In a new paper published on Sunday and delivered at a meeting of the American Astronomical Society a scientist is stating his theory that two NASA space probes (Vikings) may have found alien microbes on Mars 30 years ago but inadvertently killed them. The theory presented is that Voyager was looking for life forms specific to Earth-life, where salt water is the internal liquid of living cells, rather than hydrogen peroxide, a liquid which could more realistically survive the cold and dry climate of Mars. As the Viking probes performed their experiments on the Mars surface any hydrogen peroxide-based life would have been killed by experiments consisting of water poured onto the planet surface and another which heated the soil to see if something would occur, essentially baking and Martian microbes.

Oops. An incident which occurred at Pantex, the only factory in the country for assembling and disassembling nuclear weapons, could have caused a 1.2 megaton nuclear bomb to detonate, likely taking most of Texas with it. Thanks to several anonymous letters, it has come to light that during the disassembly of the bomb, an extremely unsafe amount of pressure was applied to the warhead, which was reportedly enough to detonate the bomb. The Energy Department has recently fined the plants operators $110,000 for the incident, which was never reported until the plant was actually forced to divulge its investigation on the mishap. It is charged that overworked technicians (who work up to 70 hour weeks) were partly to blame.The device was reported to be a W56 warhead, with a yield of 1,200 kilotons, which is 100 times the power of the bomb dropped on Hiroshima during World War II.
