Privately funded spacecraft spreads its solar sails A privately funded space project to demonstrate an innovative solar sail passed with flying colors despite a series of near-fatal technical issues, program managers said on Wednesday. The 11-pound (5 kg) LightSail spacecraft, tucked inside a 4- by 4- by 12-inch (10- by 10- by 3-centimeter) box, hitched a ride into orbit aboard an Atlas 5 rocket carrying the U.S. Air Force's X-37B robot space plane on May 20. Funded by members of The Planetary Society, a California-based space advocacy organization, LightSail was intended to demonstrate how a tiny motor could unfurl four thin Mylar films into an area as big as a living room.

Together with a brewery, the scientists who have long studied bees and their honey, have launched their own mead drink - Honey Hunter's Elixir. Lund University researcher Tobias Olofsson said mead had a long track record in bringing positive effects on health. Read More »Thrusters on Soyuz Spacecraft at Space Station Fire Unexpectedly

"Every dual-task study that I'm aware of shows that, when people are doing two things at once, they get worse" at those tasks, study author Lori Altmann, an associate professor of speech, language and hearing sciences at the University of Florida, said in a statement. The participants completed 12 cognitive tasks while they were sitting in a quiet room, and then they did the tasks again as they were cycling.

For example, it's fine with the FDA for Americans to accompany their Thanksgiving turkeys with cranberry sauce containing an average of 15 percent mold filaments, based on a count made when samples of the sauce are viewed under a microscope. "Food defects are not things that cause people to get sick," said Benjamin Chapman, a food safety specialist and associate professor at North Carolina State University at Raleigh.

One year later, nearly 10 percent of the women in the brochure group reported that they had been raped, where a perpetrator used force, threats or incapacitating drugs to rape her. Women in the rape resistance group were also less likely to experience an attempted rape, where the perpetrator tried to rape the woman but was not successful.

Popular PPIs include Nexium, Prilosec and Prevacid. Read More »iPhone Will Track Your Sex Life: Is That Helpful? An update to Apple's Health app that is set for release this fall will let users track their sex lives, but experts say this tracking feature alone has little value for people's health. The sexual-activity tracking feature will be included as part of a new "reproductive health" section within Apple's Health Kit app, which will be available with the iOS9 update. A simple log of your sexual activity is not very useful by itself, except to perhaps make people feel good or bad about themselves, said Dr. Elizabeth Kavaler, a specialist in female urology at Lenox Hill Hospital in New York City.

When paired with a smartphone, 'Phree' frees users from the need to write on paper or the screen itself. Resembling traditional hand-held pens in size and shape, its developers say that Phree's appeal is in preserving the ancient act of writing or drawing while keeping up with technological advancements.

Scientists identify a gene that makes the call By Will Dunham WASHINGTON (Reuters) - Providing insight into the sometimes mysterious biology of reproduction, researchers in Japan have identified a gene that controls whether the reproductive precursor cells known as germ cells eventually become sperm or eggs. The scientists on Thursday described experiments involving a small fish called the medaka, or Japanese rice fish, that revealed the role of a gene called foxl3 in controlling the fate of germ cells. Germ cells are present in the bodies of vertebrates of both sexes, but the molecular mechanism that drives them to develop into either sperm, the male reproductive cell, or an egg, the female reproductive cell, has been elusive.

In the very beginning, it was to hold her hand," said Arnold, a paramedic firefighter from Missouri who suffered the first of three paralyzing strokes in 2009. These days Arnold can hold his wife's hand again thanks in part to a new device that could potentially change the rules on how well stroke victims recover. Arnold is using brain-machine interface technology developed by Eric Leuthardt, a neurosurgeon at Washington University in St. Louis.

The woman had her ovarian tissue frozen in her early teens, before she underwent a bone marrow transplant to treat her sickle cell anemia. Such transplants involve drugs that can destroy the ovaries.

The study included more than 63,000 patients ages 16 and older who suffered acute traumatic spinal cord injuries between 1993 and 2012.

If the FDA decides the drug is safe and effective, it could soon find its way into bedrooms across the United States. However, sexual desire is complicated, and some experts aren't sure that a pill is really the cure for an ailing female mojo.

In a new study, the researchers found that the rate of marijuana exposure in young children increased significantly from 2003 to 2013. As more states look to legalize marijuana, the risk for exposure to the drug can rise among children, the researchers said.

The 32-year-old woman with four children had recently been diagnosed with cervical cancer. In November 2012, her doctors requested the imaging scan to check to see if the cancer had spread (metastasized) to other parts of her body.

Overall, people in the study who were born in May were least likely to get a birth-month-related disease, whereas people born in October were most likely to get one. "This data could help scientists uncover new disease risk factors," Nicholas Tatonetti, the senior author of the study and an assistant professor of biomedical informatics at Columbia University, said in a statement.
