Friday beautiful science

This Friday's beautiful science is entirely being hosted here. While at the American Society for Microbiology meeting in Toronto, I saw a talk that discussed the amount of bacterial biomass on earth. He showed a video that animated some NASA data showing photosynthesis in the oceans. I've linked to one of them here. (It's an mpeg owned by NASA, and no one has put it up on Youtube yet, so you'll have to click through). It shows distribution of photosynthetic bacteria in the oceans, and seasonal changes. Very cool. There are more cool NASA videos here.

I'll have more posts next week when I return home and have a more reliable internet connection.
