Synchronicity

Cool! Listen to the end for some interesting potential applications.

You can read the paper, A synchronized quorum of genetic clocks, in this week's edition of the journal Nature.

Incidentally, although some of the YouTube comments seem to think that 'Mexican Wave' is some sort of racist comment this is the term most widely used in England for a synchronised 'wave' in a large sports stadium (usually just called 'the wave' here in the US). In England this sort of behavior was not common until it was seen on TV during the 1986 world cup in Mexico and so it became associated with Mexico even though it hardly originated there.
