Scientists have discovered a new way to analyze the moving parts of large proteins -- a breakthrough that will make it easier for structural biologists to classify and scrutinize the active sites of proteins implicated in cancer and other diseases.
According to a recent study, pharmaceuticals are being found in septic tanks and, consequentially, ground water due to incomplete human metabolism and excretion into the waste stream or by disposal of unused medications in the toilet or down the sink.
Tungsten began increasing in trees in Fallon, Nevada several years before the town's rise in childhood leukemia cases, according to a recent study. This is the first study that has examined changes in levels of heavy metals in Fallon over time.
Sleep remains one of the big mysteries in biology. All animals sleep, and people who are deprived of sleep suffer physically, emotionally and intellectually. But nobody knows how sleep restores the brain.
Researchers have found bonobos and chimpanzees use manual gestures of their hands, feet and limbs more flexibly than they do facial expressions and vocalizations, further supporting the evolution of human language began with gestures as the gestural origin hypothesis of language suggests.
Teens who have chronic daily headache, especially those with migraine headaches, are at greater risk for suicide than teens who don't have migraines, according to a new study. Teens with migraine are also more likely to have other psychiatric disorders such as depression and panic disorder.
It may not be quite as exciting as the X-Prize competitions, but NASA's latest Centennial Challenge looks like it could prove to be fairly consequential in its own right, tasking competitors to build a better astronaut glove, NewScientist reports. Set to go down on May 2nd and 3rd, the challenge will pit six teams against each other, with $250,000 in prize money up for grabs, not to mention the possibility of the winning design actually being put into use in space. From the looks of it, the entrants themselves will also face more than a few challenges, with one test requiring a team member wearing their glove to squeeze a ball inside a pressurized box for 30 minutes -- if blood starts dripping out, they're disqualified. As with its other challenges, however, NASA isn't expecting to find a winner in its first year, so those that missed out this time 'round may still get a shot at making the cut for next year's competition

The Great Pretender writes: The BBC reports that scientists are developing a pill which could boost women's libido and reduce their appetite. The hormone-releasing pill has so far only been given to female monkeys and shrews who displayed more mating behavior and ate less. The team from the Medical Research Council's Human Reproduction Unit in Edinburgh believe a human version could be available within a decade. http://news.bbc.co.uk/2/hi/health/6606927.stm.

A portrait of a breast cancer survivor was deemed indecent, banned and removed from an art show. The piece is a simple figure study of a woman with a scar. Why was this piece considered morally offensive? Because the model is older? Disfigured by disease? Or are there implied subtexts to this piece simply because the artist is a dyke?"
