Happening Science

I've noticed a slew of interesting science news stories in the last few days.  The New York Times has reports on the rapid developments in growing artificial organs, the developments by chemist Paul Chirik of Princeton that allow iron and to be used in place of platinum as a catalyst in certain reactions (and a similar process that allows cobalt to be used as a catalyst in making plastic), and on confirmation that a meteorite that fell last year in Morocco came from Mars.  And then there's this cool video, via Physics arXiv, showing that liquid droplets hitting a pool will sit on the surface and no coalesce if the surface is vibrating:

The world is simply cool (and getting cooler).
