Every morning, millions of people crack an egg and begin their day. Whether poached, scrambled, or sunny side up, eggs have remained a breakfast staple around the globe. Yet, for decades, they’ve also been the subject of dietary controversy. 



Health professionals once warned us to limit our egg intake due to cholesterol concerns. They feared that too many eggs might clog arteries and increase the risk of heart disease. But as science continues to evolve, so do our ideas about food.



A new study from the <a href="https://www.unisa.edu.au" target="_blank" rel="noreferrer noopener">University of South Australia</a> now challenges these long-standing beliefs. The research offers clear evidence that eggs may not deserve their bad reputation. Instead, they could be an unexpected ally in maintaining heart <a href="https://www.earth.com/news/just-one-handful-of-pecan-nuts-each-day-can-lower-cholesterol-heart-health/">health</a> if eaten the right way.



<h2 class="wp-block-heading" id="h-eggs-were-blamed-for-heart-problems">Eggs were blamed for heart problems</h2>



The study’s findings arrive at a crucial time. Cardiovascular disease (CVD) remains the leading cause of death across the globe. Nearly 18 million people die from CVD each year. 



In Australia, one person dies every 12 minutes due to CVD. That is one in four lives lost to heart-related issues. With such staggering statistics, it is essential to understand what truly contributes to heart disease.



For years, experts assumed cholesterol-rich foods like eggs played a direct role in raising LDL cholesterol, often called “bad cholesterol.” 



This assumption led to dietary guidelines that limited egg consumption. But Professor Jon Buckley and his research team wanted to look closer. They suspected that the real story was more complex.



“Eggs have long been unfairly cracked by outdated dietary advice,” Professor Buckley says.



<h2 class="wp-block-heading" id="h-eggs-don-t-raise-bad-cholesterol">Eggs don't raise bad cholesterol</h2>



In what’s being called a world-first study, UniSA researchers set out to separate myth from fact. They explored how dietary cholesterol and saturated fat independently affect LDL cholesterol levels. 



The team designed a controlled diet study where participants consumed two eggs daily. The key twist? The overall <a href="https://www.earth.com/news/the-power-of-fish-oil-in-combating-high-cholesterol/">diet</a> was high in cholesterol but low in saturated fat.



The results were surprising. Eating two eggs a day, within a low saturated fat diet, actually reduced LDL cholesterol levels. That means the cholesterol in eggs did not raise the risk of heart disease. 



In fact, when saturated fat intake stayed low, dietary cholesterol from eggs had little to no negative effect.



“In this study, we separated the effects of cholesterol and saturated fat, finding that high dietary cholesterol from eggs, when eaten as part of a low saturated fat diet, does not raise bad cholesterol levels,” Buckley explains.



<h2 class="wp-block-heading" id="h-a-new-culprit-emerges">A new culprit emerges</h2>



So, if not eggs, what’s really behind elevated cholesterol <a href="https://www.earth.com/news/good-cholesterol-may-increase-the-risk-of-dementia/">levels</a>? The answer lies in saturated fat. This kind of fat is found in processed meats, fatty cuts of red meat, full-fat dairy products, and many baked goods. 



When people eat these foods regularly, LDL cholesterol levels can rise, increasing the risk of heart disease.



Buckley and his team highlight that eggs, although rich in cholesterol, contain very little saturated fat. This balance makes them quite different from other animal-based foods. It also means that we need to reevaluate which foods are the true culprits in heart disease risk.



“Instead, it was the saturated fat that was the real driver of cholesterol elevation,” Buckley says.



<h2 class="wp-block-heading" id="h-eggs-are-fine-but-fatty-sides-are-not">Eggs are fine, but fatty sides are not</h2>



This study changes how we might think about the classic cooked breakfast. It is not the eggs on your plate that should raise <a href="https://www.earth.com/news/eating-salmon-can-help-lower-your-cholesterol/">concern</a>. It is what you pair them with. Greasy bacon, processed sausages, and buttered toast may be the real threat to your heart, not the eggs themselves.



“You could say we’ve delivered hard-boiled evidence in defence of the humble egg,” noted Buckley.



So, the next time you are standing in front of a sizzling pan, think carefully. Eggs can remain on the menu. But you might want to skip that second sausage link or the extra slice of fried bread. The study reminds us that balance is more important than banishment.



<h2 class="wp-block-heading" id="h-eggs-in-a-cholesterol-friendly-diet">Eggs in a cholesterol-friendly diet</h2>



Eggs are not only versatile but also packed with essential nutrients. They contain high-quality protein, vitamins like B12 and D, and healthy fats. 



For people trying to maintain a balanced diet, eggs can offer both nourishment and convenience. The new research finally gives them a fair chance to shine without guilt.



“So, when it comes to a cooked breakfast, it’s not the eggs you need to worry about - it’s the extra serve of bacon or the side of sausage that’s more likely to impact your heart health," said Buckley. 



It is time to let go of outdated advice. Science has turned the tables on cholesterol myths, allowing eggs to reclaim their place on the breakfast table. When part of a low saturated fat diet, eggs do not just taste good, they might actually support your heart.



The study is published in the <a href="https://www.sciencedirect.com/science/article/abs/pii/S0002916525002539?via%3Dihub" target="_blank" rel="noreferrer noopener">American Journal of Clinical Nutrition</a>.

Eggs and cholesterol: A new twist in an old debate

Every morning, millions of people crack an egg and begin their day. Whether poached, scrambled, or sunny side up, eggs have remained a breakfast staple around the globe. Yet, for decades, they’ve also been the subject of dietary controversy. Health professionals once warned us to limit our egg intake due to cholesterol concerns. They feared that too many eggs might clog arteries and increase the risk of heart disease. But as science continues to evolve, so do our ideas about food. A new study from the University...

What do we appreciate from nature? Most people would likely answer the food we eat, water we drink, and air we breathe. But this type of thinking is what has led to the potentially shortsighted idea that nature is solely a source of services or commodities.

In a new publication in the journal <a href="http://www.sciencemag.org/journals">Science</a>, thirty international experts associated with the <a href="https://www.ipbes.net/">Intergovernmental Platform on Biodiversity and Ecosystem Services</a> (IPBES), present a new approach to our thinking. They outline the idea of using all of nature’s contributions to people in order to inform policies and decisions.

“For more than a decade, policies about nature have been dominated by knowledge from the natural sciences and economics,” says Professor Sandra Diaz. “The vibrant research developed from this ‘ecosystem services’ approach - popularized by the landmark 2005 Millennium Ecosystem Assessment - has advanced sustainability, but largely excluded insights and tools from the social sciences, humanities and other key worldviews.”

Diax believes that by broadening our notion of nature’s contributions to our society, we see that culture is the consistent factor linked to people and nature. Thinking in this manner also allows us to recognize other “knowledge systems,” like those of local communities and indigenous peoples.

In both developed and developing countries, people rely on nature’s contributions – whether they’re rich or poor. But in order to ensure that we are using our natural resources sustainably, we need to change the way we value nature. 

“This new inclusive framework demonstrates that while nature provides a bounty of essential goods and services, such as food, flood protection and many more, it also has rich social, cultural, spiritual and religious significance - which needs to be valued in policymaking as well,” says Sir Robert Watson, IPBES Chair and former co-chair of the Millennium Ecosystem Assessment.

One example of this new way of thinking revolves around <a href="https://www.earth.com/news/national-junk-food-tax/">food</a>. Obviously, food comes from nature and food security is an important part of any nation, with policies implemented and contested around the world. But food is also a major factor in cultural identities, art, and basic human festivities. This new approach to thinking would better represent these more abstract concepts.

While this all sounds slightly abstract, one concrete application for this approach is its uptake in large-scale expert assessments and how they are conducted. Overall, the researchers believe it will increase the effectiveness and legitimacy of policies and decisions about nature. “This inclusiveness and equity among knowledge systems and perspectives will not only make assessment processes more legitimate; it will also lead to better policy results because we will be drawing from a much richer and wider information base,” the authors say.

The hunter-gatherer lifestyle is something that the vast majority of us can’t relate to. For most of us, our hunting and gathering happens in the aisles of grocery stores – or at it’s most adventurous, in an apple orchard. This has led to numerous anatomical and physiological changes over the many generations between us and our early ancestors. But hunter-gatherers do still exist on our planet, and they have some special traits.

A new study reported in <a href="http://www.cell.com/current-biology/home">Current Biology</a> details how the Jahai people, a group of hunter-gatherers on the Malay Peninsula, are able to name odors as easily as we name colors, and how this relates to their unique lifestyle.

“There has been a long-standing consensus that ‘smell is the mute sense, the one without words,’ and decades of research with English-speaking participants seemed to confirm this,” says Asifa Majid of <a href="http://www.ru.nl/english/">Radboud University</a> in the Netherlands. “But, the Jahai of the Malay Peninsula are much better at naming odors than their English-speaking peers. This, of course, raises the question of where this difference originates.”

To determine whether it was the Jahai who have this ability to detect odors or whether English speakers are simply incompetent, the researchers analyzed two related, yet previously unstudied, groups of people in the tropical rainforest of the Malay Peninsula. These groups were the hunter-gatherer Semaq Beri and the non-hunter-gatherer Semelai. The Semelai are horticulturists, combining shifting rice cultivation and the collection of forest products for trade.

These other groups live in a similar environment to the Jahai, and speak in closely related languages. But how are they are naming <a href="https://www.earth.com/news/humans-sense-smell-dogs/">odors</a>? 

“If ease of olfactory naming is related to cultural practices, then we would expect the Semaq Beri to behave like the Jahai and name odors as easily as they do colors, whereas the Semelai should pattern differently,” the researchers hypothesized.

They found exactly that. Through testing the color- and odor- naming abilities of 20 Semaq Beri and 21 Semelai people using sixteen odors and twenty color hues, the researchers found that the Semaq Beri and Jahai were extremely similar. However, the Semelai performed just like English speakers, having much more difficulty naming odors.

These findings point towards a downgrading in the importance of smells relative to other senses as a result of cultural adaptation. “Hunter-gatherers’ olfaction is superior, while settled peoples’ olfactory cognition is diminished,” says Majid.

The researchers believe that their results challenge the idea that differences in neuroarchitecture alone are behind differences in olfaction. Instead, cultural variation may play an even more prominent role. The next step for the researchers is to determine whether these groups of people have underlying genetic differences related to sense of smell.

The Environmental Protection Agency (EPA) is discreetly changing its system of approving new chemicals, according to a report from <a href="https://www.nbcnews.com/">NBC News</a>. While the previous safety review process was criticized for being too slow, experts are saying that the new approach will not be as thorough.

In 2016, The Frank R. Lautenberg Chemical Safety for the 21st Century Act was passed, which required the EPA to systematically review the safety of commercial chemicals. But now, former <a href="https://www.earth.com/news/pruitt-clean-power-plan/">EPA</a> officials are claiming that some critical steps of the chemical review process are being eliminated, raising concerns about whether the new approach will effectively protect Americans from exposure to hazardous chemicals.


One of the biggest changes the EPA is making is the elimination of consent orders. This means that manufacturers will no longer have to sign a legal agreement that they will not use the chemicals under certain conditions. Consent orders will now only be given if the EPA believes that the intended use of a chemical poses a public health or environmental risk.

Experts explain that, under the new system, a new commercial chemical may be approved for one purpose and then end up being used later for other manufacturing purposes without a comprehensive review. The modified safety review process undermines the legislation passed with widespread approval by Congress in 2016.

Under the Obama administration, Bob Sussman served as co-chair of the Transition Team for the EPA and then as senior policy counsel to the EPA administrator.

“EPA is explicitly disavowing and downplaying a tool that’s really been a cornerstone of new chemical regulation,” Sussman told NBC News. “We believe EPA is taking a big step backward in the protection of health and the environment without an offsetting benefit.”

As an alternative to consent orders, the EPA will now put their confidence into a measure known as “significant new-use rules” to regulate chemicals that may pose a public risk if used for different purposes. Critics say there is a major difference between the former standards and the use of significant new-use rules, which often do not require testing.  

The 2016 legislation not only gave the EPA the authority to enforce a stricter review of commercial chemicals, but also required the EPA to reevaluate the safety of chemicals already in use by a certain deadline.

“What I’m observing is an effort by the agency and also some in the industry to turn back the clock and behave as though the Lautenberg Act was never passed in the first place,” former EPA official Lynn Goldman told NBC News. “The agency has been granted more authority to do testing, then it put hands in its pockets and said it doesn’t want to use this authority.”

A new study has found that women experience higher levels of brain activity during sexual arousal than men do.

Researchers from <a href="https://www.mcgill.ca/">McGill University in Montreal</a> set out to examine the differences in neurological processing between men and <a href="https://www.earth.com/news/rural-women-sex-younger/">women</a> when sexually aroused.

Their results were published in The Journal of Sexual Medicine. 

The study included 20 men and 20 women ages 18-31, all of whom were heterosexual, able to become aroused by heterosexual porn, and had previously engaged in sex at least once. 

The participants were shown both adult films and clips of the popular TV show Modern Family while undergoing MRI scans. The Modern Family clips were used to show the differences between neural responses to humor and arousal. 

Thermal imaging cameras were placed near the subjects’ genitals which gave the researchers a way to monitor arousal and sexual stimulation. 

While watching both the adult film and TV show, each participant had to press a button on a fiber optic response box that indicated an increase or decrease in sexual arousal. 

After analyzing the MRI scans the researchers found that genital arousal was linked to more changes in brain activity, indicated by blood oxygen level-dependent (BOLD) responses.

“There were no brain regions in men with stronger brain-genital correlations than in women,” the researchers said. “Specific visual features of erotic stimuli could play a stronger role in female sexual arousal responses compared with male responses.”

The use of primates in movies may seem like a fun way to raise awareness and goodwill about the animals, but new research has found it may be doing more harm than good.

More often than not, movies misrepresent how <a href="https://www.earth.com/news/primates-danger-extinction/">primates</a> interact and behave in the wild, and do little to educate audiences on their endangered status.

A new study led by Brooke Aldrich, the trustee of the <a href="http://www.neoprimate.org/">Neotropical Primate Conservation</a> charity,  reveals how portraying primates as pets or sidekicks in movies has many negative consequences. 

In short, using primate actors trivializes important issues including conservation and welfare concerns.

Aldrich and colleagues analyzed two decades worth of English speaking movie trailers from 1993 through 2013, where primates were a part of the film. Some instances of films that feature primates include The Hangover Part 2, Pirates of the Caribbean, and Dunston Checks In. 

Over half of the films analyzed had primates interacting with their cast members and often performing “human” behaviors, like smiling, for much of the trailer. 

While filmgoers may find it entertaining, it goes directly against the natural behaviors of the primates. For example, smiling is often an indicator of submission or fear in many primate species. 

The study also shows that primates in movies can cause ignorance about the endangered status of primates in the world. 

A previous study found that 35% of those surveyed didn’t realize that chimpanzees were endangered because of how often they appeared in film and television. 

The results are troubling because films reach audiences of millions and if they misrepresent the true nature of primates, more of the public become misinformed.

“Far too often, well-meaning, animal-loving people fail to recognize the suffering of wild primates in captivity,” said Aldrich. “Given how often people see images of "smiling" chimps or capuchin monkeys, apparently happy to be wearing a pirate suit or brushing their teeth, it's not surprising. As long as monkeys, apes and other primates continue to be depicted in this way, such misunderstandings are likely to continue.”

New research out of the UK has found that microwaves in the EU emit as much carbon dioxide as nearly 7 million cars.

In the first-ever comprehensive study of the environmental impact of the ultra-popular appliance, the results show that microwaves emit 7.7 million tonnes of <a href="https://www.earth.com/video/oceans-remove-carbon-dioxide/">carbon dioxide</a> each year. This amount is equal to how much carbon is emitted annually by 6.8 million cars in the EU.

The study was conducted by researchers from the <a href="http://www.manchester.ac.uk/">University of Manchester</a>, who also found that microwaves across the EU consume as much electricity as three large power plants do every year. 

For the study, the researchers used life cycle assessment to determine the environmental impacts of microwaves. The life cycle, in this case, includes manufacturing and waste management after the microwaves are thrown out. 

Twelve different environmental factors, such as climate change and ecological toxicity, were taken into consideration when measuring the full ecological impact.

Both Manufacturing and the materials used to make microwaves are a major contributor to their impact, as they contribute more than 20% to the depletion of natural resources and climate change alone. 

In order to reduce the environmental impact, the researchers say that focus should be put on consumer awareness and creating more energy efficient models. Because of the large supply and affordability of appliances, microwaves are thrown out before the end of their lifeline. 

Throwing out appliances like microwaves not only generates tons of waste but also creates toxic waste in the process. 

“Consumers now tend to buy new appliances before the existing ones reach the end of their useful life as electronic goods have become fashionable and 'status' items,” said Dr. Alejandro Gallego-Schmid, the study’s lead author. “As a result, discarded electrical equipment, such as microwaves, is one of the fastest growing waste streams worldwide.”

According to the study, appliance lifespans are getting shorter, which causes consumers to throw them away at an increasing rate. Microwave lifespans are now almost 7 years shorter than they were 20 years ago. 

As more and more people purchase and throw out common household appliances like microwaves, the impact on the environment will increase. The research shows that implementing policies for both manufacturers and consumers is vital to reducing waste, power use, and carbon emissions.

Researchers at the <a href="https://www.uni-mannheim.de/en/">University of Mannheim</a> are reporting that stress can actually be a good thing. The experts are suggesting that you can change your mindset to turn stressful times in the workplace into positive experiences.

Stress is not always bad. In fact, <a href="https://www.earth.com/news/scent-reduce-stress/">stress</a> keeps people safe by alerting them to danger when adrenaline and cortisol are released. On the other hand, persistent stress can end up being detrimental to our health.

According to experts, if we simply change our mindset, stress can be a positive thing. When we view something stressful as an opportunity to learn, we can become more motivated and focused on the challenge at hand. This is a major improvement from feeling that a task is unpleasant and exhausting.

The results first appeared in the <a href="http://www.dailymail.co.uk/health/article-5271783/Stress-GOOD-psychologist-explains.html">Daily Mail</a>.

The researchers monitored 171 employees in fields including education, IT, and health and social care to determine the influence of a positive stress mindset. The study participants reported in a journal three times per day. 

In the morning, the individuals documented their expected workload for the day. After work, the participants described whether they had taken any steps to lighten their load, such as looking at the workday as a learning opportunity. Finally, the respondents reported how well they believed they had performed at work and also how they felt just before bed.

The experts found that employees who had a positive stress mindset were able to approach their workload in a way that helped them to feel energized rather than exhausted by the end of the week. A negative stress mindset, on the other hand, led people to be less proactive and more exhausted.

Dr. Megan Arroll told <a href="http://www.dailymail.co.uk/home/index.html">MailOnline</a>: 

“Stress can be a result of overburdening ourselves so don't feel you need to do everything all the time - prioritize yourself as it's impossible to care for others if you're burnt out. We are often better at showing understanding and compassion to pretty much anyone else but ourselves. So practice being kind to you.”

A team of Japanese researchers has determined that Americans are more passionate toward their significant others than Japanese people. The experts suggest that this is due to the fact that Americans live in a social environment where individuals have the options of both choosing and replacing romantic partners.

A growing collection of studies has found that people in North America are generally more passionate than East Asians, including the Japanese and the Chinese. This seems to contradict the idea that East Asians are more codependent than Americans, who are typically regarded as being individualistic and independent.

While monogamy is a common goal in today's society, long-term relationships are faced with the conflict between maintaining a relationship and looking for a more attractive partner. The research team, which was led by Ph.D. student Junko Yamada and Professor Masaki Yuki of <a href="https://www.global.hokudai.ac.jp/">Hokkaido University</a>, focused the study on the theory that Americans are living with the constant fear of being cheated on or left for someone new due to their greater freedom to choose and replace their partners.

The experts were also working under the assumption that passion will promote the behavior of giving partners more attention and affection, while proactively ignoring any advances from another potential partner in order to give a romantic partner reassurance.

In Japan, however, relationships tend to be more stable and hard to change, and people have less risk and anxiety of being cheated on or being rejected. According to the researchers, this makes passionate behavior less important.

For their investigation, the experts surveyed 154 Americans and 103 Japanese people online. The participants answered questions which were designed to measure how they perceived their romantic relational mobility and the intensity of passion that they felt toward their <a href="https://www.earth.com/news/couples-together-share-microbes/">partners</a>. The individuals were also asked how likely they would be to practice various commitment behaviors when forming a relationship.

The study revealed that Americans were more passionate toward their partners due to higher relational mobility in their society. The research team also found that the more passionate an individual was, the more likely they would be abundantly affectionate and loyal. The findings of this study are important to experts as a guide in understanding interpersonal human emotions.

“For humans, it is imperative to win and keep a good mating partner, which is a basic adaptive issue. Our study showed the importance of considering socio-ecological factors when studying human mating behavior. Also, it suggested you should be more passionate and give your partner special attention when they have more freedom to choose,” said Professor Yuki. “However, further studies involving other nationalities and cultural backgrounds should be conducted before generalizing our results.”

A new study from the <a href="https://www.ugr.es/en/">University of Granada</a> is reporting on the impacts that evictions have on mental health. Researchers from the school's Mind, Brain, and Behaviour Research Centre and the Psychology department have found that around 90 percent of study participants who were evicted from their homes suffered from <a href="https://www.earth.com/news/herbs-treat-anxiety/">anxiety</a> and depression.

The study was focused on 205 individuals from the <a href="http://www.housingrightswatch.org/jurisprudence/stopping-evictions-spain-platform-those-affected-mortgage-brings-resolution-european">Stop Evictions Platform</a> in Granada.Women showed higher levels of anxiety and depression than men, while stress was found to affect both genders equally. Dr. Humbelina Robles Ortega is a professor at the University of Granada and one of the co-authors of the study.

“Without a doubt, one of the most striking pieces of data that we have obtained is the high incidence rate of posttraumatic stress disorder (PTSD) symptoms among individuals going through a dramatic event such as an eviction,” said Professor Ortega.


“Years can elapse between the very beginning of the process, when it becomes difficult to pay the mortgage every month, and the moment when a family is evicted from their home.” The researchers pointed out that this leads to prolonged stress.

“These people must deal with a threatening situation and deep uncertainty when they wake up every morning and when they go to bed every night, which affects their physical and psychological well being,” said the study authors.

PTSD can develop when a person is traumatized by fear, helplessness, and dread.

“We have established that a very high proportion of the participants (72.50% of those interviewed) experience the threat of losing their home in a state of fear, helplessness, and dread,” said Dr. Ortega. 

Women were found to have higher levels of PTSD symptoms in men. Dr. Ortega concluded that the findings of the study have serious implications which “call for urgent measures to be introduced in order to adequately protect the mental health of those affected.”

Furthermore, the authors of the study recommend alternative solutions to the way the final stages of the eviction process is currently handled. 

The study is published in the <a href="https://www.cambridge.org/core/journals/spanish-journal-of-psychology">Spanish Journal of Psychology</a>.

A new study from the University of Granada is reporting...

Babies’ ability to learn new and life-changing skills quickly is extremely important for their overall development. How they are able to do this is a question that has intrigued psychologists for years. According to new research from <a href="http://www.psu.edu/">Penn State University</a>, babies’ brains may have been preparing for these new skills long before they are observed using them.

The study was published in <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1467-8624">Child Development,</a> and supports long-standing but untested beliefs about infant development. Famous child psychologist Jean Piaget previously theorized that young children develop in bursts, rather than consistently over time. Using new modeling methods, <a href="http://www.psu.edu/">Penn State</a> professor of psychology Koraly Perez-Edgar was able to examine how behavioral development is related to growth in brain activity.

In a study involving 28 six-month-old infants over a seven-month period, the researchers had the subjects participate in a cognitive “a-not-b” task that measured their understanding of object permanence. This task involved hiding a toy in front of the infant and seeing if they were able to retrieve it.

“How babies perform in this task tells us a lot about their development because it's a coordination of multiple skills,” says Leigha MacNeill, a graduate student in psychology at <a href="http://www.psu.edu/">Penn State</a>. “They have to remember where the ball was moved, which is working memory. They have to know an object exists even though it’s out of sight, and they need to track objects moving in space from one place to another. All of this also required them to pay attention. So there’s a lot going on.”

Along with this task, the infants’ EEG was measured on each visit – with electrodes measuring electrical activity in different regions of the <a href="https://www.earth.com/news/exercise-brain-major-boost/">brain</a>. Data analysis showed that an infant’s performance on the a-not-b task developed in bursts, usually with big spikes around seven and eleven months. However, results showed that EEG power grew steadily throughout the seven months.

“Psychologists have been suggesting that while on the surface development looks like these quick bursts, underneath there may be very continuous, slowly developing mechanisms that one day look like they popped out of nowhere,” Perez-Edgar explains. “Like with kids learning to talk, it looks like they learn all these words overnight, but they’ve been listening and thinking and processing for a long time.”

Along with studying infants’ behavioral development, the study served to observe what is also happening in their brains during this important growth period.

Among the many disastrous consequences that could arise if climate change continues at its current rate, a new study from the <a href="https://www.umich.edu/">University of Michigan</a> reveals that an especially worrisome impact may be on the horizon; the disappearance of our natural sources of maple syrup.

<a href="https://www.earth.com/plants/hybrid-sugar-maple-acer-leucoderme-saccharum-2/">Sugar maples</a> are known for their beautiful fall foliage, as well as being our main source of maple syrup. They also happen to be the dominant tree species in the northern hardwood forests of eastern North America, including in the Great Lakes region. Researchers have recently found that with the forecasts of warmer temperatures and increased likelihood of summer drought in the Upper Great Lakes region, the sugar maples and other trees in that area will be put under a lot of additional stress.

On the flip side, forests around the world will be exposed to rising levels of nitrogen compounds generated by cars, power plants, factories, agriculture, and other human sources. While it’s considered a pollutant, these nitrogen compounds actually have a fertilizing effect on trees, and help promote growth. For years, climate scientists and forest ecologists have wondered whether the fertilizing effects of human-derived nitrogen would be enough to offset the additional stresses of a warmer, drier climate. Previous studies have produced contradictory results.

This new study, published in the journal <a href="http://esajournals.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1939-9170/">Ecology</a>, uses 20 years of data from four forest sites in both of Michigan’s peninsulas, and ultimately finds that nitrogen from human activities “will not fully compensate for the negative effects of growing under the drier forecasted climates.” As climate change marches on, the authors state that residents of the state should see a decrease in growth of sugar maples. Additionally, it appears that if the more extreme climate predictions hold true, sugar maples will eventually disappear from Michigan’s Lower Peninsula entirely.

“Under extreme climate scenarios, the increase in nitrogen won’t be able to compensate for decreased growth of sugar maples due to lack of water,” says Inés Ibáñez, an associate professor and forest ecologist at the University of Michigan.

Losing these trees would likely be a positive feedback loop, as the world’s forests remove about one-quarter of the carbon dioxide emitted into the atmosphere by the burning of fossil fuels. Fewer trees means more carbon dioxide in the atmosphere, further exacerbating the greenhouse gas problem. 

“That’s why these questions about forest growth are so important,” says Donald Zak, a professor at the University of Michigan. “And the only way to get some of the answers is through the type of long-term ecological research used in this study.”

For their study, the researchers analyzed the combined effects of soil moisture, summer temperature, and nitrogen deposition on the growth of sugar maples from four different sites in Michigan. This encompassed records from more than one thousand trees over a period of roughly 20 years.

Are you guilty of micro-cheating? According to psychologist Martin Graff, <a href="https://www.earth.com/news/social-media-helping-communities-manage-fires/">social media</a> is changing the nature of relationships, and our actions online can be just as damaging as having a physical affair. 

Micro-cheating is a relatively recent concept and attempts to define the lines between being casual and friendly online and pursuing outside romantic interests while in a relationship. 

Examples of micro-cheating include checking up an ex-partner’s Facebook profile, adding them on Snapchat or Instagram, messaging them without your partner’s knowledge, or showing too much interest on social media.

“In terms of the history of human communication and relationships this is all brand new,” Graff told <a href="http://www.telegraph.co.uk/news/2018/01/15/micro-cheating-social-media-tearing-couples-apart-scientists/">The Telegraph.</a> “Social media interactions have an inherent ambiguity. Is sending a heart in a Facebook message being unfaithful? Or is it micro-cheating?”

Connecting through social media has never been easier and with the wide range of dating apps available today, the digital age has had a deep and lasting impact on dating and meeting people. 

Micro-cheating is more about being secretive about your online presence than liking someone’s post, although Graff does mention that liking and commenting could affect your relationship. 

For example, putting someone in your phone under a different name or hiding your communication with someone via social media may fall under micro-cheating. 

“Secrecy or covert communications are often, but not always, a sign of micro-cheating,” Graff told <a href="http://www.telegraph.co.uk/news/2018/01/15/micro-cheating-social-media-tearing-couples-apart-scientists/">The Telegraph</a>. 

Critics of the term, however, are not convinced. Twitter has sparked much debate on the subject, with some going as far as to say that being wary of who you connect with online constitutes a controlling relationship rather than secretive flirting.

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.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</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">

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.
