Originally considered a dud, an old volcano-in-a-bottle experiment designed to mimic conditions that may have brewed the components of life might have been right on target.
After reanalyzing the results of unpublished research conducted by Stanley Miller in 1953, chemists realized that his experiment had actually produced a wealth of amino acids — the protein foundation of life.
Miller is famed for the results of experiments on amino acid formation in a jar filled with methane, hydrogen and ammonia — his version of the primordial soup. However, his estimates of atmospheric composition were eventually considered inaccurate. The experiment became regarded as a general rather than useful example of how the first organic molecules may have assembled.
But the latest results, derived from samples found in an old box by one of Miller's former graduate students, come from a device that mimicked volcanic conditions now believed to have existed three billion years ago. The findings suggest that amino acids could have formed when lightning struck pools of gas on the flanks of volcanoes, and are a fitting coda for the late father of prebiotic chemistry.
