* May 15 – [[Stanley Miller]] publishes results from the [[Miller experiment|Miller–Urey experiment]] in the journal ''[[Science (journal)|Science]]''. These surprise many chemists, by showing that organic molecules present in living organisms can form easily from simple inorganic chemicals.<ref>{{cite journal|jstor=1680569|first=Stanley L.|last=Miller|s2cid=38897285|title=A Production of Amino Acids Under Possible Primitive Earth Conditions|journal=Science|volume=117|year=1953|pages=528–9|doi=10.1126/science.117.3046.528|pmid=13056598|issue=3046|bibcode = 1953Sci...117..528M }}</ref>
