Tom Farber, a calculus teacher at Rancho Bernardo high school in San Diego, has come up with a unique way of covering district cuts to his supplies budget. He sells ads on his tests. "Tough times call for tough actions," Tom says. The price of an ad on a Mr. Farber Calc test is as follows: $10 for a quiz, $20 for a chapter test, and $30 for a semester final. Most of the ads are messages from parents but about a third of them come from local businesses. Principal Paul Robinson says reaction has been "mixed," but adds, "It's not like, 'This test is brought to you by McDonald's or Nike.'" I see his point. Being a local business whore is much better than being a multinational conglomerate whore.

An anonymous reader writes "Saudi Arabia is building a supercomputer that could rank among the 10 most powerful systems in the world. And the country isn't stopping there. It has plans to turn this marquee system for the Middle East into a petascale system in two years, and, beyond that, an exascale system."

Stefan vd Linden writes, "An international team of scientists has discovered a substance to heal bleeding wounds within seconds. They're using a solution of protein molecules that self-organizes into a biodegradable gel. Until now they've only tested it on animals, but the tests were highly successful. From the article: 'Some surgeons are already excited about the material. "I see great potential in the eye field, the gastro-intestinal field, and in neurosurgery," says Dimitri Azar, head of ophthalmology at the University of Illinois at Chicago, US. "In the eye, even a drop of blood will blur your vision for a long time," Azar adds. "A material that would stop the bleeding could lead to a paradigm shift in how we practice surgery in the eye."'"
