Prescription Testosterone Gets New Warning

The labels on prescription testosterone will now carry a new warning about the serious health risks that have been linked with abuse of these products. The Food and Drug Administration (FDA) announced the new labels today (Oct. 25), saying that some people abuse testosterone drugs. For example, the agency said, athletes and body builders have been known to take doses that are higher than those prescribed, and to use testosterone together with other anabolic steroids.

Astronauts' Back Pain Has Surprising Cause

Astronauts may have no trouble moving heavy objects in the weightlessness of space, but that doesn't mean that the experience isn't hard on their backs. Astronauts on long-duration spaceflights routinely report back pain, both during and after the flight. In a new study, researchers used magnetic resonance imaging (MRI) scans to observe the spines of six NASA astronauts before they landed, at the time of landing and about two months after they had spent upward of seven months on the International Space Station.

Heart-Healthy Cities: These Spots Have the Least Heart Attacks

Communities in the U.S. range widely in the percentage of residents who've had heart attacks, a new report shows. Less than 2 percent of the residents of Boulder, Colorado, and Ann Arbor, Michigan, reported having had heart attacks, according to new findings from a Gallup-Healthways survey of people living in 190 U.S. metro areas, conducted in 2014 and 2015. The community with the highest rate of heart attacks was Charleston, West Virginia, according to the survey.

New Plastic-Based Textile Helps Cool You Off

A new type of fabric could keep people cool in hot climates and reduce the need for expensive and energy-consuming air conditioning, a new study finds. Just as sweating is one way the body cools off, the new clothing could help people reduce body heat. Heating and cooling spaces contribute to 12.3 percent of total energy consumption in the U.S., according to the researchers.

Recovered WWI German U-Boat Revives 'Sea Monster' Tales

The wreck of a World War I German submarine has been discovered off the coast of Scotland by marine engineers surveying the route of an undersea power cable. Researchers said they think the wreck is one of two German U-boats sunk by British patrol ships in the Irish Sea in 1918 — including one that was supposedly attacked by a sea monster, according to an internet legend. Marine archeologist and historian Innes McCartney, from Bournemouth University in the United Kingdom, said the submarine wreck was in reasonably good shape, considering it has spent almost 100 years on the seafloor at a depth of 340 feet (about 100 meters).

Picture This: Startup Satellite Fleet Will Image Planet Daily

The company, known as Planet, is aiming to make global change visible, accessible, and actionable for everyone, Will Marshall, the startup's co-founder and CEO, said during an address to the United Nations Sustainable Development Summit on Sept. 27, 2015. The company has deployed large fleets of small, inexpensive satellites designed solely to capture images of the planet. "We miniaturized these little satellites, and we put them up [in space] in large fleets in order to image the planet, with their little cameras going around the Earth," Marshall said during a talk at the Bloomberg Technology Conference in June.

No, 'Honeycomb' Clouds Don't Explain Bermuda Triangle Mystery

A satellite image showing peculiar hexagonal clouds over the ocean area known as the Bermuda Triangle is prompting speculation about whether they may represent a recurring phenomenon responsible for decades of unexplained disappearances in the region. The photo appeared in the Science Channel's "What on Earth"? According to the Science Channel, similar cloud formations in the North Sea near the U.K. have been associated with so-called "air bombs" — powerful downdrafts of air that could overpower and destroy ships and airplanes.

Tweet #SnailLove to Help Lonely Mollusk Find a Mate

Most snails have right-spiraling, or dextral, shells, said Angus Davison, an associate professor and reader in evolutionary genetics at the University of Nottingham's School of Life Sciences in the United Kingdom. Davison, who has studied the snail, said that unfortunately for Jeremy, his sinistral shell means that his genitals are on the opposite side of his body compared with most garden snails, making it very difficult for him to mate with dextral snails.

Mysterious 'Dark Energy' May Not Exist, Study Claims

The universe may not be expanding at an accelerating rate after all, meaning that mysterious "dark energy" might not actually exist, according to a new study. In 2011, three cosmologists from two research teams won the Nobel Prize in physics for independently showing that distant Type Ia supernovas, which are a kind of exploding star, are moving away from Earth faster than nearby ones are. This hypothetical dispersive force came to be known as dark energy, because astronomers didn't really know what it was (and still don't, as a matter of fact).
