Isn't it bizarre how many times we've been told that a glass of wine a day keeps the doctor away? Or some variation of that claim on benefits of moderate drinking. 



Well, a new research has come to light, and it might alter the way you perceive that glass of Cabernet Sauvignon or pint of IPA in your hand.



The report is shaking up the conventional wisdom we've heard for years--that moderate drinking could extend lives and decrease our chances of chronic diseases. 



Steering this riveting ship of discovery is lead researcher Tim Stockwell, Ph.D., a scientist affiliated with the <a href="https://www.uvic.ca/research/centres/cisur/index.php" target="_blank" rel="noreferrer noopener">Canadian Institute for Substance Use Research</a> at the University of Victoria.



<h2 class="wp-block-heading" id="h-past-studies-on-moderate-drinking">Past studies on moderate drinking</h2>



Stockwell and his team argue that there are underlying flaws in the way previous researches have been designed. 



They believe that the studies' focus on older adults without considering their <a href="https://www.earth.com/news/alcohol-has-a-hidden-impact-on-heart-health/" target="_blank" rel="noreferrer noopener">lifetime drinking habits</a> led to skewed results.



"Think about this for a second. When these studies compare moderate drinkers with abstainers, many of the abstainers are older adults who have quit or reduced their drinking due to health conditions," Stockwell remarked. 



"This situation makes the continued drinkers appear healthier, but it's a rigged comparison. It's like comparing apples with oranges."



In other words, things are not what they seem when it comes to these studies.



<h2 class="wp-block-heading" id="h-truth-about-alcohol-consumption">Truth about alcohol consumption</h2>



For this analysis, Stockwell and his team examined 107 published studies that followed individuals over time and explored the relationship between drinking habits and lifespan.



A quick look at the data suggested something that might ring a bell: moderate drinkers (those who drank between one drink per week and two per day) had a 14% lower risk of dying during the study period compared to abstainers. However, a closer examination of the studies told a different story.



Stockwell pointed out that the "higher quality" studies - those that considered younger participants and ensured a clear distinction between former drinkers and lifelong abstainers - showed no link between moderate drinking and longer lives.



The illusion of health benefits came only from the "lower quality" studies. Stockwell quipped, "If you look at the weakest studies, that's where you see supposed health benefits."



<h2 class="wp-block-heading" id="h-paradox-of-perception">Paradox of perception</h2>



In our social constructs, drinking often takes on an additional layer of meaning, transformed into a communal activity that fosters connection. Yet, this context can also mask the true implications of alcohol consumption on health. 



Many individuals justify their drinking habits with social norms, failing to recognize the potential harm. 



Stockwell's research underscores the importance of examining how societal attitudes towards drinking can buoy the perception of its health benefits, leading to an environment where moderation may not be as beneficial as previously thought. 



We need to reassess not just our protocols for studying alcohol but also the culture around it.



<h2 class="wp-block-heading" id="h-public-awareness-on-moderate-drinking">Public awareness on moderate drinking</h2>



Given these revelations, there is an urgent need for public health campaigns to rethink their messaging about alcohol consumption. 



Instead of perpetuating the myth that moderate drinking has health benefits, stakeholders should emphasize the risks tied to alcohol and encourage a more informed dialogue around healthy lifestyles. 



By promoting comprehensive education on the potential dangers of drinking, the goal should be to empower individuals to make more educated choices regarding their alcohol consumption. 



It’s time to break away from outdated perceptions and embrace a modern understanding of alcohol’s role in our health, fostering a culture of awareness rather than <a href="https://www.earth.com/news/are-zero-alcohol-drinks-a-type-of-gateway-drug-for-teens/" target="_blank" rel="noreferrer noopener">complacency</a>.



<h2 class="wp-block-heading" id="h-busting-myths">Busting myths</h2>



One myth that Stockwell wants to debunk is the decades-old belief in the "French Paradox." This notion suggests that red wine explains why French people have significantly lower rates of heart disease despite having a diet high in fats. 



It's a compelling story, but Stockwell argues that the concept is a mere figment of the public imagination.



According to Stockwell, moderate drinking likely doesn't extend our lives. In fact, it can bring along a suitcase of <a href="https://www.earth.com/news/alcohol-consumption-can-lead-to-chronic-pain/" target="_blank" rel="noreferrer noopener">health risks</a>, such as increased chances of developing certain cancers.



"There is simply no completely 'safe' level of drinking," Stockwell stressed.



So, the next time you hear that familiar saying about a glass of wine a day, remember: <a href="https://www.earth.com/news/heart-benefits-of-moderate-drinking-may-be-hidden-in-the-brain/" target="_blank" rel="noreferrer noopener">what the doctor ordered</a> has been reconsidered. 



New evidence prompts us to reassess our drinking habits and encourages us towards a more informed and healthier future, even if it's with a little less wining and dining. Cheers to that!

Even moderate drinking severely harms health, despite past studies

Isn't it bizarre how many times we've been told that a glass of wine a day keeps the doctor away? Or some variation of that claim on benefits of moderate drinking. Well, a new research has come to light, and it might alter the way you perceive that glass of Cabernet Sauvignon or pint of IPA in your hand.

Europe has twice as many diesel vehicles as the rest of the world combined, and it could be taking a bigger toll on public health than previously believed.

A team of researchers from the <a href="http://www.iiasa.ac.at/">International Institute for Applied Systems Analysis</a> in Austria, <a href="http://www.chalmers.se/en">Chalmers University of Technology</a> in Sweden and the <a href="https://www.met.no/en">Norwegian Meteorological Institute</a> have conducted a new study to find out how the air pollution produced by diesel vehicles in Europe may contribute to the annual pollution-related deaths on the continent. 

They found that emissions from diesel cars, trucks, buses and other vehicles may be linked to as many as 10,000 premature deaths per year. Half of those deaths may have been prevented if laboratory testing of diesel vehicle emissions had been accurate, the scientists said.

“Modern engine controls have been optimized by manufacturers for the specific laboratory testing but underperform in real-driving,” the scientists said, referring to <a href="https://www.earth.com/news/vehicle-emissions-worse-testing/">earlier research on diesel emissions</a>.

About 425,000 deaths in Europe are linked to air pollution each year, the researchers said in a press release. The vast majority of those deaths – about 90 percent – stem from cardiovascular or respiratory diseases linked to nitrogen dioxide and nitric oxide, abbreviated NOx, the scientists said.

The problem is exacerbated by Europe’s large number of diesel cars, trucks and other automobiles. Diesel vehicles have been found to produce up to <a href="https://www.earth.com/news/nitrogen-oxide-diesel-car/">10 times more NOx than buses</a> despite being substantially smaller.

"If diesel car emissions were as low as petrol car emissions, three quarters or about 7,500 premature deaths could have been avoided," said Dr. Jens Borken-Kleefeld, a transportation expert for the IIASA.

The vast majority of the premature deaths are in France, Germany and Italy, the researchers said. However, due to other types of air pollution and other environmental factors, the risk per capita is much higher in northern Italy, they said.

The study will be published in the journal <a href="http://iopscience.iop.org/erl">Environmental Research Letters</a>.

A new study has found that Islamophobia is about more than just the religion, and is rooted in racism and cultural intolerance.

According to the research, even though Muslims are not a race, American Muslims and non-Muslims in the United States face the same sorts of profiling and bias associated with racism. 

Authored by Craig Considine from <a href="http://www.rice.edu/">Rice University</a>, the paper cited examples of academic studies and more than 40 news articles that discussed the experiences of American Muslims and depictions of Muslims in the media. 

Considine’s paper concludes that Islamophobia is not just a form of religious bias, but in fact,  “race is endemic to Islamophobic incidents.”

The media and pop culture have been particularly apt at portraying Muslims in a negative light, thereby grouping all Muslims into one harmful racial stereotype that usually portrays Arab/Muslims as nefarious, bearded, dark-skinned and usually wearing a turban. 

U.S. President <a href="https://www.earth.com/news/donald-trump-vs-environment/">Donald Trump</a> has exacerbated this effect in his comments on the religion, telling <a href="http://www.cnn.com/">CNN</a>, “I think Islam hates us.”

Crimes by Muslims are given 449 percent more news coverage than crimes carried out by non-Muslims. 

Of more than 1,000 Hollywood films depicting Arabs, only twelve of the films had positive portrayals of Arabs/Muslims. 

“Despite the racial, ethnic and cultural diversity of the U.S. Muslim population, they continue to be cast as potentially threatening persons based on perceived racial and cultural characteristics,” said Considine. 

The racialization of Islam has created a rash of hate crimes against Muslims. For example, one of the hate crimes Considine cites in his paper is the shooting of a Sikh in Mesa, Arizona after September 11th. 

The man who shot him wanted to just “kill a Muslim” in retaliation for terrorist attacks. Even though Sikhism is not connected to Islam, the Sikh was targeted and profiled because of his appearance and turban. The man who shot him identified the Sikh by the media’s racial stereotypes. 

“This incident and other incidents referenced in the paper are examples of how Muslims have been racialized and thus subjected to a kind of racism,” Considine said. 

Between 2010 and 2014, more than fifty percent of Muslims reported experiencing some form of hostility, bias, or felt targeted because they were identified as Muslim. 

Simply classing Islamophobia as not a type of racism does a great disservice, and as Considine proves, is detrimental to the well-being and safety of Muslim Americans and Muslims in the United States. 

“We would be misguided to dismiss the role that race plays in incidents where Muslims and non-Muslims are targeted due to stereotypes of 'Muslim identity, this identity, insofar as the American context goes, appears to be weighted with racial meanings,” said Considine. 

The study was published in the journal Religions.

A new study found that failure can help motivate you to do better in the future, but the key is how you process your missteps. 

Inherently, humans distance themselves from the uncomfortable feelings associated with failure. Growing up, we are told that dwelling on failure isn’t productive or healthy. But new research finds that allowing yourself to experience the full brunt of feelings after a failure can be a great source of encouragement to improve.

The research was conducted by Selin Malkoc from <a href="https://fisher.osu.edu/">Ohio State University's Fisher College of Business</a>, Noelle Nelson of the <a href="https://www.ku.edu/">University of Kansas</a> and Baba Shiv of <a href="https://www.stanford.edu/">Stanford University</a>. 

The authors found that emotion was the important determining factor in the learning process.

“When faced with a failure, it is better to focus on one's emotions—when people concentrate on how bad they feel and how they don't want to experience these feelings again, they are more likely to try harder the next time,” said Malkoc.

The researchers asked <a href="https://www.earth.com/news/college-binge-drinking-brain-activity/">college students</a> to participate in several studies that would weigh emotions and cognitive thinking in the face of failure. 

In one experiment, the students were asked to search online for the lowest prices blender, if they found the lowest price they could win a prize. But the experiment guaranteed all participants would fail. 

Before finding out if they won or not, the researchers asked half of the students to focus on their emotional response to losing, and the other half were instructed to think about how they thought they did. In other words, one group was asked to look at the emotional ramifications of losing, and the other had a more cognitive response to an unknown outcome. 

After several similar experiments, the researchers found that emotions were a better motivator than cognitive responses. 

“When the participants focused on how bad they felt about failing the first time, they tried harder than others when they had another similar opportunity,” said Malkoc. 

The study shows that dwelling on failure can have a positive effect, even though focusing on painful and embarrassing emotions correlated with failure can be difficult.

Fall is in the air, and it is the perfect time of year to enjoy the great outdoors. According to the <a href="https://www.rvda.org/RVDA/Media/News_Releases/2017_News_Releases/March_2017/Camping.aspx">2017 North American Camping Report</a>, 75 million households in the United States are active campers. Half of those families say they plan to <a href="https://www.earth.com/video/insomnia-cure-camping/">camp</a> more this year. 

Whether you are an experienced camper or just someone that looks forward to pitching a tent every now and then, it is simple to get outside and enjoy the beauty of nature. The following is a list of the 8 most amazing places to camp in the United States.

Glacier National Park 

Located in Montana on the US/Canada border, this park features more than a million acres, including mountains that began forming 170 million years ago. Featuring 130 named lakes, over 1,000 different species of plants, and hundreds of species of animals, this is one of the prime locations in the country to experience life outside.

Acadia National Park

With its 17 million acres of forest, 6,000 lakes and ponds, and 32,000 miles of rivers and streams, Maine has an abundance of biodiversity. Located on Mount Desert Island, this park encompasses everything the state has to offer including Cadillac Mountain, an incredible hiking spot that towers over the site at 1,530 feet.

Little Tybee Island

Just a short boat ride south of Tybee Island, Georgia, this is the perfect spot to sleep under the stars. The island has a number of endangered species of birds, rich salt marshes, and natural dunes. This wildlife reserve is twice the size of Tybee, yet completely uninhabited.

Shenandoah National Park

This breathtaking site in Virginia is only a short drive from Washington D.C. that features over 500 miles of hiking trails with access to gorgeous waterfalls and stunning views. One of the most popular trails is a nine-mile hike to Old Rag Mountain, which sits high in the Blue Ridge Mountains.

Badlands National Park  

Known for an abundance of fossil mammals, this historic area of South Dakota offers a number of great camping sites. The terrain is rugged and not the easiest to navigate, but the experience is well worth the extra effort. The Badlands are said to have the largest fossil accumulation from the Eocene and Oligocene Epochs.

Yosemite National Park

This park, located in the Sierra Nevada mountains of California, is known for its ancient sequoia trees, granite cliffs, clear streams and an incredible amount of biodiversity. Yosemite features 13 campgrounds, and the site is so iconic that it was key in the concept of national parks. 

Crater Lake National Park

Located in Oregon among the Cascade Mountain Range, this is the site of incredible volcanic formations, including Crater Lake. This lake is the deepest in the United States and is also said to be the cleanest and most pure lake in the country. The park has two developed campgrounds.

Pisgah National Forest  

This enchanted forest is known as the Land of the Waterfalls. It encompasses 500,000 acres of the Appalachian Mountains just outside of Asheville, North Carolina. Mile-high peaks offer majestic views and campers can enjoy rock climbing, backpacking, and fishing.

Ludington State Park

Located in western Michigan, Ludington State Park spans 5,300 acres and just last year celebrated its 80th birthday. Known as the most popular state park in Michigan, Ludington attracts a large number of tourists due to its widely diverse attractions, which include hiking, fishing, biking, boating, swimming, and sledding.

Arches National Park

Located in eastern Utah next to the Colorado River, Arches National Park contains over 2,000 natural sandstone arches across 76,000 acres. The majestic beauty and vibrant orange and red colors make the park a favorite for those most familiar with the southwestern United States. Although climbing on the named arches is strictly prohibited, climbing is allowed in other parts of the park, along with hiking and camping. Arches is also a popular destination for astronomers, thanks to its uniquely clear skies.

Gun control has been one of the most heated debates in the United States for decades, with the 2nd Amendment to the Constitution being weighed against the rising gun violence in many cities and the recent prevalence of mass shootings. Along with these topics, accidental shootings – particularly involving children – are also an important factor for consideration when discussing creating or changing gun laws.

New research was presented at the <a href="https://www.aap.org/en-us/Pages/Default.aspx">American Academy of Pediatrics</a> National Conference &amp; Exhibition in Chicago, which found that the regions of the U.S. with the strictest gun laws also have the lowest rates of childhood firearm injuries.

The researchers ranked each region of the U.S. using the Brady Gun Law Score, which scores states based on policy approaches to regulating both guns and ammunition. This score takes into account background checks on gun sales, reporting stolen or lost firearms, and restricting the purchase of <a href="https://www.earth.com/news/higher-suicide-rates-rural-areas/">weapons</a> among high-risk populations. The study compared these regional scores with national data from the Nationwide Emergency Department Sample from 2009-2013, which included analysis of over 100,000 emergency department visits for pediatric firearm-related injuries.

In comparing the regions’ Brady Gun Law Scores with the number of these injuries per region, the researchers found that regions with higher Brady scores (indicating stricter gun laws) also had lower rates of emergency department visits for firearm injuries among children and teens. This suggests that stricter gun laws may be related to fewer firearm injuries among youth.

Regionally, the lowest rate of firearm injuries occurred in the Northeast, which had the highest Brady score as well. The Midwest had the second lowest injury rate, the West had the third lowest, and the South was last with the highest rates of visits for pediatric firearm injuries – and also the lowest Brady score.

“Our study highlights the regional variations in gun laws,” says Dr. Monika Goyal, an assistant professor of pediatrics and emergency medicine at Children’s National Health System and <a href="https://www.gwu.edu/">The George Washington University</a>. “It also suggests how gun laws may help to reduce the number of pediatric firearm victims being treated in the emergency department each year.”

While more research on other competing factors will need to be done, this study is a step in the right direction in terms of determining what may be putting children at risk of firearm injuries. It’s safe to say we can all get on board with decreasing the number of children ending up in hospitals with gun wounds.

More and more studies are showing that access to safe, natural environments improves the overall health of children including heart health, mental health, weight management, and stress management. A new concept has emerged from this research that is known as a green schoolyard.

Stephen Pont is the medical director at <a href="https://www.dellchildrens.net/">Dell Children's Texas Center</a> and an assistant professor of Pediatrics at <a href="https://dellmed.utexas.edu/">UT-Austin Dell Medical School</a>.

"Green schoolyards can include outdoor classrooms, native gardens, storm water capture, traditional play equipment, vegetable gardens, trails, trees and more," said Dr. Pont. "And outside of school time, these schoolyards can be open for the surrounding community to use, benefitting everyone."

Green schoolyards offer <a href="https://www.earth.com/news/deportation-fears-american-children/">children</a> a healthy outdoor environment as part of their daily lives. Green schoolyards also provide value to the entire community by promoting improved health and higher rates of community and family engagement. 

Richard Louv is a co-founder of the <a href="http://www.childrenandnature.org/">Children &amp; Nature Network</a>.

"Too many children have no access to quality school grounds. In many neighborhoods, the standard play space is a barren asphalt playground or a concrete slab surrounded by chain link fence--a completely unsuitable environment for children's play,” said Louv.

In collaboration with the Children &amp; Nature Network and the <a href="http://www.nlc.org/">National League of Cities</a>, five cities have implemented green schoolyards as a result of the research. The study authors have documented green schoolyard advantages such as improved academic outcomes, physical activity, and mental health.

"So many physicians and health professionals choose to spend their free time in nature, but we often forget that nature can be a powerful health intervention for our patients, both for the prevention and improvement of many medical conditions," said Dr. Pont. "We should all be champions for kids and families getting more Vitamin N."

The research will be presented September 16th at the <a href="https://www.aap.org/">American Academy of Pediatrics</a> National Conference &amp; Exhibition in Chicago. The concept will be presented as, "Green Schoolyards Support Healthy Bodies, Minds and Communities.”

It has been estimated that up to one-third of young North Americans and Europeans partake in binge drinking, particularly during their college years.

Binge drinking, as described by <a href="https://www.niaaa.nih.gov/">The National Institute of Alcohol Abuse and Alcoholism</a>, occurs when 4 to 5 drinks are consumed in a two-hour period. 

Both binge drinking and alcoholism have been scientifically proven to affect brain activity. But for college students specifically, binge drinking has been linked to poor performance in school, neurocognitive deficits, and risky sexual behavior, not to mention the risks involved with alcohol poisoning and drunk driving  

Researchers in Spain and Portugal set out determine if binge drinking had any impact on the brain activity of college students while at rest. 

“A number of studies have assessed the effects of binge drinking in young adults during different tasks involving cognitive processes such as attention or working memory. However, there are hardly any studies assessing if the brains of binge drinkers show differences when they are at rest, and not focused on a task, “ said Eduardo López-Caneda from the<a href="https://www.uminho.pt/EN"> University of Minho</a> in Portugal and one of the researchers. 

Researchers asked first-year college students to take a survey about their drinking habits. If the student had partaken in binge drinking in the last month. The researchers then attached electrodes to the students and observed electrical activity in the different parts of the brain while at rest. 

The results showed different brain activity in the students labeled as binge drinkers. These students had higher measurements of beta and theta oscillations in the right temporal lobe and bilateral occipital cortex. These results are similar to the brain activity of chronic alcoholics. 

Because adolescent brains are still developing, it is especially dangerous that young binge drinkers display brain activity similar to the damage done to older adult alcoholic brains.

Lopez-Caneda stresses the importance of future studies factoring in this research to see just how much brain activity can be affected by binge <a href="https://www.earth.com/news/men-harder-quitting-drinking/">drinking</a> at a young age. 

The study was published in the journal, Frontiers in Behavioral Neuroscience.

Feeling alone may have a negative effect on your overall well-being, according to a new study. Researchers found that new university students consistently think their peers have more friends and a more active social life than they have. Even when this is not the case, <a href="https://www.earth.com/news/college-sporting-venues-zero-waste/">students</a> who believe it to be true feel less accepted.

Ashley Whillans is an assistant professor at <a href="http://www.hbs.edu/">Harvard Business School</a> who led the study while she was a PhD candidate at the <a href="https://www.ubc.ca/">University of British Columbia</a>.

"We know the size of your social networks has a significant effect on happiness and wellbeing," said Whillans. "But our research shows that even mere beliefs you have about your peers' social networks has an impact on your happiness."

The research team collected data from a survey of over 1,000 first-year students at the University of British Columbia. Students reported how many friends they had made and estimated how many friends they believed their peers had made since the beginning of the school year. The study revealed that 48 percent of the students believed others had developed more close friendships, while 31 percent believed the opposite. 

A second survey tracked 389 students until the end of their first year. The students who believed that they had less friends than their peers at the beginning of the year reported lower levels of wellbeing.

Senior author Frances Chen said that the public nature of social activities may explain why students feel their peers are doing better socially.

"Since social activities, like eating or studying with others, tend to happen in cafes and libraries where they are easily seen, students might overestimate how much their peers are socializing because they don't see them eating and studying alone," said Chen.

According to Chen, further research is needed to determine whether the same pattern exists in other circumstances, such as with new immigrants, people moving to a new city, or people starting a new job.

"These feelings and perceptions are probably the strongest when people first enter a new social environment, but most of us probably experience them at some point in our lives," said Chen.

Repealing the Affordable Care Act (ACA), otherwise known as Obamacare, would likely leave many veterans uninsured, and demand for Veterans Affairs (VA) health care would surge, according to a recent report from the RAND corporation, a nonprofit research organization. 

Many veterans rely on VA health care and are more likely to be insured than non-veterans. Those most impacted by new legislation to repeal would be older, low income, and less healthy veterans. 

In 2013, it was recorded that one in ten non-elderly veterans were not insured and did not have VA coverage. VA health care will likely be faced with an influx of those seeking care if health coverage changes and would find their resources strained because of it. 

“Some veterans who lose health insurance coverage as a result of ACA repeal will become more likely to seek care from the VA health system, leading to additional strain on a health care system that already faces challenges in ensuring adequate capacity,” said Michael Dworsky, lead author of the study and RAND economist. 

Not all <a href="https://www.earth.com/news/cannabis-treatment-chronic-pain/">veterans</a> are eligible for VA care, and even those that are don't always enroll in the program. Veterans who do enroll in the VA health system may still seek treatment elsewhere for many reasons. 

Due to these variables, any changes in non-VA health insurance, like Obamacare, will majorly impact veterans and the VA. 

The researchers assessed the possible ramifications of changes to the ACA by looking at how many veterans received health care and the source of care. Once they had enough data, they projected how coverage for veterans would have been affected if the ACA had been repealed or changed in 2015. 

The ACA reduced the numbers of uninsured veterans and VA-covered veterans who lacked non-VA insurance, and according to the research,m any future changes or a repeal would impact both the VA and veterans on a broad scale.

Study: Repealing Obamacare would leave veterans uninsured

Repealing the Affordable Care Act (ACA), otherwise known as Obamacare,...

An extensive 25-year study found undeniable undercurrents of sexist media coverage and misogyny against women in sports. The study focused on sports coverage and commentators to show not just the prevalence of sexism in sports news, but also how the language and tone of sexism have changed. 

Commentators tend to cover women’s sports with bland narration, making it appear to spectators that women’s sports just aren’t as exciting as men’s sports. 

The study also found that for news coverage, highlights and news updates for women’s sports had almost 50% less airtime. 

Cheryl Cook from <a href="http://www.purdue.edu/">Purdue University</a> conducted the study along with Michela Musto and Michael A. Messner from the <a href="https://www.usc.edu/">University of Southern California</a>. The research was published in the journal, Gender &amp; Society. 

Starting in 1989, every five years, the researchers analyzed six weeks of sports news on three Los Angeles network stations and three weeks of ESPN’s SportsCenter.

One interesting aspect of conducting such a long reaching study was observing how the language and tone of sexism changed in sports news. For example, in the 1990’s coverage of women’s sports was rife with blatant misogyny, linking the female players to society's conventional gender roles of mothers and wives. 

The most recent data from 2014 shows a tonal shift in sports commentators, covering games with bland and lackluster air. The researchers call this “gender bland sexism” because it subconsciously makes the viewer think women’s sports are not as exciting. 

“Sports news shows now disguise sexism in their 'matter-of-fact' reactions to women athletes' performance, subtly sending viewers the message that women's sports lack the excitement and interest of men's sports,” the researchers wrote. 

A breakdown of the data collected in 2014 reveals that women’s <a href="https://www.earth.com/video/rubber-sports-possible/">sports</a> get nearly 50% less air time for news stories. While sports commentators take on a fast-paced, joking, and rousing tone when covering men’s sports, female athletes and coaches get fewer interviews, and there is less replay of game footage and highlights of exciting plays. 

“The stubborn persistence of the lower quantitative coverage and the poor production values serve as key to marginalizing women within the male-dominated, male-controlled institution of sport,” said the authors.

Sexist media coverage of women’s sports influences reception

An extensive 25-year study found undeniable undercurrents of sexist media...

According to the <a href="https://www.cdc.gov/nchs/products/databriefs/db241.htm">CDC</a>, from 1999 and 2014, the suicide rate jumped 24%, from 10.5 to 13.0 per 100,000 people. More specifically, the rate of suicide attempts has especially increased in younger adults with only a high school education and in those with previously diagnosed mood, anxiety, and personality disorders.

Sunday, September 10th was World Suicide Prevention Day, and September is Suicide Prevention Awareness month. It is a time to raise awareness, encourage communication, and help those affected by <a href="https://www.earth.com/news/higher-suicide-rates-rural-areas/">suicide</a>. 

A new report published in the journal JAMA Psychiatry examined the circumstances that most influenced suicide risk factors.

The authors collected data from two surveys that asked 69,341 adults in the U.S. questions about the occurrence and timing of suicide attempts.

Suicide attempts increased in adults from .62 percent in 2004 through 2005 to .79 percent in 2012 through 2013. The surveys also showed that most of the suicide attempts had been women under the age of 50.

The risk of a suicide attempt increased with adults aged 21-34, with those who lacked a formal college education, and in adults who had antisocial personality disorders, a history of violent behaviors, or a history of anxiety or depressive disorders.  

“The pattern of suicide attempts supports a clinical and public health focus on younger, socioeconomically disadvantaged adults, especially those with a history of suicide attempts and common personality, mood and anxiety disorders,” the study reported.

Many patients who suffer from chronic pain, post traumatic stress disorder, or insomnia use cannabis-based medicines for sleep. But now, clinical research from the <a href="https://umich.edu/">University of Michigan</a> warns that regular users may struggle to sleep without the drug or may build up too high of a tolerance. 

Severe or chronic pain accounts for the majority of qualified conditions for people to use medicinal marijuana in the United States, but another common reason for people to seek out a medical marijuana card is to treat insomnia. 

Despite the legalization of marijuana in 28 states, there are still many things about the drug that are unknown. Previous research on cannabis and sleep was conducted in sleep labs, where sleep stages and sleep continuity were measured. Some of these studies showed that individuals were able to fall asleep faster and stay asleep longer under the influence of cannabis.

For patients who use cannabis regularly, however, quitting the drug causes difficulty sleeping. Previous research also indicates that chronic use of <a href="https://www.earth.com/news/countries-legalize-cannabis-law/">cannabis</a> may lesson the sleep benefits overtime. To test these theories, experts set out to determine how sleep quality varies among people who never smoke marijuana, occasionally smoke, and smoke daily.

98 young males were recruited for the study. They were asked to answer surveys, keep sleep diaries, and wear accelerometers for a week. Throughout the study, the individuals were instructed to use marijuana as they normally would. The results of the study found that 39 percent of the daily cannabis users reported significant insomnia compared to only ten percent of occasional smokers.

While frequent smokers were found to actually sleep worse, the researchers also discovered that frequent smokers with anxiety and depression slept much better. The researchers ultimately determined that the effects of cannabis on sleep are highly variable.

Psychiatry Professor Deirdre Conroy said that the results of using cannabis to sleep will vary according to factors such as each individual, the type of cannabis, the concentrations of the cannabis, and the frequency of use. 

Future exploration of this topic may look into how different subspecies and concentrations of cannabis impact sleep. For example, one strain of cannabis may help sleep while another may cause nightmares.

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



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



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

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



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



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

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



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



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



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

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



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

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



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



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

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



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



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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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."

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



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



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



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



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