Caffeine

Caffeine is now good for you, if you drink it regularly. Somehow, I don't think my mum will agree with this research.

Meanwhile, there are suggestions that caffeine should be banned for athletes for ergogenic reasons, whatever that means. Banned for three days before competition, that is.

There seem to be several VRML models of caffeine molecules: 1, 2, 3, 4. Or maybe they are all the same copy floating around.

Here's an interesting tutorial about testing for caffeine in horse doping. Presumably giving your horse M&M's before a race does not count as doping.
