Until the naked mole rats yield their secrets, humanity will still have to worry about treating and controlling cancer. And to that end, one company may have figured out a novel way to prevent the spread of a highly dangerous form of brain cancer, through the use of pulsing electric fields.

While some companies hope an iTunes-like approach to distributing scientific papers on the cheap will get journal articles into the hands of people who need them, a new study shows that many medical students are already taking the Napster approach. A new paper studying the downloading habits of medical students found 125,000 users of peer-to-peer filesharing services who obtained some 5,000 scientific papers for free, circumventing the usual $30 fee.

A new website lets you figure out how you might die, by sorting death data by cause of death, sex, and age. For American males ages 20-29, the most common cause of death is accidents (40.2 percent of deaths), followed by homicide (17.5 percent), and suicide (11.7 percent). Urinary tract infections? 0.3 percent.

In a development sure to drive Stephen Colbert apoplectic, the Japanese national laboratory RIKEN has announced the development of robotic nurses that look like bears. Called Robot for Interactive Body Assistance (RIBA), the robot was designed to help a country facing the dual problem of a shortage of nurses and a rapidly aging population.

Skin does more than look good (or, in my case, get covered in pimples and easily burned by the sun). It also protects the body from infection, dehydration, and a generally hostile world. As a result, victims of burns and skin diseases face serious problems beyond the obvious issues of pain and aesthetics.

For years, doctors have tried use synthetic skin for grafts and repairs, but the process to create that synthetic skin has always been expensive and time-consuming.

Now, a team from Germany's Fraunhofer-Gesellschaft science institute have created a way to mass-produce artificial skin, complete with blood vessels, that can be used for grafts, plastic surgery, or even cosmetics testing.

Researchers at the University of Massachusetts, Amherst, are developing child-sized, wheeled robots that could soon start helping elderly people in their homes. Computer scientist Rod Grupen, who led the team that developed uBot-5, notes that robots are finally safe and inexpensive enough to perform a real function in homes. The robot has an LCD screen, a webcam, and a wireless connection to the Internet. It speeds around and balances on two Segway-like wheels. If it does happen to fall, though, uBot-5 uses its long arms to do a push-up, and return itself to an upright position.
