Findings from the study, which has yet to be published or reviewed in detail by other scientists, were presented at a meeting of the American Society of Human Genetics in Baltimore.

Bike riders who wear helmets are 58 percent less likely to get a severe traumatic brain injury (TBI) after an accident compared with riders who aren't wearing helmets, according to the findings presented today (Oct. 8) at the 2015 Clinical Congress of the American College of Surgeons in Chicago. Researchers at the University of Arizona Medical Center looked at the records in a national injury database of 6,267 people who had an intracranial hemorrhage (a brain bleed)following bicycle-related accidents in 2012.

The findings suggest that although enough people are vaccinated to prevent measles from spreading widely in the United States, there could still be large outbreaks of the disease, due to clusters of unvaccinated children, the researchers said. "We can't get complacent" about vaccinating kids against the measles, said study researcher Robert Bednarczyk, an assistant professor of global health at Emory University in Atlanta.

"Sometimes stool color is very important, and sometimes we can get worried inappropriately about the color of stool," Dr. Ian Lustbader, a clinical associate professor of medicine and a gastroenterologist at New York University's Langone Medical Center, told Live Science. Most likely, it's the food coloring in the bun, Lustbader said.

Until now, genome sequencing efforts on ancient people have focused on remains from cooler, drier climes that tend to better preserve DNA. The cave, sitting 6,440 feet (1,963 meters) above sea level in southwestern Ethiopia's Gamo highlands, was discovered in 2011, University of Cambridge geneticist Andrea Manica said.

A new study using a sediment core extracted from the Gulf of Aden found the East African region covering Somalia, Djibouti and Ethiopia has dried at an unusually fast rate over the past century. Lead author Jessica Tierney, an associate professor at the University of Arizona, told the Thomson Reuters Foundation the research team was confident the drying was linked to rising emissions of climate-changing greenhouse gases, and was expected to continue as the region heats up further.

Jaundice is a yellowing of the skin, and is often a sign of liver problems. "I had only lost a couple of pounds, but then started having horrible pains in my joints, and felt very dizzy and sick," the girl said, writing in the "patient perspective" section of the case report.

In 2013, over half of the hospitals in the United States were meeting at least five of 10 common recommendations for hospitals to support breast-feeding, up from 29 percent of hospitals that met that many recommendations in 2007. Breast-feeding is the most effective way for babies to get the best nutrition, and hospitals play a major role in supporting moms who want to breast-feed, Dr. Tom Frieden, director of the CDC, said at a news conference today (Oct. 6).

In the study, researchers looked at more than 8,800 people who'd had weight-loss surgery, monitoring them for three years before their surgery and three years after their operation. There were 62 reports of self-harm in the three years prior to people's surgeries, compared with 96 reports of self-harm in the three-year period after these people had weight-loss surgery — an increase of 54 percent.

The ads contained warnings about the harms of tanning beds, and directed people who clicked on them to information from the Centers for Disease Control and Prevention.

Irish-born William Campbell and Japan's Satoshi Omura won half of the prize for discovering avermectin, a derivative of which has been used to treat hundreds of millions of people with river blindness and lymphatic filariasis, or elephantiasis. China's Tu Youyou was awarded the other half of the prize for discovering artemisinin, a drug that has slashed malaria deaths and has become the mainstay of fighting the mosquito-borne disease.

Neutrinos are the second most bountiful particles after photons, which carry light, with trillions of them streaming through our bodies every second, but their true nature has been poorly understood. Takaaki Kajita and Arthur McDonald's breakthrough was the discovery of a phenomenon called neutrino oscillation that has upended scientific thinking and promises to change understanding about the history and future fate of the cosmos.

The rocket, built and flown by United Launch Alliance, a partnership of Lockheed-Martin and Boeing, lifted off from a seaside launch pad at Vandenberg Air Force Base at 8:49 a.m. EST, a live ULA webcast showed. The rocket's primary cargo, owned by the National Reconnaissance Office (NRO), was not disclosed.

In experiments, researchers looked at the effects of two vasodilators — which are medicines that cause blood vessels to widen, increasing blood flow — on certain receptors in rats' brain cells. They found that when they administered one of these vasodilators, nicknamed PACAP, directly into the rats' brains, a cluster of neurons in the center of the head called the trigeminovascular system started firing more than normal, mimicking the symptoms of a migraine in the animals.

"The theoretical model which best fits our data indicates that the core is losing heat more slowly than at any point in the last 4.5 billion years and that this flow of energy should keep the Earth's magnetic field going for another billion years or more," Biggin said in a statement. For much of those early years, Earth was a blob of molten rock, but over time, the surface cooled and formed a crust that floated on the Earth's liquid core.
