Life Stinks Says New AnalysisGreenbelt MD (SPX) Mar 28, 2011 The origin of life may have been smelly, according to a recent, NASA-funded analysis of residue from a variant of classic experiments performed by Dr. Stanley Miller in the 1950s. "One of the primary differences between this experiment and others Miller performed is the use of hydrogen sulfide (H2S) gas to help simulate the primordial atmosphere," said Eric Parker of the Georgia Institute of Technology, Atlanta, Ga. Hydrogen sulfide gas is commonly known as the awful smell released by rotten eggs. ... read more |
