NASA 'Tricorder' To Hunt For Life On Alien Planets

Just like the handheld gadget from the old 'Star Trek' series, a newly invented "TRICORDER' called NUGGET is designed to search for evidence of life on other planets by using three technologies: a neutron generator, a neutron lens, and a gamma-ray detector. The principal investigator for the project even looks a little like Mr. Spock. Fascinating.
