From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.

On the outskirts of Albuquerque, New Mexico, scientists are doing something astonishing. They're creating a white dwarf star - not a whole star but enough of one to study in minute detail. As part of his series, "Joe's Big Idea," NPR's Joe Palca introduces us to the astronomer behind this exotic project and explains why he's determined to learn all he can about this interesting stellar object.

Removing all the dangerous bacteria from drinking water would have enormous health benefits for people around the world.

The technologies exist for doing that, but there's a problem: cost.

Now a scientist at the Massachusetts Institute of Technology thinks he's on to a much less expensive way to clean up water.

Try to imagine someone who is supremely calm while at the same time bursting with energy, and you've got a pretty good idea of what Jim Olson is like.

He's a cancer researcher, physician, cyclist, kayaker and cook, not always in that order. He approaches each activity with incredible passion.

But to really understand Olson, you have to watch him in action with patients.
