete in many projects. It’s lighter and can carry serious loads when densified. 



To keep that promise, the industry needs cleaner steps from the forest to the factory floor.



<h2 class="wp-block-heading" id="h-genetics-and-wood-engineering">Genetics and wood engineering</h2>



Researchers at the <a href="https://umd.edu/" target="_blank" rel="noreferrer noopener">University of Maryland</a> genetically modified poplar trees to produce high-performance structural wood with fewer chemicals and less energy-intensive processing.



“We are very excited to demonstrate an innovative approach that combines genetic engineering and wood engineering, to sustainably sequester and store carbon in a resilient super wood form,” explained <a href="https://agnr.umd.edu/about/directory/yiping-qi/" target="_blank" rel="noreferrer noopener">Yiping Qi</a>, a professor in the Department of Plant Science and Landscape Architecture (<a href="https://psla.umd.edu/node/1/" target="_blank" rel="noreferrer noopener">PSLA</a>) at the University of Maryland.



Instead of modifying wood after the tree grows, the team asked a simple question: could the tree grow wood that’s easier to densify from the start? 



They chose poplar, a fast-growing research workhorse that also shows up in real products. Using precise gene editing, they adjusted the tree’s lignin pathway without undermining growth.



They targeted one gene - <a href="https://pubmed.ncbi.nlm.nih.gov/26491147/" target="_blank" rel="noreferrer noopener">4CL1</a> - within the pathway cells use to make lignin. By switching off 4CL1, the trees produced slightly less lignin, but maintained normal development under controlled conditions. 



That small change opened a new option in the factory: skipping the chemical delignification step.



<h2 class="wp-block-heading" id="h-how-the-gene-edit-works">How the gene edit works</h2>



The tool was base editing, a form of <a href="https://www.earth.com/news/worlds-first-gene-edited-spiders-spin-red-silk/">CRISPR</a> that swaps one DNA letter for another at a chosen spot. It doesn’t slice the genome; it rewrites a letter with precision. 



In this case, the edit focused on 4CL1 while minimizing changes elsewhere in the genome.



With the wood in hand, the team soaked it in water and then applied heat and pressure to densify it. 



When cellulose fibers line up and move closer together, mechanical strength climbs. The process relies less on solvents and more on physical compaction.

<h2 class="wp-block-heading" id="h-putting-it-to-the-test">Putting it to the test</h2>



The densified wood from the edited poplars reached <a href="https://www.earth.com/news/booster-plant-gene-discovery-amplifies-plant-growth-up-to-200-percent/">strength levels</a> comparable to those of panels made with conventional chemical treatments. 



The researchers measured lignin levels approximately one-eighth lower than in unedited controls. Growth remained healthy in greenhouse tests, which matters because factory gains aren’t worth much if the tree can’t thrive.



Skipping the chemical bath meant fewer inputs and less waste while still yielding structural-grade material. 



The balance was key: reduce lignin just enough to ease processing, not so much that the tree loses toughness in the wild.



<h2 class="wp-block-heading" id="h-co2-and-engineered-wood">CO2 and engineered wood</h2>



Buildings are a major source of global <a href="https://www.earth.com/news/ai-just-created-concrete-that-could-reverse-climate-damage/">carbon emissions</a>, driven by materials like steel and concrete. 



Engineered wood can help by replacing part of that footprint with lighter structural components that store carbon for decades. Cleaner processing tightens the loop further, cutting energy use and reducing waste streams.



“Carbon sequestration is critical in our fight against climate change, and such engineered wood may find many uses in the future bioeconomy,” Qi added.



If mills can avoid harsh solvents and still press wood into high-strength beams and panels, the path to <a href="https://www.earth.com/news/construction-materials-could-store-carbon-in-homes-and-buildings-helping-the-climate/">lower-carbon construction</a> gets wider. 



The approach starts upstream in the forest, not just on the factory line. It tunes the raw material so it cooperates when densified.



<h2 class="wp-block-heading" id="h-next-steps-underway">Next steps underway</h2>



Greenhouse results look good, but forests are tougher proving grounds. Wind, pests, and seasons test wood in ways a lab cannot. 



Longer field trials will show whether reduced-lignin trees keep their strength and resilience outdoors. Another step is to try similar edits in pine, spruce, or eucalyptus, which dominate many timber markets.



Policy will shape the path. Base-edited trees do not carry added foreign genes; they contain single-letter changes to DNA already present. 



Many regulators treat that differently from classic GMOs, but rules vary by country. Because forestry spans long life cycles and open landscapes, regulators will likely require careful, staged reviews before any commercial rollout.



<h2 class="wp-block-heading" id="h-super-wood-and-earth-s-future">"Super wood" and Earth's future</h2>



This study shows that small genetic changes can simplify manufacturing while maintaining performance. The edit doesn’t erase lignin; it tunes it. 



The result is densified “super wood” that matches the strength of chemically treated material while avoiding the delignification step.



This is a careful blend of biology and materials science aimed at a practical target: strong, reliable wood that stores carbon and reduces the mess of production. 



If future field tests and policy steps go well, smarter forests could feed cleaner factories - and sturdier buildings - for years to come.

Scientists create 'super wood' from gene-edited trees and claim it will change everything

Wood looks simple, but it’s a tricky material. Inside every...

Plants cannot move to chase comfort, yet they still need to choose the right season to reproduce. A new study explains how a small plant uses blue light and cool air together to decide when to flower.



A research team led by Adam Seluzicki from the <a href="https://www.salk.edu/" target="_blank" rel="noreferrer noopener">Salk Institute for Biological Studies</a> mapped a genetic switch that listens for both signals at once. 



The study shows how one pathway senses blue light and another senses low temperature, and how they meet to control the transition to <a href="https://www.earth.com/news/flowering-plants-appeared-two-million-years-earlier-than-we-thought/">flowering</a>.



<h2 class="wp-block-heading" id="h-when-do-plants-start-flowering">When do plants start flowering?</h2>



Arabidopsis thaliana uses a blue light sensor called PHOT2 and a helper protein named NPH3 to read light signals. When the air is cool, a temperature responsive gene switch called CAMTA2 turns on another gene called <a href="https://www.sciencedirect.com/science/article/abs/pii/S0176161716302024" target="_blank" rel="noreferrer noopener">EHB1</a>.



The EHB1 gene then connects with NPH3, which brings the light and temperature signals together. The plant starts flowering only when both <a href="https://www.earth.com/news/nasa-tracks-changes-in-seasonal-flower-cycles-and-migration-patterns-from-the-air/">conditions</a> are met - blue light is present and the air is cool.



“Here we show that signals from the PHOTOTROPIN2 (PHOT2) blue photoreceptor combine with low temperature information to control flowering,” wrote Seluzicki.



<h2 class="wp-block-heading" id="h-the-timing-of-plant-flowering">The timing of plant flowering </h2>



Seasonal timing depends on multiple cues, not a single trigger. A recent <a href="https://onlinelibrary.wiley.com/doi/10.1111/pce.15678?af=R" target="_blank" rel="noreferrer noopener">review</a> outlines how plants sense temperature through changes in cell membranes, protein activity, and chromatin.



Day length, light color, and light intensity also shape <a href="https://www.earth.com/news/a-new-window-into-the-early-evolution-of-flowering-plants/">flowering</a>. These signals run through several networks at once, which is why combining them gives a more reliable readout than using either one alone.



<h3 class="wp-block-heading" id="h-blue-light-pathway">Blue light pathway</h3>



Plant <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC8630751/" target="_blank" rel="noreferrer noopener">photoreceptors</a> are proteins that detect wavelengths and pass along messages. The blue light sensor PHOT2, located at the cell membrane, helps direct growth and movement.



NPH3 works after the PHOT proteins and helps control how their signals are used. In the system described in the new research, NPH3 acts like the main hub. It changes its response depending on what the temperature pathway is doing.



<h3 class="wp-block-heading" id="h-temperature-pathway">Temperature pathway</h3>



When it is cool, the gene switch CAMTA2 becomes active. It turns on the gene EHB1, which then slows down NPH3 at the right moment.



Other studies on NPH3 show that its behavior depends on where it is in the cell and how it is modified. These details explain why EHB1’s link with NPH3 can change the balance of <a href="https://www.earth.com/news/seasonal-timing-can-change-quickly-over-short-distances/">signals</a> that decide when the plant flowers.



<h2 class="wp-block-heading" id="h-revelations-about-plant-flowering">Revelations about plant flowering</h2>



When the days were long and the air was cool, plants without PHOT2 grew more leaves before making flowers compared to normal plants. At warmer temperatures, this delay disappeared, showing that PHOT2 matters most in cooler conditions.



Previous studies found that PHOT2 and other phototropins help plants adjust to daily cold at sunrise. This supports the idea that blue light sensors play an important role in how plants respond to low temperatures. 



These results together make the connection between PHOT2, CAMTA2, NPH3, and EHB1 more convincing.



<h2 class="wp-block-heading" id="h-how-the-plant-system-functions">How the plant system functions</h2>



PHOT2 picks up blue light and passes the signal to NPH3. When it is cold, CAMTA2 turns on EHB1, and EHB1 connects with NPH3 to help control flowering.



In warm conditions, CAMTA2 does not activate EHB1 the same way, so the system works differently. In that state, flowering is not delayed, which explains why the effect only shows up in cooler weather.



Arabidopsis uses a signal called FT, also known as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC5654465/" target="_blank" rel="noreferrer noopener">florigen</a>, to send the message from the leaves to the shoot, where flowers develop. FT levels go up when day length and light quality favor flowering, and this signal also takes temperature into account.



Other blue light sensors besides PHOT proteins also affect flowering time. One called <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC6670086/" target="_blank" rel="noreferrer noopener">FKF1</a> works with the plant’s internal clock and a protein named CONSTANS to boost FT under the right day length. This shows that several blue light pathways feed into the same flowering signal.



<h2 class="wp-block-heading" id="h-what-sets-this-research-apart">What sets this research apart</h2>



Most past studies linked flowering to sensors called cryptochromes, phytochromes, or to the FT pathway. 



This new research shows that PHOT2, a sensor usually known for guiding growth, moving chloroplasts, and opening stomata, also plays a role in flowering when it is cool.



In addition, the study shows how temperature signals through CAMTA2 and EHB1 connect directly to NPH3, the hub of the light pathway. This direct link explains why flowering is affected only when both light and temperature signals are present.



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



Climate change is altering seasonal light patterns and nighttime temperatures in many places. A system that only triggers when both signals line up can help prevent plants from flowering too early in unpredictable springs.



The Salk team’s results highlight genes that plant breeders could adjust to control flowering in cooler conditions. 



Small changes in PHOT2, CAMTA2, NPH3, or EHB1 could help time flowering to match better conditions for pollination and seed production.



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



Future work can map where, within a leaf, this module is most active. Tissue specific data would show how the signal flows into FT production and transport.



It will also be important to test crop species. If a similar module exists in brassicas or cereals, targeted edits could help stabilize yields when cold snaps interrupt the start of the growing season.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-025-62194-y" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Plant flowering is triggered by blue light and cool air

Plants cannot move to chase comfort, yet they still need...

Earth’s seasons are not a single global script. They vary from place to place, sometimes over short distances. 



In a new global study, experts used 20 years of satellite observations to map when plants grow and rest through the year. They found many spots where neighboring <a href="https://www.earth.com/news/earth-day-2025-our-power-our-planet/">landscapes</a> run on different clocks.



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



The research was led by Drew E. Terasaki Hart of the University of California, <a href="https://www.berkeley.edu/" target="_blank" rel="noreferrer noopener">Berkeley</a>. The goal was to stitch together a worldwide picture of seasonal timing. The team focused on how plant communities rise and fall in activity across each year.



Scientists call this timing phenology, and when it is mapped from space across landscapes it is called land surface phenology. The approach sidesteps guesswork and lets researchers see real signals of growth and pause across ecosystems.



Near-infrared reflectance of vegetation (NIRV) is closely linked with solar-induced chlorophyll fluorescence (SIF), which measures light re-emitted by plants during photosynthesis. Both NIRV and SIF provide reliable ways to track how much energy plants are capturing and using.



Because SIF changes in step with photosynthesis, it gives scientists a clear <a href="https://www.earth.com/news/earths-oceans-are-rapidly-changing-colors-matching-climate-predictions/">signal</a> of when plants are actively growing and when they are at rest.



<h2 class="wp-block-heading" id="h-seasons-out-of-sync">Seasons out of sync</h2>



The map shows many places where seasonal timing changes quickly over short distances. Hotspots stand out in Mediterranean climate zones and in tropical mountain regions, where terrain and winds shape local rain and cloud patterns.



In the U.S. Southwest, cities just about 100 miles apart can show very different annual <a href="https://www.earth.com/news/lightning-is-changing-the-atmosphere-in-surprising-ways/">rhythms</a> because one area leans on summer monsoon rains while another splits rain between winter and summer. 



Similar seasonal contrasts also appear along mountain slopes in South America and East Africa.



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



According to a 2017 <a href="https://pubmed.ncbi.nlm.nih.gov/28370658/" target="_blank" rel="noreferrer noopener">review</a>, when populations breed at different times, they meet less often and that can reduce gene flow and let differences stack up.&nbsp;



The new map links sharp timing breaks to measured differences in flowering dates and to genetic divergence in some species. That pattern hints that out-of-sync seasons can help build biodiversity over long timescales.



Agriculture feels these patterns in practical ways. In Colombia, growers plan around two distinct coffee harvest windows, one from October to December and another from March to June. Mountain ranges can flip the calendar across short drives, changing when cherries ripen and labor is needed.



“Our map predicts stark geographic differences in flowering timing and genetic relatedness across a wide variety of plant and animal species,” said Hart.



<h2 class="wp-block-heading" id="h-map-built-from-satellite-data">Map built from satellite data</h2>



The team analyzed two decades of satellite records and fit each pixel with a simple model of its average year. That model can capture single peaks or two peaks in plant activity, which is important in places with two rainy seasons.



The researchers measured how quickly seasonal timing changes across <a href="https://www.earth.com/news/earthcares-first-year-surprising-climate-clues-unveiled-from-space/">space</a>. Where that rate is high, nearby places are out of sync. 



Patterns point to shifting rainfall and minimum temperatures as the main drivers, especially where mountains steer air and moisture.



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



Wildlife that moves to follow food can get out of step if resources peak at different times across a landscape. Pollinators, seed dispersers, and migratory species may all feel the squeeze when timing shifts across short distances.



Managers can use these maps to spot regions where species are most likely to split into locally timed groups. That helps set priorities for conservation, seed sourcing, and habitat corridors that keep life stages connected.



<h2 class="wp-block-heading" id="h-climate-shifts-the-timing-of-seasons">Climate shifts the timing of seasons</h2>



Warming and shifting rainfall can move seasonal cues. In places where timing already varies a lot, small climatic nudges could tip species out of sync with food or mates. 



The new baseline makes it easier to flag unusual years and track how often they happen.



Land use matters too. Irrigation can create human-made timing that does not match nearby natural cycles. Understanding where that mismatch is strongest can guide smarter water use and crop planning.



<h2 class="wp-block-heading" id="h-clearer-plant-activity-signals">Clearer plant activity signals</h2>



NIRV and SIF help avoid a common pitfall of older vegetation metrics that can blur the signal in evergreen systems. 



NIRV filters out bright backgrounds, and SIF connects directly to chlorophyll activity, which tightens the link to photosynthesis.



The analysis does not depend on one sensor or one region. It draws strength from multiple data streams, long records, and simple math that holds up across biomes. That mix is what makes the global picture hang together.



<h2 class="wp-block-heading" id="h-seasonal-timing-shapes-biodiversity">Seasonal timing shapes biodiversity</h2>



Timing is a quiet kind of change. It rarely makes headlines, but it shapes whether young animals find food, whether flowers meet pollinators, and whether farms hit their harvest windows. 



Knowing where timing disagrees across short distances turns guesswork into preparation and planning.



The take-home is simple. Seasons still matter, but they do not line up the same way everywhere, and those differences can ripple through evolution, ecology, and economies.



The study is published in the journal <a href="https://www.nature.com/articles/s41586-025-09410-3" target="_blank" rel="noreferrer noopener">Nature</a>.

Seasonal timing can change quickly over short distances

Earth’s seasons are not a single global script. They vary...

Robots usually take orders from silicon chips and lines of code. In this project, the commands start in living tissue. The control signals come from mycelia - the branching underground networks that support mushrooms. 



These networks sense light, touch, chemicals, and temperature. They also produce tiny electrical pulses that carry information.



Researchers from <a href="https://www.engineering.cornell.edu/" target="_blank" rel="noreferrer noopener">Cornell University Engineering</a> learned to read those pulses without harming the organism or muddying the signal. They translated the rhythms into digital commands that set a robot’s movement. 



When the environment changed, the mycelia changed their electrical patterns, and the robot adjusted how it moved. That is sensorimotor control driven by a living system.



<h2 class="wp-block-heading" id="h-from-mushrooms-to-motion">From mushrooms to motion</h2>



The work comes from Cornell Engineering. After <a href="https://www.earth.com/news/mushroom-leather-mycelium-latest-eco-friendly-fashion-trend/">growing mycelium</a> in small chambers fitted with electrodes, the team linked those chambers to two robots and let the fungus set the tempo for movement.



“By growing mycelium into the electronics of a robot, we were able to allow the biohybrid machine to sense and respond to the environment. In this case we used light as the input, but in the future it will be chemical," explained Rob Shepherd, professor of mechanical and aerospace engineering in Cornell Engineering, and the paper’s senior author. 



<h2 class="wp-block-heading" id="h-melding-mycelium-with-a-robot">Melding mycelium with a robot</h2>



Many biohybrid systems use animal cells such as muscle fibers. Those cells can work in controlled lab setups but demand constant care and strict conditions. 



Mycelia handle rougher settings. They tolerate swings in humidity and temperature, grow on basic nutrients, and respond to many cues. 



That toughness makes them appealing for robots meant to operate outdoors or in messy places where dust, vibration, and weather get in the way.



Mycelia also form <a href="https://www.earth.com/earthpedia-articles/a-beginners-guide-to-mycology/">dense, responsive networks</a>. The electrical activity runs in spikes and patterns rather than steady tones, which is handy for timing movement. That natural rhythm lets engineers detect meaningful signals without decoding every subtle variation.



<h2 class="wp-block-heading" id="h-making-whisper-quiet-signals">Making whisper-quiet signals</h2>



The main hurdle was signal quality. Electrical noise from motors, wires, and the air itself can drown out small biological spikes. The team built a shielded interface that blocks vibrations and electromagnetic interference. 



That design allowed clean recordings while the robots moved, which is rarely possible with living sensors because motion tends to scramble delicate measurements.



Software then monitored the incoming signal in real time. It detected spike times and translated them into control commands. 



The approach focused on rhythm, not on decoding a complex language of signals, which kept the system robust.



<h2 class="wp-block-heading" id="h-robot-gait-from-mycelium-rhythm">Robot gait from mycelium rhythm</h2>



Biology has a term - <a href="https://www.sciencedirect.com/topics/neuroscience/central-pattern-generator" target="_blank" rel="noreferrer noopener">central pattern generator</a> (CPG) - for circuits that produce rhythmic outputs to coordinate movement. The controller here borrowed that idea. The mycelial spikes set a beat. 



The controller mapped that beat to motor timing so the robot could coordinate steps or wheel turns without micromanaging each joint.



Focusing on timing helps avoid overfitting to noisy features. If the rhythm quickened or changed shape under new conditions, the controller shifted the gait accordingly. That kept the loop simple and reliable.

<h2 class="wp-block-heading" id="h-two-robots-one-living-beat">Two robots, one living beat</h2>



To show that it works across designs, the team built a soft, spider-like walker and a small wheeled rover. 



Each held a <a href="https://www.earth.com/news/nasa-plans-use-mushrooms-fungi-mycelium-to-grow-homes-on-mars-the-moon/">living mycelium</a> sample wired to electrodes. When the fungus produced its natural spiking pattern, the robots moved.



The mycelia sensed ultraviolet light. When UV hit the chamber, the spiking pattern changed. The robots then changed how they moved by altering gait timing. 



The researchers also added an override mode through the same interface. They could pause or redirect the robot with an injected signal without damaging the tissue, combining biological autonomy with human supervision.

Soil chemistry changes over hours, days, and seasons, and the cost of sampling across large fields adds up. 



Systems that respond locally to nutrient cues could help apply fertilizer where it’s needed and cut back where it’s not.



"The potential for future robots could be to sense soil chemistry in row crops and decide when to add more fertilizer, for example, perhaps mitigating downstream effects of agriculture like harmful algal blooms," Shepherd expounded.



<a href="https://www.earth.com/news/fungi-can-think-and-make-smart-decisions-without-a-brain/">Environmental monitoring</a> faces similar trade-offs. Sensors fail in wet, dirty, or variable conditions. Mycelia evolved to survive in those conditions and react to them. 



Tapping that sensitivity may give cheap, soft robots a way to notice toxins or pathogens and adjust their paths without hard-coded rules for every scenario.



<h2 class="wp-block-heading" id="h-robotic-mycelium-beyond-light">Robotic mycelium beyond light</h2>



Light is just one input. Mycelia excel as chemical sensors, reacting to nutrients, toxins, and microbial signals. 



Moving from light to chemical cues would open direct links to soil health, pollutant detection, and other real-world triggers. 



A controller can listen for shifts in rhythm as the fungus responds to a molecule and translate that into a change in movement or task.



That shift also aligns with how fields and waterways behave. Chemistry changes in patches and pulses. A living sensor that tracks those changes in place can help robots act locally without heavy computation.



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



Typical robots bolt on their different sensors as if they were simple accessories. This approach blends the sensor into the control loop itself. 



<a href="https://www.earth.com/news/mycocrete-new-material-made-of-fungi-hopes-to-replace-concrete-in-construction-projects/">The living network</a> doesn’t just report data; it shapes timing and action. That’s a different philosophy for machine control.



“This kind of project is not just about controlling a robot. It is also about creating a true connection with the living system. Because once you hear the signal, you also understand what’s going on,” noted lead author Anand Mishra, a research associate in the <a href="https://orl.mae.cornell.edu/" target="_blank" rel="noreferrer noopener">Organic Robotics Lab</a>. 



"Maybe that signal is coming from some kind of stresses. So you’re seeing the physical response, because those signals we can’t visualize, but the robot is making a visualization," Mishra concluded.



There’s still work between lab demos and long-term field deployments. Keeping the biology stable, scaling production, and validating responses across varied environments are real jobs ahead. 



But the key step is now clear: a living network can steer a machine outside a benchtop, and the machine can respond in kind without the setup falling apart.

Scientists attached a mushroom to a 'biohybrid robot body' and the results were amazing

Robots usually take orders from silicon chips and lines of...

Walk into a grocery store today and you may find familiar foods looking less predictable. From corn chips to tofu, climate change is quietly reshaping what fills our plates. Scientists are warning that it is not just about fewer crops, but about harvests becoming wildly unstable.



A global study led by the <a href="https://www.ubc.ca/" target="_blank" rel="noreferrer noopener">University of British Columbia</a> shows that hotter and drier conditions are making food production swing more dramatically. 



These shifts ripple through the economy, driving higher prices, creating financial stress for <a href="https://www.earth.com/news/plants-trade-growth-for-survival-after-drought/">farmers</a>, and leaving vulnerable communities facing hunger.



<h2 class="wp-block-heading" id="h-heat-makes-crops-unstable">Heat makes crops unstable</h2>



The study, published in the journal <a href="https://www.science.org/journal/sciadv" target="_blank" rel="noreferrer noopener">Science Advances</a>, tracked three major crops: corn, soybean and sorghum. 



The researchers found that for every degree of warming, year-to-year yield variability jumps by 7 percent for corn, 19 percent for soybeans and 10 percent for sorghum.



Earlier studies mostly measured declining average yields. This research spotlights something equally dangerous: instability. For many farmers, that instability determines whether they survive another season or face ruin.



“<a href="https://www.earth.com/news/climate-change-will-devastate-global-food-production/">Farmers</a> and the societies they feed don’t live off of averages - they generally live off of what they harvest each year,” said Dr. Jonathan Proctor, assistant professor at UBC and lead author of the study. 



“A big shock in one bad year can mean real hardship, especially in places without sufficient access to crop insurance or food storage.”



<h2 class="wp-block-heading" id="h-rising-disaster-risk">Rising disaster risk</h2>



The numbers highlight how warming multiplies risks. At two degrees hotter than today’s climate, soybean failures that used to occur once a century could strike every 25 years. 



Corn failures would shift from once every hundred years to every 49, while sorghum failures would occur every 54 years.



Unchecked emissions push the timeline further. By 2100, soybean failures could arrive as often as once every eight years. The danger is greatest for farmers in Sub-Saharan Africa, Central America and South Asia, where rain-fed farming and weak financial support leave little room to absorb shocks.



Yet even wealthy regions are not immune. In 2012, a heatwave and drought in the U.S. Midwest cut corn and soybean yields by a fifth, costing billions and triggering a 10 percent spike in global <a href="https://www.earth.com/news/lanthanides-common-metal-in-plant-fertilizer-key-to-boosting-global-crop-food-supplies/">food</a> prices.



<h2 class="wp-block-heading" id="h-heat-and-dryness-worsen-crops">Heat and dryness worsen crops</h2>



The researchers found that it is not just heat alone but its overlap with dry soil that explains these swings. Using global harvest records along with climate data from satellites, models and weather stations, they pinpointed the twin stressors.



“A key driver of these wild swings? A double whammy of heat and dryness, increasingly arriving together,” said Dr. Proctor.



Hot weather dries the soil, which in turn amplifies heat. This vicious cycle hits plants hard, especially during sensitive phases like pollination.



“If you’re hydrated and go for a run your body will sweat to cool down, but if you’re dehydrated you can get heatstroke,” said Dr. Proctor. “The same processes make dry <a href="https://www.earth.com/news/rising-carbon-dioxide-makes-crops-grow-bigger-but-less-nutritious/">farms</a> hotter than wet ones.”



Even short dry spells during high heat can devastate crops, especially soybeans and sorghum, where the overlap of heat and dryness drives much of the volatility.



<h2 class="wp-block-heading" id="h-irrigation-and-its-limits">Irrigation and its limits</h2>



The study shows that irrigation can reduce these risks, but only if water is available. Many of the regions most vulnerable already face water stress or lack infrastructure for large-scale irrigation. 



That means the solution cannot rely on water alone, especially as water demand grows with rising populations, expanding cities, and shifting climate patterns.



In many parts of the world, aquifers are already being depleted faster than they can naturally recharge, adding another layer of uncertainty to future farming. 



Even in wealthier nations, competing demands between agriculture, households, and industry often limit how much water farmers can access during droughts.



<h2 class="wp-block-heading" id="h-addressing-the-root-cause">Addressing the root cause</h2>



The researchers recommend stronger safety nets to help farmers survive difficult years, alongside investment in heat- and drought-resistant crop varieties that can better withstand extreme conditions. 



The experts also highlight the importance of better soil care, such as practices that improve water retention and reduce erosion, and the role of advanced forecasting systems that give farmers more time to prepare for upcoming heatwaves or dry spells.



These steps can soften the blow, but they are not enough on their own. Ultimately, the researchers emphasize that the most reliable and far-reaching solution is cutting the emissions driving global warming. 



Without addressing the root cause, they warn, adaptation measures will always remain partial and temporary.



“Not everyone grows food, but everyone needs to eat,” said Dr. Proctor. “When harvests become more unstable, everyone will feel it.”



The study is published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.ady3575" target="_blank" rel="noreferrer noopener">Science Advances</a>.

Heat is making crop harvests wildly unpredictable

Walk into a grocery store today and you may find...

Coffee is part of the morning routines for millions of people. But does drinking more coffee align with having more muscle? That’s the question behind a new analysis of Americans’ habits and body composition. 



This research doesn’t try to prove cause and effect. It asks whether higher coffee or caffeine intake corresponds to more limb muscle for a given body size.



The answer points in a positive direction for most adults, with an important exception. The details matter, because the way researchers measured muscle and tallied <a href="https://www.earth.com/news/coffee-may-help-you-live-longer-if-you-drink-it-this-way/">coffee intake</a> shapes how to read the results.



<h2 class="wp-block-heading" id="h-why-limb-muscle-matters">Why limb muscle matters</h2>



<a href="https://www.earth.com/news/studies-learn-the-exact-amount-of-time-you-should-spend-training-to-build-muscle/">Muscle mass</a> isn’t just about strength. Lower muscle mass in arms and legs raises the risk of falls, fractures, and everyday struggles that chip away at independence. 



Scientists often track limb muscle adjusted for body size because it flags early losses that can sneak up with age.



A standard yardstick for that job is the appendicular skeletal muscle mass-to-BMI ratio, abbreviated as <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC10401528/" target="_blank" rel="noreferrer noopener">ASMBMI</a>. In plain terms: “How much limb muscle do you have for your body size?” 



This measurement focuses on muscle quantity, not how quickly you rise from a chair or how steady you feel on stairs.



<h2 class="wp-block-heading" id="h-studying-coffee-s-link-to-muscles">Studying coffee's link to muscles</h2>



Researchers pulled data from a large, ongoing U.S. health survey (<a href="https://www.cdc.gov/nchs/nhanes/index.html" target="_blank" rel="noreferrer noopener">NHANES</a>) spanning 2011-2018. 



They started with adults, applied clear rules such as “only include people with full diet interviews and body scans,” and finished with 8,333 participants. Muscle was measured by DXA scans of the arms and legs and then expressed as ASMBMI.



<a href="https://www.earth.com/news/coffee-helps-bacteria-resist-antibiotics-in-your-gut/">Coffee intake</a> came from two 24-hour dietary recalls - structured interviews covering everything people ate and drank on two different days. The team looked at regular coffee, decaf coffee, and total caffeine from all sources. 



Their statistical models adjusted for age, sex, race, education, income, smoking, alcohol, physical activity, BMI, medical conditions, total calories, and protein, so they could compare people who were similar on many fronts except for coffee intake.



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



People who drank more coffee tended to have <a href="https://www.earth.com/news/eating-grapes-every-day-can-transform-your-muscles/">more limb muscle</a> relative to their body size. After full adjustments, the highest coffee group had about a 13% higher ASMBMI than the non-coffee group. 



The highest caffeinated coffee group showed roughly a 12% increase. The top caffeine group showed about an 11% increase. Decaf didn’t show a clear, statistically significant link. 



When researchers drew smoothed trend lines, the pattern appeared approximately linear: more <a href="https://www.earth.com/news/drinking-coffee-may-help-women-stay-sharp-and-strong-as-they-age/">regular coffee</a> or caffeine corresponded to more muscle relative to body size.



There was one major exception. When participants were split by BMI, the positive link disappeared in the group with obesity (BMI ≥ 30). 



In that subset, drinking more coffee was not associated with higher ASMBMI. That doesn’t mean coffee lowers muscle there; it means the helpful pattern seen elsewhere wasn’t present.



A likely reason is biological factors tied to obesity, including chronic, low-grade inflammation that speeds muscle breakdown and may overshadow small benefits from caffeine or other coffee compounds.



<h2 class="wp-block-heading" id="h-limitations-in-this-research">Limitations in this research</h2>



This was a cross-sectional snapshot. It can spot links, but it can’t prove that coffee changes muscle. People with more muscle may simply be more active or keep schedules where coffee fits better. 



The models adjusted for activity and many other variables, which strengthens confidence, but unmeasured factors can still nudge results.



Diet recalls lean on memory and honesty, and add-ins like sugar or cream can be easy to forget. 



ASMBMI captures muscle quantity, not strength or performance, so it can’t tell you how much weight you can move or how good your balance is during daily activities. 



Results also come from U.S. adults in specific survey years, so patterns could differ in other populations.



<h2 class="wp-block-heading" id="h-why-coffee-is-linked-with-muscles">Why coffee is linked with muscles</h2>



Caffeine stimulates the nervous system and modulates how the body uses fuel during activity. Coffee also contains <a href="https://www.chhs.colostate.edu/krnc/monthly-blog/what-are-polyphenols-another-great-reason-to-eat-fruits-and-veggies/" target="_blank" rel="noreferrer noopener">polyphenols</a> with antioxidant and anti-inflammatory properties. 



Lab and animal research suggests these compounds may support healthier muscle by encouraging autophagy - the cell’s cleanup crew for worn-out parts - and by dialing down chronic inflammation over time. 



This analysis didn’t test mechanisms, but these ideas fit with the pattern. Decaf’s “no clear link” signal hints that caffeine may be doing more of the heavy lifting in this dataset.



<h2 class="wp-block-heading" id="h-what-did-we-learn-from-this">What did we learn from this?</h2>



In U.S. adults, higher <a href="https://www.earth.com/news/mood-boost-how-coffee-makes-us-happier-in-the-morning/">regular coffee</a> and total caffeine intake tracked with more limb muscle relative to body size after accounting for many other factors. However, that association did not appear in participants with obesity. 



If coffee already fits your day, these results sit comfortably with a muscle-friendly routine. Keep portions sensible, mind the extras, and avoid late cups that cut into sleep because <a href="https://www.earth.com/news/irregular-sleep-may-cause-premature-muscle-aging/">poor sleep impairs recovery</a>.



If you’re in the obesity range, the study’s “no clear link” finding suggests coffee isn’t a muscle fix. 



The bigger levers are steady resistance training, enough protein spaced through the day, and better sleep, ideally alongside medical care that addresses weight, strength, and metabolic health together. 



Coffee can still be part of that plan if it agrees with you, but it’s not the star of the show.



It’s a pattern, not proof. Pair your coffee with protein, training, and sleep if your goal is to build or protect muscle.

Drinking this every day helps keep muscles tone and strong as you age, preventing frailty

Coffee is part of the morning routines for millions of...

Deforestation in the Brazilian Amazon is doing far more than clearing trees: it’s directly shrinking the region’s rain supply and nudging temperatures upward during the dry season.&nbsp;



A new study led by scientists at the <a href="https://www5.usp.br/english/institutional/" target="_blank" rel="noreferrer noopener">University of São Paulo</a> (USP) is the first to put hard numbers on how much of the recent shift is due to local forest loss versus global climate change.



The researchers found that <a href="https://www.earth.com/news/millions-exposed-to-deadly-heat-from-deforestation/">deforestation</a> accounts for roughly 74.5% of the observed decline in dry-season rainfall and 16.5% of the warming in the biome.



This work arrives just ahead of COP30 in Belém, the Amazonian capital hosting November’s U.N. climate summit - timing that highlights its policy relevance.



<h2 class="wp-block-heading" id="h-amazon-dry-season-and-deforestation">Amazon dry season and deforestation </h2>



The team used parametric statistical models to disentangle overlapping influences - forest loss, temperature trends, precipitation shifts, and greenhouse gas concentrations - on the <a href="https://www.earth.com/news/climate-change-is-disrupting-how-amazon-trees-process-sunlight/">Amazon’s climate</a>.&nbsp;



On average across the biome, dry-season rainfall has fallen by about 21 millimeters per year, with 15.8 mm of that drop traced to deforestation alone. Meanwhile, maximum temperatures have climbed about 2.0°C, and the researchers attribute 16.5% of that rise to forest clearing, with the remainder tied to global warming.



“Several scientific articles on the Amazon have already shown that the temperature is higher, that rainfall has decreased, and that the dry season has increased,” said study senior author Luiz Augusto Toledo Machado of USP.



"There was still no separation between the effect of climate change, caused mainly by <a href="https://www.earth.com/news/cutting-super-pollutants-could-quickly-cool-the-planet/">pollution</a> from countries in the Northern Hemisphere, and deforestation caused by Brazil itself. Through this study, we were able to separate and weigh each of these components, practically showing a kind of ‘account payable.’”



<h2 class="wp-block-heading" id="h-intense-changes-from-forest-loss">Intense changes from forest loss</h2>



One practical insight leaps off the page: the biggest local climate swings happen at the earliest stages of forest loss. The models show the most intense changes in rainfall and temperature occur when 10% to 40% of the forest is removed.&nbsp;



“The effects of the changes, especially in temperature and precipitation, are much more significant in the first few percent of deforestation,” said co-author Marco Aurélio Franco from USP’s Institute of Astronomy, Geophysics, and Atmospheric Sciences.&nbsp;



“In other words, we have to preserve the forest; that’s very clear. We can’t transform it into something else, such as pastureland. If there’s any type of exploitation, it needs to be sustainable.”



That finding reframes “small” incursions: early clearing is not a harmless nibble - it’s when the local water and heat balance is most sensitive.



<h2 class="wp-block-heading" id="h-a-forest-that-makes-its-own-rain">A forest that makes its own rain</h2>



The Amazon is more than a carbon storehouse; it manufactures its own moisture. Through deep roots and vast leaf area, trees pump water skyward, feeding the “flying rivers” - atmospheric flows that deliver rainfall to the Amazon itself and to far-flung biomes such as the Cerrado.



Recent research by some of the same USP scientists illuminated the biome’s rain-making chemistry: <a href="https://www.earth.com/news/household-sprays-release-dangerous-nanoparticles-that-linger-in-the-home/">aerosol nanoparticles</a>, electrical discharges, and day-night reactions act like a cloud-building “machine.” 



Strip away trees, and you weaken that system - less evapotranspiration, fewer cloud seeds, and a longer, harsher dry season primed for fire.



Those dynamics are not abstract. MapBiomas data show the Brazilian Amazon lost 14% of its native vegetation between 1985 and 2023. An area of 553,000 square kilometers, roughly the size of France, was primarily lost to pasture. 



Deforestation dropped to its second-lowest level between August 2024 and July 2025 (4,495 km²). However, degradation - especially from fire - remains stubborn and widespread.



<h2 class="wp-block-heading" id="h-effects-of-amazon-deforestation">Effects of Amazon deforestation </h2>



To parse the drivers, the team combined long-term reanalysis, remote sensing, and land-use classifications (including MapBiomas) with parametric surface equations that track annual cycles and forest loss. Alongside rain and temperature, they examined greenhouse gases.&nbsp;



Across the past 35 years, CO₂ rose by about 87 ppm and methane by about 167 ppb in the region - increases driven more than 99% by global emissions. That result doesn’t contradict studies showing deforestation weakens the forest’s CO₂ uptake.&nbsp;



As Machado noted, flux measurements are local, while concentrations reflect the global burden. In other words, global emissions dominate the background rise, even as local clearing erodes the forest’s ability to absorb <a href="https://www.earth.com/news/dry-spells-weaken-the-amazons-ability-to-store-carbon/">carbon</a>.



<h2 class="wp-block-heading" id="h-keep-the-forest-keep-the-rain">Keep the forest, keep the rain</h2>



Project the trends forward and the message is unambiguous. If clearing continues, the experts warn, dry-season rainfall will decline further and temperatures will climb higher, amplifying drought risk and fire weather.&nbsp;



Other recent work already points to deforestation-driven disruptions of the South American <a href="https://www.earth.com/news/the-atmosphere-has-a-memory-that-affects-the-timing-of-monsoons/">monsoon</a>, which waters central and southeastern Brazil. Weakening that summer lifeline doesn’t just stress farms and cities downstream; it also undercuts the Amazon’s own resilience - making it harder for the forest to recover from shocks like the 2023–2024 droughts.



The new attribution numbers give decision-makers a sharper tool. They quantify how much of today’s dry-season pain is homegrown versus imported via global warming. 



That “account payable” puts a premium on preserving standing forest, restoring degraded areas, and reining in fire - actions that can deliver near-term benefits for rainfall and heat, even as the world tackles emissions.



With COP30 convening in Belém, the study’s take-home is as practical as it is urgent: keep the forest intact, and you keep the rain. Every hectare left standing pays climate dividends - locally, season by season, not just in abstract global carbon ledgers.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-025-63156-0" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Deforestation is drying the Amazon more than climate change

Deforestation in the Brazilian Amazon is doing far more than...

Romans loved garum, a salty fish sauce that showed up on tables from Spain to Syria. A new study spells out which fish actually went into it by reading DNA from tiny bones buried in an ancient salting vat.  



The team worked at Adro Vello, a Roman era fish processing site on Spain’s northwest coast. 



They pulled fragments from the bottom of a vat and extracted <a href="https://www.sciencedirect.com/topics/neuroscience/ancient-dna" target="_blank" rel="noreferrer noopener">ancient DNA</a>, which is genetic material preserved in old remains, to identify the species and peek at past fish populations.  



<a href="https://www.ciimar.up.pt/members/paula-campos/" target="_blank" rel="noreferrer noopener">Paula F. Campos</a>, CIIMAR at the University of Porto, is the corresponding author who helped lead the genetic work.



<h2 class="wp-block-heading" id="h-romans-and-their-sauces">Romans and their sauces</h2>



Roman cooks made <a href="https://fermentology.pubpub.org/pub/h0khkmbv/release/1" target="_blank" rel="noreferrer noopener">fish sauces</a> and pastes in large stone vats along the Atlantic and Mediterranean coasts. 



Workers salted, crushed, and left small fish under controlled fermentation, which broke down tissues and created a savory liquid that seasoned everything from vegetables to meat.  



That process destroyed the usual features scientists use to tell one fish from another. 



Bones were shattered, and acids from fermentation damaged the DNA inside them, which makes species identification tough without genetics.  



Even so, the Adro Vello bones held enough information to test a clear question. Did <a href="https://www.earth.com/news/mass-grave-vienna-discovery-tells-the-story-of-a-forgotten-defeat-by-the-roman-empire/">Romans</a> really pack these vats with sardines, as some earlier visual identifications hinted.&nbsp;&nbsp;



<h2 class="wp-block-heading" id="h-reading-the-recipe">Reading the recipe</h2>



Researchers sampled the residue at the bottom of a single vat and cleaned the tiny vertebrae and scales. They then built DNA libraries and compared overlapping sequences against the reference genome of European sardine.&nbsp;&nbsp;



From those fragments, they assembled the full <a href="https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/mitochondrial-genome" target="_blank" rel="noreferrer noopener">mitochondrial genome</a> of multiple fish, which is a small circular chromosome inside the cell’s energy factories that helps track maternal lineages. Depth of coverage varied across samples, but it was sufficient to confirm identity.&nbsp;&nbsp;



They also used <a href="https://news.uchicago.edu/explainer/what-is-carbon-14-dating" target="_blank" rel="noreferrer noopener">radiocarbon dating</a>, a technique that estimates age by measuring the decay of carbon isotopes, to anchor the material to the early third century AD. That timeline lines up with the period when this coastal factory was active.&nbsp;&nbsp;



<h2 class="wp-block-heading" id="h-dna-found-in-the-roman-sauce">DNA found in the Roman sauce</h2>



The sauce makers at Adro Vello were using European sardine. Genetic signatures placed the ancient fish with present day sardines from the central Atlantic Iberian region, which signals continuity across nearly two thousand years.&nbsp;&nbsp;



Population analyses showed less admixture, meaning less mixing between distant sardine groups, than we see in many modern samples. 



That result hints at lower connectivity among stocks in <a href="https://www.earth.com/news/ancient-roman-concrete-offers-lessons-for-sustainable-building/">Roman</a> times, likely due to different fishing pressure and maritime movement.  



These insights do more than satisfy culinary curiosity. They add data points for how human activity and environment shape marine populations over long periods.&nbsp;&nbsp;



<h2 class="wp-block-heading" id="h-how-dna-survives-fermentation">How DNA survives fermentation</h2>



“In this study, we demonstrate that usable DNA can survive in fermentation environments, such as the brines used by the Romans to make garum,” concluded Dr. Campos.



That is not a trivial point, since acids and microbial enzymes can chop DNA into pieces too small to read. 



The team still recovered enough high quality sequences to assemble full mitochondrial genomes and validate species calls with phylogenetic tests. 



They also reported calendar dates consistent with the site’s archaeological layers. Those dates, along with clean damage patterns typical of truly ancient molecules, strengthen the case that the DNA is original to the vat and not modern contamination.&nbsp;



<h2 class="wp-block-heading" id="h-why-roman-sauce-matters">Why Roman sauce matters</h2>



Foodways reveal trade, labor, and taste. Because garum production plants ringed the coasts, matching species to specific factories helps map supply chains and regional preferences across the empire.



Knowing that Adro Vello used sardines fits finds from other Atlantic facilities. It suggests local fleets targeted schooling fish that could be processed quickly into sauces and pastes for shipment.&nbsp;



Linking ancient and modern sardine genomes also provides a baseline for long term change. 



Fisheries managers can compare today’s gene flow and stock structure with a historical snapshot that predates industrial fleets.  



<h2 class="wp-block-heading" id="h-from-roman-vats-to-present-management">From Roman vats to present management</h2>



Iberian sardines remain central to coastal economies, and managers in Portugal and Spain use a multi-year <a href="https://www.dgrm.pt/documents/20143/46478/PGSARDINHA2021-2026.pdf/d36a1df9-7353-32a4-a06e-c72852e73cb0" target="_blank" rel="noreferrer noopener">plan</a> to set cautious catch limits and seasonal closures. 



Those measures follow scientific advice and aim to stabilize biomass through variable recruitment years. 



Ancient data will not decide quotas, but it can refine assumptions about how populations connect and change. When models rest on sound baselines, policies stand on firmer ground.&nbsp;



The approach used here can travel well beyond Spain. Similar vats exist across the former <a href="https://www.earth.com/news/317-skeletons-from-the-roman-empire-found-beneath-an-old-shopping-center/">Roman</a> world, which means there are many chances to test whether other regions leaned on sardine, anchovy, or mixed catches.



<h2 class="wp-block-heading" id="h-what-comes-next">What comes next</h2>



The authors plan to sample other sites to see how recipes varied from Africa to the western Mediterranean. 



With more genomes in hand, they can test whether regional fleets drew on distinct stocks or tapped a shared pool of fish.

DNA identifies ingredients of the 'ketchup' used on food by the Roman Empire

Romans loved garum, a salty fish sauce that showed up...

We stroll past wheat, clover, and grass and see only the green half of the story. The other half - the roots - do the heavy lifting: anchoring plants, pulling up water and nutrients, and locking away carbon in the soil.



Yet because roots are hidden, scientists have spent decades using muddy, labor-intensive methods to guess their size and spread, often missing the finest, most active threads. According to a team of researchers at <a href="https://international.au.dk/" target="_blank" rel="noreferrer noopener">Aarhus University</a>, that guesswork can finally stop.



<h2 class="wp-block-heading" id="h-a-high-tech-root-census">A high-tech root census</h2>



“It's a bit like studying marine ecosystems without ever being able to dive,” said senior author Henrik Brinch-Pedersen, a professor in the Department of Agroecology.



Until now, the standard approach was to carve out big blocks of <a href="https://www.earth.com/news/world-soil-day-2024-protecting-our-planets-lifeline/">soil</a>, wash away the dirt, sort and dry what remained, and weigh the roots. It’s slow, destructive, and misses the fine roots that absorb nutrients and release carbon to the soil.



The new approach swaps spades for droplet digital PCR (ddPCR), a <a href="https://www.earth.com/news/hidden-chapter-in-human-evolution-revealed-through-genetics/">DNA</a> technology that partitions a teaspoon of soil into tens of thousands of microscopic droplets. Each droplet then answers a yes/no question: Does it contain plant DNA with a specific genetic signature?



The team uses a marker called ITS2 - think of it as a barcode that differs among species - so a single run can reveal not just that roots are present, but whose roots they are. Crucially, it also shows how much underground biomass each species contributes.



“It’s a bit like giving the soil a DNA test,” Brinch-Pedersen said. “We can suddenly see the hidden distribution of species and biomass without digging up the whole field.”



<h2 class="wp-block-heading" id="h-mapping-roots-with-precision">Mapping roots with precision</h2>



Because ddPCR counts DNA molecules across thousands of droplets, it can quantify roots that would otherwise be pulverized or rinsed away. 



That makes it possible to map root communities at high resolution in living fields, pastures, and mixed-species grasslands and to repeat measurements over time without disturbing the site.



The payoff spans several fronts. For climate research, it lets scientists measure how much <a href="https://www.earth.com/news/planting-diverse-crops-traps-carbon-and-boosts-soil-health/">carbon</a> different crops actually push belowground - data that’s been frustratingly hard to pin down but is essential for credible climate accounting in agriculture.



For plant breeding, the digital DNA method creates a path to select varieties that invest more in roots without sacrificing grain or forage aboveground.



And for biodiversity science, the technology finally illuminates the underground dynamics in species mixes - who’s competing, who’s complementing - insights that were “almost impossible before,” Brinch-Pedersen noted.



<h2 class="wp-block-heading" id="h-roots-matter-for-the-climate">Roots matter for the climate</h2>



We tend to picture wind turbines and EVs when we think of climate solutions, but roots are a vast, quiet carbon pump. 



As plants photosynthesize, some of the captured carbon flows belowground into roots and the surrounding soil. Depending on the crop, soil type, and management, a fraction of that carbon can persist for decades or even centuries.



Farmers and policymakers talk about “soil carbon sequestration,” but without precise measurement tools it’s been hard to document gains in ways that stand up to scrutiny. A rapid, species-resolved root assay changes that equation.



<h2 class="wp-block-heading" id="h-dna-test-in-soil">DNA test in soil</h2>



In practice, researchers collect small soil cores, extract DNA, and run ddPCR with species-specific probes keyed to the ITS2 barcode. The number of positive droplets scales with <a href="https://www.earth.com/news/deep-rooted-crops-can-significantly-improve-soil-carbon-storage/">root biomass</a> for that species in that sample. 



Because the test targets DNA directly in soil, it captures fine roots and root fragments as well as thicker roots that are tough to wash and weigh.



There are, however, limits. Close relatives can be tricky to tell apart when their barcodes are nearly identical - ryegrass and Italian ryegrass hybrids, for instance, can blur the signal. 



And the method recognizes only what it’s trained to find. Researchers must validate a probe for each species, so expanding the “DNA library” is both the hurdle and the goal.



“For us, the most important thing is that we have shown it can be done,” Brinch-Pedersen said. “Our vision is to expand the library so we can measure many more species directly in soil samples.”



<h2 class="wp-block-heading" id="h-rapid-answers-from-soil">Rapid answers from soil</h2>



Speed is the other advantage. Traditional root studies hinge on days to weeks of field and lab work per site. The ddPCR method turns around results in hours, making it practical to scale from a few experimental plots to entire farms, seasons, and regions.



That opens the door to experiments that were previously unrealistic. Researchers can compare cover crops for their belowground carbon contributions across soil types. 



They can track how drought shifts root allocation among species in a pasture. They can also screen hundreds of breeding lines for deeper, denser root systems.



<h2 class="wp-block-heading" id="h-plants-that-work-smarter">Plants that work smarter</h2>



Brinch-Pedersen sees a straight line from measurement to design. If breeders can quantify underground investment as easily as they count kernels or measure protein, they can begin to select for <a href="https://www.earth.com/news/tree-crops-a-path-to-feeding-the-world-and-saving-the-planet/">crops</a> that are not only high-yielding but also high-sequestering. These are plants that do more of the climate work for us.



The same logic applies to mixtures. With species-level root data, agronomists can compose plant communities that pack more carbon belowground while maintaining forage or grain output above.



The bigger picture is simple: half a plant lives out of sight, and that half shapes soil health, farm resilience, and the climate. With a “DNA test for dirt,” researchers can finally watch that hidden half at work - no shovels required.



The study is published in the journal <a href="https://academic.oup.com/plphys/article/198/3/kiaf276/8173641?login=false" target="_blank" rel="noreferrer noopener">Plant Physiology</a>.

Digging into plant roots with DNA - no shovels required

We stroll past wheat, clover, and grass and see only...

When plants face a drought, they stop growing. That part isn’t surprising - no water means no business as usual. But what happens when the rain finally returns? You might expect plants to bounce back and grow rapidly to make up for lost time. That’s not what actually happens.



Instead, new research shows plants go into defense mode. Their priority isn’t growing - it’s fighting off threats.



<h2 class="wp-block-heading" id="h-plants-hit-pause-to-survive">Plants hit pause to survive </h2>



A tiny plant known as Arabidopsis thaliana helped scientists understand this. Researchers have long experimented with this plant in labs because it is easy to cultivate and has a simple genetic makeup. It also shares many genes with common crops such as <a href="https://www.earth.com/news/gene-edited-wheat-turns-soil-microbes-into-fertilizer/">wheat</a>, rice, and tomatoes.



When water is scarce, Arabidopsis closes its pores, slows down its activity, and conserves resources.



When water returns, those pores reopen, allowing the plant to rehydrate quickly. But this also welcomes disease-spreading bacteria, fungi, and viruses. Rather than going straight into growth, the plant prepares to protect itself..



<h2 class="wp-block-heading" id="h-genes-tracked-cell-by-cell">Genes tracked cell by cell</h2>



Scientists at the <a href="https://www.salk.edu/" target="_blank" rel="noreferrer noopener">Salk Institute</a> used cutting-edge technology to monitor what happens inside the plant immediately after rehydration.



They focused on how gene activity varies from cell to cell, not just across the whole plant. This kind of research once required grinding up plant tissue and averaging the data, which concealed many details.



Using single-cell and spatial transcriptomics, the team zoomed in on individual cells to see how they responded the moment water returned.



<h2 class="wp-block-heading" id="h-plants-activate-hidden-defenses">Plants activate hidden defenses</h2>



Just 15 minutes after watering the dried-out plants, something big happened. Genes across the leaves started turning on - thousands of them. 



This sudden burst of gene activity wasn’t random. It formed a clear pattern of immune defense. The team calls this “Drought Recovery-Induced Immunity” (DRII).



This rapid and targeted immune response is triggered as soon as rehydration occurs, helping the plant fight off infections while it is still vulnerable. 



“What’s really incredible here,” said Natanella Illouz-Eliaz, first author of the study, “is we would have entirely missed this discovery had we not decided to capture data at these early time points.”



<h2 class="wp-block-heading" id="h-crops-share-drought-defenses">Crops share drought defenses</h2>



After spotting DRII in Arabidopsis, the team checked if it happened in <a href="https://www.earth.com/news/scientists-find-a-surprising-case-of-reverse-evolution-in-wild-tomatoes/">tomatoes</a> too - both wild and farmed. It did. Both types activated the same kind of immune response after drought.



That means DRII probably isn’t just a lab-only thing. It could be common in many crops, especially ones closely related to tomatoes or Arabidopsis. And if that’s true, understanding how DRII works might help us grow tougher crops in the future.



“Drought poses a major challenge for plants, but what is less understood is how they recover once water returns,” said senior author Joseph Ecker. “We found that, rather than accelerating growth to compensate for lost time, Arabidopsis rapidly activates a coordinated immune response.”



<h2 class="wp-block-heading" id="h-unanswered-genetic-puzzles">Unanswered genetic puzzles</h2>



The speed of the immune response was striking. Within minutes of rehydration, leaves were already activating defense genes. 



That raises some big questions for scientists. How does a signal from the <a href="https://www.earth.com/news/plant-roots-could-be-key-to-fighting-climate-change/">roots</a> reach the leaves so quickly? What is the signal?



Experts also want to figure out how DRII might be used in real-world farming. Can <a href="https://www.earth.com/news/tree-crops-a-path-to-feeding-the-world-and-saving-the-planet/">crops</a> be bred or engineered to trigger this response more effectively? Could that protect yields during unpredictable weather?



“Our results reveal that drought recovery is not a passive process but a highly dynamic reprogramming of the plant’s immune system,” Ecker said. 



“By defining the early genetic events that occur within minutes of rehydration, we can begin to uncover the molecular signals that coordinate stress recovery and explore how these mechanisms might be harnessed to improve crop resilience.”



<h2 class="wp-block-heading" id="h-stronger-plants-for-dry-times">Stronger plants for dry times</h2>



Droughts are becoming more frequent and more extreme in many parts of the world. Crops that can bounce back strong - and defend themselves when they do - could make a real difference in keeping food supplies steady.



This discovery shows that the moment after water returns may be just as important as the <a href="https://www.earth.com/news/droughts-and-extreme-weather-events-are-escalating/">drought</a> itself. 



The research also demonstrates that plants don’t passively wait to grow again - they make a quick and strategic move to survive. And that’s something we are only beginning to understand.



The full study was published in the journal <a href="https://www.nature.com/articles/s41467-025-63467-2" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Plants trade growth for survival after drought

When plants face a drought, they stop growing. That part...

From space, Earth looks lusher than it did a generation ago. Satellite records show that leaf area has expanded across most of the planet since the early 1980s - a phenomenon popularly called “global greening.” 



It sounds like unambiguously good news: more foliage to soak up carbon, more habitat, more shade. But a new analysis throws a bucket of cold water on such an optimistic view.



In many places, greener landscapes have gone hand in hand with <a href="https://www.earth.com/news/40-percent-of-earths-land-has-became-permanently-drier/">drier soils</a>, especially where water is already scarce. The paradox is simple: plants that flourish also tend to drink more.



<h2 class="wp-block-heading" id="h-four-decades-of-data">Four decades of data</h2>



The research team stitched together four decades of evidence - multiple satellite records of vegetation, modern climate datasets, and simulations from a dozen Earth system models.



They used these to tease out cause and effect between <a href="https://www.earth.com/news/scientists-finally-learn-what-makes-plants-roots-grow-faster-and-stronger-autophagy/">plant growth</a> and soil moisture.



Looking from 1982 through the end of this century, they asked a straightforward question with big consequences: what usually happens to the water held in the ground when vegetation ramps up?



<h2 class="wp-block-heading" id="h-greener-landscapes-more-water">Greener landscapes, more water</h2>



Their answer is sobering. About two-thirds of the world’s vegetated land has greened since the early 1980s, but nearly half of those greener areas have also dried out below the surface.



That “greening–drying” pattern shows up most clearly in Central Africa, Central Asia, eastern Australia, and swaths of mid- to high-latitude Europe - places where rainfall is fickle and heatwaves are becoming more punishing.



There are brighter spots. Parts of North America, the Indian Peninsula, and the southern Sahel buck the trend, showing “greening–wetting,” where extra leaves coexist with moister soils. But the overarching story is that more vegetation often means a thirstier landscape.



<h2 class="wp-block-heading" id="h-lush-growth-dries-the-land">Lush growth dries the land</h2>



Why would that be? Plants are living pumps. To photosynthesize, they open microscopic pores on their leaves to draw in carbon dioxide. 



Water escapes through those same pores, a process called transpiration. Add more leaves or extend the growing season and you boost the total draw on the local water budget.



In wet climates with regular recharge, the added demand can be balanced by <a href="https://www.earth.com/news/rainfall-is-increasingly-unpredictable-due-to-climate-change/">rainfall</a> and snowmelt. In drylands, or in places where warm-season rains have weakened, the balance tips the other way. Soil moisture is the first line of credit, and it gets depleted.



Rising CO2, land management, and warming have boosted global leaf area, lengthening growing seasons and adding vegetation worldwide. Trees can shade and save soil moisture, but in water-limited regions, added transpiration often outweighs those benefits.



The atmosphere’s rising “thirst” under warming - meteorologists call it higher vapor pressure deficit - adds yet another straw to the same glass. When the air can hold more moisture, it pulls harder on leaves and soils alike.



<h2 class="wp-block-heading" id="h-losing-earth-s-natural-water-buffer">Losing Earth’s natural water buffer</h2>



The consequences ripple well beyond a wilting lawn. <a href="https://www.earth.com/news/how-soil-moisture-can-predict-severe-storms/">Soil moisture</a> is the quiet buffer that keeps crops from failing between rains, feeds streams weeks after a storm, and tamps down wildfire risk.



As that buffer shrinks, irrigation demand rises, late-season flows dwindle, and heat extremes become more dangerous because dry soils can no longer shed heat through evaporation.



Ecologically, greener-but-drier can rearrange communities. Woody encroachment in savannas may squeeze out grasses that grazers need. In northern forests, faster spring growth may be offset by late-summer stress that leaves trees susceptible to pests and fire.



<h2 class="wp-block-heading" id="h-a-climate-fix-with-tradeoffs">A climate fix with tradeoffs</h2>



It’s tempting to read <a href="https://www.earth.com/news/2020-was-earths-greenest-year-in-two-decades/">greening</a> as a climate solution in its own right. And in many contexts - protecting existing forests, restoring wetlands, planting the right trees in the right places - nature is absolutely part of the answer.



What this study adds is nuance: greening is not automatically good for water. In cities, for example, more urban canopy cools streets and cleans the air, but it also increases transpiration. If the species mix is ill-suited to local rainfall, or irrigation relies on potable water, the fix can create its own strain.



On farms, hedgerows and windbreaks can improve microclimates and reduce evaporation from bare soil. Yet high-water-use species planted at large scale in arid basins may cut into already stretched rivers.



<h2 class="wp-block-heading" id="h-future-feedbacks-between-plants-and-water">Future feedbacks between plants and water</h2>



The authors didn’t stop at the past. Using the same blend of observations and models, they projected how vegetation–water feedbacks may evolve through 2100.



In many regions, especially under hotter scenarios, soils become more sensitive to changes in plant activity: a given boost in leafiness more readily drains the root zone. 



Where precipitation is expected to increase substantially, that added income can balance the books. Where it isn’t, the greening–drying paradox tightens its grip.



<h2 class="wp-block-heading" id="h-smarter-restoration-strategies">Smarter restoration strategies </h2>



None of this argues against restoration or <a href="https://www.earth.com/news/planting-too-many-trees-could-spoil-the-planet/">tree planting</a>. It argues for smarter versions of both. A watershed that mixes deep-rooted native species, patches of shade, and open ground can deliver carbon storage, flood mitigation, and cooling without overtaxing local supplies.



Riparian buffers that slow runoff and recharge aquifers do double duty for water and biodiversity. In drylands, species choice matters. Drought-tolerant shrubs and trees with efficient water use can stabilize soils and provide habitat without guzzling what little is available.



Even in humid regions, paying attention to late-summer soil moisture - not just annual rainfall - helps avoid surprises.



<h2 class="wp-block-heading" id="h-global-greening-and-water-security">Global greening and water security </h2>



There’s also a policy undercurrent here. Nature-based solutions are rightly gaining traction in climate plans, but their success will be measured on the ground, not from orbit. 



Accounting for water alongside carbon - evaluating how projects alter soil moisture, streamflow, and downwind climate - should be standard practice.



That means monitoring, course-correcting when plantings are too dense or too thirsty, and designing projects at the scale where water actually moves: the watershed.



The picture from space remains compelling: a greener Earth than our parents knew. The view from the ground is more complicated. Leaves are only half the story. Water is the other half, and in a warming world it’s the half we can least afford to ignore.



The study is published in the journal <a href="https://www.nature.com/articles/s43247-025-02470-3" target="_blank" rel="noreferrer noopener">Communications Earth &amp; Environment</a>.
