In the face of a rapidly globalizing world, the ever-increasing numbers around one of the most prevalent metabolic disorders are alarming. By 2022, the rate of adults worldwide living with either type 1 or type 2 diabetes had shockingly doubled compared to cases in 1990 - reaching a daunting 800 million.



An analysis from The Lancet reveals that about 445 million adults are currently living with diabetes that has not been adequately treated. 



<h2 class="wp-block-heading" id="h-increasing-rate-of-diabetes">Increasing rate of diabetes</h2>



The data presents a startling revelation - India bears the brunt of this health crisis, hosting over a fourth of the world’s <a href="https://www.earth.com/news/type-2-diabetes-heightens-alzheimers-risk/" target="_blank" rel="noreferrer noopener">diabetic adults</a>.



A total of 212 million individuals, trailed by China's 148 million, are combating diabetes across India. This escalating issue is also prevalent in the United States, Pakistan, Indonesia, and Brazil.



Although this study did not distinguish between type 1 and type 2 diabetes in adults, it's widely accepted that the majority of these cases are attributed to type 2 diabetes.



<h2 class="wp-block-heading" id="h-inequalities-in-healthcare">Inequalities in healthcare</h2>



Professor Majid Ezzati of Imperial College London expressed serious concerns about global inequalities in diabetes treatment.



"Our study highlights widening global inequalities in diabetes, with treatment rates stagnating in many low- and middle-income countries where numbers of adults with <a href="https://www.earth.com/news/diabetes-drugs-may-protect-against-dementia/" target="_blank" rel="noreferrer noopener">diabetes</a> are drastically increasing," noted Ezzati.



"This is especially concerning as people with diabetes tend to be younger in low-income countries and, in the absence of effective treatment, are at risk of life-long complications - including amputation, heart disease, kidney damage or vision loss - or in some cases, premature death."



<h2 class="wp-block-heading" id="h-diabetes-rates-an-upward-spiral">Diabetes rates: An upward spiral</h2>



Thanks to the collaborative efforts of the NCD Risk Factor Collaboration and the World Health Organization, we now have a comprehensive analysis of global diabetes rates and treatment. 



This study, which included data from over 140 million individuals aged 18 years and older from various countries, has revealed deeply unsettling truths.



The numbers are a bitter pill to swallow. Since 1990, diabetes rates have doubled for both men and women (rising from 6.8% to 14.3% and from 6.9% to 13.9%, respectively). 



This translates to around 828 million adults living with diabetes in 2022 - a drastic increase from nearly 198 million in 1990.



<h2 class="wp-block-heading" id="h-disparities-across-the-globe">Disparities across the globe</h2>



Not all nations are equal when it comes to <a href="https://www.earth.com/news/deadly-snail-venom-possible-key-to-improving-diabetes-medicine/" target="_blank" rel="noreferrer noopener">diabetes</a> rates. Between 1990 and 2022, low- and middle-income countries (LMICs) saw the biggest increases. 



In contrast, several high-income countries, such as Japan, Canada, and parts of Western Europe, observed no change or only minor decreases in diabetes rates.



In 2022, the prevalence of diabetes was particularly high in the Pacific island nations, the Caribbean, Middle East and North Africa, Pakistan, and Malaysia. On a brighter note, Western Europe, East Africa, Japan, and Canada reported the lowest rates.



Obesity and poor diets have largely fueled the surge in Type 2 diabetes. Areas where obesity is prevalent, or has dramatically increased, faced higher diabetes rates between 1990 to 2022.



<h2 class="wp-block-heading" id="h-addressing-the-global-diabetes-rate">Addressing the global diabetes rate</h2>



Dr. Ranjit Mohan Anjana, an expert at the Madras Diabetes Research Foundation in India, emphasized the need for diabetes prevention through healthier diets, exercise, and strong health policies, specifically in economically disadvantaged regions.



As of 2022, three out of five adults aged 30 years and older with diabetes - and total of 445 million individuals - did not receive adequate medication. The discrepancy in treatment coverage among nations is striking, with Belgium maintaining the highest rates.



<h2 class="wp-block-heading" id="h-coverage-for-diabetes-treatment">Coverage for diabetes treatment </h2>



Despite the swelling diabetic populations, the coverage for diabetes treatment in many LMICs remains low. It’s troubling to note that over 90% of people were untreated in 1990, a figure that has not changed substantially even in 2022.



“Our findings suggest there is an increasing share of people with diabetes, especially with untreated diabetes, living in low- and middle-income countries," said Professor Jean Claude Mbanya, <a href="https://uy1.uninet.cm" target="_blank" rel="noreferrer noopener">University of Yaoundé 1</a>, Cameroon. 



"In 2022, only 5-10% of adults with diabetes in some sub-Saharan Africa countries received treatment for <a href="https://www.earth.com/news/insufficient-sleep-increases-diabetes-risk-in-women/" target="_blank" rel="noreferrer noopener">diabetes</a>, leaving a huge number at risk of the serious health complications.”

Musical training can improve attention and working <a href="http://www.earth.com/news/writing-by-hand-boosts-learning-and-memory/">memory</a> in children, as well as their overall quality of life, according to a new study led by Dr. Leonie Kausel. The researchers found that musically trained children have greater activation in brain regions related to attention control and auditory encoding, and greater executive skills associated with reading, resilience, and creativity.

Dr. Kausel is a violinist and neuroscientist at the <a href="https://www.uc.cl/en">Pontifical Catholic University of Chile</a> and the Universidad del Desarrollo Chile. Her team tested attention and working memory among 40 children between 10 and 13 years old. Half of the children had been trained to play an instrument for at least two years, while the other half had no musical training.

As the study participants performed an attention and working memory task, their brain activity was monitored with functional magnetic resonance imaging (fMRI), which detects small changes in blood flow within the brain. 

"Our most important finding is that two different mechanisms seem to underlie the better performance of musically trained children in the attention and WM memory task," said Dr. Kausel. "One that supports more domain-general attention mechanisms and another that supports more domain-specific auditory encoding mechanisms."

The "domain" refers to how sensory information such as heat, sound, or light is encoded by the brain, while the "mechanisms" are the neurochemical processes that occur.

Brain regions that were found to be more active in musically trained children include the inferior frontal gyrus and the supramarginal gyrus in the front and center-front of the brain, which are both part of a working memory system involved in auditory processing, establishing auditory-motor connections, and verbal auditory working memory. 

"The next step of the project is to establish the causality of the mechanisms we found for improving attention and working memory," said Dr. Kausel. "We also aim to make a longitudinal study on musical training with children, evaluating attention and working memory, and the possibility to evaluate a musical training intervention on ADHD children."

Dr. Kausel recommends signing children up for music classes, but not simply for the purpose of improving their memory and attention skills. "I think parents should not only enroll their children because they expect that this will help them boost their cognitive functions, but because it is also an activity that, even when very demanding, will provide them with joy and the possibility to learn a universal language."

The study is published in the journal <a href="https://www.frontiersin.org/journals/neuroscience">Frontiers in Neuroscience</a>.

Some <a href="http://www.earth.com/news/friendship-jealousy-can-actually-create-a-happy-ending/">friends</a> make us feel more supported than others, and this may depend on how well they fit into our social network. Researchers have found that people perceive the most support from friends and family members who are also linked to each other socially. 

Study lead author David Lee is an assistant professor of Communication at <a href="https://www.osu.edu/">The Ohio State University</a>. He said the findings suggest that having a network of people to lean on is only part of what makes social support so beneficial to us.

"The more cohesive, the more dense this network you have, the more you feel you can rely on them for support," said Professor Lee. "It matters if your friends can depend on each other, just like you depend on them."

For the investigation, the researchers conducted two online surveys. In the first study, 339 participants were asked to list eight people they felt supported by in the last six months. The lists were found to contain mostly friends and family members, but also included co-workers, romantic partners, classmates, and roommates. 

The participants rated on a scale of 1 to 7 how much support they received from each person. They were also asked to rate the closeness between each possible pair of their eight supporters, with responses ranging from "they don't know each other" to "extremely close."

The researchers used the data to calculate the density of each participant's network - the closer and more interconnected the friends and family, the denser the network. The results showed that individuals with denser networks reported receiving the most support. 

"We found that our support networks are more than the sum of their parts," said study co-author Professor Joseph Bayer. "People who feel they have more social support in their lives may be focusing more on the collective support they feel from being part of a strong, cohesive group. It's having a real crew, as opposed to just having a set of friends."

A second survey revealed that when participants had an emergency situation and needed someone to lean on, they expected to receive more support from an interconnected group of friends and family than from an unconnected group of friends. 

The researchers said the results show that it is not just the number of friends and family you have in your network that is important.

"You can have two friends who are both very supportive of you, but if they are both friends with each other, that makes you feel even more supported."

"Focus on those friends who are connected to each other," said Professor Bayer. "That's where we really perceive the most support."

The study is published in the journal <a href="https://journals.sagepub.com/home/spq">Social Psychology Quarterly</a>.

An eco-friendly shift in American diets could reduce the environmental impacts of <a href="http://www.earth.com/news/experts-work-to-take-threatened-species-off-the-seafood-menu/">food</a> production and consumption by up to 38 percent, according to a new study from the <a href="https://www.uic.edu/">University of Illinois Chicago</a> Institute for Environmental Science and Policy.

"What we eat has an impact on the environment through the land used to grow food, net greenhouse gases released by producing food, and water use," said study lead author Joe Bozeman. "By following guidelines developed with human health and the environment in mind, we can help reduce the environmental impact of food production."

The research was focused on what dietary changes would be necessary among Americans in order to adhere to the healthy targets set by the EAT-Lancet Commission, which represent the first-ever global dietary guidelines. 

The EAT-Lancet recommendations were established in 2019 to help reduce the environmental degradation that will be caused by food production for an estimated global population of 10 billion people by the year 2050.

In a previous study, the researchers analyzed data from the U.S. Environmental Protection Agency's What We Eat in America Food Commodity Intake Database and from the National Health and Nutrition Examination Survey. The team also collected information on the environmental impact of specific foods. 

The study revealed that meat and refined sugar are among foods with the highest negative impact, while vegetables, fish and nuts have much lower impacts.

"We found that shifting to increased vegetable and nuts intake while decreasing red meat and added sugars consumption would help Americans meet EAT-Lancet criteria and reduce environmental degradation between 28% and 38% compared to current levels," said Bozeman. "At the same time, health outcomes would improve, so following these global recommendations would result in a win-win for the environment and human health."

According to Bozeman, different populations would have to make different changes based on their current dietary patterns. For example, black people could meet the EAT-Lancet targets by eating more vegetables and nuts while consuming less red meat, chicken, and added sugars. White people would need to shift their consumption to include less red meat and added sugars, but more nuts.

The findings show that meeting all criteria would significantly decrease environmental degradation in land, greenhouse gases and water.

"Our results provide foundational information that can inform the development of culturally-tailored dietary intervention strategies that consider the implications for human and environmental health," said study co-author Professor Sparkle Springfield.

"However, there is still a need to address the structural and social determinants of diet outcomes, particularly in African American and Latinx populations, in order to promote health equity."

The study is published in the journal <a href="https://home.liebertpub.com/publications/environmental-justice/259/overview">Environmental Justice</a>.

In a new study from <a href="https://www.baylor.edu/">Baylor University</a>, researchers used smartphone surveys to explore the connection between daily spiritual experiences and overall <a href="http://www.earth.com/news/experiencing-awe-in-nature-has-a-powerful-effect-on-emotional-well-being/">well-being</a>.  The experts found that the positive impacts of spirituality on personal satisfaction are long-lasting. 

The team collaborated with researchers at Harvard University to analyze nationwide data, which was collected from volunteers who participated in smartphone check-ins twice a day for two weeks. The study is significant because it evaluates the effects of spiritual experiences over 14 days rather than only one or two points in time, noted the researchers.

Study co-author Dr. Matt Bradshaw is a research professor of Sociology at Baylor University Institute for Studies of Religion (ISR).

"This study is unique because it examines daily spiritual experiences - such as feeling God's presence, finding strength in religion or spirituality, and feeling inner peace and harmony - as both stable traits and as states that fluctuate," said Dr. Bradshaw. 

"Because surveys usually capture only one or two points in time, researchers often have to assume that associations between spirituality and positive emotions capture stable traits in respondents rather than momentary states of mind."

"But these findings suggest that stable, consistent spiritual experiences as well as short-term periodic ones both serve as resources to promote human flourishing and help individuals cope with stressful conditions."

Study lead author Dr. Blake Victor Kent is a research fellow at Harvard Medical School/Massachusetts General Hospital.

"The prevalence of smartphones makes this sort of 'experience sampling' study doable on a much larger scale than in the past, when pagers or palm pilots were used to trigger data collection," said Dr. Kent.

The research was focused on data from SoulPulse, a project designed to study religion, spirituality, and mental and physical well-being. The program involved nearly 2,800 Americans who learned about the study through national media such as the Associated Press.

According to Dr. Kent, daily spiritual experiences are measured as one of two types. Theistic spiritual experiences examine the degree to which God is experienced as present, available, and active in the individual's life using six questions: "I feel God's presence," "I find strength and comfort in my religion or spirituality," "I feel God's love for me directly or through others," "I desire to be closer to God or in union with the divine," "I feel guided by God in the midst of daily activities" and "I feel close to God."

Non-theistic spiritual experiences include transcendent feelings that are not specifically connected to God using three questions: "I feel a deep inner peace or harmony," "I am spiritually touched by the beauty of creation" and "I feel thankful for my blessings."

To keep the daily surveys short and engaging, 10 to 15 items were selected and appeared with varying frequency. These topics were designed to assess depressive symptoms or positive emotions using statements such as "I feel downhearted and blue," "I feel that life is meaningless," "I am unable to become enthusiastic about anything," "I am feeling happy," "I am feeling that I have a warm and trusting relationship with others" and "I have something important to contribute to society."

The participants also reported on whether they had experienced a stressful situation such as an argument with a loved one, illness, job stress, financial problems, or tragedy since their last check-in.

"The findings indicate, as you would expect, that the wear and tear of daily stressors are associated with increased depressive symptoms and lower levels of flourishing," said Dr. Kent. 

"What this study really contributes is that daily spiritual experiences play an important role as well. Essentially, if you take two people who have equal levels of stress, the one with more spiritual experiences will be less likely to report depressive symptoms and more likely to indicate feelings of flourishing. That's a comparison between two people.

"But what about one person? The unique thing about this study is we are able to show that when someone's spiritual experiences vary day to day, the 'above average' days of spiritual experience are associated with better mental well-being than the 'below average' days."

The study is published in <a href="https://www.tandfonline.com/toc/hjpr20/current">The International Journal for the Psychology of Religion</a>.

National guidelines should be established to make sure that <a href="http://www.earth.com/news/children-of-divorced-parents-have-less-of-the-love-hormone-oxytocin/">children</a> continue to receive traditional handwriting training, according to a study led by Professor Audrey van der Meer of <a href="https://www.ntnu.edu/">NTNU</a>. The research confirms the findings of previous studies that both children and adults learn and commit more to memory when writing by hand versus using a keyboard.

The study is the first of its kind to evaluate the benefits of handwriting among children. The researchers used an EEG to track and record the brain wave activity of the participants, who wore a hood with over 250 electrodes attached. When the brain is active, electrical impulses can be detected by sensors in the electrodes. 

The experts found that the brain was far more active when the volunteers were writing by hand compared to when they were typing on a keyboard.

"The use of pen and paper gives the brain more 'hooks' to hang your memories on. Writing by hand creates much more activity in the sensorimotor parts of the brain," explained Professor Van der Meer. 

"A lot of senses are activated by pressing the pen on paper, seeing the letters you write and hearing the sound you make while writing. These sense experiences create contact between different parts of the brain and open the brain up for learning. We both learn better and remember better."

According to Professor Van der Meer, the findings emphasize the importance of children being challenged to draw and write at an early age, especially at school. She believes that there are many positive aspects of digital learning, but urges that handwriting training must be kept in schools as well. 

"Given the development of the last several years, we risk having one or more generations lose the ability to write by hand. Our research and that of others show that this would be a very unfortunate consequence."

"Some schools in Norway have become completely digital and skip handwriting training altogether. Finnish schools are even more digitized than in Norway. Very few schools offer any handwriting training at all."

Many teachers have argued that keyboards create less frustration for children, and that students are more motivated to write because they experience greater mastery with a keyboard.

"Learning to write by hand is a bit slower process, but it's important for children to go through the tiring phase of learning to write by hand. The intricate hand movements and the shaping of letters are beneficial in several ways. If you use a keyboard, you use the same movement for each letter. Writing by hand requires control of your fine motor skills and senses. It's important to put the brain in a learning state as often as possible. I would use a keyboard to write an essay, but I'd take notes by hand during a lecture," said Professor Van der Meer.

"The brain has evolved over thousands of years. It has evolved to be able to take action and navigate appropriate behaviour. In order for the brain to develop in the best possible way, we need to use it for what it's best at. We need to live an authentic life. We have to use all our senses, be outside, experience all kinds of weather and meet other people. If we don't challenge our brain, it can't reach its full potential. And that can impact school performance."

Throughout our lives, we are constantly making random choices that shape our personal <a href="http://www.earth.com/news/mating-routines-birds-paradise/">preferences</a>, like when we decide which bottle of shampoo or pair of jeans to buy. As a result, we become unconsciously biased against the things that we do not choose - even when the options are essentially the same. 

In a new study from <a href="https://www.jhu.edu/">Johns Hopkins University</a>, experts have discovered that humans begin to develop arbitrary preferences and biases in the earliest phase of life. The research has revealed that when babies choose a particular toy, they also commit to disliking the other options. 

"The question of how people’s preferences are shaped by their choices has generated decades of research," wrote the study authors. "In a classic example, work on cognitive dissonance has found that observers who must choose between two equally attractive options subsequently avoid the unchosen option, suggesting that not choosing the item led them to like it less." 

"However, almost all of the research on such choice-induced preference focuses on adults, leaving open the question of how much experience is necessary for its emergence."

The discovery that babies engage in developing unconscious biases suggests that this way of justifying choice is intuitive and a basic aspect of the human experience.

"The act of making a choice changes how we feel about our options," said study co-author Alex Silver. "Even infants who are really just at the start of making choices for themselves have this bias."

The researchers explained that people assume they choose the things they like, but research suggests that the opposite is sometimes true. We often like things simply based on random choices, and dislike the things that we do not choose.

"I chose this, so I must like it. I didn't choose this other thing, so it must not be so good. Adults make these inferences unconsciously," said study co-author Lisa Feigenson. "We justify our choice after the fact."

But at what point in our lives do we begin to shape our preferences through random choices? To investigate, the team focused on babies, who do not have very many decisions to make.

Babies between the ages of 10 and 20 months were presented with two equally bright and colorful soft blocks. The researchers strategically placed the blocks far apart, so the babies had to crawl to one or the other.

Once the baby selected one of the blocks, it was taken away and replaced with a new option. This gave the infants the option of choosing the toy they did not play with the first time or the new toy.

"The babies reliably chose to play with the new object rather than the one they had previously not chosen, as if they were saying, 'Hmm, I didn't choose that object last time, I guess I didn't like it very much,'" said Feigenson. "That is the core phenomenon. Adults will like less the thing they didn't choose, even if they had no real preference in the first place. And babies, just the same, dis-prefer the unchosen object."

When the researchers selected a toy for the baby, they no longer showed a strong preference for a specific toy. If you take the element of choice away, the phenomenon goes away, said Feigenson.

"They are really not choosing based on novelty or intrinsic preference," said Silver. "I think it's really surprising. We wouldn't expect infants to be making such methodical choices."

The researchers will continue to study the evolution of random choices in babies by analyzing how they handle having too many options to choose from at once, or "choice overload." 

The study is published in the journal <a href="https://journals.sagepub.com/home/pss">Psychological Science</a>.

A new study from the <a href="https://www.bath.ac.uk/">University of Bath</a> suggests that drinking coffee first thing in the morning on an empty stomach can interfere with the body's <a href="http://www.earth.com/news/teenage-alcohol-consumption-metabolism/">metabolism</a>. The experts have found that coffee can limit your ability to tolerate the sugar in your breakfast.

A team of researchers in the University's Centre for Nutrition, Exercise &amp; Metabolism investigated the effects of disrupted sleep and morning coffee across a range of different metabolic markers. The results suggest that while one night of poor sleep has limited impact on our metabolism, a strong coffee the next morning may interfere with the body's control over blood glucose.

Keeping our blood sugar levels within a safe range is important for reducing the risk of chronic conditions such as diabetes and heart disease. According to the experts, the findings could have "far-reaching" health implications, especially considering the global popularity of coffee.

Coffee is currently the most popular drink in the world, with around two billion cups consumed every day. 

"We know that nearly half of us will wake in the morning and, before doing anything else, drink coffee - intuitively the more tired we feel, the stronger the coffee," said Professor James Betts. "This study is important and has far-reaching health implications as up until now we have had limited knowledge about what this is doing to our bodies, in particular for our metabolic and blood sugar control."

"Put simply, our blood sugar control is impaired when the first thing our bodies come into contact with is coffee especially after a night of disrupted sleep. We might improve this by eating first and then drinking coffee later if we feel we still feel the need it. Knowing this can have important health benefits for us all."

The study was focused on 29 healthy men and women who were assigned three different overnight tasks in a random order. 

Under one condition, participants were instructed to get a normal night's sleep and were asked to consume a sugary drink upon waking in the morning. On a separate occasion, the volunteers had their sleep disrupted every hour for a few minutes at a time, followed by the same sugary drink.

Under the third condition, participants experienced the same sleep disruption followed by a strong black coffee 30 minutes before consuming a sugary drink.

For each trial, blood samples were collected from each volunteer following the glucose drink- which had about the same amount of calories as a typical breakfast. 

&nbsp;

The study revealed that one night of disrupted sleep did not worsen the participants' blood glucose responses at breakfast when compared to a normal night's sleep. However, strong black coffee consumed before breakfast substantially increased the blood glucose response to breakfast by around 50 percent.

While a growing collection of research has linked coffee to substantial health benefits, there are also previous studies which demonstrated that caffeine has the potential to cause insulin resistance. 

"These results show that one night of disrupted sleep alone did not worsen participants' blood glucose/insulin response to the sugary drink compared to a normal night of sleep which will be reassuring to many of us," said study lead author Harry Smith.

"However, starting a day after a poor night's sleep with a strong coffee did have a negative effect on glucose metabolism by around 50%.

"As such, individuals should try to balance the potential stimulating benefits of caffeinated coffee in the morning with the potential for higher blood glucose levels and it may be better to consume coffee following breakfast rather than before."

"There is a lot more we need to learn about the effects of sleep on our metabolism, such as how much sleep disruption is necessary to impair our metabolism and what some of the longer-term implications of this are, as well as how exercise, for instance, could help to counter some of this."

The study is published in the <a href="https://www.cambridge.org/core/journals/british-journal-of-nutrition">British Journal of Nutrition</a>.

Chronic pain can be reduced by practicing yoga and meditation, according to a new study from the <a href="https://osteopathic.org/">American Osteopathic Association</a>. Individuals who were trained in mindfulness-based <a href="http://www.earth.com/news/pet-owners-felt-less-lonely-and-stressed-during-covid-19-lockdown/">stress</a> reduction (MBSR) reported significantly lower levels of pain, depression, and disability.

An estimated 100 million people are affected by chronic pain in the United States alone, and the associated medical costs are estimated at $635 billion a year.

For the study, members of a semi-rural community in Oregon were trained in mindfulness meditation and mindful hatha yoga over the course of eight weeks. 

"Many people have lost hope because, in most cases, chronic pain will never fully resolve," said Dr. Cynthia Marske. "However, mindful yoga and meditation can help improve the structure and function of the body, which supports the process of healing."

Dr. Marske explained that healing and curing are inherently different. "Curing means eliminating disease, while healing refers to becoming more whole. With chronic pain, healing involves learning to live with a level of pain this is manageable. For this, yoga and meditation can be very beneficial."

The training led to significant improvement in the participants' perception of pain, mood, and functional capacity. Nearly 90 percent of the volunteers reported that the program helped them find ways to better cope with their pain.

Mindful meditation and yoga was also effective in reducing depression. Based on the Patient Health Questionnaire (PHQ-9), a standard measure of depression, the average symptoms dropped by 3.7 points on a 27-point scale. 

"Chronic pain often goes hand-in-hand with depression. Mindfulness-based meditation and yoga can help restore both a patient's mental and physical health and can be effective alone or in combination with other treatments such as therapy and medication," said Dr. Marske.

"The bottom line is that patients are seeking new ways to cope with chronic pain and effective non-pharmaceutical treatments are available. Our findings show meditation and yoga can be a viable option for people seeking relief from chronic pain."

The study is published in the <a href="https://jaoa.org/">Journal of the American Osteopathic Association</a>.

A new study from <a href="https://ucsd.edu/">UC San Diego</a> is shedding some positive light on the loneliness epidemic, finding that wisdom can ward off the negative health impacts of social isolation. The researchers found that adults from San Diego all the way to Cilento, Italy are protected from <a href="http://www.earth.com/news/loneliness-makes-it-easier-to-start-smoking-and-harder-to-quit/">loneliness</a> through the compassion, wisdom, and good judgment that comes along with life experience.

Previous studies have consistently found that social isolation and loneliness are risk factors for major health issues and unhealthy aging. In the last few decades, experts have become increasingly concerned about the impact of loneliness on middle-aged and older adults, in particular.

Study lead author Dr. Dilip V. Jeste is a professor of Psychiatry and Neurosciences and the senior associate dean for the Center of Healthy Aging at UC San Diego School of Medicine.

"An important finding from our study was a significant inverse correlation between loneliness and wisdom. People with higher scores on a measure of wisdom were less lonely and vice versa," said Dr. Jeste.

"Loneliness was consistently associated with poor general health, worse quality of sleep and less happiness, whereas the reverse was generally true for wisdom."

Using the UCLA Loneliness Scale and San Diego Wisdom Scale, the researchers examined four groups of adults aged 50 to 65 and those older than age 90 in both California and Italy. Among all four groups, the experts found a strong inverse correlation between loneliness and wisdom.

Dr. Salvatore Di Somma, the study's lead Italian investigator, is a professor of Emergency Medicine at the University of Rome La Sapienza.

"We translated the rating scales for loneliness and wisdom from English to Italian. It is remarkable that the findings related to these two traits were largely similar in two markedly different cultures - a rural region of southern Italy and an urban/suburban county in the United States, both with different native languages and unique historical, educational and socioeconomic backgrounds," said Dr. Di Somma.

The Cilento region is a relatively remote area of southwestern Italy that has a large population of individuals over the age of 90. The current research expands upon the Cilento Initiative on Aging Outcomes (CIAO) study, which was launched in 2016.

"Both loneliness and wisdom are personality traits. Most personality traits are partially inherited and partially determined by environment," said Dr. Jeste.

Wisdom has several important components, including empathy, compassion, self-reflection, and emotional regulation. The researchers found that empathy and compassion have the strongest inverse correlation with loneliness. Overall, people who are more compassionate tend to be less lonely, according to the study.

"If we can increase someone's compassion, wisdom is likely to go up and loneliness is likely to go down," said Dr. David Brenner. "At UC San Diego, we have considerable interest in enhancing empathy and compassion to reduce levels of stress and improve happiness and well-being."

According to Dr. Jeste, studies that help to determine how to combat loneliness as people age will be critical for effective interventions and the future of health care.

"Routine assessment of loneliness with evidence-based, compassion-focused interventions for prevention and management of loneliness should become an integral part of clinical practice," said Dr. Jeste. "So how do you increase compassion? Utilizing approaches like cognitive behavioral therapy or writing in a gratitude diary can help someone become more compassionate."

The study is published in the journal <a href="https://www.tandfonline.com/loi/camh20">Aging and Mental Health</a>.

It pays off to read labels and avoid products with harmful chemicals. A new study from the <a href="https://silentspring.org/">Silent Spring Institute</a> confirms that it pays off to read labels and seek out healthier products, such as shampoo that is free of parabens. The researchers found that consumers who try to avoid parabens and other endocrine disruptors have significantly lower levels of the <a href="http://www.earth.com/news/chemicals-from-plastics-leak-into-seabird-stomachs-over-time/">chemicals</a> in their bodies. 

Endocrine disruptors interfere with the body's hormones, which can lead to serious health issues such as reproductive disorders, thyroid disease, asthma, and certain types of cancer. Despite the potential harm they can cause, these chemicals are widely used in personal care and household products

"That's why expert scientific panels and medical societies recommend that people take steps to limit their exposure to these chemicals," said study lead author Dr. Robin Dodson. "And, with the current pandemic, we see how diseases associated with environmental chemicals also make people more vulnerable to COVID-19 - yet another reason to reduce exposures in the population."

To investigate the impacts of various types of products, Dr. Dodson and her team collected urine samples from 726 participants across the United States who signed up to join the Institute's biomonitoring project. The researchers analyzed the samples for 10 common endocrine disruptors.

The participants also completed an online survey, reporting on the products they use and whether they avoid products with certain chemicals listed on the label.

The analysis showed that 87 percent of participants were taking steps to avoid specific chemicals in products. These individuals were found to have lower levels of parabens, BPA, triclosan, and benzophone-3 compared with the general U.S. population. 

The experts determined that avoiding certain products and reading ingredient labels was the most effective way to reduce exposure to endocrine disruptors.

The study revealed that people who avoided products with parabens, triclosan, BPA, and fragrances were twice as likely to be in the group with the lowest body burden for all of the chemicals combined.

"This study not only helped us gain a better understanding of how product choices influence people's exposures to endocrine disruptors, but it also provided us with an opportunity to educate consumers and empower them to make healthier choices," said Dr. Dodson.

After the urine analysis, the participants received a personalized digital report that compared their chemical levels with the other participants as well as with national data. The report contained information on the health effects of the chemicals that were present in each individual's urine and how to avoid those chemicals.

By downloading Silent Spring's free mobile app Detox Me, the participants could learn more about reducing chemical exposures in their everyday environment.

However, Dr. Dodson emphasized that some chemicals are hard to avoid because it is unclear what products they are in. For example, some of the volunteers who said they avoided products with parabens still had high levels of parabens in their bodies. 

"What this study shows us is that people can't shop their way out of this problem," said Dr. Dodson. "This is about much more than consumer choice."

"Ultimately, encouraging companies to invest in safer alternatives and strengthening regulations to keep harmful chemicals out of products in the first place would be the most effective and equitable way to protect public health."

The study is published in the <a href="https://www.sciencedirect.com/journal/international-journal-of-hygiene-and-environmental-health">International Journal of Hygiene and Environmental Health</a>.

There may be more genetic mutations that contribute to human <a href="http://www.earth.com/image/many-fires-are-still-raging-across-california/">aging</a> than what was previously realized, according to a new study from <a href="https://liu.se/en">Linköping University</a>. The research supports a new theory about the type of mutation that drives the aging process. 

"The evolution of aging is, in a manner of speaking, a paradox. Evolution causes continuous adaptation in organisms, but even so it has not resulted in them ceasing to age," said study lead author Urban Friberg.

Almost 70 years ago, there were two theories proposed on the different types of mutations that contribute to aging. Both of these mutations are either beneficial or neutral early in life, yet become detrimental as the organism gets older, which leads to aging.

"In order for aging to evolve in response to a declining strength of selection with age, a genetic architecture that allows for mutations with age-specific effects on organismal performance is required," wrote the study authors. "Our understanding of how selective effects of individual mutations are distributed across ages is however poor."

"Established evolutionary theories assume that mutations causing aging have negative late-life effects, coupled to either positive or neutral effects early in life." 

The latest theory, however, suggests that the genetic mutations that cause aging are already harmful in early life and become increasingly damaging over time. 

To investigate, the experts focused their research used on the fruit fly, or Drosophila melanogaster. They tested 20 different mutations that they had introduced into the genetic material of the flies. 

For each separate mutation, the team studied a group of flies with the mutation and a control group without it. The mutations had specific, visible effects, which made it easy to follow, such as a somewhat different appearance of the wings or a different shape of the eyes.

The study revealed that the latest theory is correct: most of the mutations had a negative effect on the fertility of the fruit flies early in life, and most of them also caused reproductive aging to occur more rapidly.

"The results suggest that mutations that are detrimental early in life can also contribute to aging," said study co-author Martin Iinatti Brengdahl. "Thus it may be that mutations that bring on aging are significantly more common than we previously believed."The study is published in the journal <a href="https://bmcbiol.biomedcentral.com/submission-guidelines">BMC Biology</a>.

A national survey from <a href="https://www.rand.org/">RAND Corporation</a> reveals that Americans drastically increased their alcohol intake during the nationwide response to the coronavirus pandemic. A spike in alcohol consumption was particularly pronounced among women, who had a 41-percent higher frequency of heavy <a href="http://www.earth.com/news/lithium-in-public-drinking-water-may-lower-suicide-risk/">drinking</a> episodes with four or more drinks in a couple of hours.

The research is based on a survey of 1,540 adults who are members of the RAND American Life Panel, a nationally representative internet panel. The survey participants were asked about their alcohol consumption during the spring of 2019 and in spring 2020 during the early months of the pandemic shutdown.

Compared to the same time last year, the overall rate of alcohol consumption increased by 14 percent among adults over age 30. For individuals between the ages of 30 and 59, alcohol intake rose by an average of 19 percent.

Study lead author Michael Pollard is a sociologist at RAND, a nonprofit research organization.

"We've had anecdotal information about people buying and consuming more alcohol, but this is some of the first survey-based information that shows how much alcohol consumption has increased during the pandemic," said Pollard.

"Alcohol consumption can have significant negative health consequences, so this information suggests another way that the pandemic may be affecting the physical and mental health of Americans."

According to the researchers, the alcohol spike seen among women and younger adults highlights the need for primary care providers, behavioral health providers, and family members to be aware of the risks of increased alcohol use and heavy drinking during the pandemic.

The findings indicate that future research is needed to determine whether higher rates of alcohol consumption persist as the pandemic continues, and how mental and physical well-being are being affected.

The study is published in the journal <a href="https://jamanetwork.com/journals/jamanetworkopen">JAMA Network Open</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 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.”

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes why satellite images and measurements of our planet have become "essential to our survival, offering a new outlook of our world."&nbsp;



Rising sea levels pose one of the biggest societal threats associated with climate change. According to ESA, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.



"Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage," reports ESA.



"Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch."



Dr. Craig Donlon explains that, by understanding planet Earth through satellite measurements, we are able to find evidence of change.&nbsp;
