More than half of female elephants are being born without tusks

Scientists are starting to explore the connection between the uterus, the ovaries, and the brain to better understand how removing these organs can impact a person’s health.

Kiwi children who spend too much time on screens are becoming sicker, more obese, and more likely to be hyperactive, according to a new study. Commissioned by the Ministry of Social Development, the study also showed young children who exceeded the recommended electronic screen time had poorer motor skills than those who were less exposed to the technology.

By Christian Jarrett. Trait self-control and effective strategy use may represent two separate routes to greater persistence.

Many Americans would welcome some traits of the island’s free, universal health care system.

In literature, characters that smoke are often described as haggard and older looking, with facial features that are associated with worn leather. While these depictions arguably carry over into reality, what is for certain is that the association between smoking, cancer, and cardiovascular disease is strong. Unfortunately, however, the connection between smoking and biological aging has been less clear. Yet, a new study from an international team of investigators led by scientists at Insilico Medicine may change how smoking is evaluated at the biochemical level.

Now that the DSM lists severe hoarding as a disorder apart from OCD, psychologists are asking what explains its prevalence.

New research suggests that humpback whale populations in the Atlantic and Indian Oceans are picking up musical ideas from one another, and incorporating the new phrases and themes into their songs. According to the study, published November 28, 2018, in the peer-reviewed journal Royal Society Open Science, humpback whale populations in different Southern Hemisphere ocean basins (the South Atlantic and Indian Oceans) sing similar song types, but the amount of similarity differs across years.

Last spring, Marketplace host Charlsie Agro and her identical twin sister, Carly, bought DNA ancestry kits from five of the most popular companies in the industry. Find out why some of the results they received left a team of computational biologists at Yale University baffled.

Women that underwent extreme physical training and completed a transantarctic expedition did not show any more negative health effects than would be expected in men, according to a study presented at the Society for Endocrinology annual conference in Glasgow. The study is the first to suggest that women are not more susceptible to the negative effects of physical exertion and, that with appropriate training and preparation, can be as resilient as men in undertaking arduous physical activity.

Despite the common association of human lice with abandoned or neglected people, no procedure to assess pediculosis, aimed to detect signs of neglect, exists. Investigating the two most common forms of head louse infestation, regular and severe, we define lice-markers of neglect and develop a protocol and survey form to record and assess pediculosis. The study of head lice from a deceased victim of neglect helped unravel time-length since death, frequency of exposure to neglect and the cause and circumstances related to the death. Nit-clusters are markers of neglect, indicating length and frequency of neglect episodes.

A study was published last week by the same scientists, which stated that oceans are absorbing heat more than imaginations and estimations of the scientists. This is a major threat to the planet.

Yet whenever I post an image of a woman with a full bush, tempers flare. How did we get here? By Kate Lister.

Human beings can configure their faces in thousands and thousands of ways to convey emotion, but only 35 expressions actually get the job done across cultures, a new study has found. And while our faces can convey a multitude of emotions—from anger to sadness to riotous joy—the number of ways our faces can convey different emotions varies. Disgust, for example, needs just one facial expression to get its point across throughout the world.

Researchers say a pack of wild canines found frolicking near the beaches of the Texas Gulf Coast carries a substantial amount of red wolf genes, a surprising discovery because the animal was declared extinct in the wild nearly 40 years ago. By David Warren.

Researchers have discovered that Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a calcium ion channel impairment condition and are working on a diagnostic blood test for the disease.

While current immune checkpoint inhibitor therapies are largely ineffective against pancreatic cancer, scientists in the U.S. have now identified an immune checkpoint molecule that could represent a promising immunotherapeutic target for this tumor type. The University of Texas MD Anderson Cancer Center-led team found that V-domain immunoglobulin suppressor of T cell activation (VISTA) is preferentially expressed at high levels in pancreatic cancer, when compared with melanoma tumors.

A researcher claims that identity theft was at play in the case of Jeanne Calment, the world’s oldest person, but experts say that evidence is weak.

Current guidelines for sun exposure are unhealthy and unscientific, controversial new research suggests—and quite possibly even racist. How did we get it so wrong?

A new government report highlights just how pervasive the problem is.

The extravagant splendor of the animal kingdom can’t be explained by natural selection alone — so how did it come to be?

OK, so it was never great in the first place. But the rise of rank nationalists could finally—perversely—spark an era of progress and cooperation for all humanity.

And they react to the buzzing of pollinators by sweetening their nectar.

In 2009, Dr. Robert Lustig, a pediatric endocrinologist at the University of California, San Francisco delivered a ninety minute lecture entitled “Sugar: The Bitter Truth”. It was posted on YouTube as part of the university’s medical education series. Then a funny thing happened.

Advances in artificial intelligence have created new threats to the privacy of health data, a new UC Berkeley study shows. The study, led by professor Anil Aswani of the Industrial Engineering & Operations Research Department (IEOR) in the College of Engineering and his team, suggests current laws and regulations are nowhere near sufficient to keep an individual’s health status private in the face of AI development. The research was released today on JAMA Network Open.

These are dark days for supplements. Although they are a $30-plus billion market in the United States alone, vitamin A, vitamin C, vitamin E, selenium, beta-carotene, glucosamine, chondroitin, and fish oil have now flopped in study after study. If there was one supplement that seemed sure to survive the rigorous tests, it was vitamin D. People with low levels of vitamin D in their blood have significantly higher rates of virtually every disease and disorder you can think of: cancer, diabetes, obesity, osteoporosis, heart attack, stroke, depression, cognitive impairment, autoimmune conditions, and more.

Location of statues was based on nearby fresh water and other resources, says US study

We rarely portray Neanderthals, our close relatives, as telegenic. Museum exhibits give them wild tangles of hair, and Hollywood reduces them to grunting unsophisticates. Their skulls suggest broad faces, tiny chins and jutting brows.

New research suggests that the brain does not objectify people who are in revealing clothing if they’re not posed in a provocative way. The findings, which appear in Personality and Social Psychology Bulletin, indicates that objectification is mostly related to suggestive postures. “Sexualization is widely present in mass media with women (and to a lesser extent men) often depicted in sexualized ways. Objectification Theory (Fredrickson & Roberts, 1997) posits sexualization in the mass media is among the main vehicle of objectification of others...
