Whoever’s responsible for the Flickr account at the University of Alaska Fairbanks Center for Distance Education has been doing cool things with microscopic photography, including a view of an onion’s outer layers that has a few actively dividing cells evident, a view of frog blood (who knew that, unlike those of mammals, reptile red blood cells have nuclei?), and a shot of a few paramecium swimming around.

And given that it’s a distance learning group that uploaded the pictures, I assume that Flickr is now being used to help provide images in an educational curriculum, which is just plain awesome.
