Researchers examined the daily diets of more than 16,000 people to compare the climate impact and nutritional value of what America eats in a day. They found that diets that were more climate-friendly were also healthier.
As local newspapers shutter across the country, the residents residing in those counties without sources of local news are forced to rely more heavily on national media outlets that report political news primarily through the lens of the perennial two-party political conflict.
Greenland is melting faster than scientists previously thought—and will likely lead to faster sea level rise—thanks to the continued, accelerating warming of the Earth’s atmosphere, a new study has found.
A study by researchers from Sweden and Hungary shows that white, painted stripes on the body protect skin from insect bites. It is the first time researchers have successfully shown that body-painting has this effect. Among indigenous peoples who wear body-paint, the markings thus provide a certain protection against insect-borne diseases.
The overabundance of fast fashion — readily available, inexpensively made clothing — has created an environmental and social justice crisis, claims a new paper from an expert on environmental health at Washington University in St. Louis.“From the growth of water-intensive cotton, to the release of untreated dyes into local water sources, to worker’s low wages and poor working conditions, the environmental and social costs involved in textile manufacturing are widespread,” said Christine Ekenga, assistant professor at the Brown School and co-author of the paper “The Global Environmental Injustice of Fast Fashion,” published in the journal Environmental Health.
A new study to be published online in the journal Sleep Health reveals that late-night social media use by NBA players is linked to poorer next-day performance on the court. The study examines more than 37,000 tweets and builds on preliminary research from 2017 about late-night tweets.
The first high-quality ancient DNA data from Central and South America reveals two previously unknown genetic exchanges between North and South America, one representing a continent-wide population turnover Findings link the oldestCentral and South American samples with the Clovis culture, the first widespread archaeological culture of North America; however, this lineage disappeared within the last 9,000 years Analyses show shared ancestry between ancient Californians from the Channel Islands and groups that became widespread in the southern Peruvian Andes by at least 4,200 years ago
Beatboxing is a musical art form in which performers use their vocal tract to create percussive sounds, and a team of researchers is using real-time MRI to study the production of beatboxing sounds. Timothy Greer will describe their work showing how real-time MRI can characterize different beatboxing styles and how video signal processing can demystify the mechanics of artistic style. Greer will present the study at the Acoustical Society of America's 176th Meeting, Nov. 5-9.
Could microbes in our guts be sending out the wrong message? Queen’s University researchers have, for the first time, found a specific microbe in the gut that pumps out protein molecules that mimic a human protein, causing the human defence system to turn on its own cells by mistake.
In a new paper published in Nature, three University of Chicago scientists estimate that given how quickly LIGO researchers saw the first neutron star collision, they could have a very accurate measurement of the rate of the expansion of the universe within five to ten years.
On top of rising sea levels, stronger hurricanes and worsening wildfires, scientists project that human-caused climate change will result in one of the most dire consequences imaginable: a disruption in the global beer supply.
New research from Binghamton University, State University at New York finds that showing compassion to subordinates almost always pays off, especially when combined with the enforcement of clear goals and benchmarks.
Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers – mindfulness.
A study examined anxiety, depression, social withdrawal, and submissiveness to predict the end of teen friendships. Do friendships end because of one child’s mental health problems or do they end because of differences between friends on the degree to which each friend suffers from these problems? A key finding shows that children’s personal struggles need not adversely impact their social relationships, and mental health issues do not necessarily ruin their chances of making and maintaining worthwhile friendships.
Proponents of “terraforming” Mars to make it habitable propose releasing greenhouse gases from the planet’s surface such as carbon dioxide (CO2) to trap heat, warm the climate and ultimately increase the atmospheric pressure. The plausibility of achieving this with current technology is the focus of a new study sponsored by NASA just published in Nature Astronomy.
NASA’s Hubble Space Telescope has photographed Saturn and Mars near their closest approaches to Earth in June and July 2018. It’s now summertime in Saturn’s northern hemisphere and springtime in Mars’ southern hemisphere. The Hubble images show that Earth isn’t the only planet where intense spring and summer storms wreak havoc.
Researchers at Binghamton University, State University at New York have used a new image-based analysis technique to identify once-hidden North American mounds, which could reveal valuable information about pre-contact Native Americans.
For the first time, scientists from Lawrence Livermore National Laboratory and five other organizations have shown that human influences significantly impact the size of the seasonal cycle of temperature in the lowest layer of the atmosphere.
Fossils of a new genus and species of an ankylosaurid dinosaur—Akainacephalus johnsoni-- have been unearthed in Grand Staircase-Escalante National Monument in southern Utah, U.S.A., and are revealing new details about the diversity and evolution of this group of armored dinosaurs.
Postmenopausal factors may have an impact on the heart-protective qualities of high-density lipoproteins (HDL) – also known as ‘good cholesterol.’ The findings bring into question the current use of total HDL cholesterol to predict heart disease risk.
In a study that challenges scientists preconceptions about the global carbon cycle, researchers find that tiny organisms deep in the ocean's twilight zone may play an outsize part in the circulation of carbon.
University of Delaware management professor Kyle Emich, whose research explores the effects of emotions on teams and performance, discusses the influence emojis can have on productivity and innovation in the workplace.
Mental health and substance abuse issues in adolescents have become major societal problems, forcing parents and health providers to look for innovative treatment options that may better suit some teens. However, some proven therapy programs, like Outdoor Behavioral Healthcare (OBH), can be challenging to access because many are not covered by insurance companies – creating an enormous cost burden for parents. Now, a landmark study by researchers at the University of New Hampshire has found that parents of youth who went through an outdoor behavioral program report that their children showed almost three times the improvement after one year than youth who remained in their communities for more traditional treatment.
Fish that ‘farm’ their own patches of seaweed alter their ‘cropping’ practices under high CO2 conditions, researchers at the University of Adelaide in Australia have found.
New research links outdoor air pollution — even at levels deemed safe — to an increased risk of diabetes globally, according to a study from Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.
As the United States celebrates its founding on July 4, new research on “collective narcissism” suggests many Americans have hugely exaggerated notions about how much their home states helped to write the nation’s narrative.“Our study shows a massive narcissistic bias in the way that people from the United States remember the contributions of their home states to U.
Using ancient dog DNA and DNA from modern village dogs, University of Michigan researchers find new genetic sites that may be responsible for important domestication traits--sites that are also connected to rare genetic syndromes in people.
Exercise may be just as crucial to a depression patient’s good health as finding an effective antidepressant.
Those cute little whiskers you see on your pet do more than just twitch adorably. Intrigued by the hairs’ versatility, University of Texas at Dallas researchers used shape-memory polymers to create artificial, electronic versions called e-whiskers, which mimic the properties of the real thing.
A new University of Washington-led paper pinpoints starvation as the cause of death for hundreds of thousands of Cassin's auklet seabirds in late 2014 to early 2015.
A new study that reconstructs the deep history of our planet’s relationship to the moon shows that 1.4 billion years ago, a day on Earth lasted just over 18 hours. This is at least in part because the moon was closer and changed the way the Earth spun around its axis.
A 21-gene test could enable most patients with the most common type of early breast cancer to safely forgo chemotherapy, according to a landmark study published in the New England Journal of Medicine. Loyola Medicine oncologist Kathy Albain, MD, is among the main co-authors.
Scientists report they have uncovered a previously overlooked connection between neurons in two distinct areas of the mammalian brain. The neurons, they say, control the sense of touch, and their experiments in mice offer insights into mapping brain circuitry that is responsible for normal and abnormal perception and movements linked to touch.
A study in Science offers an explanation for a mysterious and sometimes deadly weather pattern in which the jet stream, the global air currents that circle the Earth, stalls out over a region. Much like highways, the jet stream has a capacity, researchers said, and when it’s exceeded, blockages form that are remarkably similar to traffic jams—and climate forecasters can use the same math to model them both.
A new study has quantified, for the first time, the relationship between lack of paid sick leave and poverty in the U.S. The data indicates that, even when controlling for education, race, sex, marital status and employment, working adults without paid sick leave are three times more likely to have incomes below the poverty line. People without paid sick leave benefits also are more likely to experience food insecurity and require welfare services.
Sweet potatoes may seem as American as Thanksgiving, but scientists have long debated whether their plant family originated in the Old or New World. New research by an Indiana University paleobotanist suggests it originated in Asia, and much earlier than previously known.
A team of researchers led by Lawrence Livermore National Laboratory has developed a second way to use protein markers from human tissue to identify people – this time from human bones.
Harvard Medical School researchers lead the first whole-genome analysis of ancient human DNA from Southeast Asia Study identifies at least three major waves of human migration into the region over the last 50,000 years, each shaping the genetics of Southeast Asia “to a remarkable extent” Findings reveal a complex interplay among archaeology, genetics and language
The researchers examined 17 years of transplantation records and found no significant change in the recipients’ chance of survival when the organ donation came from victims of drug intoxication. The study publishes online on May 17 in the New England Journal of Medicine.
People with mild asthma are often prescribed a daily treatment regimen, but up to 80 per cent do not follow the routine, using inhalers only when they have an asthma attack. Now the researchers have found an as-needed combined-drug inhaler is a viable treatment option.
Corporate programs aimed at offsetting the negative societal impacts caused by their profit-seeking tend to devalue the very people they intend to help.
The annual meeting of the Society for Academic Emergency Medicine (SAEM). The SAEM 2018 meeting will bring together more than 3,000 physicians, researchers, residents and medical students from around the world.
Mechanical engineering researchers have developed a method that could extend the life of an artificial hip by adding an array of microscopic indentations that increase the thickness of a lubricating film on its surface.
The Clarkson Student Projects for Engineering Experience and Design Team won 1st place in a regional competition.
Scientists are now working to take cloaking devices from the dramatic realm of science fiction and make them real. Amanda D. Hanford, at Pennsylvania State University, is taking the introductory steps to make acoustic ground cloaks. These materials redirect approaching waves around an object without scattering the wave energy, concealing the object from the sound waves. During the 175th ASA Meeting, Hanford will describe the physics behind an underwater acoustic shield designed in her lab.
Four NASA spacecraft have observed magnetic reconnection in a turbulent region of the Earth's outer atmosphere known as the magnetosheath, the planet's first line of defense against the intensity of solar wind. The new insights could help us understand how such phenomena affect Earth's atmosphere.
New research from the Keck School of Medicine of USC reveals how traumatic noise damages hearing and identifies a potential way to preserve it
Sympathetic nerve activity to skeletal muscle blood vessels—a function of the nervous system that helps regulate blood pressure—increases during physiological and mental stress in people with chronic anxiety, a new study finds.
A new poll busts stereotypes about the sex lives of older Americans – and reveals gender and health-related divides on key aspects of sexual health, while highlighting the need for more people to talk with their health providers about sexual issues.
