Singing to a baby may feel like nothing more than a timeless tradition, yet fresh data now proves just how much those soft tunes matter. Researchers at <a href="https://www.yale.edu/" target="_blank" rel="noreferrer noopener">Yale University</a> ran a four‑week experiment and saw babies’ mood ratings climb when parents were nudged to sing more often.



<h2 class="wp-block-heading" id="h-lullaby-benefits">Lullaby benefits</h2>



Parents have always trusted songs to soothe, and science backs that trust. In a 2021 <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8220405/" target="_blank" rel="noreferrer noopener">study</a>, infants’ heart rates and skin conductance dropped when they heard lullabies in foreign languages. 



Those calming effects appear stronger than speech alone, hinting that melody taps regulatory circuits <a href="https://www.earth.com/news/social-dancing-and-singing-lullabies-to-babies-are-not-innate-human-behaviors/">beyond ordinary talk</a>.



Another experiment showed that seven‑ to ten‑month‑olds listened to singing for about twice as long as speech before fussing. 



Taken together, these findings explain why even sleep‑deprived caregivers keep humming when nothing else works.



<h2 class="wp-block-heading" id="h-cultural-roots-of-singing-to-babies">Cultural roots of singing to babies</h2>



Across time and geography, parents have sung to soothe, bond, and signal safety. 



<a href="https://www.ethnomusicology.org/" target="_blank" rel="noreferrer noopener">Ethnomusicology</a> studies show that infant-directed singing has distinct features, like slower tempo, repetitive structure, and pitch exaggeration, that appear in nearly every society’s lullabies. 



These songs aren't just tradition. They likely emerged because they work. In communities without formal parenting tools or gadgets, music acts as an instinctive caregiving method that bridges generations, languages, and lifestyles. 



Understanding this <a href="https://www.earth.com/news/music-causes-similar-emotional-experiences-and-sensations-in-all-cultures/">global pattern</a> helps explain why singing continues to be a reliable tool in modern households, regardless of background.

<a href="https://www.eunchomusic.com/about-me">Eun Cho</a> of the <a href="https://www.eunchomusic.com/about-me" target="_blank" rel="noreferrer noopener">Yale Child Study Center</a> and colleagues recruited 110 families with babies younger than four months. 



Using ecological momentary assessment, a smartphone survey method that pings parents randomly through the day, they captured real‑time mood snapshots instead of relying on memory.



Half the parents got karaoke‑style videos, songbooks, and weekly prompts; the rest continued usual care. 



Within a week most in the music group were singing in nearly nine out of ten survey windows, and that habit stuck after the prompts stopped.



“Parents intuitively gravitate toward music as a tool for managing infants' emotions, because they quickly learn how effective singing is at calming a fussy baby,” said <a href="https://psychology.fas.harvard.edu/people/samuel-mehr" target="_blank" rel="noreferrer noopener">Samuel Mehr</a>, director of <a href="https://www.themusiclab.org/" target="_blank" rel="noreferrer noopener">The Music Lab</a>. 



Parents were never told when to sing, yet they instinctively reached for music during bouts of fussing. 



Survey data confirmed his point: singing became the only soothing technique that rose significantly during the intervention. Babies whose caregivers sang more showed higher overall mood scores, not just momentary relief.

<a href="https://www.earth.com/news/similar-patterns-music-language-found-across-all-cultures/">Cross‑cultural work</a> finds songs tied to infant care in every documented society, suggesting an evolutionary role. 



Melodies carry repetitive rhythms and exaggerated pitch contours that match babies’ sensitivity to temporal patterns.



These <a href="https://www.earth.com/news/babies-hear-far-more-speech-at-home-than-music/">acoustic cues</a> likely signal safety, driving a physiological downshift: slower heart rate, calmer nervous system, steadier gaze. 



Because the same core features appear in many musical traditions, even unfamiliar songs can have the desired effect.



<h2 class="wp-block-heading" id="h-singing-helps-both-babies-and-parents">Singing helps both babies and parents</h2>



While the Yale trial did not boost caregiver mood in four weeks, other work hints at downstream benefits. 



A 10‑week group‑singing program in Italy eased <a href="https://www.frontiersin.org/journals/medicine/articles/10.3389/fmed.2024.1461965/full" target="_blank" rel="noreferrer noopener">postpartum depression</a> symptoms and was rated feasible for public clinics.



Lower infant distress can also lighten parental stress loads, improving sleep and bonding over time. Researchers plan longer studies to test whether daily singing shifts family health more broadly.



<h2 class="wp-block-heading" id="h-homes-without-music">Homes without music?</h2>



While many families in the Yale study already used music daily, not all households have the same habits. Earlier <a href="https://www.sciencedirect.com/science/article/pii/S0163638324000079" target="_blank" rel="noreferrer noopener">research</a> using all‑day audio recorders found surprisingly little music in many infants’ environments, even when parents assumed they sang often.



This gap means some babies may miss out on the emotional support <a href="https://www.earth.com/news/mothers-can-use-singing-to-engage-with-infants/">singing</a> provides, especially in homes facing stress, poverty, or limited caregiver time. 



Low‑cost tools like the ones used in the study, songbooks, videos, simple reminders, may help close that gap and give all babies the same access to mood‑lifting interaction. 



Even a small boost in daily musical moments could be a game‑changer for the most vulnerable infants.



<h2 class="wp-block-heading" id="h-bringing-music-home">Bringing music home</h2>



No special skill, speaker, or playlist is required. Pick any simple tune, nursery rhyme, folk song, or a chorus you like, and <a href="https://www.earth.com/news/finding-their-voice-how-singing-empowers-children/">sing</a> it at diaper changes, before naps, or in the evening bath. 



Keep the tempo slow, the volume soft, and repeat phrases so your baby learns the pattern. 



Consistency, not perfection, appears to be what a newborn brain craves, and caregivers already hold the most responsive instrument.



Your voice is enough. And for your baby, it might just be the best sound in the world. The science agrees: a few songs a day can go a long way.

Singing to babies significantly improves their mood and overall well-being, study confirms

A new study from the <a href="https://www.upenn.edu/">University of Pennsylvania</a> has found that interference with natural circadian rhythms promotes tumor growth and suppresses the effects of a tumor-fighting drug. The findings highlight the need for “chronotherapy,” which is the delivery of cancer drugs timed to the internal <a href="http://www.earth.com/news/circadian-rhythm-light-melatonin/">circadian rhythm</a>.

In the background of our brain, a 24-hour clock keeps time for changes in our physical and mental cycles in response to environmental cues such as light and darkness. This natural circadian rhythm regulates many important aspects of our lives. 

Disruption of the brain’s circadian clock through sleep disturbances or shift work, for example, is a known risk factor for several types of cancer. While it is known that hormonally-induced circadian disruption promotes tumor growth in animal models, the underlying mechanism has not been clear.

To investigate, the researchers used the hormone dexamethasone to advance daily rhythms in cultured cells. The treatment was found to alter the expression of multiple genes, especially those involved in regulating the cell cycle. 

In particular, circadian rhythm disruption increased the expression of a cell-cycle control protein called cyclin D1. This activated cyclin D-dependent kinase 4/6, a step that ultimately leads to cell division.

Tumor growth is closely tied to cell division, so many cancer treatments aim to inhibit the progression of the cell cycle. The researchers found that the tumor-fighting ability of a drug called PD-0332991, which inhibits CDK4/6 activity, varies according to the time of the day. 

Essentially, the treatment was found to be more effective in the morning than at night. Furthermore, the efficacy of the drug was reduced in mice when their circadian rhythms were disrupted.

“We suggest that chronic disruption of the normal circadian rhythm tips the balance between tumor-suppressive and tumor-progressive gene expression to favor tumor growth,” said study co-author Amita Sehgal. “Better understanding the molecular effects of jet lag, shift work, and other sources of chronic disruption may lead to strategies to minimize the increased cancer risk associated with these behaviors, and to better treatment strategies, including timing delivery of cancer therapy for maximum benefit.”

The study is published in the journal <a href="https://journals.plos.org/plosbiology/">PLOS Biology</a>.

The next time you go in for your annual checkup, you might consider having your <a href="https://www.earth.com/news/smell-mixtures-scents/">sense of smell </a>checked too, as a new study has found surprising links between poor sense of smell and a higher risk of early death.

Although the reasons behind this correlation between sense of smell and increased risk of death remain unknown, researchers from <a href="https://msu.edu/">Michigan State University</a> conducted the first study of its kind to examine how the two are connected.

The study was published in the journal Annals of Internal Medicine, and the results show that older adults who have a poor sense of smell have a nearly 50 percent increased risk of dying within ten years.

“Poor sense of smell becomes more common as people age, and there's a link to a higher risk for death,” said Honglei Chen, an epidemiologist and member of the research team. “Our study is the first to look at the potential reasons why it predicts a higher mortality.”

The researchers reviewed and analyzed data from nearly 2,300 participants aged 71 to 82 who were part of the <a href="https://healthabc.nia.nih.gov/">National Institute on Aging's Health ABC study</a>. Participants were followed for 13 years and the assessment included a smell test of 12 odors.

A poor sense of smell correlated with a 46 percent higher risk of death after 10 years and a 30 percent risk at 13 years.

The researchers accounted for several factors including sex, race, and lifestyle factors but the links stayed consistent.

Surprisingly, participants who were in good health at the start of the ABC study were at a higher risk which indicates that sense of smell should be taken seriously as a predictor of potential health problems.

A reduced sense of smell is an early sign of dementia and Parkinson’s, but these factors were not enough to explain the increased risk of death linked to smell and more research is needed to solve this connection.

“We don't have a reason for more than 70% of the increased risk. We need to find out what happened to these individuals,” said Chen. “It tells us that in older adults, impaired sense of smell has broader implications of health beyond what we have already known. Incorporating a sense of smell screening in routine doctor visits might be a good idea at some point.”

Poor sense of smell linked to higher risk of early death in older adults

The next time you go in for your annual checkup,...

Both drug-induced and spontaneous encounters with a higher power or “God” can be life changing for people both on a spiritual and physical level. 

There have been countless reports of people having deeply religious experiences, some drug-induced through the use of <a href="https://www.earth.com/news/magic-mushrooms-vote-medicinal-benefits/">psychedelics</a> and some spontaneous.

Given the significance that religious experiences and God encounters hold for people, researchers from<a href="https://www.jhu.edu/"> John Hopkins University</a> conducted a study to examine the potential healing properties that these deeply meaningful experiences can have.

The point of the study was not to prove the existence of a God or religion, although more than two-thirds of the survey respondents admitted to changing their atheist beliefs after an encounter. But the main objective was to assess the lasting positive changes attributed to a drug-induced or spontaneous religious experience. 

The study was published in the journal PLOS ONE. 

“Experiences that people describe as encounters with God or a representative of God have been reported for thousands of years, and they likely form the basis of many of the world’s religions,” said Roland Griffiths, the lead researcher of the study. “And although modern Western medicine doesn't typically consider ‘spiritual’ or ‘religious’ experiences as one of the tools in the arsenal against sickness, our findings suggest that these encounters often lead to improvements in mental health.”

The researchers surveyed 4,285 participants worldwide who took part in one of two online surveys after responding to an online advertisement. 

Questions on memorable encounters with the “God of their understanding,” a “higher power,” “ultimate reality” or “an aspect or representative of God, such as an angel,” were included in the survey. 

Participants were also asked about how the experience impacted their lives.

Of the participants, 1,184 reported taking magic mushrooms prior to their encounter. 1,251 took LSD, 606 took DMT, a naturally occurring psychedelic substance, and 435 said they took ayahuasca. 

Overall, regardless of whether the encounter was catalyzed by psychedelics or spontaneous, 75 percent of the participants said their personal religious experience was one of the most meaningful and significant experiences of their lives. 

70 percent of the participants that took psychedelics admitted feeling less afraid of death after their encounter, and the encounter was linked to positive and lasting changes in happiness, wellbeing, and added meaning and purpose to the participant's lives. 

It is important to note that because the study relied on self-reported information, there are many limitations to the research. 

However, the results indicate that deeply religious experiences can have a positive impact on mental health and wellbeing, a fact that deserves further explanation, according to the researchers. 

“Continuing to explore these experiences may provide new insights into religious and spiritual beliefs that have been integral to shaping human culture since time immemorial,” said Griffiths.

A report from the <a href="http://www.oecd.org/">Organization for Economic Co-operation and Development</a> (OECD), a coalition of 36 countries across the globe, has revealed that half of all jobs will be substantially changed by technology within the next two decades. In this time frame, the OECD predicts that 14 percent of jobs will be completely automated, while 32 percent of <a href="http://www.earth.com/news/outsource-jobs-health-risks/">jobs</a> will be significantly different than they are today.


According to the research, the technological transformation of jobs will not necessarily mean that there will be less jobs available, but that new jobs will require updated skills. “The OECD Employment Outlook does not envisage a jobless future. But it does foresee major challenges for the future of work,” explained OECD Secretary-General Angel Gurría.

The number of highly-skilled jobs which require information and communications technology (ICT) experience has increased by 25 percent over the last 20 years. However, only six out of 10 adults currently have ICT training. The OECD says that a robust adult training program is critical to help workers adapt to the changing workforce.

“In all OECD countries, training participation is lowest among those who need it most, including the low-skilled, older adults and non-standard workers,” the coalition states. “A major overhaul of adult learning programs to increase their coverage and promote quality is needed to harness the benefits of the changing world of work. Measures should include removing time and financial constraints to participation in training, making training rights portable, and providing quality information and counseling.”

Some policy makers have even proposed what is known as a Universal Basic Income, which would be given to all citizens, to ease the burden of an automated future. The money would allow workers to seek additional training for new jobs and provide support for those in positions that will become obsolete.

“Adapting and extending social protection is essential to ensure better coverage for workers in non-standard forms of employment,” states OECD. “Non-standard workers are, in some countries, 40-50% less likely to receive any form of income support while out of work than standard employees. Benefit entitlements should be made portable across jobs and targeted social protection measures complemented with more universal and unconditional support.”

“Even with a rapidly changing economy and the forward march of technology, all we need is a plan,” said Gurria. “With the right policies, we can manage these challenges. We face significant transformation, but we have the opportunity and the determination to use this moment and build a future of work that benefits everyone.”

The study is published in the journal <a href="https://ehjournal.biomedcentral.com/">Environmental Health</a>.

Half of all jobs will be transformed by automation, report shows

A report from the Organization for Economic Co-operation and Development...

A recent study of global trends in body-mass index (BMI) has revealed that rates of <a href="http://www.earth.com/news/obesity-related-cancers-young-adults/">obesity</a> are rising faster in rural areas compared to cities. A team led by <a href="https://www.imperial.ac.uk/">Imperial College London</a> analyzed height and weight data for more than 112 million adults across 200 countries between 1985 and 2017.

The study, which involved a network of more than 1,000 researchers, found that more than half of the average increase in BMI was due to gains in rural areas. In some low- and middle-income countries, rural areas contributed more than 80 percent of the BMI increase.

In 1985, urban men and women in over 75 percent of the countries had a higher BMI than those living in rural regions. Over the next three decades, the gap between urban and rural BMI shrank or even reversed in many of the countries.

“The results of this massive global study overturn commonly held perceptions that more people living in cities is the main cause of the global rise in obesity,” said study senior author Professor Majid Ezzati. “This means that we need to rethink how we tackle this global health problem.”

In high-income countries, BMI has been generally higher in rural areas since 1985, especially for women. The researchers said this may be due to disadvantages associated with living outside of cities, including lower income and education, limited availability and higher price of healthy foods, and fewer leisure and sports facilities.

[caption id="attachment_1872363" align="aligncenter" width="650"]<a href="https://www.earth.com/wp-content/uploads/2019/05/obesity-rates.jpeg"><img class="wp-image-1872363" src="https://www.earth.com/wp-content/uploads/2019/05/obesity-rates.jpeg" alt="" width="650" height="322" /></a> A positive number shows a higher urban mean BMI, and a negative number a higher rural mean BMI. Image Credit: Ezzati et al. Nature 2019[/caption]

“Discussions around public health tend to focus more on the negative aspects of living in cities,” said Professor Ezzati. “In fact, cities provide a wealth of opportunities for better nutrition, more physical exercise and recreation, and overall improved health. These things are often harder to find in rural areas.”

At the same time, rural areas in low- and middle-income countries have shifted toward higher incomes, improved infrastructure, and increased car use. While all of these factors lead to numerous health benefits, they also lead to lower energy expenditure and to more spending on food.

“As countries increase in wealth, the challenge for rural populations changes from affording enough to eat, to affording good quality food,” said Professor Ezzati.

The study is published in the journal <a href="https://www.nature.com/">Nature</a>.

Obesity rates are rising faster in rural areas

A recent study of global trends in body-mass index (BMI)...

A new study from the <a href="https://www.escardio.org/">European Society of Cardiology</a> has revealed that people who skip breakfast and eat a late dinner have a more difficult time recovering after a <a href="http://www.earth.com/news/heart-attacks-less-deadly/">heart attack</a>. 

The researchers found that individuals with both of these detrimental eating habits were up to five times more prone to another heart attack, chest pain, or even death within 30 days of being discharged from the hospital after a heart attack. 

The investigation was focused on 113 patients with an average age of 60 who had experienced a particularly serious form of heart attack called ST-segment elevation myocardial infarction (STEMI). Among the study participants, 58 percent skipped breakfast, 51 percent ate late-night dinner, and 41 percent had both habits.


“One in ten patients with STEMI dies within a year, and nutrition is a relatively inexpensive and easy way to improve prognosis,” said study co-author Dr. Marcos Minicucci of <a href="https://en.wikipedia.org/wiki/S%C3%A3o_Paulo_State_University">São Paolo State University</a>.

“It is said that the best way to live is to breakfast like a king. A good breakfast is usually composed of dairy products (fat-free or low fat milk, yogurt and cheese), a carbohydrate (whole wheat bread, bagels, cereals), and whole fruits. It should have 15 to 35% of our total daily calorie intake.”

Dr. Minicucci noted that late-night dinner eating was defined by less than two hours between dinner and bedtime. Previous studies have found that people who miss breakfast and have a late dinner are more likely to have other unhealthy habits as well, such as smoking and low levels of physical activity. 

“Our research shows that the two eating behaviors are independently linked with poorer outcomes after a heart attack, but having a cluster of bad habits will only make things worse,” said Dr. Minicucci. “People who work late may be particularly susceptible to having a late supper and then not being hungry in the morning.”

“We also think that the inflammatory response, oxidative stress, and endothelial function could be involved in the association between unhealthy eating behaviors and cardiovascular outcomes."

Skipping breakfast linked to 87 percent higher risk of heart disease. A new study published by the <a href="https://www.acc.org/">American College of Cardiology</a> is providing new evidence to suggest that <a href="http://www.earth.com/news/skipping-breakfast-cardiovascular-issues/">breakfast</a> really is the most important meal of the day. 

The researchers found that individuals who skipped breakfast on a regular basis were more likely to die from cardiovascular disease. By contrast, those who ate breakfast every day had a substantially reduced risk of death from heart disease.

The experts analyzed data from the National Health and Nutrition Examination Survey, which was conducted from 1988 to 1994, with an average follow-up of 18 years. The researchers had access to relevant information on more than 6,000 participants between the ages of 40 and 75, who had no history of cardiovascular disease or cancer. 

The participants were asked to report how often they ate breakfast, and the possible responses ranged from every day, some days, rarely, or never. Overall, 5.1 percent of the individuals never ate breakfast, 10.9 percent rarely ate breakfast, 25 percent ate breakfast some days, and 59 percent ate breakfast every day.

The study revealed that individuals who never consumed breakfast had an 87 percent higher risk of cardiovascular disease-specific mortality compared to those who consumed breakfast every day. 

According to the researchers, skipping breakfast was found to be associated with changes in appetite and decreased satiety, elevated blood pressure, and harmful changes in lipid levels. The experts also noted that neglecting to eat breakfast appeared to be a behavioral marker for unhealthy lifestyle habits.

The study is published in the <a href="http://www.onlinejacc.org/">Journal of the American College of Cardiology</a>.

According to a new study by the <a href="https://www.sandiego.va.gov/">VA San Diego Healthcare System</a>, prolonged exposure therapy is more effective at treating PTSD than coping skills therapy for patients who also have an alcohol use disorder. The research will provide clinicians with important guidance for helping veterans cope with both <a href="http://www.earth.com/news/transcendental-meditation-ptsd-symptoms/">PTSD</a> and problem drinking.


When the researchers compared patients who were given prolonged exposure treatment with those given coping skills treatment, they found that both methods effectively reduced PTSD symptoms and heavy drinking. However, patients receiving prolonged exposure therapy had significantly lower scores on a measure of PTSD symptoms. 

The study was led by Dr. Sonya Norman, who is a researcher at the San Diego VA, the director of the PTSD Consultation Program for the National Center for PTSD, and a professor of Psychiatry at the University of California San Diego.

“The research is not showing concerns that PTSD patients with alcohol use disorder can't handle exposure to be true,” said Dr. Norman. “The main takeaway of the study for me is that we may be doing a disservice to veterans if we don't offer them the best treatments we have available for PTSD, such as prolonged exposure.”


People suffering from both PTSD and alcohol use disorder tend to have shorter periods of abstinence from drinking and a greater risk of suicide and homelessness. Compared to individuals with just one disorder, these patients also tend to have more legal and psychological problems.

During prolonged exposure therapy, patients gradually confront memories, feelings, and situations related to their trauma. The goal is for them to be able to face these experiences without triggering anxiety and stress.

While previous studies have shown that prolonged exposure therapy is the most effective treatment for PTSD, many therapists do not offer this particular psychotherapy to problem drinkers out of concern that it will cause them to drink more.

However, the results of the new study show that prolonged exposure therapy is more effective at treating PTSD regardless of whether patients also have alcohol use disorder. The researchers concluded that many patients are not getting the best available treatment because of their issues with alcohol. 

“The next stage of this research, is to learn how to make prolonged exposure even more effective for patients with PTSD and alcohol use disorder,” explained Dr. Norman. “We are now conducting a study where we are combining medication to help reduce drinking with prolonged exposure to see if the combination helps patients complete prolonged exposure and benefit even more from the treatment.”

The study is published in the journal <a href="https://jamanetwork.com/journals/jamapsychiatry">JAMA Psychiatry</a>.

Exposure therapy found to effectively treat PTSD, problem drinking

According to a new study by the VA San Diego...

A new study has revealed that the consumption of a Mediterranean diet may help prevent overeating. The research has also produced the first experimental evidence that a <a href="http://www.earth.com/news/mediterranean-diet-sex-life/">Mediterranean diet</a> can protect against obesity and prediabetes compared to a Western diet.

When researchers allowed nonhuman primates to eat as much as they desired, the animals who were on a Mediterranean diet did not eat all of the available food and maintained a healthy weight.

“By comparison, the animals on a Western diet ate far more than they needed and gained weight,” explained study lead author Carol A. Shively, who is a professor of Pathology at the <a href="https://school.wakehealth.edu/">Wake Forest School of Medicine</a>.

According to Professor Shively, this is the first preclinical study to measure the long-term health effects of a Western diet versus a Mediterranean diet under controlled experimental conditions.

Previous studies that were focused on how diet type may influence the number of calories consumed were primarily based on self-reported food intake by humans, which is often unreliable. Similar research was focused on rodents who were given nonhuman-type diets.

For the current study, the diets were formulated to closely represent human diets. The 38-month trial, which involved nearly 40 female primates split into two groups, translated to about nine years for humans.

Protein and fat were derived mostly from animal sources in the Western diet and primarily from plant sources in the Mediterranean diet. Overall, however, the two diets contained comparable proportions of fat, protein, and carbohydrates.

“What we found was that the group on the Mediterranean diet actually ate fewer calories, had lower body weight and had less body fat than those on the Western diet,” said Professor Shively.

The Mediterranean diet not only helped to prevent obesity, but also protected against non-alcoholic fatty liver disease (NAFLD). Obesity is a major cause of NAFLD, which can cause cirrhosis and liver cancer. 

One-third of American adults are expected to have NAFLD by 2030, and it is the fastest growing cause of liver transplants among young adults in the United States.

“Diet composition is a critically important contributor to the U.S. public health, and unfortunately those at the greatest risk for obesity and related costly chronic diseases also have the poorest quality diets,” said Professor Shively.

“The Western diet was developed and promoted by companies who want us to eat their food, so they make it hyper-palatable, meaning it hits all our buttons so we overconsume. Eating a Mediterranean diet should allow people to enjoy their food and not overeat, which is such a problem in this country.”

“We hope our findings will encourage people to eat healthier foods that are also enjoyable, and improve human health.”


The study is published in the journal <a href="https://onlinelibrary.wiley.com/journal/1930739x">Obesity</a>.

Living near protected areas may make people more environmentally conscious. People who live near protected environmental areas (Pas) are more likely to adopt pro-environmental behaviors, support conservation and management, and vote for party candidates who run on pro-environment platforms. 

This is the major takeaway from a new study conducted by the<a href="http://www.cnrs.fr/en/cnrs"> French National Center for Scientific Research</a> and published in the journal Biological Conservation. 

To examine the impact that PAs have on nearby residents, scientists reviewed three key indicators for environmental consciousness. 

The researchers wanted to see what, if any, influence living near a protected area has on a person’s attitudes toward environmentalism and conservation. 

Indicators of environmental consciousness included how much support there was for green candidates in different town elections in France, how much people contributed to ecological conservation funds like the <a href="https://www.worldwildlife.org/">World Wildlife Fund</a> and the <a href="https://www.lpo.fr/">Ligue pour la Protection des Oiseaux</a>, a bird conservation, and lastly how many people participated in a garden birdwatch citizen science initiative coordinated by the <a href="https://www.mnhn.fr/en">Museum National d’Histoire Naturelle</a>. 

These indicators are reliable measures of environmentalism in people, according to the researchers. 

Overall, the researchers found that people were more pro-environment when they lived near PAs. Green candidates performed 31 percent higher near PAs and membership to the bird conservation group was twice as high in towns closer to a PA. Living near protected areas may make people more environmentally conscious 

The researchers also found that the number of retirees in a town was a factor in a population’s environmentalism as retirees showed more interest in the bird watching citizen science program. 

There are several possible reasons for why proximity to PAs correlates with environmental consciousness. 

Living near a wild area may cause people to be more involved in protecting those areas and spur an interest in nature compared to people who live in urban areas. 

PAs directly promote pro-environmentalism through park staff efforts, campaigns, and education outreach opportunities. 

The lack of priority given to <a href="https://www.earth.com/news/trump-mining-boundary-waters/">conservation and environmental protection</a> in some countries could have adverse ripple effects as this study shows, further instilling a dismissive attitude toward conservation.

However, if parks and protected areas keep their protected status, it could raise awareness and promote a sense of environmental stewardship.

You’ll gain more weight if you eat comfort food while also stressed. A team of researchers led by Professor Herbert Herzog, Head of the Eating Disorders laboratory at the <a href="https://www.garvan.org.au/">Garvan Institute of Medical Research</a>, have found that eating a high-calorie diet during a period of stress can result in a person gaining more weight than if they ate that high-calorie diet in a stress-free environment.

"This study [published in <a href="https://www.cell.com/cell-metabolism/home">Cell Metabolism</a>] indicates that we have to be much more conscious about what we're eating when we're stressed, to avoid a faster development of obesity," Professor Herzog said.

Many people seek comfort in calorie-dense foods when in a <a href="http://www.earth.com/news/nature-significantly-reduce-stress-levels/">stressful</a> situation, and the researchers wanted to gain a better understanding of why this happens. To do so, they first studied the emotion-driven part of the brain — the amygdala — within mice. They were then able to target an eating-stimulant molecule called NPY, which the brain produces in response to stress. NPY is also present in human brains.

"Our study showed that when stressed over an extended period and high calorie food was available, mice became obese more quickly than those that consumed the same high fat food in a stress-free environment," said lead author Dr. Kenny Chi Kin Ip. “We discovered that when we switched off the production of NPY in the amygdala, weight gain was reduced. Without NPY, the weight gain on a high-fat diet with stress was the same as weight gain in the stress-free environment.”

“This shows a clear link between stress, obesity and NPY,” Dr. Ip concluded.

To better grasp why NPY is produced under stress, the team looked at the nerve cells in the amygdala that produce the molecule. Each cell has receptors (or, “docking stations”) for insulin, a hormone that controls our food intake.

Normally, insulin is produced after a meal to help cells absorb glucose from the blood and tell hypothalamus in the brain to stop eating. However, under chronic stress, the researchers found that blood insulin levels rise, and when a high-calorie diet is introduced, insulin levels could jump 10 times higher than when the mice were operating in a stress-free environment eating a normal diet.

Prolonged periods of high insulin cause the cell docking stations to become desensitized to insulin, therefore they stop detecting the hormone. The cells then boost their NPY levels, which promotes eating.

"Our findings revealed a vicious cycle, where chronic, high insulin levels driven by stress and a high-calorie diet promoted more and more eating," Professor Herzog explained. "This really reinforced the idea that while it's bad to eat junk food, eating high-calorie foods under stress is a double whammy that drives obesity."

He continued, “We were surprised that insulin had such a significant impact on the amygdala," says Professor Herzog. "It's becoming more and more clear that insulin doesn't only impact peripheral regions of the body, but that it regulates functions in the brain. We're hoping to explore these effects further in future."

One in five say they’ve been harmed by the drinking habits . When enjoyed in moderation and under the appropriate circumstances, alcohol can be a welcome addition to any celebration or moment of relaxation. But it’s no secret that <a href="http://www.earth.com/news/alcohol-consumption-gene-marriage/">alcohol</a> can also be an instigator of more than just a few problems.

A recent study published in the online journal <a href="https://bmjopen.bmj.com/">BMJ Open</a> has found that one in five people in England have been harmed by others’ drinking at some point in the past year. The study surveyed 5,000 adults in England, assessing the extent, type, and frequency of the harms associated with other people’s drinking, who is most likely to be affected, and who or what might be causing it.

The potential harms associated with others’ drinking included actual or threatened physical violence, emotional hurt or neglect, being forced or pressured into sex, having to care for someone whose drinking resulted in illness or disability, and being kept awake at night because of associated noise or disruption. Just over 20% of people said they experienced at least one of these harms. 

Men were more likely to experience violence and aggression that women, while women were about twice as likely to have experienced emotional harm or neglect. Results of the survey showed that the factors associated with experiencing harm were being of younger age (16-24), white British ethnicity, having a disability, and being a hazardous drinker, among others. Hazardous drinkers were more than twice as likely to report harm due to others’ drinking compared to those who didn’t drink as much.

“It is clear that [alcohol-related harm to others] is relatively prevalent and that some individuals experience harm frequently. The most prevalent harms could be considered insignificant, but even apparently minor harms such as sleep disruption can have an impact on health and quality of life, particularly if experienced persistently,” the study’s authors explain. “Policies that focus on alcohol must take into consideration the impact of drinking on those other than the drinker.”

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">

</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.”
