What we eat is not just about hunger. Meals carry culture, habits, and values. They shape how we see ourselves and how others see us. 



Our diets also shape the world we live in. Animal agriculture drives climate change, damages ecosystems, and raises questions about health and ethics.



Scientists agree that cutting down on meat and dairy is one of the fastest ways to reduce harm. Yet progress is uneven. 



Men, in particular, resist plant-based eating more than women. Why? A new study offers an answer, pointing to masculinity as a hidden driver of <a href="https://www.earth.com/news/low-carb-or-low-fat-food-quality-is-more-important-for-heart-health/">food choices</a>.



<h2 class="wp-block-heading" id="h-why-men-resist-dietary-change">Why men resist dietary change</h2>



The research was conducted by teams at the University of Bath, Bryant Research, and the <a href="https://www.uzh.ch/en.html" target="_blank" rel="noreferrer noopener">University of Zurich</a>. 



The team examined links between gender norms and food. The researchers asked a tough question: how can plant-based diets be marketed to men without clashing with their sense of identity?



“Animal agriculture is key culprit of environmental degradation, public health risks, and animal suffering. Reducing meat and animal product <a href="https://www.earth.com/news/scientists-identify-two-key-habits-for-losing-weight-without-dieting-meal-timing/">consumption</a> is widely recognized as an effective way to mitigate these harms," said Dr Annayah Prosser of the <a href="https://www.bath.ac.uk" target="_blank" rel="noreferrer noopener">University of Bath</a> School of Management.



"However, men continue to consume more meat than women, are less likely to be vegetarian or vegan, and are more resistant to initiatives that promote reductions in meat consumption.” 



<h2 class="wp-block-heading" id="h-masculinity-at-the-table">Masculinity at the table</h2>



The study surveyed over 1,000 men in the UK. The results showed a clear trend: the more men embraced traditional masculine traits, the more meat they ate.



This wasn’t only about taste. Men attached meaning to meat. For many, meat stood for strength, self-reliance, and even cultural pride. Vegetarianism, on the other hand, looked like a threat.



<h2 class="wp-block-heading" id="h-traits-shaping-men-s-diet">Traits shaping men’s diet</h2>



The researchers measured six traits: avoidance of femininity, emotional restraint, aggression, achievement status, self-reliance, and attitudes toward sex. Not all carried the same weight. Two stood out as the biggest predictors of high meat <a href="https://www.earth.com/news/popular-diet-restricting-calories-can-lead-to-mood-emotional-slumps-especially-in-men/">consumption</a>.



“Beyond the well-known link between masculinity and meat, our study identified two masculine norms that may drive this connection: ‘avoidance of femininity’ and ‘achievement status,'" said study lead author Elise Hankins of <a href="https://bryantresearch.co.uk" target="_blank" rel="noreferrer noopener">Bryant Research</a>.



"Men endorsing these specific norms tended to eat more meat, were more attached to meat and dairy, viewed vegetarianism as a threat to British culture and found meat more masculine."



Hsnkins said that in order to shift men’s diets, the challenge is to address these norms and find ways to work with - not against - men’s identities.



<h2 class="wp-block-heading" id="h-men-s-contradictory-diet-views">Men’s contradictory diet views</h2>



Surveys showed numbers, but conversations told a more complicated story. In online focus groups, men often contradicted themselves.



 Many men insisted gender had nothing to do with their food choices. Minutes later, they described how friends, families, or peers influenced what ended up on their plates.



“Men in our focus groups were conflicted over the role masculinity played in their meat consumption. At first, many men wholly dismissed the role their gender had over their diet, but minutes later they would speak about the vast influences their social network and male peer group had on their menu choices,” said Dr Prosser.



“Researchers understand that eating is a fundamentally social activity, and our research shows that while men may not wish to recognise it overtly, masculinity has a major covert influence on dietary choices.”



<h2 class="wp-block-heading" id="h-the-problem-of-taste">The problem of taste</h2>



One issue kept coming up: flavor. Men doubted whether plant-based foods could match meat for taste. Many assumed alternatives were bland or unsatisfying.



The researchers argue that changing this perception is vital. If plant-based meals feel indulgent and rich, resistance will fade. Campaigns that spotlight flavor, cooking methods, and satisfaction could make a difference.



<a href="https://www.earth.com/news/healthier-diet-could-boost-memory-delay-dementia/">Nutrition</a> also matters. The study showed that men respond strongly to arguments about health, protein, and physical performance.



Marketing that shows plant-based eating as fuel for strength and longevity may resonate more than environmental appeals alone. Fitness-focused stories could make men view plant-based diets as tools for improvement, not sacrifices.



<h2 class="wp-block-heading" id="h-messaging-that-works">Messaging that works</h2>



The researchers warn against directly labeling plant-based foods as “manly.” This tactic risks rejection. Subtler connections to performance, adventure, or resilience could work better.



Packaging and labeling also need care. Familiar words like “meaty” can reassure consumers while helping them see these foods as genuine replacements, not poor imitations.



Food choices don’t happen in isolation. Friends, partners, and families play huge roles. Campaigns that work within these networks might succeed where individual-focused messages fail. 



Price is another barrier. Many men feel plant-based products cost too much. Policies that reduce prices or offer incentives could make plant-based meals more competitive with meat and dairy.



<h2 class="wp-block-heading" id="h-culture-shaping-men-s-diet">Culture shaping men’s diet</h2>



The findings show that resistance to plant-based diets isn’t just about food. It’s about identity, culture, and belonging. 



Men’s connection to meat often hides beneath layers of social influence and masculine ideals. To change diets, campaigns must work with these realities, not ignore them.



This study reminds us that the road to sustainability is cultural as much as scientific. Changing habits requires more than statistics on climate or health. It requires understanding the values people attach to what they eat. Only then can a shift toward greener diets gain real momentum.



The study is published in the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0272494425001768?via%3Dihub" target="_blank" rel="noreferrer noopener">Journal of Environmental Psychology</a>.

Men face a masculinity barrier to greener diets

What we eat is not just about hunger. Meals carry culture, habits, and values. They shape how we see ourselves and how others see us. Our diets also shape the world we live in. Animal agriculture drives climate change, damages ecosystems, and raises questions about health and ethics.

Mindfulness helps athletes perform better in competition. When you think of sports, it’s often the physical component that seems to be the most challenging. But many athletes and coaches understand that there is a mental component as well, and that being prepared for competition psychologically is often just as important as being prepared physically.

“It’s been suggested that many coaches regard sport as at least 50 percent mental when competing against opponents of similar ability. In some sports, that percentage can be as high as 80 to 90 percent mental,” says Keith Kaufman, a sport psychology practitioner and research associate at <a href="https://www.catholic.edu/index.html">The Catholic University of America.</a>

There are a number of studies that support the importance of psychological preparation in sports.

 One such study looked at over 200 Canadian athletes from the 1984 Olympics who were assessed for three readiness factors: mental, physical, and technical. The results showed that out of these three factors, only mental readiness had significant impact on these athletes’ success in the Olympics.

“With popular belief and scientific evidence being in such harmony, one might expect that mental training would be a top priority within the athletic community. However, curiously, this is not the case,” explains Kaufman. “We have met so many athletes and coaches who know that mental factors, such as concentrating, relaxing and letting go of thoughts and feelings, can aid performance, but have no idea how to actually do those things under the pressures of training and competition.”

While presenting his research at the 125th Annual Convention of the <a href="http://www.apa.org/">American Psychological Association</a>, Kaufman outlined a multi-step program he and his team had developed for practicing mindfulness and preparing mentally.

In short, mindfulness involves being aware of the present moment and accepting things as they are. When athletes are able to do this, they are able to better focus on their performance rather than being distracted or having <a href="https://www.earth.com/news/marijuana-low-doses-relieve-stress/">anxiety</a>. 

“For example, an athlete could identify that ‘right now, I’m having the thought that I can’t finish this race,’ so rather than reflecting an objective truth, it’s seen as just a thought,” says Kaufman.

His program involves mindfulness practice, sport-specific meditation, and other formal exercises. Overall, it works to help athletes incorporate mindfulness into their everyday life as well as workouts, practices, and competition. 

This approach has already shown great results in practice. Two studies of 81 university athletes found that individuals who completed Kaufman’s program exhibited significant increases in the arenas of mindfulness and “flow,” which is defined as the mental construct associated with being “in the zone.”

Athletes also rated their own performance higher and experienced less anxiety while competing. These increases were also maintained in follow-up months later. In fact, two teams that had previously had losing records the year before both had winning seasons after completing the program.

Kaufman also states that this program could benefit people in performing arts or business, not just athletes. So if you find that you’re experience performance-related anxiety, it might be a good idea to practice some mindfulness.

Beauty is pain, isn’t that what they say? And as any woman who has hobbled home after a long day in heels will tell you, the pain is very real. But according to a new study, both women and men prefer individuals who wear heels, and men are twice as likely to give attention or offer help to a woman who is wearing heels. 

Surveys have also shown that women find that wearing heels can boost <a href="https://www.earth.com/news/people-consider-intuitive/">confidence</a> because they make one feel more attractive. 

But the decision to wear heels forces one to forgo comfort and practicality, and risk many different injuries from back pain to broken ankles. 

Researchers at <a href="https://www.abdn.ac.uk/">Aberdeen University</a> published a study that looked at high heels and their high-risk factor and discussed this unspoken societal expectation. 

“There is pressure on women to wear heels, and celebrity influence with people such as Victoria Beckham and Kate Middleton making it fashionable to do so, whether they intend to or not,” said Dr. Max Barnish, lead author of the study.

The facts prove that heels can be quite detrimental to a person’s health, as they can cause back pain, ankle problems, and an increased risk of falling. 

Studies performed on the impact the high heel has on the foot over time and they all point to differences between women who wear high heels regularly to women who wear flats. Choosing not to wear high heels could also strengthen the ankle and prevent further injury. 

Science is by no means demanding a boycott of one of the most popular shoe styles. But workplace dress codes and government mandates could focus more attention on making the heel optional, leaving the decision up to the individual.

Inflammatory bowel diseases like Crohn’s Disease and Ulcerative Colitis are diseases that affect the lining of your intestinal tract and colon. Inflammation of these areas of the body can result in diarrhea, ulcers, and can be severely painful. But now, a study composed by researchers at the <a href="https://medicine.wustl.edu/">Washington University School of Medicine</a> in St. Louis has resulted in some exciting findings that could potentially alleviate these symptoms and build a tolerance to inflammatory bowel diseases. The solution may be as simple as eating a protein and tryptophan-rich diet. 

Luisa Cervantes-Barragan, a postdoctoral researcher, was studying gut microbiomes and tolerance-promoting immune cells in two groups of mice when she found that one group had these cells and the other group, located far away from the first group, did not. 

This led Cervantes-Barragan to believe that environmental factors played into the appearance of healthy gut bacteria that would build a tolerance to cells causing inflammatory diseases. 

Researchers discovered that there were six different species of bacteria present in the <a href="https://www.earth.com/news/aggression-male-mice/">mice</a> with the tolerance-promoting cells, while the other group had none.

Eventually, Cervantes-Barragan and her team associated tryptophan levels with this immunity and doubled the amount of tryptophan fed to the mice which ended up doubling the number of tolerance promoting cells in the mice’s gut.

“The more tryptophan the mice had in their diet, the more of these immune cells they had,” Said Marco Colonna, MD, and senior author of the study. 

Humans have similar gut bacteria and immune cells which could mean that increasing our tryptophan levels with, say, a protein heavy diet, would produce more tolerant cells and alleviate inflammatory bowel diseases in humans.

The 125th Annual Convention of the <a href="about:blank">American Psychological Association</a> featured presentations of a large number of studies that independently investigated the effects of yoga as a therapy for depression.

“Yoga has become increasingly popular in the West, and many new yoga practitioners cite stress-reduction and other mental health concerns as their primary reason for practicing,” says Lindsey Hopkins, of the <a href="https://www.sanfrancisco.va.gov/">San Francisco Veterans Affairs Medical Center</a> “But the empirical research on yoga lags behind its popularity as a first-line approach to mental health.”

Hopkins chaired the session involving yoga’s effects on depression, and presented her own research based around the acceptability and antidepressant effects of hatha yoga. Hatha is a branch of yoga that puts emphasis on physical exercises matched with meditative and breathing exercises.

Her study called upon 23 male combat veterans who participated in twice-weekly <a href="https://www.earth.com/news/yoga-lower-back-pain-therapy/">yoga</a> classes for two months. The results showed that participants with elevated depression scores prior to the yoga study showed a significant decrease in depression symptoms after the 8-week time period.

Sarah Shallit of <a href="https://www.alliant.edu/">Alliant University</a> in San Francisco ran a similar study, this time investigating the effects of Bikram yoga – a form of heated yoga that is commonly practice in the West – on depression levels in 52 women, ages 25-45. Half of the participants were assigned to participate in twice-weekly classes for eight weeks, while the other half were told to wait and used as controls. Shallit found that after the eight-week session, women who practiced Bikram yoga showed a significant reduction in depression levels compared to the control group.

Another study presented during the session was from researchers at <a href="http://www.massgeneral.org/">Massachusetts General Hospital</a>, who presented data from a pilot study showing how 29 adults responded to the same Bikram yoga program as Shallit’s study. The results showed anti-depressant qualities and improved other secondary measures such as quality of life, optimism, and cognitive and physical functioning. 

Two studies from Nina Vollbehr of the <a href="https://charterforcompassion.org/center-for-integrative-psychiatry-lentis">Center for Integrative Psychiatry</a> in the Netherlands involved analysis of the potential for yoga to influence chronic and treatment-resistant depression. The researchers measured participants’ levels of depression, stress, anxiety, rumination and worry before yoga sessions and then nine weeks after they participated in weekly yoga sessions, and then four months after that. The results showed that depression, anxiety, and stress decreased throughout the program and persisted four months afterwards as well. Rumination and worry didn’t decrease immediately after the yoga sessions, but four months later they decreased as well.

Yoga also had beneficial effects for mildly depressed university students, as Vollbehr studied 74 participants who received 30 minutes of yoga or relaxation and performed the exercise over a period of eight days. Results showed that both yoga and relaxation were equally effective at reducing mild depression immediately after treatment.

“These studies suggest that yoga-based interventions have promise for depressed mood and that they are feasible for patients with chronic, treatment-resistant depression,” says Vollbehr.

These studies highlight a new push in the U.S. for alternative methods of treatment for depression outside of pharmaceuticals. The U.S. military is currently looking into creating its own treatment programs for veterans to help reduce post-combat depression.

Male attitudes toward women often shaped by pornography exposure. In a survey of over 300 undergraduate college males, age 17 to 54 years old, researchers found that the age at which a boy is first exposed to pornography has a direct association with certain sexist attitudes later in life. However, some of the results may surprise you – just as they did the researchers.

Research from the <a href="https://www.unl.edu/">University of Nebraska, Lincoln</a>, presented at the 125th Annual Convention of the <a href="http://www.apa.org/">American Psychological Association</a>, analyzed how the age of exposure to pornography relates to <a href="https://www.earth.com/news/brain-determines-social-dominance/">male</a> conformity to two masculine norms: playboy (defined as sexually promiscuous) and seeking power over women. 

The participants in the study were 85% white and 93% heterosexual. The survey asked about their first exposure to pornography, detailing what age they were and whether the exposure was intentional, accidental, or forced. The second half of the survey asked them to respond to questions designed to measure the two established masculine norms.

Although the results showed no significant association between age of exposure and segmenting to the two masculine norms, it did show a different association for each.

“We found that the younger a man was when he first viewed pornography, the more likely he was to want power over women,” says Alyssa Bischmann, a doctoral student at Nebraska. “The older a man was when he first viewed pornography, the more likely he would want to engage in playboy behavior.”

These findings were surprising to the researchers, who had expected both norms to be higher when age of first exposure was younger.

“The most interesting finding from this study was that older age at first exposure predicted greater adherence to the playboy masculine norms,” explains Chrissy Richardson, also of the <a href="https://www.unl.edu/">University of Nebraska</a>. “That finding has sparked many more questions and potential research ideas because it was so unexpected based on what we know about gender role socialization and media exposure.”

Bischmann believes these findings may be due to variables that weren’t examined in the survey, such as religiosity, sexual performance anxiety, negative sexual experiences, or whether their first exposure to pornography was positive or negative. No association was found between nature of exposure and the two masculine norms.

“We were surprised that the type of exposure did not affect whether someone wanted power over women or to engage in playboy behaviors. We had expected that intentional, accidental or forced experiences would have differing outcomes,” says Bischmann.

The researchers believe these findings may help further understanding of the impact pornography has on heterosexual men, extending to various male social and emotional issues as well as the mistreatment of women. Further research needs to be done before any significant conclusions can be made.

German researchers have discovered an alarming amount of bacteria in used kitchen sponges. DNA samples from 14 sponges contained bacteria with pathogens that can cause infections and serious <a href="https://www.earth.com/news/climate-change-spread-diseases/">diseases</a> in humans. 

Scientists from <a href="http://en.hs-furtwangen.de/">Furtwangen University</a> closely analyzed kitchen sponges and found the presence of 362 different types of bacteria. They detected a small amount of Gammaproteobacteria, which is a class of bacteria that includes pathogens capable of causing the plague, cholera, Salmonella, and typhoid fever.

The researchers used a method called fluorescence in situ hybridization, a process in which fluorescent probes are used to bind to parts of DNA. Confocal laser scanning microscopy made the bacteria in the sponges visible. One sample was found to have 54 billion bacterial cells in an area the size of a single square centimeter. 

“Despite common misconception, it was demonstrated that kitchen environments host more microbes than toilets,” said the authors of the study. 'This was mainly due to the contribution of kitchen sponges, which were proven to represent the biggest reservoirs of active bacteria in the whole house.”

The team pointed out that the porous nature of kitchen sponges combined with their liquid-absorbing capacity make them a perfect storage space for tiny living organisms. 

“Kitchen sponges are likely to collect, incubate and spread bacteria from and back onto kitchen surfaces, from where they might eventually find their way into the human body, e.g. via the human hands or contaminated food,” the researchers said.

The team boiled and microwaved the kitchen sponges in an attempt at sterilization, and found bacteria was only reduced by 60 percent at the most. They also determined that using these particular methods of sterilization may actually increase risk 2 bacteria content. This bacteria contains pathogens associated with less serious illnesses.

While most of the bacteria found in this study was harmless, the authors express a need for further research to determine just how pathogenic the bacteria found in the kitchen sponges actually are. The researchers recommend replacing kitchen sponges every week. 

The study is published in the journal <a href="http://advances.sciencemag.org/">Scientific Advances</a>.

During a time of great <a href="https://www.earth.com/news/trump-decision-paris-climate-agreement/">political tension</a> and discord, a new study reveals how the arts can help counter divisions and bring people together.

A study conducted by psychologists from the <a href="https://www.kent.ac.uk/">University of Kent</a> and the <a href="https://www.lincoln.ac.uk/">University of Lincoln </a>found that engagement in the arts boosted prosociality or an individual's dedication to volunteering and charitable giving. 

Arts engagement was such a strong catalyst for prosociality that the only things found to be more important factors in determining one’s charitable likelihood were average income, age, and education.

The study was led by first author Dr. Julie Van de Vyver at Lincoln University and corresponding author Professor Dominic Abrams at Kent's School of Psychology. The research was published in the journal Social Psychological and Personality Science.

The psychologists used research gathered from a UK survey to look at the correlation between arts engagement and prosociality within a community. Researchers used data specifically from the Economic and Social Research Council’s Understanding Society annual National Longitudinal Survey that covered over 30,000 participants.

The results found that engagement in the arts predicted an individual's charitable tendencies “more strongly than a large set of demographic variables such as gender, individual resources such as personal income, core personality such as openness, and sports engagement.” 

“It was remarkable that regardless of people's age, education, employment and savings, their engagement with the arts remained a stronger predictor of their prosociality than did any other variables,” Dr. Abrams said. 

This research helps to show the necessity of the arts in communities worldwide. Investing in the arts rather than defunding those programs could lead to more economic progress as well as motivate charitable giving and community involvement.

Breathing trouble in pugs and French bulldogs is tough to predict. Pugs, bulldogs, and French bulldogs are some of the most popular breeds of canine. In fact, the bulldog is the national dog of the UK and pug fever places the pug as one of the most popular breeds worldwide. However, these <a href="https://www.earth.com/news/reason-dogs-friendly-love/">dogs</a> all belong to a family of Brachycephalic dogs whose signature traits of small heads and wrinkled faces put them at risk for breathing problems, overheating, and disease.

Scientists from the <a href="https://www.cam.ac.uk/">University of Cambridge</a> performed a study that looked specifically at physical traits of these dog breeds to see if facial characteristics alone could indicate breathing problems later in life. This, in turn, could help breed out those harmful indicators and provide longer, healthier lives for the dogs overall. 

The research team hoped to prove the findings of a 2015 study by researchers at the <a href="http://www.london.ac.uk/rvc.html">Royal Veterinary College, University of London</a>, which concluded that dogs with shorter muzzles were more likely to suffer breathing problems later on in life.

But the Cambridge study found it wasn’t so simple. In fact, the team couldn’t prove conclusively if the 2015 study’s findings were accurate. By just measuring facial features like neck girth, they couldn’t find hard evidence that proved physical features alone could indicate the development of life threatening breathing issues.

“At this moment there is no conclusive way of predicting whether any individual pug or bulldog will develop breathing difficulties, so we are now looking for genetic tests that may help breeders get rid of BOAS more rapidly,” Dr. DAvid Sargan, a joint lead author of the study said. 

The research team did find a degree of consistency when measuring nostril opening as an indicator of BOAS or Brachycephalic Obstructive Airway Syndrome. 

“Breeding for open nostrils is probably the best simple way to improve these breeds. Dog breeders should also avoid using dogs with extremely short muzzles, wide faces, and thick necks. These traits are all associated with increased risk of having BOAS,” Dr. Nai-Chieh Liu, first author of the study, said. 

Studies like this can help improve the overall health and wellness of a dog by showcasing traits to look out for.

Humid heat in South Asia to become deadly this century. With <a href="https://www.earth.com/news/earth-two-degrees-warming/">climate change</a> becoming an increasing reality, certain parts of the world may soon experience conditions that are simply unlivable. In 2015, Pakistan, India, and other parts of South Asia endured the fifth highest recorded heatwave in history and over 3,000 people were killed. 

Scientists predict that by the end of the 21st century, South Asia, which houses one fifth of the world’s population, will see humidity and high temperatures that will could be fatal. 

A study led by Eun-Soon Im from the <a href="http://www.ust.hk/">Hong Kong University of Science and Technology</a> set out to measure “wet-bulb temperature,” which he defined as “the lowest temperature that air can be cool to be evaporating water.” 

By looking at the wet-bulb temperature and human’s capability of cooling off in response to rising heat and humidity, the research team aimed to predict how changing conditions will affect human life. 

The study revolved around two climate scenarios, one that used climate change projections as is, and one that factored in mitigation efforts that were goals pledged by the UN Conference on Climate Change in 2015. 

The research showed that wet-bulb temperatures are expected to rise to 35 degrees celsius, also known as the survivability threshold, over most of the South Asia and even go over in some parts.

The findings using the mitigation scenario predicted that wet-bulb temperatures would still be dangerously high, but luckily not past the survivability threshold. 

These findings prove the vital necessity of creating new strategies to combat climate change and hopefully prevent deadly temperature spikes like the ones predicted to hit South Asia at the end of the 21st Century.

New inexpensive treatment can quickly remove BPA from water. Bisphenol A, also known as BPA, is a dangerous chemical used in the production of some plastics and epoxy resins. In a breakthrough study, a research team at <a href="http://www.cmu.edu/">Carnegie Mellon University</a> has developed an inexpensive and effective way to remove BPA from water. 

BPA is so widespread that both people and wildlife are commonly exposed to it. Chemist Terrence J. Collins led a team of colleagues in an effort to determine just how much BPA is present in everyday products and water sources. The team also calculated the danger of the chemical. 

The study, published in <a href="http://pubs.rsc.org/en/journals/journal/gc">Green Chemistry</a>, creates a strong argument for the immediate elimination of BPA from water. BPA imitates estrogen and can have a dangerous impact on the body's endocrine system. Previous studies in both animal and human cells have shown that BPA negatively affects brain and nervous system development, growth and metabolism, and reproductivity.

Although BPA-free products such as water bottles and baby bottles began to emerge in 2010, many BPA substitutes are toxic in ways similar to <a href="https://www.earth.com/news/billions-tons-plastic-thrown/">BPA</a>.

"BPA replacements have often not been adequately tested despite the fact that testing is easy to do," said Collins.

Over 15 billion pounds of BPA are still produced every year, so tackling the management and cleanup of BPA is no simple task. 

"There is no escape from BPA -- for any living creature," said Collins. "The massive global use of BPA burdens an already overstrained water treatment infrastructure and most BPA water releases simply never reach a water treatment facility. Our approach has high potential to be a much better remediation strategy for BPA-contaminated waste streams."

The researchers created a system which involves a group of catalysts called TAML activators. These small molecules, which imitate oxidizing enzymes, can very effectively break down harmful chemicals in water when mixed with hydrogen peroxide.

The team used the TAML treatment on water containing high levels of BPA at neutral pH, which is the pH typically used for wastewater treatment. 99 percent of the BPA was eliminated from the water in just 30 minutes. 


The study found TAML treatment at this pH caused BPA to assemble into larger units called oligomers, which the researchers determined are not harmful like BPA.Furthermore, it was found that the TAML-treated water did not contain properties that mimicked estrogen. 

When the researchers used the TAML treatment at a pH 11, more than 99.9 percent of BPA was removed within 15 minutes. A pH 8.5 treatment completely eradicated the BPA molecules to the extent that no oligomers were detected.

Why are so many North American whales dying off so quickly?. Whale watching is a beloved pastime worldwide. You can find whale watching tours in Washington, Canada, and parts of New England, just to name a few. But, what could be a once in a lifetime opportunity for you and your family could also pose a deadly threat to the endangered whales in those areas.

Surprisingly, whale watching is actually a contributing factor threatening natural habitats of endangered whales like the humpback whale, the sperm whale, and the northern right whale. Boat collisions account for many whale and marine injuries and deaths and collisions with whale watching tours are more common than you might think. 

And with some whale species with populations continuing to drop at an increasing rate, understanding these threats and how to minimize them could mean life or death for the survival of some species. 

The rare North American right whale is an endangered whale with just 500 left worldwide. And recently, several right whales have been found dead in the Gulf St. Lawrence Gulf in Canada. 

So far there have been nine reported <a href="https://www.earth.com/news/investigate-baby-whale-deaths/">deaths</a> of right whales in the Gulf of St. Lawrence in just two months. 

The cause of these deaths are due to several factors including collisions, fishing operations in those areas, and run ins with natural predators. But there is something about this pattern of deaths that is causing alarm in the scientific community. 

Tonya Wimmer, director of the<a href="https://www.marineanimals.ca/"> Marine Animal Response Society</a>, is heading the investigation into these deaths and their increasing numbers. Wimmer and her team will be performing necropsies, or animal autopsies, on some of the right whales that were found dead.

While certain measures have been taken in Canada to halt fishing operations where those right whales preside, Wimmer and her team want to emphasize the need for long term solutions that will help ensure the safety and survival of right whales and other members of the whale family.

Why are so many North American whales dying off so quickly?

Why are so many North American whales dying off so...

It was supposed to be great stuff. A very effective insulating material that wouldn’t burn or melt, so builders loved it. So did shipbuilders, and manufacturers of automotive and airplane parts and even the makers of such everyday consumer products as toasters and hair dryers. The stuff was incredibly popular in America in numerous industries between the 1930s and the late ‘70s, when it was finally banned in most applications. The stuff was magnesium-silicate mineral fibers. Better known as asbestos.

A Lethal Substance

Today, we know all kinds of reasons not to appreciate this material that was -- and still is -- so prevalent in older homes, factories, warehouses and commercial buildings of all kinds. Namely, it’s deadly.

Long-term asbestos exposure kills some 10,000 Americans annually. The most common and deadly of these asbestos-related diseases is <a href="https://mesothelioma.net/mesothelioma/">mesothelioma</a>. The median survival rate of this cancer of the lung and inner cavity membrane (the mesothelium) is just one year from diagnosis. 

While it kills quickly, the disease manifests slowly over time. From the point of exposure it could take 20 to 40 years or even longer before it develops into mesothelioma. Cigarette smoking compounds the risk of developing asbestos-related diseases. In fact, smoking roughly doubles the odds of contracting mesothelioma. 

Exposure victims can also contract lung cancer and a debilitating respiratory condition called asbestosis. This disease is the result of scarring of the lining of the lungs and can be a precursor to mesothelioma.

The longer a person was exposed and the intensity of that exposure increases the risk of developing an asbestos-related disease.

It’s the durability of this known carcinogen that was so appealing to industry that’s also behind its deadly nature. Asbestos fibers are microscopic, but when they’re breathed in they cling to the respiratory system, including the lining of the lungs -- and literally stick around. For years. For decades. Until symptoms appear. 

The Contractor’s Dream Becomes Our Nightmare

Its excellent heat resistance got asbestos used in roofing shingles, floor tiles, ceiling materials, textile products and automotive parts. Shipbuilders used it (in fact, U.S. Navy vets from the World War II and Korean War era are the highest at-risk group), and the substance was popular at oil refinery plants, railroad yards, power plants and construction sites of all kinds. 

While no exposure to the substance is safe, the most dangerous form of asbestos is an airborne particle. If <a href="https://www.earth.com/news/house-bill-to-update-chemical-regulation-approved-2/">asbestos</a> is anchored to a stable product it’s relatively safe. But if it’s loose -- floating in the air -- it can be breathed in. 

That’s why those at highest risk of exposure today are workers tasked with maintaining or rehabbing older buildings that contain asbestos. The act of carelessly ripping out the material can free the particles. That’s why, today, only licensed and trained removal contractors with protective suits and breathing gear can legally remove and dispose of asbestos from old buildings.

Full Ban Considered

Surprisingly, asbestos is still being used in the United States, though in narrow applications where its used is considered to be comparatively safe. 

The substance is no longer mined domestically, but we imported 340 metric tons of raw asbestos in 2016, according to the EPA. The government agency is considering a full ban on asbestos and other dangerous chemicals under the Frank R. Lautenberg Chemical Safety for the 21st Century Act. 

If you’d like to know more about asbestos and the health risks associated with this deadly substance, or learn how you can get assistance for yourself or loved ones who’ve been exposed, visit <a href="https://mesothelioma.net/">Mesothelioma.net</a> or the <a href="https://www.mesothelioma.com/">Mesothelioma Cancer Alliance</a>.

On the unforgiving landscape of North Greenland, temperatures drop and sunlight barely penetrates through the polar winter. It was here, however, that an international team of scientists found <a href="https://www.earth.com/news/predatory-worms-were-terror-beasts-half-a-billion-years-ago/#google_vignette" target="_blank" rel="noreferrer noopener">evidence of sea monsters</a> that would change our understanding of ocean life in the past.



This video captures the discovery of Timorebestia fossils that had been hidden for more than 500 million years in the Sirius Passet formation. The "terror beasts," as they are called, are a hidden chapter in the evolutionary history of <a href="https://www.earth.com" target="_blank" rel="noreferrer noopener">Earth</a>, showing that sophisticated predator-prey interactions occurred much earlier than previously envisioned.



Dr. Jakob Vinther and his research team at the <a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, in collaboration with researchers at the <a href="https://eng.kopri.re.kr/" target="_blank" rel="noreferrer noopener">Korean Polar Research Institute</a>, braved extreme weather conditions at 82.5 north latitude to locate these giant creatures. Using sophisticated electron microprobe analysis, they revealed the detailed anatomy of the animals, including their muscle and nerve tissues.



The find upsets the traditional timeline of sea predators. Although we've long appreciated that Cambrian oceans were at one time ruled by <a href="https://www.youtube.com/watch?v=jWI3-UgA3_o&amp;list=PL1QLQMW9MWDwpkFOnvgAmu7wT6rZmYqdJ&amp;index=19" target="_blank" rel="noreferrer noopener">arthropods</a>, these discoveries indicate that relatives of arrow worms were first to dominate the seas. These worms were building sophisticated food webs several million years before other predator groups arose.



Each fossil is a story of ancient hunger, with fossil stomach contents revealing these meter-long beasts dined on heavily armored arthropods regularly, cementing their place as the ocean's first apex predators.

<h2 class="wp-block-heading" id="h-385-million-year-old-trees-discovered">385-million-year-old trees discovered</h2>



Scientists have uncovered something extraordinary just two hours north of New York City. The <a href="https://www.earth.com/news/worlds-oldest-forest-discovered-close-to-new-york-city/" target="_blank" rel="noreferrer noopener">world's oldest forest</a>, dating back 385 million years, offers a window into how Earth's first complex forests shaped our planet's atmosphere.



Located near <a href="https://townofcairo.com/" target="_blank" rel="noreferrer noopener">Cairo, New York</a>, in Greene County, these weren't merely primitive plants struggling to survive. These were sophisticated trees with root systems remarkably similar to modern forests. This ancient woodland predates dinosaurs by 140 million years.



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



385 million years ago, upstate New York was a tropical paradise near the equator. Thanks to continental drift, this ancient forest has traveled thousands of miles to its current location.



The fossil forest sits in an abandoned quarry, roughly half the size of a football field. This represents just a slice of what was likely a massive forest system stretching from New York into Pennsylvania.



Charles Ver Straeten, curator of sedimentary rocks at the <a href="https://www.nysm.nysed.gov/" target="_blank" rel="noreferrer noopener">New York State Museum</a>, made the discovery in 2009. While scouting the former highway department property, his trained eye spotted wandering patterns in the stone that looked like marine features.



<h2 class="wp-block-heading" id="h-revolutionary-age-and-preservation">Revolutionary age and preservation</h2>



The site contains 385-million-year-old rocks with fossilized woody roots forming horizontal patterns up to 18 feet (5.5 meters) wide. As Christopher Berry, a paleobotanist at Cardiff University, explains: "You are walking through the roots of ancient trees."



This discovery pushes back advanced tree evolution by millions of years. The research, published in <a href="https://www.cell.com/current-biology/home" target="_blank" rel="noreferrer noopener">Current Biology</a> in December 2019, fundamentally changes our understanding of when complex forests first emerged.



Researchers believe a massive flood buried the forest floor, creating perfect fossilization conditions. Over millions of years, sediment hardened into rock, preserving these root patterns like nature's time capsule.



<h2 class="wp-block-heading" id="h-meet-archaeopteris-the-first-modern-tree">Meet Archaeopteris: the first modern tree</h2>



The star of this ancient forest is Archaeopteris – not to be confused with the feathered dinosaur Archaeopteryx. This tree was far older and more revolutionary.



William Stein from <a href="https://www.binghamton.edu/" target="_blank" rel="noreferrer noopener">Binghamton University</a> describes the roots as "strikingly modern, essentially what you'd see outside in my yard right now." These weren't simple root systems you'd expect from ancient plants.



Some fossilized roots are six inches (15 centimeters) in diameter, forming 36-foot-wide (11-meter) patterns. These giants grew up to 65 feet (20 meters) tall with five-foot-diameter (1.5-meter) trunks.



<h2 class="wp-block-heading" id="h-climate-changing-impact">Climate-changing impact</h2>



These trees fundamentally changed Earth's environment. Kevin Boyce, a Stanford University geoscientist, explains how their deep roots triggered "weathering," chemical reactions that pulled carbon dioxide from the atmosphere.



This process dropped atmospheric CO2 levels from 10-15 times higher than today to roughly modern concentrations. These ancient trees helped create atmospheric conditions that made complex life possible.



<h2 class="wp-block-heading" id="h-ancient-forest-ecosystem">Ancient forest ecosystem</h2>



The forest was remarkably diverse. Scientists identified Eospermatopteris, palm tree-like plants with short roots that reached 30 feet (9 meters) tall but lacked woody structure. The forest also housed cladoxylopsids and a mysterious third species still being studied.



All reproduced through spores rather than seeds – millions of years before seeds evolved. This tropical environment had no grass, flowers, or flying insects, just towering trees creating Earth's first complex forest canopy.



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



Before this finding, the Gilboa forest, located 25 miles (40 kilometers) away, held the "oldest forest" title. Cairo's trees are 2-3 million years older, showing that complex forest ecosystems developed much faster than scientists believed possible.



Patricia Gensel, a <a href="https://www.unc.edu/" target="_blank" rel="noreferrer noopener">University of North Carolina</a> paleobotanist, notes: "The size of those root systems is really changing the picture. Even 20 years ago, researchers assumed trees with such complex root systems didn't evolve so early."



The Cairo site presents three unique root systems, suggesting Devonian period forests were diverse ecosystems with different trees occupying different environmental niches, much like today's forests.



<h2 class="wp-block-heading" id="h-modern-preservation-efforts">Modern preservation efforts</h2>



In 2022, New York State Senator Michelle Hinchey secured a $170,000 grant for the town of Cairo to construct specialized fencing around the fossil forest site. The town plans to conduct a feasibility study exploring the possibility of creating an educational center and working lab on-site.



Joe Hasenkopf, chair of the Cairo Planning Board, hopes to partner with educational institutions to create a research facility serving scientists, students, and the public.



<h2 class="wp-block-heading" id="h-lessons-for-today-s-climate">Lessons for today's climate</h2>



Why does a 385-million-year-old forest matter today? It shows how dramatically forests can change Earth's climate. These ancient woodlands created the atmospheric conditions supporting complex life.



Understanding how prehistoric forests transformed the planet helps us appreciate modern forests' critical role in addressing climate change. Forests remain Earth's most effective carbon capture systems.



These prehistoric trees changed Earth's atmosphere by pulling massive amounts of carbon dioxide from the air. As we face modern climate challenges, this ancient forest reminds us of trees' incredible power to transform our planet's environment.



The next time you walk through a forest, remember you're experiencing an ecosystem whose blueprint was established 385 million years ago in upstate New York. These ancient pioneers didn't just survive – they thrived and changed the world forever.



The full study was published in the journal Current Biology.

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

Mid-July is an opportune time to kick-start a thriving fall garden, and this guide lays out the best vegetables and herbs to plant now for a fruitful autumn harvest. 



Fast-growing leafy greens such as spinach, lettuce, kale, and arugula perform especially well in the waning summer heat, with harvests beginning as soon as 30 days. 



These cool-season crops relish the transition into fall, offering repeated yields with cut-and-come-again methods.



Root vegetables like radishes, carrots, and beets also excel during this period. Radishes deliver satisfaction in under a month, while carrots and beets mature in about two months. Employing succession planting ensures a continuous stream of produce deep into the cooler months. 



For a boost of fresh flavor, herbs like cilantro, basil, dill, and chervil are excellent picks. These heat-loving varieties flourish in July’s warmth and are harvest-ready in about 30 days, especially when sown continuously.



Gardeners in zones 6 through 9 can benefit from planting bush beans and snap peas, which don’t require trellising and are ideal for compact plots. 



Maturing in 50–60 days, they’re a smart choice for quick, protein-rich harvests. For those in hotter regions, heat-tolerant crops such as okra and southern peas provide reliable yields and thrive in scorching conditions.



This guide emphasizes more than crop selection—it highlights the importance of timing, soil preparation, and ongoing sowing techniques. 



With thoughtful planning and attention to regional climate needs, even late-summer gardeners can enjoy fresh salads, hearty stews, and the satisfaction of a robust, homegrown harvest well into fall.

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.

Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Nushagak Bay, a large estuary in southwest Alaska. Nushagak runs mainly north to south and exits in Bristol Bay, a large body of water in the Bering Sea.



"The bay is primarily fed by the Nushagak River, which begins in the Alaska Range and flows southwest approximately 450 km. The bay is also fed by several additional rivers including the Wood, Igushik, Snake and Weary rivers," says ESA.



"The dark colors of the Nushagak River are most likely due to tannins or lignins (chemical substances found in plants). Tannins and lignins from roots, leaves, seeds, bark and soil can leach into the water and give it a brown or even black colour. The sediments then flow southwards where it is mixed with the bluer waters of the bay."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> (ACS) reveals that proteins on flu viruses are actually flexible, tilting and waving in a “breath-like” motion. According to the experts, these proteins could be used to better defend against the flu.



"The main antigenic targets of influenza virus are two surface glycoproteins, hemagglutinin (HA) and neuraminidase (NA). Whereas the structural and dynamical properties of both glycoproteins have been studied previously, the understanding of their plasticity in the whole-virion context is fragmented," wrote the researchers.



To investigate, the team conducted detailed simulations of the influenza A H1N1 virion, or the swine flu. The experts concluded that the visualizations show many new vulnerable states of flu viruses, which could improve future vaccines and antiviral drugs.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Lake Trasimeno, which is located west of Perugia in central Italy. It is the fourth largest lake in the country. While Trasimeno’s water level varies, it has a maximum depth of approximately six meters.&nbsp;



"In this Copernicus Sentinel-2 image, captured on 6 August 2022, the lake’s emerald green colour is likely due to the presence of phytoplankton. Streaks in the water, particularly visible in the west, indicate the presence of soil and sediments which have been stirred up by winds. Dark colored waters in the southern part of the lake indicate a presence of submerged and floating macrophytes (aquatic plants) as well as algae," says ESA.



"Surrounded by hills on three sides, Trasimeno is subject to heavy storms created by winds, especially from the north and west. There are three islets in the lake: Maggiore, Minore and Polvese (the largest). The lake’s shores are sparsely inhabited with only two popular villages: Castiglione del Lago and Passignano sul Trasimeno."



"Italy is experiencing its worst drought in 70 years which has affected drinking water supplies, hydroelectric power and agricultural production. High temperatures, hot winds and lack of rainfall are the main causes of drought in the Umbrian region which saw Lake Trasimeno’s drop 1.3 m, reaching the limit of the hydrometric zero in July 2022."

Today's Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes a new self-powered nanosensor that can instantly detect mercury contamination with the tap of a finger.&nbsp;



The oxidized form of mercury can be harmful when it is ingested through contaminated water or food. This makes it necessary for experts to develop sensors that can quickly and accurately detect the presence of mercury.&nbsp;



Zong-Hong Lin and colleagues have now created a triboelectric nanosensor (TENS) that can detect mercury by simply by touching a sample. According to the researchers, their TENS could serve as the basis for similar devices to safely and remotely monitor other pollutants.

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> explores the ability of salt to transform the way that foods and beverages taste. Salt is known to cover up undesirable flavors, such as bitterness in coffee or beer, but how exactly does sodium chloride change the taste of other compounds?



One previous study showed that, not only does salt suppress bitterness, but also enhances sweetness and sourness. Another study revealed that bitterness reduction by salt seems to be happening at the tongue receptor level as well as in the brain.&nbsp;



While it is known that salt taste is mediated by the presence of sodium channels in the form of taste buds, experts believe that there is also an unknown receptor responsible for how we taste salt that has not yet been identified.&nbsp;

'The weather of Santiago resembles the Mediterranean climate with dry and warm summers with temperatures reaching up to 35°C (from October to March) and cool and humid winters that can drop to 0°C (from April to September)."



"The city lies in the centre of the country’s central valley around 80 km from the Pacific Ocean to the west and borders Argentina to the east. A tiny part of Argentina is visible in the top-right corner of the image where the mountain crest of the Andes Mountains acts as a divider between the two countries," says ESA.

Astronomers at <a href="https://www.jhu.edu/">Johns Hopkins University</a> have created an interactive map of the universe, including the actual position and real colors of 200,000 galaxies. The map allows the public to access data that was previously only available to scientists.



The map was developed using data collected by the Sloan Digital Sky Survey. For over two decades, a telescope in New Mexico was aimed at slightly different locations to capture the night sky.&nbsp;



"Growing up I was very inspired by astronomy pictures, stars, nebulae and galaxies, and now it's our time to create a new type of picture to inspire people," said map creator Brice Ménard, a professor at Johns Hopkins. "Astrophysicists around the world have been analyzing this data for years, leading to thousands of scientific papers and discoveries. But nobody took the time to create a map that is beautiful, scientifically accurate, and accessible to people who are not scientists. Our goal here is to show everybody what the universe really looks like."



"In this map, we are just a speck at the very bottom, just one pixel. And when I say we, I mean our galaxy, the Milky Way which has billions of stars and planets. We are used to seeing astronomical pictures showing one galaxy here, one galaxy there or perhaps a group of galaxies. But what this map shows is a very, very different scale."



"From this speck at the bottom, we are able to map out galaxies across the entire universe, and that says something about the power of science."



The <a href="https://mapoftheuniverse.net/">interactive map</a> is available online, where it can be downloaded for free.

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Dublin, the capital and largest city of Ireland. Beyond its pub culture, Dublin is known as a modern culinary destination and a UNESCO City of Literature.



"Dublin is located near the midpoint of Ireland’s east coast in the province of Leinster. The city, which covers an area of around 115 square kilometers, is bordered by the Dublin Mountains, a low mountain range to the south, and is surrounded by flat farmland to the north and west," says ESA.



"The city straddles the River Liffey, which rises in the Wicklow Mountains and flows around 80 kilometers eastwards through the city of Dublin, in which it is canalised and bordered with quays. It then empties into Dublin Bay, an arm of the Irish Sea."



Dublin has an abundance of green spaces, including one of the largest enclosed public parks in any European capital city. Phoenix Park, which was originally formed as a royal hunting park in the 1660s, includes 707 hectares of green space.

Today's Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the province of Zaragoza in northeast Spain. The image was captured by the Copernicus Sentinel-2 mission.



"Together with the provinces of Huesca and Teruel, Zaragoza formed the old kingdom of Aragon. Its capital, also called Zaragoza (not visible in this image) is home to around half of Aragon’s population," says ESA.



"The Ebro River can be seen winding its way through the province from west to east in this image. Between its source in the Cantabrian Mountains in the northwest and its delta on the Mediterranean coast, the Ebro River is fed by more than 200 tributaries as it flows 910 km across much of northern Spain."



Since rainfall is very scarce in this region, irrigation in the Ebro basin is critically important. In the valleys surrounding the Ebro River, many fields are used for growing crops such as corn, wheat, and barley.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features the Pyrenees Mountains, which form a natural boundary between France and Spain in southwest Europe.



The mountain range is 430 kilometers in length. It stretches from the Mediterranean Sea on the east to the Atlantic Ocean on the west.



At an elevation of 3404 meters, Pico de Aneto is the highest mountain peak in the Pyrenees, and the third-highest peak in Spain. Pico de Aneto is located in the Posets-Maladeta Natural Park, which spans more than 82,000 acres.&nbsp;



"Geological studies have revealed that the Pyrenees Mountains have been around for longer than the Alps, with their sediments first deposited in coastal basins during the Paleozoic and Mesozoic eras," reports ESA.



"The entire mountain range formed due to the upwelling of large sedimentary rocks by the collision of the Iberian and the Eurasian plate around 100 to 150 million years ago, followed by intense erosion from ice and water."



The western Pyrenees receive more precipitation due to moisture blowing in from the Atlantic Ocean. The mountain range contains many lakes, several small glaciers, and some of the highest waterfalls in Europe.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes two exoplanets that are orbiting a star 218 light-years away. A team of researchers led by the University of Montreal has found evidence that these planets are "water worlds."



The experts used data from NASA’s Hubble and Spitzer Space Telescopes. They discovered that exoplanets Kepler-138 c and Kepler-138 could be composed largely of water.



"We previously thought that planets that were a bit larger than Earth were big balls of metal and rock, like scaled-up versions of Earth, and that's why we called them super-Earths," explained study co-author Björn Benneke.&nbsp;



"However, we have now shown that these two planets, Kepler-138 c and d, are quite different in nature and that a big fraction of their entire volume is likely composed of water. It is the best evidence yet for water worlds, a type of planet that was theorized by astronomers to exist for a long time."
