  • While environmentally friendly or so-called "green" chemistry has become all the rage in the chemical community, no human chemist can yet match what a single jellyfish gene directs: 238 ordered condensations + 1 cyclization + 1 oxidation, all done in a few minutes in aerated water with no protecting groups, only one slightly toxic byproduct, and essentially 100% yield of an extremely useful product that literally glows green.
