Oil Leak Could Be Stopped With a Nuke Screenshot-sm 799

An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

Stanford's "Autonomous" Helicopters Learn 90

An anonymous reader writes "Stanford computer scientists have developed an artificial intelligence system that enables robotic helicopters to teach themselves to fly difficult stunts by 'watching' other helicopters perform the same maneuvers. The result is an autonomous helicopter that can perform a complete airshow of complex tricks on its own. The stunts are 'by far the most difficult aerobatic maneuvers flown by any computer controlled helicopter,' said Andrew Ng, the professor directing the research of graduate students Pieter Abbeel, Adam Coates, Timothy Hunter and Morgan Quigley. The dazzling airshow is an important demonstration of 'apprenticeship learning,' in which robots learn by observing an expert, rather than by having software engineers peck away at their keyboards in an attempt to write instructions from scratch.'" The title of the linked article uses the term "autonomous," but that's somewhat misleading. The copters can't fly on their own, but rather can duplicate complex maneuvers learned from a human pilot.
