DNA survives sub-orbital trip on the exterior of a rocket

DNA molecules smeared onto the exterior of a sub-orbital test rocket are capable of surviving a 13-minute trip into space and a scorching re-entry, European researchers say. The scientists' surprising finding, which was published Wednesday in the journal PLOS One, suggests that genetic material is hardier than previously thought and may have the potential to stow away on robotic landers bound for other worlds, or within meteors, the report said. "It is conceivable that life exists independently from our planet even under the very hostile conditions prevailing on our neighbors like Mars," wrote senior study author Dr. Oliver Ullrich, a molecular biologist at the...
