How to Choose a Sunscreen That Protects You

Fewer than half of the 114 study participants could correctly identify how well a sunscreen protected against health problems such as sunburn, photoaging (premature aging of the skin caused by exposure to sunlight) and skin cancer just by looking at the product's label, according to the researchers at Northwestern University Feinberg School of Medicine in Chicago who conducted the study. And it's not just the small sampling of people who participated in the study who have trouble deciphering sunscreen labels, said Dr. Jennifer Stein, an assistant professor of dermatology at New York University's Langone Medical Center who was not involved in the study. "At least half of the patients I see — especially this time of year — ask me questions about sunscreen," Stein told Live Science.

Which State Has the Highest Death Rate from Injuries?

West Virginia is the state with the highest rate of death from injuries, such as those sustained in car crashes, falls, fires and drug overdoses, while New York has the lowest rate, according to a new report. Researchers analyzed information on death rates from injuries — both intentional and unintentional — in all 50 states and Washington, D.C., between 2011 and 2013. In West Virginia, there were about 98 deaths from injuries per 100,000 people.

Curbing Accidental Pregnancies: Docs Should Mention IUDs, Implants

Young women who talk with a doctor about long-term contraception may have fewer unintended pregnancies, a new study suggests. Research has shown that intrauterine devices (IUDs) and progestin implants — which can prevent pregnancy for years after they are inserted — are more effective at preventing pregnancy than other, more widely used methods such as condoms or birth control pills. Considering that about 50 percent of pregnancies in the U.S. are unintended, the researchers wanted to see whether training health providers on how to educate young women about IUDs and implants would affect the number of unintended pregnancies.

Online human breast milk craze has serious health risks: experts

Writing in the Journal of the Royal Society of Medicine, specialists said there was little evidence to support claims that the milk - traded via websites in a lucrative market for adult buyers - is some kind of super food that can boost health and fitness and ward off disease. On the contrary, the experts warned, raw and unpasteurized human breast milk bought online can expose consumers to many serious infectious diseases, including hepatitis, HIV and syphilis. It is also potentially very hazardous if used to replace a healthy balanced diet, Sarah Steele, a specialist at the global health and policy unit at Queen Mary University of London, wrote in the journal.

Sleep through my piece, please, composer Max Richter says

By Michael Roddy LONDON (Reuters) - People since time immemorial have been dozing off in concert halls. Now British composer Max Richter has written an eight-hour-long piece called "SLEEP" which he says is designed to make people nod off during the performance -- with beds provided. "It's an eight-hour lullaby," Richter, one of Britain's leading contemporary composers, said in a statement released on Wednesday, which adds that the piece, which features electronic sounds and a lulling cello line, is literally "intended to send the listener to sleep".

The Science of Race: Why Rachel Dolezal Can't Choose to Be Black

The media and the public have been buzzing about the bizarre case of Rachel Dolezal, the former head of the Spokane, Washington, chapter of the National Association for the Advancement of Colored People, who says she identifies as black despite being born white. In a "Today" show interview that aired yesterday (June 16), Dolezal hinted at a mismatch between her appearance and how she saw herself from a young age. "I was drawing self-portraits with the brown crayon instead of the peach crayon, and black, curly hair," Dolezal said in the interview.

Mind Meld: Social Wasps Share Brainpower

Wasps that live in large, social colonies may "share" brainpower, a new study finds. Perhaps social wasps make up for these smaller "higher thinking" areas by working together and sharing brainpower, the researchers said. "The idea is basically that, by communicating and responding to colony mates, a social insect is under less pressure to assess and respond to its environment on its own," said lead researcher Sean O'Donnell, a professor of biodiversity, earth and environmental science at Drexel University in Philadelphia.

Search for King Henry's Tomb Centers on English Playground

In the wake of an archaeological dig that found the bones of Richard III beneath a parking lot in Leicester, England, British historians and archaeologists are turning to a church and school yard in the town of Reading in search of the remains of Henry I, who ruled England from 1100 to 1135. The modern buildings are on the site of the old Reading Abbey, which was shut down — its abbot was hanged for treason — in 1539. "We have a very good idea, within a few feet or yards, of where Henry was buried," said John Mullaney, a local historian and author of "Reading's Abbey Quarter: An Illustrated History" (Scallop Shell Press, 2014).

Finding Amelia Earhart: New Expedition Could Solve Decades-Long Mystery

The search for Amelia Earhart is on (again). An organized search party called "The Earhart Project," led by The International Group for Historic Aircraft Recovery, also known as TIGHAR (pronounced "tiger"), is in its second week of searching for clues surrounding the mysterious disappearance of legendary aviator Amelia Earhart. The Earhart Project is testing the hypothesis that Earhart and her navigator, Fred Noonan, made an emergency landing, and eventually died, on Gardner Island, also called Nikumaroro, an uninhabited island in the Republic of Kiribati, in the western Pacific Ocean.

Southpaws Down Under: Most Kangaroos Are Lefties

Those boxing kangaroos have a secret: They're southpaws. New research finds that the eastern gray kangaroo (Macropus giganteus) and the red kangaroo (Macropus rufus) prefer to use their left forelimbs when feeding and grooming. The discovery of handedness in kangaroos is surprising, scientists said.

Ancient 'Kennewick Man' skeleton was Native American: study

The much-anticipated results of a study of DNA taken from the hand bone of the so-called Kennewick Man, a 8,500-year-old skeleton discovered in Washington state in 1996, suggest the man was most closely related to Native American populations, a team of international researchers said on Thursday. The DNA findings, published online in the journal Nature, contradict a 2014 study based on anatomical data that suggested the skeleton was most closely related to Polynesian or indigenous Japanese populations. The Kennewick Man, named for the site of his discovery near the banks of the Columbia River in Kennewick, Washington, has been at the center of a bitter legal dispute between scientists, who want to study the remains, and a coalition of Native American tribes, which is arguing for their reburial.

That's right, kangaroos are left-handed

By Will Dunham WASHINGTON (Reuters) - Research on wild kangaroos in Australia is challenging the notion that having a strong hand preference is a trait that developed primarily in people and other primates. Scientists said on Thursday that these Australian marsupials displayed a natural preference for using their left hand for feeding, self-grooming and other activities. "We found a pronounced degree of 'handedness,' comparable to that in our species," said biologist Yegor Malashichev of Saint Petersburg State University in Russia.

Trans Fat May Impair Memory

Even as a new rule will force food companies to stop adding trans fat to food, research continues to show the negative effects of trans fat on health. In the study, researchers found that men ages 45 and younger who consumed high amounts of trans fat performed worse on a memory test than men whose consumption of trans fat was lower. "Trans fats were most strongly linked to worse memory in men during their high-productivity years," study author Dr. Beatrice A. Golomb, a professor of medicine at the University of California, San Diego School of Medicine, said in a statement.

Online Breast Milk Carries Health Hazards, Report Warns

Human breast milk is available on the Internet, and people are buying not only raw milk but also products such as breast-milk-flavored ice cream and lollipops, researchers say. Breast milk websites are plastered with health claims stating that breast milk is a natural superfood that can help people build muscles and immunity, according to the authors of the article, led by Sarah Steele, a lecturer at the Global Health and Policy Unit of Queen Mary University of London. Breast milk is beneficial for infants, and scientists are studying the health effects of its molecular components, but it shouldn't be part of an adult's diet, the researchers said.

Unhealthy Data? US Dietary Guidelines Criticized

At issue is the fact that U.S. dietary guidelines are based heavily on data from self-reported questionnaires, on which ordinary people reported the types of food and drinks they consume day-to-day. But ordinary people can forget, guess or even lie their way through the questionnaires. For the past five decades, such questionnaires have been at the heart of a program called the National Health and Nutrition Examination Survey (NHANES), which is run by researchers at the Centers for Disease Control and Prevention.
