In a milestone announcement, today the FDA approved the use of Truvada, the first drug to be used for HIV prevention in the 30-plus year battle against the virus. To be used as part of safe sex practices and continued testing, the drug, which was first approved in 2004, has already shown promise in preventing infection, with some figures placing protection rates as high as 90 percent.

A new bionic eye implant could allow blind people to recognize faces, watch TV and even read. Nano Retina's Bio-Retina is one of two recent attempts to help patients with age-related macular degeneration, which affects 1.5 million people in the U.S.
In an effort to outfox antibiotic resistance, a team of researchers based out of U.C. Berkeley--and including none other than Nobel laureate Steven Chu--want to build a wrecking ball that tears down bacterial cities. It’s not quite there yet, but in a paper released today the research group announced that via a new imaging technique it has for the first time revealed the structure of these biofilms -- and where they are vulnerable to attack.
Because we don't spend a large chunk of time up there, we haven't done too much research on the long-term health effects of living on the moon. But a paper titled "Toxicity of Lunar Dust," covering several aspects of the effects of moon dust on the human body, offers some insight: the moon is basically trying to kill you.
Using a smartphone and ultra wide band (UWB) transmission technology, Japan’s National Institute of Information and Communications Technology (NICT) and Fujitsu have teamed to create a realtime positioning system for the blind that works indoors where GPS can’t reach. Using base stations to triangulate a user’s position, the system is accurate to within 30 centimeters, or roughly one foot.
Texting while driving is enough of a problem that it's been pinned as more dangerous than drunk driving, so it was only a matter of time before we started to see technology better able to shut it down. Now on that list: researchers have found a way to detect when a phone is being used in a moving car, then jam it.
Getting to space is a tough enough prospect, and even once you make it out of our atmosphere, there are still physical issues. Chief among them: a long flight can cause a loss of bone and muscle mass. To find ways to combat that process, researchers study C. elegans, worms that have a surprising amount in common with humans. But a recent study noticed a strange side effect for space-bound worms: they lived longer.
Just in time for that annual fourth of July cookout in which you drag all that filthy white lawn furniture from its molding, mildewing stack out behind the shed: a team from Germany’s Fraunhofer Institute has created a titanium dioxide-doped polymer coating that kills germs and bacteria when exposed to sunlight. Self-cleaning lawn furniture surely can’t be far behind.
It's official: the Supreme Court has upheld the Affordable Care Act, which, however you feel about it, means 32 million Americans will likely gain health care coverage. A part of the legislation dictates that all those people, by law, need somewhere to enroll, compare coverage, and purchase insurance. The design consultancy Ideo has spent more than a year putting together an open-source template to keep the potential paperwork from crushing everyone before they even have health insurance to cover the damage.
Nicotine addiction is a hard habit to break. But what if you could never get hooked in the first place? Researchers at Weill Cornell Medical College in New York report in the journal Science Translational Medicine that they have developed a potential vaccine for nicotine addiction. In mice, the vaccine inhibits the effects of nicotine before they reach the heart or brain, making it seem as though the nicotine never entered the bloodstream.
