A once-a-day pill has been proven to lower the risk of getting HIV among needle-using drug addicts, just as it does among heterosexual couples and men who have sex with men.
Among 2,400 injecting drug users in Bangkok, those assigned to take a daily dose of an antiviral drug Viread, or tenofovir generically, had half the risk of getting HIV over a four-year period as those who took a placebo pill. Among those who took tenofovir faithfully, there were 74 percent fewer infections.
More women are getting into farming, according to a recent analysis from the U.S Department of Agriculture.
The agency crunched numbers from the Agriculture Census and found that the number of U.S. farms operated by women nearly tripled over the past three decades, from 5 percent in 1978 to 14 percent by 2007.
Finding the right treatment for depression can be a struggle. People find relief with the first treatment only 40 percent of the time. Trying different antidepressants or therapies can take months, which means months of suffering.
Scientists are trying to better the odds by searching for signals in the body or in behavior that could be signposts to the right treatment. Researchers at Emory University say that PET scans of the brain may help predict which people do better on SSRI antidepressants, and which would benefit most from cognitive behavioral therapy instead.

The Senate has defeated a Republican measure that would have blocked implementation of a "path to citizenship" for undocumented workers until after the U.S.-Mexico border has been deemed secure for a period of six months.
The amendment to the larger overhaul of U.S. immigration law was sponsored by Iowa Republican Sen. Chuck Grassley. It was defeated Thursday in a 57-43 vote.
What is it about dolphins? They have very, very big brains, and that makes we humans, whose brains are nothing to sniff at, nervous. We don't know what to make of them.
The latest example: On May 17 in India, the Ministry of Environment and Forests issued an order to all Indian states banning dolphin amusement parks. No leaping out of pools to catch balls, no jumping through hoops. Forcing dolphins to entertain humans, the ministry said, was morally unacceptable.

Turkey's Prime Minister Recep Tayyip Erdogan issued a strong warning to the protesters camped out at Taksim Square in Istanbul.
He said that within 24 hours, the situation at the square would be resolved. As The New York Times reports, the tough talk was tempered with an olive branch of sorts: Erdogan hinted that a referendum could decide whether a mall would be built in place of a park next to the square.
