Robotic arm probes chemistry of 3-D objects by mass spectrometry
Atlanta GA (SPX) Mar 26, 2014 - When life on Earth was first getting started, simple molecules bonded together into the precursors of modern genetic material. A catalyst would have been needed, but enzymes had not yet evolved. One theory is that the catalytic minerals on a meteorite's surface could have jump-started life's first chemical reactions. But scientists need a way to directly analyze these rough, irregularly sh ... more
