Beauty has long captured our attention. From ancient times to modern life, people have turned to art for more than decoration.



Now, there’s scientific evidence that stopping to appreciate beauty - really stopping to take it in - can help us think beyond the moment.



A new study from the <a href="https://www.cam.ac.uk/" target="_blank" rel="noreferrer noopener">University of Cambridge</a> shows that reflecting on beautiful works of art can push our minds into a different gear. 



Instead of getting caught in the routine of daily life, we may begin to think more abstractly. That means we start considering the bigger picture - beyond the to-do lists and small details.



<h2 class="wp-block-heading" id="h-power-of-beauty-in-art">Power of beauty in art </h2>



Psychologists from the University of Cambridge set up an experiment in Kettle’s Yard, the university’s modern <a href="https://www.earth.com/news/simply-looking-at-art-can-improve-your-well-being/" target="_blank" rel="noreferrer noopener">art</a> gallery. They used the gallery as a kind of living lab to test how people respond to artistic beauty.



Participants viewed handmade ceramic pieces by artist Lucie Rie. One group was asked to focus on the beauty of each object and rate it. Another group simply matched each object with a line drawing. 



Everyone was then tested on how they interpret everyday concepts like writing a letter or locking a door. Were they focused on the physical action, or on its deeper meaning?



The results were clear. Those who focused on beauty were more likely to think in abstract ways. Participants also reported stronger emotional reactions - they felt moved, inspired, or enlightened.



<h2 class="wp-block-heading" id="h-a-shift-in-mindset">A shift in mindset</h2>



Simone Schnall is a professor of experimental social psychology at Cambridge and senior author of the study. She noted that many philosophers throughout history have suggested that engaging with aesthetic beauty invokes a special kind of psychological state.



“Our research indicates that engaging with the beauty of art can enhance abstract thinking and promote a different mindset to our everyday patterns of thought - shifting us into a more expansive <a href="https://www.earth.com/news/the-emotion-vocabulary-we-use-reflects-our-true-state-of-mind/" target="_blank" rel="noreferrer noopener">state of mind</a>," said Schnall.



“This is known as psychological distancing, when one snaps out of the mental trappings of daily life and focuses more on the overall picture.”



<h2 class="wp-block-heading" id="h-why-simpler-art-speaks-louder">Why simpler art speaks louder</h2>



The choice of art mattered too. The team deliberately avoided bold or dramatic artworks. 



“Ceramics were ideal for our purposes,” said Schnall. “A glorious <a href="https://www.earth.com/news/van-goghs-the-starry-night-masterpiece-captured-real-world-physics/" target="_blank" rel="noreferrer noopener">painting</a> by an Old Master would be too striking. We needed art that is subtle in form, requiring a focused contemplation of the nature of beauty.”



Even among participants who already had artistic <a href="https://www.earth.com/news/hobbies-keep-the-brain-sharp-and-slow-cognitive-aging/" target="_blank" rel="noreferrer noopener">hobbies</a>, the effect of engaging with beauty was stronger. 



People with artistic interests in the beauty group scored more than 25% higher in abstract thinking than their counterparts who only completed the line-drawing task.



Researchers also measured the emotional responses. On average, those in the beauty group felt 23% more “transformed” than those in the control group. But interestingly, they didn’t report being any happier. This suggests that the power of beauty lies in shifting thought patterns, not just lifting moods.



“Visiting an art museum is not just a pleasant way to spend an afternoon, it may actually change how we think about our lives,” said Schnall.



<h2 class="wp-block-heading" id="h-escaping-screens-through-art">Escaping screens through art</h2>



It’s easy to go through the day focused only on what needs doing next. Screens keep us locked into routines. We check off tasks. We swipe, scroll, and reply. What’s harder is making time to think freely, or to step back from the flow of things.



“People today are often tethered to their devices, and we usually think in very concrete terms when we’re doing something on a screen,” added Schnall.



“It’s becoming much rarer to zone out and just let the mind wander, but that’s when we think in ways that broaden our horizons. Admiring the beauty of art may be the ideal way to trigger the abstract cognitive processes increasingly lost in a world of screens and <a href="https://www.earth.com/news/toxic-blue-light-from-smartphones-may-accelerate-aging/" target="_blank" rel="noreferrer noopener">smartphones</a>.”



<h2 class="wp-block-heading" id="h-beauty-isn-t-just-felt-it-s-understood">Beauty isn’t just felt - it’s understood</h2>



The Cambridge team’s study adds to a growing body of research on how our environments shape our thinking. It also raises the idea that museums and galleries can play an important role beyond entertainment or education. They may actually help us live more thoughtful, reflective lives.



“Our findings offer empirical support for a long-standing philosophical idea that beauty appreciation can help people detach from their immediate practical concerns and adopt a broader, more abstract perspective,” said Dr. Elzė Sigutė Mikalonytė, lead author of the study and a researcher at Cambridge’s Department of Psychology.



This research is part of a larger project supported by the Templeton Religion Trust, exploring whether art can contribute to human flourishing and meaningful living. Based on what the researchers have found so far, the answer might be yes - if we take the time to really look.

Beauty in art lifts the mind and awakens higher thought

Beauty has long captured our attention. From ancient times to modern life, people have turned to art for more than decoration. Now, there’s scientific evidence that stopping to appreciate beauty - really stopping to take it in - can help us think beyond the moment. A new study from the University of Cambridge shows that reflecting on beautiful works of art can push our minds into a different gear.

A report released earlier this week reveals that <a href="https://www.earth.com/news/cities-combat-climate-change/">climate change</a> is not a future problem that we may be able to prevent, but already a critical public health issue. The impacts of air pollution and heat waves are causing serious health consequences for millions of people and weakening labor productivity across the globe.

“The Lancet Countdown: Tracking Progress on Health and Climate Change” is the result of an international, multidisciplinary collaboration from the British medical journal <a href="http://www.thelancet.com/journals/lancet/issue/current">The Lancet</a>. The research closely examines five various aspects of what the authors refer to as the “complex association between health and climate change.” 

"The human symptoms of climate change are unequivocal and potentially irreversible - affecting the health of all populations today," says the report. In addition, the consequences are disproportionately affecting communities that are least responsible for climate change yet most vulnerable to its impacts, according to the researchers.

While most research on climate change focuses on future impacts, this research demonstrates that critical health impacts of environmental changes are now occurring across the globe. "The delayed response to climate change over the past 25 years has jeopardized human life and livelihoods," say the authors of the study.

The analysis found that between 2000 and 2016, there was a 46 percent spike in the number of weather-related disasters. Within the same time frame, 125 million more people were exposed to heat waves than in previous decades. Furthermore, harmful exposure to air pollution increased by 11.2 percent worldwide since 1990.

The research also determined that global warming is accelerating the spread of Dengue fever and lengthening the duration of allergy seasons in the United States.

Despite these and other discouraging findings from the investigation, the researchers point out that “the past five years have seen an accelerated response, with momentum building across many sectors.” Greenhouse gas emissions are being cut back and a transition from coal to renewable energy has started. “Unprecedented gains in public health" will follow as climate change is tackled, say the authors.

“Preventing illnesses and injuries is more humane, more effective and more economical than treating people once they’ve become sick,” explains study co-author Howard Frumkin of the <a href="http://sph.washington.edu/">University of Washington School of Public Health</a>. “What this report makes clear is that fighting climate change is disease prevention.”

The Lancet Countdown follows up on the work of the 2015 Lancet Commission, which arrived at the conclusion that global response to climate change could be “the greatest global health opportunity of the 21st century.” The Lancet Countdown will continue to track progress on health and climate change every year.

A new study has found that depression is on the rise in the United States, especially amongst teens. Unfortunately, treatment for depression has not mirrored this rise, leaving many cases untreated and undiagnosed. 

The study was conducted by researchers from the <a href="https://www.mailman.columbia.edu/">Columbia University Mailman School of Public Health</a> and was published in the journal. Psychological Medicine. 

The findings pose a serious problem for public health, as the most rapid rise in depression was among younger Americans, ages twelve to seventeen. 

“Depression appears to be increasing among Americans overall, and especially among youth,” said Renee Goodwin, leader of the research from the Department of Epidemiology at Mailman School of Public Health.

Goodwin also noted that undiagnosed depression is one of the highest risk factors for suicidal behaviors. 

The study used data from the National Survey on Drug Use and Health, which is an annual study involving participants ages 12 and up. 

The researchers analyzed data from a little over 600,000 respondents to the Drug Use and Health survey, using criteria from the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders to measure the prevalence of depression among the survey responders. 

It is the first study of its kind to examine depression and analyze trends based on gender, income, and education. 

The results show that depression is increasing in the United States, with a jump from 8.7 percent in 2005 to 12.7 percent in 2015 in those ages twelve to seventeen.

The researchers found that depression rates increased most among young and old age groups, whites, lower and higher income groups, and among those with higher education levels. 

The findings are significant as they reveal the lack of treatment options for people with depression who don’t have good access to health care, even though depression is one of the most treatable mental disorders. 

The researchers found risk groups in different backgrounds, income levels, and ages which can hopefully inform outreach efforts and improve access and treatment options for individuals with <a href="https://www.earth.com/news/depression-risk-early-death/">depression</a>.

Participants in a recent study who ate spicy foods were found to be less likely to eat too much salt and more likely to have lower blood pressure. Both of these benefits combined make individuals less susceptible to a <a href="https://www.earth.com/news/cold-weather-heart-attack/">heart attack</a> or stroke.

Zhiming Zhu, M.D., the study's senior author, is the director of the Department of Hypertension and Endocrinology at the <a href="http://www.tmmu.edu.cn/">Third Military Medical University</a>. 

"Previously, a pilot study found that trace amounts of capsaicin, the chemical that gives chili peppers their pungent smell, enhanced the perception of food being salty," said Dr.Zhu. "We wanted to test whether this effect would also reduce salt consumption."

The research team focused their evaluation on 606 Chinese adults. They determined the participants’ preferences for salty and spicy flavors, and then linked those preferences to blood pressure. 

The study revealed that the individuals who most preferred spicy foods had lower systolic and lower diastolic blood pressure numbers. These adults were also found to consume significantly less salt compared to subjects who had a low spicy food preference.

Using imaging techniques, the researchers also examined two areas of the participants' brains known to be activated by salty taste. They discovered that the areas excited by salt and spice overlapped, and that spice further increased activity in brain regions stimulated by salt. The authors of the study explained that this heightened stimulation makes people more sensitive to salt so that they can enjoy food with less of it.

"If you add some spices to your cooking, you can cook food that tastes good without using as much salt," said Dr. Zhu. "Yes, habit and preference matter when it comes to spicy food, but even a small, gradual increase in spices in your food may have a health benefit."

While salt and sodium are often mistaken to be the same thing, they actually quite different. Over 75 percent of the sodium consumed by Americans comes from processed and restaurant foods, and not out of a salt shaker. The research is published in in the American Heart Association's journal <a href="https://www.medicalnewstoday.com/articles/150109.php">Hypertension</a>.

A new study shows that political views have a limited impact on our perception of <a href="https://www.earth.com/news/cities-combat-climate-change/">climate change</a>. The researchers found this to be particularly true when people observe weather conditions which persistently deviate from what is expected.

Human activities are altering the function of the very ecosystems that we all depend upon for survival. To preserve ecological services such as food and water which are critical to the sustainment of human life, humans must become aware of indications that these ecosystems are deteriorating.

At times, signals of ecosystem decline are obvious and can be easily detected. During a water pollution event, for example, it is noticeable that major changes are taking place. At other times, however, the signals are much more subtle and subject to distortion by political motivation or biases.

Researchers at the <a href="https://www.ou.edu/">University of Oklahoma</a> and <a href="https://go.okstate.edu/">Oklahoma State University</a> set out to develop a study on how people perceive climate anomalies such as extreme temperatures or rainfall. The study was focused on people in Oklahoma, a conservative state where a large portion of the population is skeptical about human-caused climate change.

The research team compared high-resolution climate data to the Meso-Scale Integrated Socio-geographic Network (M-SISNet), a panel survey that keeps a consistent measure of the public's perceptions of climate conditions.

"We found that, apart from slight biases at the extreme ends of the political spectrum, people in Oklahoma - a state where the concept of 'global warming' traditionally gets quite a chilly reception - readily perceived feedback from the climate system,” explained lead author Dr. Joseph Ripberger.

"We saw individuals drawing on objective signals, such as departures from average rainfall and temperatures, when they revised their perceptions of climate feedback. As you would expect, this revision was at its most pronounced when the signals were large and consistent,” said Dr. Ripberger.

The results of the study will be encouraging for anyone hoping to see climate change policies agreed upon across party lines.

"While more work is needed to understand how this kind of updating affects broader beliefs about climate change and public policy, analysis of dynamic data on human perceptions allows us identify similarities across the partisan spectrum,” said co-author Dr. Hank Jenkins-Smith.

"These similarities bode well for efforts to promote mitigation, adaptation, and resilience, as human systems continue to interact with a changing climate," said Dr. Smith.

The study is published in the journal <a href="http://iopscience.iop.org/erl">Environmental Research Letters</a>.

With regions across the country experiencing summer-like temperatures well into October, it may come as no surprise that the winter season in the United States is getting shorter. Weather statistics from over 100 years show that the freeze season is now arriving over a month later than it did in the 20th century.

This month, just 40 percent of the country saw their first freeze by October 23rd versus the expected 65 percent, according to Jeff Masters of <a href="https://www.wunderground.com/">Weather Underground</a>. Further evidence of a <a href="https://www.earth.com/news/climate-change-europe-drought/">changing climate</a>, the delayed freezing temperatures have both good and bad consequences. The fruit and vegetable growing season lasts longer, yet so do warm weather pests and outdoor allergy triggers.

Ken Kunkel, a meteorologist at the <a href="https://www.ncei.noaa.gov/">National Centers for Environmental Information</a>, examined data from 700 weather stations across the United States going back to 1895. Kunkel determined that the delayed freezing trend started around 1980. He also found the freeze season in 2016 started two weeks later than the 20th century average, and the last spring frost occurred generally nine days earlier. 

Overall, the winter freeze of 2016 was more than a month shorter than that of 1916. The Pacific Northwest was affected the most, with the frost season in Oregon declining by 61 days. Kunkel told the <a href="https://www.ap.org/en-us/">Associated Press</a> that the 2016 season was “way off the charts.”

Kunkel and other scientists agree that the freeze trend is an expected result of global warming, but also has some ties human activities. Kevin Trenberth, a climate scientist at the <a href="https://ncar.ucar.edu/">National Center for Atmospheric Research</a>, said the exceptionally later freeze “represents the kind of conditions that will be more routine in a decade or two” due to manmade climate change.

According to Jason Furtado, a professor of Meteorology at the <a href="https://www.ou.edu/">University of Oklahoma</a>, this shrinking freeze season is what climate scientists have long predicted.

As the global population grows and carbon dioxide emissions increase, future generations will become even more susceptible to the devastating impacts of <a href="https://www.earth.com/news/climate-change-costing-billions/">climate change</a>. According to a new study, the value that society chooses to place on the human population will directly affect how much money is invested in policies, such as carbon taxes, to protect future generations.

The cost of reducing greenhouse gas emissions will become billions or more over the next few decades, causing major challenges for policymakers. A research team set out to identify the ideal measures of climate mitigation, and used a climate-economic model to evaluate two different approaches to valuing the human population.

One approach assessed by the researchers assumes that society hopes to improve upon the number of people who experience well-being and happiness. The other approach assumes that society prefers to increase the average overall happiness and well-being of a population. 

The researchers found that with both ethical approaches, a smaller population could save billions of dollars on climate change prevention policies. These findings offer insights into the influence of population growth and population ethics on climate change and human development policy. 

The experts also determined that investment in human development programs could result in avoided climate change mitigation costs enough to pay for the programs themselves. Noah Scovronick is the study’s co-lead author and a postdoctoral research associate at Princeton University's Program in Science, Technology, and Environmental Policy (STEP), which is based at the <a href="http://wws.princeton.edu/">Woodrow Wilson School of Public and International Affairs</a>.

"With higher population growth, more people will be vulnerable to climate change. Understanding how much society values those future people should be an influential component of climate policy decisions," said Scovronick. 

Under both ethical approaches, wealthier regions would save the most per capita. But if society desires to increase average happiness instead of wanting to increase the number of people who are happy, the result is mitigation cost savings of tens of billions of dollars a year. 

"We have a responsibility to protect future people against unacceptable levels of harm from climate change, but how should we value them in our policy analyses?" said co-lead author Mark Budolfson from the <a href="http://www.uvm.edu/">University of Vermont</a>. "That's the essential question of this research, and we hope future research will investigate this further."

The study published in the <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a> (PNAS).

Well this explains a lot. A new study has found that junk food is actually twice as distracting as healthy food. 

The study was conducted by researchers from <a href="https://www.jhu.edu/">John Hopkins University</a> who discovered that people who are hard at work are easily distracted by pictures of junk food, but after a few bites of candy, junk food lost its initial appeal. 

The research was published in the journal Psychonomic Bulletin and Review and confirms the old saying that you should never shop hungry. 

“What your grandmother might have told you about not going to the grocery store hungry seems to be true. You would probably make choices that you shouldn't or ordinarily wouldn't,” said Corbin A. Cunningham, the lead author. 

For the study, the researchers created a computer task for a group of participants to perform. In the task, <a href="https://www.earth.com/news/food-allergies-develop-adult/">food</a> was irrelevant, and the study participants had to answer questions as quickly as they could. 

“We wanted to see if pictures of food, particularly high-fat, high-calorie food, would be a distraction for people engaged in a complicated task,” said Howard Egeth, a co-author of the study. “So we showed them carrots and apples, and it slowed them down. We showed them bicycles and thumbtacks, and it slowed them down. But when we showed them chocolate cake and hot dogs, these things slowed them down about twice as much.” 

As the subjects performed the computer tasks, random pictures would flash briefly in the periphery of the screen, a mix of images of fatty snacks, healthy foods, and non-food items like bicycles. 

All the pictures were distracting, but the junk food pictures like potato chips and candy were twice as distracting as the other healthy food and non-food pictures. 

For the second experiment, the researchers gave a new group of participants the same computer task to complete, but before the subjects went to answer the questions, they were given two fun-sized candy bars to eat. 

In this group, the participants were less distracted by junk food, having the same reaction to all the images equally, likely because their cravings for fatty foods were met when they were given the candy bars to eat before the task. 

The results beg the question if other snacks or less chocolate would yield similar outcomes.

“But what if we gave them an apple? What if we gave them a zero-calorie soda? What if we told the subjects they'd get money if they performed the task quickly, which would be a real incentive not to get distracted. Could junk food pictures override even that?” asked Egeth.

Nanotechnology could revolutionize fashion – by making climate control clothing that can automatically warm up or cool down for the wearer’s comfort. 

Scientists have developed tiny “nanocapsules,” made of a starchy outer shell and filled with a waxy substance, that can be woven into the fabric. The nanocapsules are invisible to the naked eye, but can provide powerful temperature control.

That’s because, as the wearer’s body heats up, the wax inside each capsule melts and absorbs the heat. Then, as the body cools down, the wax solidifies, releasing the stored heat.

“It can be used for outdoor clothing, sportswear and everyday clothing,” Dr. Carla Silva, who created the fabric, told the <a href="http://www.dailymail.co.uk/">Daily Mail</a>. “It could especially improve the comfort of those less able to control their body temperatures, such as young children and the elderly.”

Those with chronic illnesses or spinal cord injuries that affect the autonomic nervous system may also have problems with body temperature regulation. Clothing using the team’s nanocapsules could help.

The wax inside the nanocapsules melts and re-solidifies, but it cannot escape the starchy exterior. It works by mimicking the sweating process. As sweat evaporates, it helps to disperse heat. 

Silva, a lead researcher at the <a href="http://www.scienceportugal.com/en/institutions/centi-centre-for-nanotechnology-and-smart-materials/">Centre for Nanotechnology and Smart Materials</a> in Portugal, helped to develop a similar <a href="https://phys.org/news/2017-07-intertwined-nanotech-eczema.html">nanocapsule fabric that will treat eczema</a> earlier this year. She and her team hope to adapt the technology to also be able to treat bacterial infections and other skin disorders.

The nanocapsules can be chemically bonded to fabric, and are resistant to washing. 

Silva and her team are working with <a href="http://www.devan.net/">Devan Chemicals</a>, a Belgian company, to develop the nanocapsule technology for both the climate control clothing and the skin treatment.

Additional funding for the team’s research was provided by the <a href="https://europa.eu/european-union/index_en">European Union</a>.

Combating climate change will take a mass effort on both global and local scales. But now that the Trump administration has pledged to dismantle the Obama-era <a href="https://www.earth.com/news/pruitt-clean-power-plan/">Clean Power Plan</a>, new strategies will be needed to forge ahead. 

A recent study from the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a> (MIT) offers some new ideas of how cities can combat the effects of climate change on a local level. Co-authored by professor David Hsu, the study suggests that cities should focus on cutting emissions from residential use as opposed to transportation.

The research found that cities could significantly reduce greenhouse gas emissions by changing planning policies and residential building codes with smarter building practices, as opposed to increased housing density.

According to the <a href="https://www.eia.gov/">U.S Energy Information Administration</a>, housing accounts for 20 percent of carbon dioxide emissions in the United States.

“Our take-home message is that cities can do a lot at the local level with housing stock. In transportation, cities can't make up for the loss of a national strategy,” said Pro Hsu.

Some cities that don’t see as much residential development, such as Houston or Phoenix, won’t gain as much from new policies. But changes in planning and building still have potential to mitigate climate change across the board. 

“You can do a lot of things at the local level to affect housing stock that are basically equivalent or even more aggressive than the Clean Power Plan,” said Hsu. 

For the study, the researchers collected economic, environmental and demographic data from eleven major cities in the United States: Atlanta, Boston, Chicago, Cleveland, Denver, Houston, Los Angeles, Miami, Philadelphia, Phoenix, and Seattle.

The data was then used to help develop models that would project greenhouse gas emissions through the year 2030 based on different scenarios involving changes in housing and development and later, transportation.

Some of the scenarios that cut emissions included putting in place new energy-efficient construction standards, building multi-family homes, and retrofitting old homes to be more efficient.

The results showed that retrofitting existing homes to be energy efficient had the potential to reduce emissions by 19 percent by 2030, and changing building plans to make new houses energy efficient would reduce emissions by 6 percent.

In terms of transportation, running similar emission simulations found that a federal mandate increasing fuel efficiency to 54.5 miles per gallon would reduce carbon emissions by 38 percent.  

It’s important to note that the results of the study vary from city to city.  

The researchers add that it will be up to each city to find the best courses of action to reduce climate change, but the research indicates that reductions are possible with just a few policy changes.

To say politics these days has become divisive is an understatement. Whether it’s sports games, public restrooms, or television shows, virtually no place is safe from the unprecedented political polarization. But what exactly is fueling the divide?

A new study, conducted by researchers at <a href="https://www.byu.edu/">Brigham Young University</a> and <a href="http://www.lsu.edu/">Louisiana State University</a>, found that the current polarization is partly driven by politicians who use violent rhetoric. 

"Even if it's metaphorical, and everyone knows it, there's something that happens when you frame things in terms of battle or war that has real-world consequences," said Josh Gube, a professor at Brigham Young University.

The study was published in the journal Political Communication and shows that even a small shift in tone, using words like “battle” and “fight” instead of “work” or “struggle,” can heighten emotions and increase polarization. 

For the study, researchers asked both Republicans and Democrats to read statements on policy issues with some of the <a href="https://www.earth.com/news/donald-trump-vs-environment/">politicians</a> using words like “fight” and others using words like “effort.” 

The research team then measured political support for those policies among constituents. 

The results showed that violent metaphors drove a wedge between political supporters with a polarization effect of 20 percent. 

According to the researchers, politicians often feel using war metaphors are necessary to engage and rally their supporters. But on the other hand, such rhetoric drives non-supporters further and further away. 

Media and news outlets also further push polarization by mirroring the language and tone of the politicians they cover.

To remedy the divide, the researchers suggest that politicians forgo the mass campaigns with violent rhetoric and instead use a strategy known as “micro-targeting.” 

"If you can restrict your use of that language or the reception of that language to people that are just on your side, then you have the ability to push in one direction on political issues," said Nathan Kalmoe, one of the co-authors of the study and a professor at Louisiana State. 

Another important aspect of the study is understanding how the voter is manipulated by the constant use of violent rhetoric in politics.

If politicians can tone their rhetoric down, the researchers note, and save the heightened speeches for a micro-targeted audience, then ideally that pattern would trickle down through news coverage also taking a more neutral tone.

In the past, there was some belief among scientists and the general public that frequent marijuana use may decrease an individual’s sexual desire or performance. Now, a new study published in the <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1743-6109">Journal of Sexual Medicine</a> has found strong evidence that the effect of marijuana use might actually be the opposite.

“Frequent marijuana use doesn’t seem to impair sexual motivation or performance. If anything, it’s associated with increased coital frequency,” says Dr. Michael Eisenberg, the study's senior author and assistant professor of urology at <a href="http://med.stanford.edu/">Stanford University</a>.

According to the National Institute on Drug Abuse, over 20 million adult Americans currently use marijuana, and with the legalization of <a href="https://www.earth.com/news/cannabis-sleep-users/">cannabis</a> for medical or recreational use in 29 states, that number is only getting higher (no pun intended).

This study was the first to examine the relationship between cannabis use and frequency of sexual intercourse at the population level in the U.S., surveying over 50,000 men and women, ages 25-45. The researchers used the National Survey of Family Growth, which provides data related to family structures, sexual practices, and child bearing.

They found that 24.5 percent of men and 14.5 percent of women reported using marijuana in the previous four weeks, and there was a strong correlation between increased marijuana use and increased sexual intercourse in that time period. In fact, cannabis users reported having roughly 20 percent more sex than non-users.

"The overall trend we saw applied to people of both sexes and all races, ages, education levels, income groups and religions, every health status, whether they were married or single and whether or not they had kids,” Eisenberg adds. Furthermore, this was still the case when the researchers accounted for other substance use, which shows that this correlation isn’t necessarily due to these individuals simply being less inhibited.

Although a significant correlation was found between increased marijuana usage and sexual activity, it doesn’t mean that this study established a causal link. In other words, Eisenberg cautions, “it doesn't say if you smoke more marijuana, you’ll have more sex.” So you should probably put down your car keys and go back to sitting on the couch – the pot shop can wait.

Study finds that more marijuana use means more sex

How great are dogs? It’s hard to find someone who doesn’t love them, or at least appreciate the role of the dog in our daily lives. There are so many reasons to enjoy their existence, and scientists may have just found a couple more.

Two studies presented at the American College of Allergy, Asthma, and Immunology (ACAAI) Annual Scientific Meeting found that the presence of a dog in a child’s home may help protect them against eczema and asthma.

One study found that babies born in a home with a <a href="https://www.earth.com/news/dogs-expressive-looking/">dog</a> during pregnancy get the benefit of added protection from allergic eczema. “Although eczema is commonly found in infants, many people don’t know there is a progression from eczema to food allergies to nasal allergies and asthma,” says Dr. Gagandeep Cheema, an allergist and lead author of the study. “We wanted to know if there was a protective effect in having a dog that slowed down that progress.”

Through examining mother-child pairs that were exposed to a dog before birth, the researchers found that this exposure is associated with a lower risk of eczema by the time the child is 2-years-old. However, this protective effect goes down at the age of 10.

For the second study, researchers analyzed the effects of two separate types of dog exposure to children with asthma in Baltimore, MD. The first type was a protein, or allergen, that affects children who are allergic to dogs. The second type were elements that the dog might carry, such as bacteria. Ultimately, the results showed that exposure to elements that a dog may carry could have protective effects against asthma symptoms for the child. However, exposure to the allergen protein may increase asthma symptoms among urban children with a dog allergy.

“Among urban children with asthma who were allergic to dogs, spending time with a dog might be associated with two different effects,” says Dr. Po-Yang Tsou, the lead author of the study. “There seems to be a protective effect on asthma of non-allergen dog-associated exposures, and a harmful effect of allergen exposure.”

Both of these studies show that there seem to be even more benefits to living with dogs than we even imagined – it almost seems too good to be true.

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



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



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



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



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



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



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



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



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



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



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

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



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



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

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



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



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

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



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



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



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

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;

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;

Satellites reveal how Earth's systems are interconnected

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 <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> some of the most incredible waves in the world, as seen by Landsat satellites.



"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."
