Chinese Want To Capture an Asteroid 481

geekmansworld writes "The Chinese want to capture an asteroid into earth's orbit and mine it. From the article: 'At first glance, nudging an asteroid closer to Earth seems like one of those "what could possible go wrong" scenarios that we generally try and avoid, and for good reason: large asteroid impacts are bad times. The Chinese, though, seem fairly optimistic that they could tweak the orbit of a near-Earth asteroid by just enough (a change in velocity of only about 1,300 feet-per-second or so) to get it to temporarily enter Earth orbit at about twice the distance as the Moon.'"

Homemade 'Mars In a Bottle' Tortures Bacteria 154

astroengine writes "The only time we've ever directly looked for life on Mars was during the 1970s, when NASA's Viking landers attempted to make direct measurements of Martian microbes metabolizing. Even today, the results of these groundbreaking experiments are hotly debated. Although the Viking experiments were often considered premature, a team of scientists hope to refine the next life-searching experiment to be sent to the Red Planet by building a Mars habitat on Earth. Imagine a Mars environment 'goldfish bowl' complete with UV radiation, dust, chilly temperatures, and an extremely low atmospheric pressure. So what have they done with this micro-Mars environment? They've been torturing various terrestrial microbes to see how they enjoy stints on the Martian surface. Their results have shown that even Earth microorganisms have a trick or two up their sleeves to survive in this alien environment."

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."
