When surgeons need to deliver a payload directly to a patient's brain, it usually involves a rather invasive procedure that opens the skull and leaves the delicate grey matter inside inflamed. But researchers at the University of Minnesota have discovered that patients with brain maladies can simply snort stem cells through the nose and directly to the brain, offering an effective and fast alternative to complicated neuro-surgical procedures.

A team of Austrian scientists have recently taken their colleagues to task for limiting their extraterrestrial search to carbon-based, water-reliant life. In response, they've begun experiments to see whether, water aside, any other solvents have the necessary properties to support extraterrestrial life.
Recently we spoke to Dr. Seth Shostak, senior astronomer at SETI, on just why it is we think extraterrestrial life requires water and carbon. Is it simple scientific fact? Not quite. A lack of humility? Not that either. The answer, as is often the case in the annals of science, is one of practicality.
A text-messaging microchip planted on the patient's body significantly boosts compliance with doctor's prescriptions, according to pharmaceutical giant Novartis. That's good news for patient health and reining in healthcare costs, but a potentially worrisome development for privacy advocates.
Patients taking a drug for lowering blood pressure also received two additional gifts: tiny microchips within each pill and a shoulder-attached sensor patch.
That's what it looks like, doesn't it? In reality this is Sydney, Australia, Earth, shrouded in a severe dust storm that has covered much of the country's eastern coast for the last few days. And while breathing is hard and transportation has ground to a standstill, the photos are spectacular.
Conventional wind turbines have an Achilles heel in the form of their clunky and expensive gearboxes. But that could change with GE's recent purchase of a company that has developed gearless turbine technology based on magnets.
Gearboxes act as the middleman to convert the slow rotations of wind turbine blades into the faster rotations needed for generators to create electricity. The downside of such gears comes from their high-maintenance requirements due to constant stress from wind turbulence.
Patients with alcohol in their blood are less likely to die from head injuries, according to a new study in Archives of Surgery, a JAMA/Archives journal.
The researchers found that the patients who tested positive for alcohol were less likely to die than patients who had no alcohol in their bloodstream. They were also generally younger and had less severe injuries. But patients who had drunk alcohol did suffer more medical complications during their stay in the hospital.

The numbers tell the story: Of the 648 people killed by lightning in the U.S. from 1995 to 2008, 82 percent were male. And as much as we were hoping to uncover a biological cause—extra iron in the male cranium, perhaps, or the conductive properties of testosterone—it turns out men are... just kind of stupid. “Men take more risks in lightning storms,” says John Jensenius, a lightning safety expert with the National Weather Service.
Japan certainly hasn't let the recession damp its enthusiasm for all things robot, even if much of the robotic workforce still suffers from unemployment idleness.
The robot tiles emerged as the brainchild of Hiroo Iwata, a virtual reality researcher at the University of Tsukuba in Japan. A touch-sensitive conductive fabric covers each robot and gauges the pressure applied by a walking person's foot, which goes toward predicting the next step.
No less than the open freedom of the Internet is at stake in the war over net neutrality. Now FCC chairman Julius Genachowski has waded into the fray with two new proposals and a clear message: an open and nondiscriminatory Internet is a must for the future.
That stance emerged today in Genachowski's address at the Brookings Institute in Washington. He laid out problems such as the limited competition among ISPs, the economic incentives for ISPs to sell bundled phone and TV service with Internet, and the burden of growing Internet traffic that puts pressure back on ISPs.
A team of former rivals has officially won the competition to improve Netflix movie recommendations. The collaborative known as BellKor's Pragmatic Chaos took home a $1-million prize today for their winning submission from July 26, which beat out yet another rival team's matching submission by just 20 minutes.
