Creativity can flourish when you leave your comfort zone. A new study shows that relocating - or splitting time between different places - can help people start their most creative projects years earlier than those who stay put.



In fact, scientists from <a href="https://www.osu.edu/" target="_blank" rel="noreferrer noopener">The Ohio State University</a>, New York University in Abu Dhabi, and the U.S. Bureau of Economic Analysis found that Nobel Prize winners who moved more often started their prize-winning research significantly earlier than those who didn’t. 



The research, which analyzed Nobel laureates in chemistry, medicine, and physics from 1901 to 2003, was published in the journal International Economic Review.



<h2 class="wp-block-heading" id="h-creativity-needs-fresh-air">Creativity needs fresh air</h2>



The study found that Nobel laureates who relocated frequently began their groundbreaking work about two years earlier than those who never moved. 



Those who split their time between multiple institutions started even earlier - by as much as 2.6 years.



“They’re hearing interesting ideas at one place and different ideas at another location. They are putting these things together in novel, important ways,” said Bruce Weinberg, one of the study’s authors.



<h2 class="wp-block-heading" id="h-why-changing-scenery-matters">Why changing scenery matters</h2>



According to the researchers, switching locations helps scientists meet others with different perspectives. That mix of ideas can be powerful fuel for <a href="https://www.earth.com/news/experts-discover-a-pattern-that-drives-artistic-breakthroughs/" target="_blank" rel="noreferrer noopener">creative breakthroughs</a>.



“If they stayed in one place, it would take much longer to happen or may not happen at all,” Weinberg said.



Previous research has often focused on how clusters of scientists in one location - like Silicon Valley or Cambridge - drive innovation. But this new study highlights something different: the power of exposure to new ideas through movement.



“You can be in one place with lots of brilliant people, but after a while, you’ve talked to all of them and you develop a common understanding of how things work,” Weinberg said.



“You’re less likely to come up with this great breakthrough unless you are exposed to a new set of ideas you haven’t heard before. You can do that by moving or working in several locations.”



<h2 class="wp-block-heading" id="h-mobility-and-innovation">Mobility and innovation </h2>



The researchers built a detailed dataset tracking the yearly locations of Nobel Prize winners and the year they began the work that led to their awards. They discovered patterns that connect mobility with earlier innovation.



Moving every two years shaved off about two years from the time it took to begin Nobel-winning work. Relocating every five years led to a reduction of 0.7 years. 



Working in multiple places - like <a href="https://www.earth.com/news/nature-experiences-alter-time-perception/" target="_blank" rel="noreferrer noopener">balancing time</a> between a university and a large facility such as CERN - reduced the time to innovation by 2.6 years.



<h2 class="wp-block-heading" id="h-a-head-start-on-greatness">A head start on greatness</h2>



The data also revealed that about 5 to 10% of the Nobel laureates began their prize-winning work in the very first year of their careers. But others took 10, 20, or even up to 40 years.



“It’s not easy for a scientist to move their lab and work to a new location, but it can substantially boost their research,” Weinberg said.



Interestingly, the average time it took for laureates to start their Nobel work stayed consistent over the years, regardless of the scientific field.



<h2 class="wp-block-heading" id="h-what-this-means-for-the-rest-of-us">What this means for the rest of us</h2>



Academic sabbaticals might offer similar benefits by allowing scholars to work in new or multiple places, providing a potential boost to creativity. While the study didn’t measure sabbaticals directly, the authors noted that examining their effects on <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">creative output</a> would be a valuable next step.



“For someone who might have taken 10 years to begin their prize-winning research if they stayed in one place, moving every two years could reduce that time by nearly a quarter. That is substantially accelerating their innovations,” Weinberg said.



Though the study focused on a specific group of scientists, Weinberg believes the findings have broader implications for anyone whose work relies on creativity.



“Many scientists work the same way as our study's chemistry, medicine, and physics researchers. They can benefit by moving to new places and being exposed to new ideas,” he said.



“I think the same might even be true of great painters and <a href="https://www.earth.com/news/stone-age-artists-carved-incredibly-detailed-animal-tracks-onto-rocks/" target="_blank" rel="noreferrer noopener">artists</a> and anyone in a creative domain - their genius is coming up with novel ideas and expressing them in novel ways. And it helps to move and meet others with different ideas.”



<h2 class="wp-block-heading" id="h-creativity-thrives-outside-the-comfort-zone">Creativity thrives outside the comfort zone</h2>



Weinberg also mentioned that there might be an added boost to creativity simply from being in a new setting, even beyond the benefits of meeting new people.



“Going off into a completely different environment, a new context, might help <a href="https://www.earth.com/news/creative-people-make-the-most-of-their-idle-time/" target="_blank" rel="noreferrer noopener">creative people</a> think in new ways,” he said.



“You’re more likely to come up with that great new idea if you move around, meet new people, have new experiences, encounter new ways of thinking."



The full study was published in the journal <a href="https://onlinelibrary.wiley.com/doi/10.1111/iere.12768" target="_blank" rel="noreferrer noopener">International Economic Review</a>.

Need a creativity boost? Try a change of scenery

Creativity can flourish when you leave your comfort zone. A new study shows that relocating - or splitting time between different places - can help people start their most creative projects years earlier than those who stay put. In fact, scientists from The Ohio State University, New York University in Abu Dhabi, and the U.S. Bureau of Economic Analysis found that Nobel Prize winners who moved more often started their prize-winning research significantly earlier than those who didn’t.

China has confirmed that the scientist who oversaw the birth of the world’s first <a href="http://www.earth.com/news/gene-edited-dna-twin-babies/">gene-edited babies</a> acted illegally, according to a report from state-run Xinhua news.

One of the biggest ethical concerns surrounding <a href="https://www.earth.com/earthpedia-articles/gene-editing/">gene-editing and CRISPR-Cas9</a> technology is that these advancements could pave the way for “designer babies.”

Chinese authorities are now investigating He Jiankui, a Chinese scientist who shocked the world when he announced the successful births of two gene-edited twin girls, nicknamed Lulu and Nana, whose mother had undergone in-vitro fertilization and whose father had HIV. 

Jiankui explained that Lulu and Nana were perfectly healthy and that he had edited their genes so that they were resistant to HIV and would be unable to contract the disease. 

Gene surgery was performed when the twins were just a single cell to “close the door” to HIV, Jiankui explained in a video interview. 

While the idea that you could eradicate genetic diseases and risk of infection is a noble one, the risks of editing and snipping around the human genome cannot be taken lightly, and Jiankui’s unethical practices which had been shrouded in secrecy to avoid discovery broke every rule in the book.

While working at the <a href="http://www.sustc.edu.cn/en/">Southern University of Science and Technology (SUSTech)</a>, it’s believed that Jiankui privately funded the research project, hired a team of experts to carry out the work, and forged ethical review papers to recruit eight couples. 

In each couple, the father was HIV-positive and the mother negative. So far Lulu and Nana are the only twins born from the experiments, but another couple is pregnant, according to the team investigating Jiankui and his research. 

The university that Jiankui worked at has publicly condemned his actions and announced that the researcher was fired from his position at the school, according to the <a href="https://www.dailymail.co.uk/news/article-6614607/China-says-doctor-gene-edited-babies-acted-own.html">Daily Mail.</a> Another report argued that Jiankui had only conducted the research for <a href="http://www.xinhuanet.com/local/2019-01/21/c_1124020517.htm">personal gain and notoriety. </a>

Currently, Jiankui is under house arrest as the investigation into his work continues.

Most <a href="http://www.earth.com/news/environmentally-responsible-foods-class/">foods</a> that are accessible in the workplace are high in calories, refined grains, added sugars, and sodium. A new study from the <a href="https://www.cdc.gov/">Centers for Disease Control and Prevention</a> (CDC) has found that around 25 percent of adults employed in the United States obtain food at work at least once per week.

Based on data collected in 2012- 2013 from the Food Acquisition and Purchasing Survey (FoodAPS), CDC investigators determined that 23.4 percent of the 5,222 study participants ate food they acquired at work at least once a week. The average number of calories from workplace food was 1,292, and the products did not typically satisfy the Dietary Guidelines for Americans.

“Employers can offer appealing and healthy options in cafeterias, vending machines, and at meetings and social events,” said lead CDC investigator Dr. Stephen J. Onufrak. “One way to do this is by incorporating food service guidelines and healthy meeting policies into worksite wellness efforts.”

Improving the nutritional quality of foods available in the workplace could help to combat obesity and low dietary quality, which are important risk factors for chronic diseases such as heart disease, type 2 diabetes, and cancer. These conditions represent seven of the top 10 leading causes of death in the U.S., as well as 84 percent of healthcare costs. 

In 2010, nearly 30 percent of employed adults suffered from obesity. These adults also reported lower consumption of fruits and vegetables and less frequent physical activity compared to adults with healthier weight.

More than 150 million adults are employed in the United States, and worksite wellness efforts to prevent chronic disease can reach a large portion of them. These types of programs have been proven effective at changing health behaviors among employees, reducing work absence, and lowering healthcare costs.

“Incorporating food service guidelines into wellness programs can help employers offer appealing and healthy options that give employees a choice,” said Dr. Onufrak.

The study is published in the <a href="https://jandonline.org/">Journal of the Academy of Nutrition and Dietetics</a>.

A new study led by the <a href="https://ucsd.edu/">University of California San Diego</a> has found that general <a href="http://www.earth.com/news/fetal-exposure-air-pollution/">cognitive ability</a> (GCA) in early adulthood is a much better predictor of future cognitive function compared to other factors, such as higher education or late-life intellectual activities.

General cognitive ability is a diverse set of thinking skills that are used for reasoning, memory, and perception. Prior research has linked activities such as reading, socializing, solving puzzles, and completing a higher level of education to a reduced risk of dementia, but the current study suggests that a measure of GCA provides a more accurate indication. 


An international team of scientists set out to investigate based on an evaluation of more than 1,000 men participating in the Vietnam Era Twin Study of Aging. The participants, who are now in their 50s and 60s, had their GCA measured when they were an average age of 20 years old. 

For the current study, the researchers analyzed the individuals using the same GCA measure. The team also explored seven different cognitive domains, including memory and abstract reasoning.

The study revealed that GCA at age 20 accounted for 40 percent of the variance in the same measure at age 62, and approximately 10 percent of the variance for each of the seven cognitive domains. 

Compared to the GCA score at age 20, other factors had little effect. For example, lifetime education and engagement in intellectual activities each accounted for less than one percent of cognitive variance at the average age of 62.

“The findings suggest that the impact of education, occupational complexity and engagement in cognitive activities on later life cognitive function likely reflects reverse causation,” said study first author Professor William S. Kremen. “In other words, they are largely downstream effects of young adult intellectual capacity.”

Professor Kremen said remaining mentally active in later life is beneficial, but that the “findings suggest we should look at this from a lifespan perspective. Enhancing cognitive reserve and reducing later life cognitive decline may really need to begin with more access to quality childhood and adolescent education.”

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

A team of scientists at <a href="https://liu.se/en">Linköping University</a> has analyzed how the nervous system responds to being touched by another person compared to self-touch. The study sheds new light on how the <a href="http://www.earth.com/news/brains-cerebellum-addictive-behavior/">brain</a> makes the distinction, demonstrating that the processing of sensory perception is reduced when we are touching our own skin.

The ability to distinguish between self and others is extremely important, and problems with the concept of self are common in some psychiatric disorders. For example, patients with schizophrenia can tickle themselves, while most people who are not capable of making themselves feel ticklish. This suggests that the brain of a schizophrenic individual interprets sensory perceptions from their own body differently.

Sensory receptors in the skin transmit information about touch, pressure, heat, and cold to the spinal cord and on to the brain, where the perception is processed in different brain regions.

For the study, the team recorded images of brain activity while participants either slowly stroked their own arm or were stroked on the arm by one of the researchers. This enabled the experts to examine how these types of touch were linked to activity in different parts of the brain.

“We saw a very clear difference between being touched by someone else and self-touch. In the latter case, activity in several parts of the brain was reduced. We can see evidence that this difference arises as early as in the spinal cord, before the perceptions are processed in the brain,” said study lead author Rebecca Böhme.

The findings are consistent with a theory that the brain attempts to predict the sensory consequences of everything we do. In other words, the brain does not highly prioritize sensory perceptions that are caused by our own bodies because this type of sensory information is expected. 

“Our results suggest that there is a difference as early as in the spinal cord in the processing of sensory perceptions from self-touch and those from touch by another person. This is extremely interesting,” said Böhme. “In the case of the visual system, research has shown that processing of visual impressions occurs as early as in the retina, and it would be interesting to look in more detail into how the brain modulates the processing of tactile perceptions at the level of the spinal cord."

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Today’s always on, always on-the-go, and always plugged-in lifestyle can ramp up the body’s stress response into overdrive and make someone feel like they are constantly fighting an uphill battle. 

When the body’s <a href="http://www.earth.com/news/night-stress-response/">stress</a> response is turned on, your body releases a cocktail of hormones including adrenaline and cortisol which speed up your heart rate and cause many other physical side-effects related to stress. 

While these natural responses can be helpful in stressful situations, over time, they can negatively impact health and wellbeing. 

A recent study conducted by researchers from the <a href="https://www.uthscsa.edu/">University of Texas Health Science Center at San Antonio</a> found that stress, indicated by high levels of cortisol, can cause declines in cognition, impair memory, and shrink brain mass. 

The research was published in the journal <a href="http://n.neurology.org/content/91/21/e1961">Neurology</a>. 

“In our quest to understand cognitive aging, one of the factors attracting significant interest and concern is the increasing stress of modern life,” said Sudha Seshadri, the senior author of the study, in a <a href="https://news.uthscsa.edu/study-stress-can-impair-memory-reduce-brain-size-in-middle-age/">UT Health news release</a>. “In this study, higher morning cortisol levels in a large sample of people were associated with worse brain structure and cognition.”

The researchers analyzed data from 2,231 participants of the Framingham Heart Study. The average age for the participants was 48, and the researchers reviewed data on morning cortisol levels (measured after morning blood draws), cognitive functioning, and MRI scans that show brain volume. 

“Cortisol affects many different functions, so it is important to fully investigate how high levels of the hormone may affect the brain,” said Justin B. Echouffo-Tcheugui, a lead author of the study. “While other studies have examined cortisol and memory, we believe our large, community-based study is the first to explore, in middle-aged people, fasting blood cortisol levels and brain volume, as well as memory and thinking skills.”

The results showed that for middle-aged adults, high levels of cortisol correlated with cognitive declines, memory loss, and slight decreases in brain volume. 

The study emphasizes the importance of stress management as stress can have many adverse impacts later on in life. 

“The faster pace of life today probably means more stress, and when we are stressed, cortisol levels increase because that is our fight-or-flight response,” said Seshadri. “When we are afraid, when we are threatened in any way, our cortisol levels go up. This study adds to the prevailing wisdom that it’s never too early to be mindful of reducing stress.”

A new study has revealed that the growing popularity of Prosecco may come along with a high environmental cost. Researchers have found that the Veneto region of northeastern Italy is losing an enormous amount of soil across its steep hillside in the <a href="http://www.earth.com/news/winemakers-switch-grapes-climate/">vineyards</a> used for Prosecco production.  

The worldwide demand for Prosecco is growing at the fastest rate of any sparkling wine. For example, a 2016 assessment of global wine and spirits trends by <a href="https://www.theiwsr.com/">IWSR</a> predicted that Prosecco would grow by 36 percent through 2020, while Champagne would show only around one percent growth over the same time period. 

Currently, Northeast Italy is producing 400 million bottles of Prosecco per year, with 90 million bottles coming out of the historical Prosecco sector between the towns of Valdobbiadene and Conegliano. This area is defined as the Controlled and Guaranteed Designation of Origin (DOCG), where the highest quality wine standards are enforced.

A team of experts led by the <a href="https://www.unipd.it/en/">University of Padova</a> set out to investigate the soil erosion rate among vineyards in the DOCG area. The goal of the study was to calculate a type of “soil footprint” for Prosecco production, identify the hardest hit areas, and to develop mitigation strategies. 

The investigation revealed that 400,000 tons of soil is lost every year in the vineyards. While wine production is not the only source of soil erosion in the DOCG area, the research suggests that vineyards are responsible for nearly 75 percent of the total loss.

Based on an annual production of 90 million bottles of Prosecco, the experts calculated that each bottle was associated with a loss of 4.4 kilograms of soil.

Caroline Mazzey, a plant scientist at Hadlow College, was shocked by the results of the study. Mazzey told <a href="https://www.newscientist.com/">New Scientist</a>: “I find myself in disbelief. It’s more soil than the physical volume of the bottle.”

Vineyards have very little vegetation, which makes the soil highly susceptible to being washed away by rainfall. The researchers suggested that erosion could be substantially reduced by allowing grass to grow between rows of vines. 

However, an association representing DOCG Prosecco producers told New Scientist that this is already a common management practice. The consortium also disputed the findings of the study, with a representative stating: “These soil erosion estimates are, in our view, inaccurate. Managing erosion is a primary interest of the winegrower.”

The study, which has not yet been peer-reviewed, is published online at <a href="https://www.biorxiv.org/">bioRxiv.org</a>.

After researchers from Sweden’s <a href="https://www.uu.se/en">Uppsala University</a> studied fat distribution in 360,000 participants, they found that genetic factors greatly influence how our bodies store fat. The team, whose findings are published January 21st in <a href="https://www.nature.com/ncomms/">Nature Communications</a>, also found that this genetic influence is more predominant in women than in men.

"We know that women and men tend to store fat differently - women have the ability to more easily store fat on the hips and legs, while men tend to accumulate fat around the abdomen to a higher extent," said lead author and postdoctoral researcher at Uppsala’s department of Immunology, Genetics and Pathology, Mathias Rask-Andersen, Ph.D. "This has been attributed to the effects of sex hormones such as estrogen. But the molecular mechanisms that control this phenomenon are fairly unknown."

Using participant blood samples, the researchers were able to genotype and measure <a href="http://www.earth.com/news/physical-activity-reduces-belly-fat/">fat distribution</a> using impedance measurements, those being measurements of electrical resistance to an electrical current that is fed through the body. They then tested millions of genetic variants for connections to fat distribution in the arms, legs, and bottom. The team found hundreds of genes that affect bodily fat distribution and a high degree of heterogeneity between males and females.

"We were struck by the large number of genetic effects that were stronger, or only present, in females. Upon closer examination, several of the associated genes were found to encode proteins that actively shape the extracellular matrix, which makes up the supporting structure around cells," said Åsa Johansson, the group leader docent.

The study’s findings may help future researchers develop new methods of reducing the risk of cardiovascular disease. Males with abdominal fat are usually at a greater risk of cardiovascular disease, whereas women who store fat in their legs and hip and leg region are at lesser risk.

"The biological systems we highlight in our study have the potential to be used as points-of-intervention for new drugs that are aimed at improving the distribution of body fat and thereby reducing the risk of disease," Mathias Rask-Andersen concluded.

<a href="http://www.mit.edu/">MIT</a> researchers have discovered a link between high levels of <a href="http://www.earth.com/news/annual-air-pollution-crisis-asia/">air pollution</a> and low levels of happiness among urban populations in China. This may explain why satisfaction levels have not risen as much as expected during the country’s significant economic growth.

Previous research from <a href="http://www.cuhk.edu.hk/">Chinese Hong Kong University</a> found that air pollution is responsible for 1.1 million premature deaths each year in China. Furthermore, experts have demonstrated that air pollution is damaging to health, cognitive performance, labor productivity, and educational outcomes.

According to lead author Professor Siqi Zheng, the findings of the current study show that air pollution also has a broader impact on people's social lives and behavior. For example, people may move to a new region, buy protective masks and equipment, or spend less time outdoors to avoid high levels of air pollution.

“Pollution also has an emotional cost,” said Professor Zheng. “People are unhappy, and that means they may make irrational decisions.”


On days with higher levels of pollution, people are known to be more likely to engage in impulsive and risky behavior. Professor Zheng said this could be the result of short-term depression and anxiety. “So we wanted to explore a broader range of effects of air pollution on people's daily lives in highly polluted Chinese cities,” she explained. 


The team compared data from social media and information on urban levels of fine particulate matter to track how daily pollution levels may have impacted the happiness of residents in 144 Chinese cities. The researchers applied a machine-learning algorithm to analyze the 210 million tweets from China's largest microblogging platform, Sina Weibo.

The experts found evidence of a significant correlation between pollution and happiness levels. They also determined that women were more sensitive to higher pollution levels than men.

When the researchers examined where the tweets originated from, they found that residents of the very cleanest and very dirtiest cities were the most affected by pollution levels. According to Professor Zheng, this may be because those people who are particularly concerned about their health and air quality tend to move to clean cities, while those in very dirty cities are more aware of the damage to their health from long-term exposure to air pollution.

The study is published in the journal <a href="https://www.nature.com/nathumbehav/">Nature Human Behaviour</a>.

Researchers at the <a href="https://www.uvm.edu/">University of Vermont</a> are reporting that individual choice is not really an option when it comes to social media. The study revealed that sites such as Facebook and <a href="http://www.earth.com/news/twitter-bots-2016-election/">Twitter</a> can even compromise the privacy of those who choose not to engage on these platforms. 

The analysis presents powerful evidence that, when it comes to social media, an individual’s behavior is no longer their own private business. 

The investigation was focused on more than thirty million public Twitter posts by 13,905 users. Information within the Twitter messages from 8 or 9 of a person's contacts made it possible for the experts to accurately predict the individual’s future tweets without even looking at their news feed.

The study also revealed that after a person closes a social media account, or never joins in the first place, the online posts and words of their friends still provide about 95 percent of the “potential predictive accuracy” of a person's future activities. In other words, using absolutely none of your own personal data, others may be able decipher your daily plans. 


Study lead author James Bagrow said that when you sign up for Facebook or another social media platform, “you think you're giving up your information, but you're giving up your friends' information too!”

The study findings suggest that any type of user, including a company or the government, can accurately profile a person from their friends, even if they have never been on social media before. “There's no place to hide in a social network,” said study co-author Lewis Mitchell.

Professor Jim Bagrow added, “You alone don't control your privacy on social media platforms. Your friends have a say too.”

The study is published in the journal <a href="https://www.nature.com/nathumbehav/">Nature Human Behavior</a>.

Beating cancer often comes with significant financial burden. A new study published by the <a href="https://www.cancer.org/">American Cancer Society</a> has revealed that cancer survivors face a bigger financial burden when it comes to medical bills compared to individuals who have no history of <a href="http://www.earth.com/news/us-cancer-mortality-rates-declining/">cancer</a>, and the greatest hardships were found among younger survivors. 

The researchers also found that privately insured survivors who enrolled in high deductible health plans were particularly susceptible to mounting medical debts. Beating cancer often comes with significant financial burden

Medical financial hardship can be divided into three main categories: material hardships, such as problems paying medical bills; psychological worry over paying medical bills; and behavioral hardships, such as not seeking help to avoid financial strain.


A team of researchers led by Dr. Zhiyuan Zheng set out to investigate the basic aspects of medical financial hardship in adults with and without a cancer history. The study was focused on data from the 2013 to 2016 National Health Interview Survey, which represented 10,354 cancer survivors as well as 124,436 respondents with no history of cancer.

Compared with those without a cancer history, cancer survivors were significantly more likely to report any material hardship, psychological hardship, and behavioral hardship.

“Identifying patients with medical financial hardship will be important for primary care and oncology care providers,” said Dr. Zheng. “Developing and evaluating interventions to minimize medical financial hardship will be important for the research community. It may also require attention from health policy makers.”

Dr. Zheng noted that younger cancer survivors between the ages of 18 and 49 experienced greater financial hardship. 

“It may be that they do not have the opportunity to accumulate financial assets to pay for medical expenses. In addition, a cancer diagnosis might interrupt employment, and consequently limit access to employer-sponsored health insurance coverage.”

“Although we could not identify the underlying reasons for greater hardship intensity in the younger group in this study, we believe it will be an important area for additional research.”

Helping plants and pollinators may be as simple as turning off street lights for a couple of hours a night.

That was the conclusion of a team of researchers from <a href="https://www.ncl.ac.uk/">Newcastle University</a> and <a href="https://www.yorku.ca/">York University</a> who wanted to determine how light affects nocturnal pollinators like moths.

"Artificial light at night is an increasingly important driver of global environmental change and sky brightness is increasing by about 6 percent a year," study co-author Dr. Darren Evans said. "Understanding the ecological impact of this artificial light on the ecosystem is vital.”

The study found that bright street lights at night draw moths upward to flit around the light source rather than pollinate as usual. That has a large effect on the plants that rely on moths for pollination, including pea, soy and rapeseed crops. 

But turning off the street lights – even if only for a couple of hours – sent moths back to the plants they prefer to feed on. 

The researchers found that while constant overnight light badly disrupted pollination, even just a partial “lights out” period had a similar effect on moths’ feeding patterns as full darkness.

"We know that light pollution significantly alters moth activity and this in turn is disrupting their role as pollinators. But what our study showed was that while full-night lighting caused significant ecological disruption, part-night lighting did not appear to have any strong effect on pollination success or quality,” Evans said.

Whether street lights use sodium or LED bulbs had no apparent effect. It wasn’t the type of light, but the amount, that seemed to throw off moth feeding patterns. 

It’s the latest in a number of studies about the effects of light pollution on humans and the world around us. Studies have shown that light pollution can <a href="https://www.earth.com/news/light-pollution-sleep-problems/">disrupt sleep</a>, leading to chronic insomnia and dependence on sleep aids.

Light pollution from street lights doesn’t just affect humans and moths. It can <a href="https://www.earth.com/news/light-pollution-migrating-bats/">endanger migrating bats</a>, harm the various bugs that live in <a href="https://www.earth.com/news/light-pollution-streams-wetlands/">wetlands</a> and disrupt the food chain, disorient sea turtles and fool plants into thinking <a href="https://www.earth.com/news/artificial-light-pollution-causes-spring-to-come-early/">spring has come early</a>.

"Often, as conservationists, we have to make difficult trade-offs between development and environmental protection,” lead author Dr. Callum Macgregor said. "However, our study suggests that turning off street lights in the middle of the night is a win-win scenario, saving energy and money for local authorities whilst simultaneously helping our nocturnal wildlife."

If you often feel isolated, the cause may go deeper than you think. Genetic researchers have found that loneliness genes may be behind those solitary feelings, at least some of the time.

But that doesn’t mean you’re doomed to sadness. Putting yourself into fulfilling social situations can head off feelings of isolation before they set in.

To see whether loneliness genes exist and how nature and nurture affect feelings of friendlessness, researchers from the <a href="https://www.uwo.ca/">University of Western Ontario</a> looked at the lives of adult twins.

They found that the twins had very similar experiences up until they reached school age – and often, ended up in different classrooms. In pairs of twins more prone to loneliness, whether or not they made friends and developed a social life had an impact on how lonely they felt.

“If one makes friends in their class and is happy with the level of interaction they are having with other people, they are less likely to feel lonely,” lead author Dr. Julie Aitken Schermer told the <a href="https://www.dailymail.co.uk/home/index.html">Daily Mail</a>. “The [identical] co-twin has the same genetic likelihood of loneliness and is in an environment that is not as fulfilling in terms of relationships, they are more likely to experience feelings of loneliness.”

That may seem obvious.

But loneliness genes played a role, too. Identical twins were more likely to feel similar levels of loneliness regardless of their environment than fraternal twins. And those with a tendency toward neuroticism – one of the “big five” personality traits that DNA can influence – were more prone to feeling isolated.

“If you're neurotic you're more likely to worry about your situation, your lot in life, and ruminate and that may exasperate your feelings of loneliness,” Aitken Schermer said.

Researchers found a couple of ways to help relieve neuroticism and loneliness: practicing mindfulness, and cutting down screen time. 

While some people may need more face time to counteract their loneliness genes than others, even introverts should make an effort to connect, Aitken Schermer said.

“We have to realize that we are social beings and having feelings of isolation is not a character fault and go interact with people,” she said. “It's not a weakness on your part, you're showing insight into yourself. If you're hungry, go eat.”

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



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



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



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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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



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



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

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



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



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

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



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

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



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



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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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