Can farms produce enough food to feed us while still leaving space for wildlife? A new proposal says they can.



By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables.



<h2 class="wp-block-heading" id="h-farming-with-wildlife-in-mind">Farming with wildlife in mind</h2>



The plan comes from ecologists at the <a href="https://www.ceh.ac.uk/">UK Centre for Ecology &amp; Hydrology</a> and the University of Alcalá in Spain. Study co-author Professor James Bullock elaborated on the importance of the research.



“Reversing <a href="https://www.earth.com/news/un-report-calls-for-global-change-to-stop-biodiversity-loss/">biodiversity loss</a> and degradation of ecosystems is essential both for nature as well as long-term global food security. But there is no single silver bullet for nature recovery and so far it has been unclear how to integrate rewilding into agricultural landscapes," said Professor Bullock. 



“Our proposed approach moves beyond land sparing versus land sharing. We believe rewilding can be interwoven into agricultural landscapes and could be key to maintaining <a href="https://www.earth.com/news/increasing-plant-based-food-production-would-have-extremely-positive-impact/">food production</a> in a way that is sustainable in the long term for people and the planet.”



<h2 class="wp-block-heading" id="h-dedicating-land-to-nature-recovery">Dedicating land to nature recovery</h2>



According to the study, fostering rewilding approaches alongside farming could create agroecological landscapes that accommodate biodiversity while remaining resilient and functionally connected. Certain incentives would encourage farmers to adopt this approach.



“While setting aside land for nature recovery could potentially be made a legal requirement for farmers and landowners, there is more likely to be acceptance and success of rewilding if there are incentives in the form of payments for ecosystem services and tax deductions,” noted Professor José María Rey Benayas, lead author on the study.



<h2 class="wp-block-heading" id="h-why-farming-needs-wildlife">Why farming needs wildlife</h2>



Modern farming has greatly increased food production since the 1940s. But this has often come at the expense of nature. 



Clearing land, using heavy fertilizers and pesticides, and removing natural features like hedgerows have pushed many plant and animal species to the edge.



This loss doesn’t just affect wildlife - it disrupts vital services that farms depend on, such as healthy soil, natural pest control, and water retention. As these services decline, the long-term productivity and resilience of farming systems are put at risk.



<h2 class="wp-block-heading" id="h-the-cost-of-declining-wildlife">The cost of declining wildlife</h2>



Across Europe and beyond, once-common species are disappearing from farmland. For example, the U.K. has lost over 40 million birds since 1970, and wild bee populations have declined in more than half of European countries, according to multiple long-term surveys.



These animals aren’t just part of the scenery - they’re key to food production. Birds eat crop pests. Bees and other insects pollinate the flowers that develop into fruits and vegetables. Their loss means greater reliance on artificial fertilisers, pesticides, and expensive manual labour.



Bringing wildlife back isn’t just a conservation goal - it’s a practical step toward more affordable and reliable <a href="https://www.earth.com/news/mixed-cover-crops-may-be-the-future-of-sustainable-farming/">farming</a>.



<h2 class="wp-block-heading" id="h-steps-to-farming-alongside-wildlife">Steps to farming alongside wildlife </h2>



The researchers suggest a four-part plan that links nature conservation with everyday farming. 



First, they recommend reserving at least 20% of farmland for nature. This space would include large patches of woodland, wetlands, and species-rich grassland to form strong core habitats. 



Second, these patches should be connected by green corridors - such as hedgerows, ponds, and strips of scrubland - that allow wildlife to move, feed, and reproduce.



Third, they propose protecting small hotspots within working fields. This would involve setting aside about 10% of cropped land for flower strips, beetle banks, and bird perches, bringing the total to the 30% global restoration goal. 



Finally, they call for small changes in daily farming practices, like reducing chemical use, planting flowers for <a href="https://www.earth.com/news/pollinators-face-extinction-risk-due-to-climate-change/">pollinators</a>, and letting livestock graze more freely to help spread seeds and support healthy soil.



<h2 class="wp-block-heading" id="h-rewilding-has-benefits-for-farmers">Rewilding has benefits for farmers</h2>



Many European regions cannot host bears or bison. However, smaller species such as lynx, wildcat, or European hare can still boost ecosystem health. Choosing the right mix depends on local conditions.



Helping wildlife can pay off in more ways than one. When farms support natural habitats, they often see practical benefits in return. 



Better soil retains more water and nutrients, which supports stronger <a href="https://www.earth.com/news/farmers-can-help-make-crops-more-resilient/">crops</a>. Pollinators and natural predators of pests can help increase yields in nearby fields. 



Farmers may also spend less on fertilizers and pesticides, lowering overall input costs. In some places, governments might provide payments or tax breaks to reward efforts that support biodiversity and ecosystem services.



<h2 class="wp-block-heading" id="h-making-room-for-wildlife">Making room for wildlife</h2>



Reaching the 20% target may be challenging for small farms, but collective action can make it achievable. At the same time, each region will need to adapt the plan to fit its local conditions. 



Areas with heavily degraded farmland have the most to gain, while places with traditional, low-impact farming may require fewer changes. 



The researchers emphasize that this is just a starting point - but the message is clear: making room for wildlife alongside farming can help secure both indigenous species and food for the future.

Farming for wildlife: How traditional practices can protect nature

Can farms produce enough food to feed us while still leaving space for wildlife? A new proposal says they can. By setting aside one-fifth of farmland for nature, and tweaking everyday practices on the rest, we can help wildlife recover without sacrificing the food on our tables. Farming with wildlife in mind The plan comes from ecologists at the UK Centre for Ecology &amp; Hydrology and the University of Alcalá in Spain. Study co-author Professor James Bullock elaborated on the importance of the research. “Reversing biodiversity loss...

In a new study published by <a href="https://www.wiley.com/en-us">Wiley</a>, researchers have determined that unmasked speech in confined spaces poses the greatest risk of spreading the <a href="https://www.earth.com/news/new-coronavirus-identified-that-has-originated-in-dogs/">virus</a> that causes COVID-19.

"We've all seen some spit droplets flying when people talk but there are thousands more, too small to be seen by the naked eye," said study senior author Dr. Adriaan Bax. He explained that when the water evaporates from speech-generated droplets, they float in the air for minutes, like smoke.

"The SARS-CoV-2 virus is highly contagious, as demonstrated by numerous well-documented superspreading events. The infection commonly starts in the upper respiratory tract (URT) but can migrate to the lower respiratory tract (LRT) and other organs, often with severe consequences," wrote the study authors. 

"Whereas LRT infection can lead to shedding of virus via breath and cough droplets, URT infection enables shedding via abundant speech droplets. Their viral load can be high in carriers with mild or no symptoms, an observation linked to the abundance of SARS-CoV-2-susceptible cells in the oral cavity epithelium."

The researchers explained that expelled droplets rapidly lose water through evaporation, with the smaller ones transforming into long-lived aerosols. 

"Although the largest speech droplets can carry more virions, they are few in number, fall to the ground rapidly and therefore play a relatively minor role in transmission. Of more concern is small speech aerosol, which can descend deep into the LRT and cause severe disease," said the researchers.

"However, since their total volume is small, the amount of virus they carry is low. Nevertheless, in closed environments with inadequate ventilation, they can accumulate, which elevates the risk of direct LRT infection."

The experts report that a large fraction of intermediate-sized speech aerosols can linger in air for minutes and can be transported over considerable distances by convective air currents. 

"The abundance of this speech-generated aerosol, combined with its high viral load in pre- and asymptomatic individuals, strongly implicates airborne transmission of SARS-CoV-2 through speech as the primary contributor to its rapid spread."

The study is published in the <a href="https://onlinelibrary.wiley.com/journal/13652796">Journal of Internal Medicine</a>.

Speech is the biggest spreader of COVID-19

In a new study from the <a href="https://www.unimelb.edu.au/">University of Melbourne</a>, experts have discovered that young clownfish exposed to artificial light are struggling to survive. The researchers found that juvenile clownfish living closest to shore are dying faster than those located farther offshore.

The scientists also determined that the surviving clownfish living near artificial light developed more slowly than clownfish under natural lighting conditions by 44 percent.

Professor Stephen Swearer said the team exposed 42 clownfish in their host anemones to either artificial light at night (ALAN) or natural light in the lagoon. The clownfish were monitored for over nearly two years.

"The impacts of light pollution found here are probably underestimated and mitigation measures and policy changes are urgently required," said Professor Swearer.

Study lead author Jules Schligler is an expert at the École Pratique des Hautes Études PSL Université Paris (EPHE) and the Centre of Island Research and Environmental Observatory (CRIOBE). He noted that clownfish can live in shallow coastal waters and are highly sedentary living in anemones, which means they can be easily impacted by night lights from streetlights, piers. or ports.

"As with many other reef fish, clownfish feed, reproduce, defend their territories and interact with other fish during the day and reset whilst sleeping at night. However, 36 per cent of the clownfish exposed to light pollution were more likely to die than fish under natural light cycles," said Schligler. "Like humans, fish need a period of inactivity, which is crucial for their well-being."

According to the researchers, even the fish that survived did not entirely escape the effects of artificial light as they grew less than fish from the control group.

"This is the first time that the impacts of ALAN have been tested on a coral reef fish in the wild and over such a long time," said study co-author Daphne Cortese.

"As 12 percent of all coral reef fish live in close association with another sedentary species, such as a coral or anemone, light pollution could already be having severe negative impacts on a fifth of fringing reef fish populations."

The experts hope their research will help raise awareness of the impacts of ALAN on coastal marine ecosystems.

"Many marine protected areas are impacted by light pollution at night, and authorities are not taking this pollution into account," said study co-author Professor Ricardo Beldade of the Pontificia Universidad Católica de Chile. "We hope that policy makers take this threat much more seriously for future management strategies."

In a new study from the <a href="https://www.southampton.ac.uk/">University of Southampton</a>, experts have linked the clearing of a tropical forest in Central America to darker waters off the coast of Belize. The potential impacts of the darkened water on marine life are not yet known. 

Deforestation and other land use changes alter the color, amount, and composition of organic materials that runoff and flow through rivers. Much of this material is not decomposing before it reaches the ocean, with widespread implications for ecosystems.

The researchers set out to investigate the effects of deforestation on the coastal environment by studying material that flowed into rivers from a Central American rainforest. The team tracked the material to the water off the coast of Belize, home to the world's second largest reef.

"Like many countries in the region, Belize is experiencing a rapid rate of deforestation due to increasing need for agricultural and urban land, whilst the economy also relies on the fishing and tourism industries on the coastline," said study lead author Stacey Felgate.

"Despite this, there has been very little research into the impact that changing land-use at such a fast pace is having on the region's coastal ecosystems."

The experts found that more colored material is running off into rivers from land used for farming compared to land that is forested. 

The researchers discovered that, instead of getting broken down. the dark material accumulated as it moved farther along in the river. 

The dark-colored material absorbs light and darkens the seawater along the coast. This means that less sunlight is reaching marine life such as seagrass and corals that need it to grow. 

"The potential for human activities on land to negatively impact the coastal environment is not unique to Belize, and so our findings are relevant more broadly, particularly for coastal developing nations where deforestation is ongoing but there are no integrated conservation plans between what is happening on land and what is happening in the oceans," said Felgate.

The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/journal/21698961">JGR Biogeosciences</a>.

Deforestation has darkened coastal waters off Belize

In a new study from the University of Southampton, experts...

A recent study led by <a href="https://www.ucl.ac.uk/">University College London</a> suggests that sea ice in coastal regions of the <a href="https://www.earth.com/news/arctic-warming-is-not-properly-represented-in-climate-targets/">Arctic</a> is thinning at up to double the rate that was expected. 

The researchers used a new computer model designed to estimate snow depth as it varies year to year. The results showed that coastal Arctic sea ice is thinning 70 to 100 percent faster than previously thought.

"The thickness of sea ice is a sensitive indicator of the health of the Arctic," said study lead author Robbie Mallett. "It is important as thicker ice acts as an insulating blanket, stopping the ocean from warming up the atmosphere in winter, and protecting the ocean from the sunshine in summer. Thinner ice is also less likely to survive during the Arctic summer melt."

"Previous calculations of sea ice thickness are based on a snow map last updated 20 years ago. Because sea ice has begun forming later and later in the year, the snow on top has less time to accumulate. Our calculations account for this declining snow depth for the first time, and suggest the sea ice is thinning faster than we thought."

According to study co-author Professor Julienne Stroeve, there are a number of uncertainties in measuring sea ice thickness, but the researchers believe their new calculations represent a major step forward in terms of more accurately interpreting satellite data.

"We hope this work can be used to better assess the performance of climate models that forecast the effects of long-term climate change in the Arctic - a region that is warming at three times the global rate, and whose millions of square kilometres of ice are essential for keeping the planet cool."

The experts used radar from the European Space Agency's CryoSat-2 satellite to calculate sea ice thickness. They combined the data with a new computer model that calculates snow depth and density using inputs such as air temperature, snowfall, and ice motion. 

Based on this information, the team estimated the overall rate thinning sea ice in the Arctic, as well as the variability of sea ice thickness from year to year.

When compared to earlier calculations, the rate of decline had increased across the three coastal seas of Laptev, Kara and Chukchi seas by 70, 98, and 110 percent respectively. Furthermore, across all seven coastal seas, the variability in sea ice thickness from year to year increased by 58 percent.

The rapid thinning of sea ice in the coastal Arctic seas has implications for human activity in the region, both in terms of shipping along the Northern Sea Route for a larger part of the year, as well as the extraction of resources from the sea floor such as oil, gas and minerals.

"More ships following the route around Siberia would reduce the fuel and carbon emissions necessary to move goods around the world, particularly between China and Europe. However, it also raises the risk of fuel spillages in the Arctic, the consequences of which could be dire," said Mallett. 

"The thinning of coastal sea ice is also worrying for indigenous communities, as it leaves settlements on the coast increasingly exposed to strong weather and wave action from the emerging ocean."

The study is published in the journal <a href="https://www.the-cryosphere.net/">Cryosphere</a>.

The world must honor its commitment to restore at least one billion degraded hectares of land in the next decade in order to address the triple threat of climate change, <a href="https://www.earth.com/news/changes-in-fish-biodiversity-lead-to-lower-nutritional-quality/">biodiversity</a> loss, and pollution. This is the message of a new report from the <a href="https://www.unep.org/">UN Environment Programme</a> (UNEP) and the <a href="http://www.fao.org/home/en/">Food and Agriculture Organization of the UN</a> (FAO).

According to the study authors, humanity is using about 1.6 times the amount of services that nature can provide sustainably. In order words, conservation efforts will not be enough to prevent large-scale ecosystem collapse and biodiversity loss. 

Worldwide, the costs of terrestrial restoration are estimated to reach at least $200 billion per year by 2030. The researchers found that every $1 invested in restoration creates up to $30 in economic benefits.

Restoration is urgently needed for terrestrial ecosystems including farmlands, forests, grasslands and savannahs. The experts report that some of the world's poorest communities are living across two billion degraded hectares of land.

"This report presents the case for why we must all throw our weight behind a global restoration effort. Drawing on the latest scientific evidence, it sets out the crucial role played by ecosystems, from forests and farmland to rivers and oceans, and it charts the losses that result from a poor stewardship of the planet," wrote UNEP Executive Director Inger Andersen and FAO Director-General QU Dongyu.

"Degradation is already affecting the well-being of an estimated 3.2 billion people - that is 40 percent of the world's population. Every single year we lose ecosystem services worth more than 10 percent of our global economic output."

Ecosystem restoration leads to "massive gains," explained the study authors, such as cleaner air and water, extreme weather mitigation, improved human health, and recovered biodiversity. The restoration process involves practices ranging from reforestation to re-wetting peatlands.

Actions that prevent, halt and reverse degradation are necessary to meet the Paris Agreement target of keeping global temperature rise below two degrees Celsius, noted the researchers. 

The experts also pointed out that restoration, if combined with the protection of natural ecosystems, may help avoid 60 percent of expected biodiversity extinctions.

Eating a plant-based dinner could reduce the risk of heart disease by ten percent, according to a new study from the <a href="https://www.endocrine.org/">Endocrine Society</a>. The researchers found that people who eat too many refined carbs and fatty meats at dinner have a greater chance of developing heart disease than those who eat the same type of foods for <a href="https://www.earth.com/news/coffee-before-breakfast-has-a-negative-impact-on-metabolism/">breakfast</a>.

Congestive heart failure, heart attack, stroke, and other cardiovascular diseases are the number one cause of death. The World Health Organization reports that 17.9 million people die each year from cardiovascular disease, which accounts for 31 percent of all deaths worldwide. 

The risk of developing cardiovascular disease is higher among people who regularly consume saturated fat, processed meats, and added sugar. By contrast, eating a heart-healthy diet with more vegetables and grains and less meat can significantly offset the risk of cardiovascular disease.

"Meal timing along with food quality are important factors to consider when looking for ways to lower your risk of heart disease. Our study found people who eat a plant-based dinner with more whole carbs and unsaturated fats reduced their risk of heart disease by ten percent," said study co-author Ying Li of the Harbin Medical University. 

The researchers analyzed data from the National Health and Nutrition Examination Survey (NHANES) involving 27,911 adults in the United States. Dietary information had been collected during interviews with the participants over two non-consecutive days. 

The team compared the participants' rates of heart disease with eating various fats, carbohydrates, and proteins at breakfast or dinner. The data revealed that eating a plant-based dinner correlated with a 10 percent lower risk of cardiovascular disease.

"It's always recommended to eat a healthy diet, especially for those at high risk for heart disease, but we found that eating meat and refined carbs for breakfast instead of dinner was associated with a lower risk," said Li.

The study is published in the <a href="https://academic.oup.com/jcem">Journal of Clinical Endocrinology &amp; Metabolism</a>.

People who had mild cases of <a href="https://www.earth.com/news/neurological-problems-affect-8-out-of-10-covid-19-patients/">COVID-19</a> have develop antibody-producing cells that can last a lifetime, according to a new study from the <a href="https://medicine.wustl.edu/">Washington University School of Medicine</a>. The findings suggest that, among people who experienced mild COVID-19 symptoms, repeated infections are likely to be uncommon.

"Last fall, there were reports that antibodies wane quickly after infection with the virus that causes COVID-19, and mainstream media interpreted that to mean that immunity was not long-lived," said study senior author Dr. Ali Ellebedy.

"But that's a misinterpretation of the data. It's normal for antibody levels to go down after acute infection, but they don't go down to zero; they plateau. Here, we found antibody-producing cells in people 11 months after first symptoms. These cells will live and produce antibodies for the rest of people's lives. That's strong evidence for long-lasting immunity."

A viral infection causes antibody-producing immune cells to rapidly multiply and circulate in the blood. Most of these cells die once the infection subsides, but some of them migrate to the bone marrow. These antibody-producing cells are known as long-lived plasma cells, or LLPCs.

Once LLPCs have settled into the bone marrow, they continuously secrete low levels of antibodies into the bloodstream to help guard against another infection from the virus.

Dr. Ellebedy realized that the key to figuring out whether COVID-19 leads to long-lasting antibody protection lies in the bone marrow. 

In addition to tracking antibody levels in blood samples from COVID-19 survivors, the team obtained bone marrow from 18 individuals seven or eight months after they had a mild infection. Four months later, some of the participants provided a second bone marrow sample. The scientists also analyzed bone marrow from 11 people who had never had COVID-19 for comparison.

The study revealed that, as expected,  antibody levels in the blood of the COVID-19 participants dropped quickly in the first few months after infection before leveling off. Some antibodies were detectable even 11 months after infection. 

Furthermore, most of the bone marrow samples from people who had had COVID-19 contained antibody-producing cells specifically targeting the virus that causes the disease. These LLPCs persisted, and were detectable months later in the second round of bone marrow samples.

By contrast, the participants who had never had COVID-19 possessed no such antibody-producing cells in their bone marrow.

"People with mild cases of COVID-19 clear the virus from their bodies two to three weeks after infection, so there would be no virus driving an active immune response seven or 11 months after infection," said Dr. Ellebedy. 

"These cells are not dividing. They are quiescent, just sitting in the bone marrow and secreting antibodies. They have been doing that ever since the infection resolved, and they will continue doing that indefinitely."

The researchers speculate that people who were infected and never had symptoms may also be left with long-lasting immunity. However, they noted that it is yet to be determined whether those who endured more severe infection would be protected against a future bout of disease.

"It could go either way," said study first author Dr. Jackson Turner. "Inflammation plays a major role in severe COVID-19, and too much inflammation can lead to defective immune responses." 

"But on the other hand, the reason why people get really sick is often because they have a lot of virus in their bodies, and having a lot of virus around can lead to a good immune response. So it's not clear. We need to replicate the study in people with moderate to severe infections to understand whether they are likely to be protected from reinfection."

The researchers are currently investigating whether vaccination may also induce long-lasting antibodies.

The study is published in the journal <a href="https://www.nature.com/">Nature</a>.

Heat-induced male infertility will cause some species to fall victim to <a href="https://www.earth.com/image/zombie-fires-becoming-more-common-as-the-climate-warms/">climate</a> change earlier than expected, according to an alarming new study from the <a href="https://www.liverpool.ac.uk/">University of Liverpool</a>. The experts report that male fertility losses at high temperatures may affect as many as half of all species. 

"Our work emphasizes that temperature-driven fertility losses may be a major threat to biodiversity during climate change," said Dr. Tom Price. "We already had reports of fertility losses at high temperatures in everything from pigs to ostriches, to fish, flowers, bees, and even humans. Unfortunately, our research suggests they are not isolated cases, and perhaps half of all species will be vulnerable to thermal infertility."

Previous research on temperature tolerance has been primarily focused on identifying the heat thresholds that are lethal to organisms, rather than investigating the temperatures at which organisms can no longer breed.

"Our findings strongly suggest that where species can survive in nature is determined by the temperature at which males become sterile, not the lethal temperature," explained lead researcher Dr. Steven Parratt.

"Unfortunately, we do not have any way to tell which organisms are fertile up to their lethal temperature, and which will be sterilised at cooler temperatures. So, a lot of species may have a hidden vulnerability to high temperatures that has gone unnoticed. This will make conservation more difficult, as we may be overestimating how well many species will do as the planet warms."

The study was focused on 43 fruit fly species. The experts found that in nearly half of the species, male fertility was lost at temperatures that were below lethal thresholds. For example, Drosophila lummei males were found to become sterile at four degrees below their lethal limit. 
The researchers constructed a model for one of the Drosophila species using temperatures projected for 2060. The study revealed that more than half of areas with temperatures below the lethal level will still be hot enough to compromise male fertility.
"We now urgently need to understand the range of organisms likely to suffer thermal fertility losses in nature, and the traits that predict vulnerability," explained Dr. Price. "We must understand the underlying genetics and physiology, so we can predict which organisms are vulnerable, and perhaps produce breeds of livestock more robust to these challenges."

Dr. Simon Kerley is the of the Head of Terrestrial Ecosystems at the Natural Environment Research Council. He said the study turns our thinking of the role, rate, and impact of climate change on its head. 

"It really starts to shed light on the hidden and subtle impact of the changing conditions on the myriad of animals that we perhaps take for granted and have not previously considered 'at risk' from our changing climate. Importantly, it alerts us to the understanding this risk could occur sooner than we thought."

"This piece of work takes biology, at its most fundamental level, and explores it in a well-known and understood laboratory animal, but then takes that crucial extra step of relating it to the real world and the potential impact if may have on global biodiversity."

"With the COP15 and COP26 conferences taking place this year, this study serves as a timely reminder of the need to research and better understand the relationship between climate change and biodiversity loss. The Natural Environmental Research Council will continue to fund this vital research, and UKRI as a whole will work as part of the global effort to safeguard the natural environment for generations to come."

The study involved collaborators from the University of Leeds, University of Melbourne, University of Zürich, and Stockholm University and was funded by the UK Natural Environment Research Council (NERC).

The work is published in the journal <a href="https://www.nature.com/nclimate/">Nature Climate Change</a>.

Scientists have discovered a new type of coronavirus in human patients hospitalized with pneumonia that originated in dogs. If confirmed as a pathogen, this may be the eighth unique coronavirus known to cause disease in humans.

According to a report from <a href="https://www.reuters.com/">Reuters</a>, the researchers tested nasal swab samples taken from 301 pneumonia patients at a hospital in the east Malaysian state of Sarawak. Eight of the samples came back positive for a canine coronavirus.

Genetic testing showed that the new virus, known as CCoV-HuPn-2018, shares characteristics with other coronaviruses known to have infected cats and pigs. However, the strain was found to be mostly similar to one that is known to have infected dogs.

The experts report that the coronavirus also contained a genetic deletion, or mutation, that was not found in any known canine coronaviruses but was present in human strains such as SARS-COV and SARS-COV-2. The source of SARS-COV-2, which causes COVID-19, has not yet been identified.

While the findings indicate that the virus likely jumped from animals to humans, and did so recently, the researchers stress that more studies are needed to determine whether it can be transmitted between people.

“At this point, we don’t see any reasons to expect another pandemic from this virus, but I can’t say that’s never going to be a concern in the future,” said Professor Anastasia Vlasova of The Ohio State University.

She conducted the study with Professor Gregory C. Gray at the Duke University School of Medicine, and Professor Teck-Hock Toh of SEGi University in Sarawak, Malaysia.

The study authors emphasize that it is unclear whether the virus can make people sick, noting that it is possible it was merely "carried" in the patient's airways without causing disease.

“We don’t really have evidence right now that this virus can cause severe illness in adults,” said Professor Vlasova, who noted that only one person in the study found to have been infected with the new coronavirus was an adult. 

“I cannot rule out the possibility that at some point this new coronavirus will become a prevalent human pathogen. Once a coronavirus is able to infect a human, all bets are off.”

“If you had mentioned this 20 years ago, that a virus that affects dogs could change to be able to infect people, many would have been skeptical." 

Professor Vlasova added that even though this new coronavirus comes from a dog, it may not be necessary for people to change how they interact with their dogs in light of this study.

“We are likely missing important animal viruses that are beginning to adapt to humans,” said Professor Gray. 

“We need to conduct such virus discovery work among people with pneumonia and also among people who have intense exposure to animals so that we get early warning of a new virus which may become a future pandemic virus.”

The study is published in the journal <a href="https://academic.oup.com/cid">Clinical Infectious Diseases</a>.

The global <a href="https://www.earth.com/news/rewilding-the-ocean-will-help-mitigate-impacts-of-climate-change/">climate</a> goals defined in the Paris Agreement must be reevaluated to account for the consequences of accelerated Arctic warming, according to a new report from the <a href="https://www.woodwellclimate.org/">Woodwell Climate Research Center</a>.

More than five years ago, the Paris Agreement set specific standards for reducing greenhouse gas emissions and limiting global warming. More than 70 countries even went a step further by adopting ambitious Nationally Determined Contributions that exceed the commitments established in the treaty. 

But now, experts argue that these commitments are outdated because they do not consider the latest science on Arctic feedback loops associated with thawing permafrost. The researchers are calling for global leaders to rethink emissions goals.

"Arctic warming poses one of the greatests risks to our climate, yet it has not been adequately incorporated into existing climate projections and policies," said study lead author Dr. Sue Natali. "To build effective policy to address the climate crisis, it is essential that we recognize the full scope of the problem."

Rapid Arctic warming in the last decade is linked to record-breaking Siberian heatwaves, the loss of Arctic sea ice, extreme northern wildfires, and unexpected rates of permafrost thaw.

In particular, Arctic permafrost has been storing carbon for thousands of years. The permafrost contains approximately twice the amount of carbon that is currently in the Earth's atmosphere, and this carbon is being released into the atmosphere as it thaws. 

The carbon dioxide emissions from permafrost speed up the rate of warming, which leads to further thawing of the permafrost. This reinforcing feedback loop has the potential to exponentially increase carbon dioxide emissions.

The new report warns that current carbon budgets fail to account for the additional carbon dioxide emissions from permafrost, or for the dangerous feedback loops that result.

"Based on what we already know about abrupt thaw and wildfire, these feedback loops are likely to substantially exacerbate the permafrost thaw feedback and resulting carbon emissions," said study co-author Dr. Rachael Treharne. "Unless our models account for these anticipated effects, we'll be missing a major piece of the carbon puzzle."

In order to limit global warming to 1.5 or two degrees Celsius, as outlined by the Paris Agreement, the experts recommend for the latest science on Arctic carbon emissions to be incorporated into the climate models and carbon budgets used to inform policy. In addition, risk assessments must be updated to determine how quickly emissions must be reduced to meet global climate targets. 

"The science alone is not enough," said Dr. Philip Duffy. "We urgently need communication between scientific and policy communities to make sure our climate policies are effective in addressing the scale and scope of the climate crisis."

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Experts at the <a href="https://www.stevens.edu/">Stevens Institute of Technology</a> have investigated the economic impacts of Hurricane Sandy that can be tied to human-caused <a href="https://www.earth.com/news/one-third-of-food-production-threatened-by-climate-change/">climate</a> change. The researchers found that sea level rise is responsible for $8.1 billion in damages, and caused an additional 71,000 people and 36,000 homes to be exposed to flooding from the hurricane.

In 2012, Hurricane Sandy struck the northeast U.S. coast, causing destruction that is estimated at $62.7 billion. The new study links 13 percent of the storm's damages to human-induced sea level rise.

"This study is the first to isolate the human-contributed sea level rise effects during a coastal storm and put a dollar sign to the additional flooding damage," said study co-author Professor Philip Orton. 

"With coastal flooding increasingly impacting communities and causing widespread destruction, pinpointing the financial toll and the lives affected by climate change will hopefully add urgency to our efforts to reduce it."

According to the research, human-caused climate warming had raised the sea level in New York, New Jersey, and Connecticut by roughly four inches over the century preceding the storm. This empowered the storm to penetrate further inland, increasing the amount of flooding and damage to structures.

The researchers hope to apply the approach used in this study to investigate the costs of human-caused sea level rise in other regions, such as the Gulf of Mexico.

"If we were to calculate the costs of climate change across all flooding events - both nuisance floods and those caused by extreme storm events - that figure would be enormous," said Orton. "It would provide clarity on the severe damage we are inflicting on ourselves and our planet."

The study is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.

Decades after the Griffon Vulture vanished from its <a href="https://www.earth.com/news/social-bonds-are-key-to-breeding-success-among-pelicans/">breeding</a> ground in the Eastern Balkan Mountains, the bird has made a remarkable return to the region, according to a study published by <a href="https://pensoft.net/">Pensoft</a>.  

Three local conservation organizations, including the <a href="https://www.rspb.org.uk/our-work/policy-insight/species/birds-of-prey-in-the-uk/why-should-we-protect-birds-of-prey/">Birds of Prey Protection Society</a>, have been working on a long-term restoration program to bring vultures back to their former breeding range in Bulgaria since 2009.

"The Griffon Vulture Gyps fulvus is a Western Palearctic cliff-nesting social obligate scavenger and one of the largest birds of prey in Europe. It used to be widespread and numerous in Bulgaria up to the 1940s, but became less frequently observed and likely became extinct as a breeding species around the 1970s," wrote the researchers.

"The Eastern Balkan Mountains and the area of the town of Kotel were amongst the last sites where breeding of the species was reported."

Between 2009 and 2020, a total of 153 Griffon Vultures were tagged and released from five sites in Bulgaria. The first successful reproduction was reported as early as 2016. 

By December of 2020, the local population had grown to more than 80 permanently present individuals, including about 25 breeding pairs and more than 30 chicks.

"Why vultures of all creatures? Because they were exterminated, yet provide an amazing service for people and healthy ecosystems," explained Elena Kmetova-Biro, initial project manager for the Green Balkans NGO.

According to the experts, many of the vultures were killed shortly after release  due to electrocution. 

"The birds predominantly forage on feeding sites, where the team provides dead domestic animals collected from local owners and slaughterhouses," said the researchers.

"We, however, consider the establishment phase of the reintroduction of Griffon Vulture in this particular site as successfully completed."

"The population is still dependent on conservation measures (supplementary feeding, isolation of dangerous power lines and accidental poisoning prevention), but the area of the Eastern Balkan Mountains can currently be regarded as a one of the only seven existing general areas for the species in the mainland Balkan Peninsula and one of the five which serve as population source sites."

The study is published in the journal <a href="https://bdj.pensoft.net/">Biodiversity Data Journal</a>.

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.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">
https://youtu.be/Ug657J67iEo?si=w96YjGMsg939LD_3
</div></figure>



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."

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;

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."

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes a new map of Mars that is providing insight into the planet’s watery past. The map also reveals where future missions could safely land on Mars.&nbsp;



The map has been created over the last decade using observations of water-rich rocks and mineral deposits. The images were captured by ESA’s Mars Express and NASA’s Mars Reconnaissance Orbiter.



"A big surprise is the prevalence of these minerals, with the map revealing hundreds of thousands of water-affected locations in the oldest parts of the planet," says ESA. "The new data will help answer exciting questions about Mars’ climate history, whether water was globally persistent or confined to short, intense episodes, and whether the conditions were ever suitable for life."



"Specifically, the map shows the locations and abundances of aqueous minerals. These are from rocks that have been chemically altered by the action of water in the past, and have typically been transformed into clays and salts."



According to John Carter of the Institut d’Astrophysique Spatiale (IAS), our collective understanding of Mars has been oversimplified. He explained that planetary scientists have tended to think that only a few types of clay minerals on Mars were created during its wet period, then as the water gradually dried up, salts were produced across the planet.



The new map shows that the composition of Mars is much more complicated than what we thought. For example, while many salts formed after Martian clays, there are some salts that are presumed to be older than some of the clays.&nbsp;



“The evolution from lots of water to no water is not as clear cut as we thought, the water didn’t just stop overnight. We see a huge diversity of geological contexts, so that no one process or simple timeline can explain the evolution of the mineralogy of Mars. That’s the first result of our study. The second is that if you exclude life processes on Earth, Mars exhibits a diversity of mineralogy in geological settings just as Earth does,” said Carter.

Today's Video of the Day from the <a href="https://www.stowers.org/">Stowers Institute for Medical Research</a> describes how cavefish adapted to a sedentary lifestyle over tens of thousands of years. 



The experts found that the muscle metabolism of cavefish has been genetically reprogrammed over time. As a result, the animals have experienced major changes in their morphology and behavior. Despite these changes, however, the cavefish remain healthy and fit.



The research may provide new clues about the evolutionary consequences of prolonged physical inactivity in humans.&nbsp;



“It’s no surprise that people are moving less and less as technology has advanced,” said Rohner. “With cavefish, we have a unique system where we can study what might happen if people remained couch potatoes over very, very long periods of time.”

"With more than 370,000 miles of coastline on Earth, there are plenty of places where epic waves build up, curl over, and hurtle toward the shore.- much to the thrill of surfers," says NASA. "There are some places where these waves are so magnificent that they can be seen from space."



"With the broad perspective of satellites, we can see how these iconic waves develop into the world’s tallest, longest, fastest, and heaviest."
