Hugh Pickens writes "Blacksmith Institute has published their list of the most polluted sites in the world compiled by comparing the toxicity of the contamination, the likelihood of it getting into humans and the number of people affected. For example, ninety-nine percent of the children living in and around the poly-metallic smelter at La Oroya in Peru, owned by the Missouri-based Doe Run Corporation, have blood lead levels that exceed acceptable limits. Scientific American says that despite the massive pollution, it would be relatively cheap and easy to clean up the most dangerous hazards. For $15,000, the radioactive contaminated soil from the Mayak plutonium facility on the shore of the Techa River in the Russian town of Muslyomova could be dug up, saving an estimated 350 lives. 'For about $200, the cost of a refrigerator, we are able to save someone's life,' says Richard Fuller, founder of Blacksmith."

serutan writes "Using lasers to drive spaceships has been a subject of interest for many years, but making a photonic engine powerful enough for practical use has been elusive. Dr. Young Bae, a California physicist, has built a demonstration photonic laser thruster that produces enough thrust to micro-maneuver a satellite. This would be useful in high-precision formation flying, such as using a fleet of satellites to form a space telescope with a large virtual aperture. Scaled up, a similar engine could speed a spacecraft to Mars in less than a week."

jpkunst sends us to Computerworld for a look at Michael Stonebraker's opinion that RDBMSs "should be considered legacy technology." Computerworld adds some background and analysis to Stonebraker's comments, which appear in a new blog, The Database Column. Stonebraker co-created the Ingres and Postgres technology while a researcher at UC Berkeley in the early 1970s. He predicts that "column stores will take over the [data] warehouse market over time, completely displacing row stores."

eldavojohn writes "Further evidence for the asteroid mass extinction theory has been discovered as a break in the main asteroid belt of our solar system. From the article, "A joint U.S.-Czech team from Southwest Research Institute (SwRI) and Charles University in Prague suggests that the parent object of asteroid (298) Baptistina disrupted when it was hit by another large asteroid, creating numerous large fragments that would later create the Chicxulub crater on the Yucatan Peninsula as well as the prominent Tycho crater found on the Moon.""

jd writes "Steve Fossett, the first person to fly a plane around the world without refueling, the first person to fly around the world in a balloon, and possibly the record-holder for the highest-altitude glider flight, is missing in Nevada. He is reported to have taken off in a light aircraft last night and has not been seen since. As he had filed no flight plan, would-be rescuers have no idea where to even begin looking. The plane took off from a private airstrip on a ranch at the south end of Smith Valley in western Nevada."
