First of a four-part series featuring women in grid computing

Feature: Through the gateway into the realm. . . to get results

Deep, wide, open. This three-pronged conceptualization underlies the TeraGrid, a National Science Foundation cyberinfrastructure initiative. “Deep” refers to digital muscle—more than a petaflop of aggregated computing power. “Open” connotes extensibility, the ability to include new resource providers and university partnerships to broaden the resource base. “Wide” means that the TeraGrid wants its resources to be useful to as many researchers as possible.

To that end, TeraGrid has created “Science Gateways”—diverse entry points for the uninitiated to pass into the realm of computational science. Implemented in 2005, the Science Gateways program, led by Nancy Wilkins-Diehr of the San Diego Supercomputer Center, has grown rapidly and now comprises 35 Gateways—each of them tailored by and for a specific research community.

 Be still, my heart

A doctor puts a pair of electrical paddles against a patient’s chest, yells “clear,” gives an electric shock — and whew, the heart starts beating again normally. The whole process, known as “defibrillation,” is relatively common in both television shows and real-life emergency rooms.

But what is really happening, and why does it work?

/The Register: Girls still not swarming into sci-tech, dammit

US researchers have issued a comprehensive roundup of research covering that hotly-debated topic: Why aren't there more girls in the sci/tech/engineering/maths-based world?

According to the paper, men in general aren't all that much better than women at math. But at the high end of geek type reasoning, there are a lot more chaps.

The Register sums it up and links to the full report.
