Miller-Urey experiments revisited
Found this article in this month's Chemistry World:
The gist is basically that after Miller's death, his student inherited the office and lab and found details of some experiments that were never finished and hence reported. By simulating volcanic conditions this time (using hydrogen sulphide) they were able to create the sulphur-containing amino acids.
Not a long article, but worth a read for anyone interested in abiogenesis.
