It shuttles in and out of the nucleus as part of a "nuclear experience" that helps regulate cell growth and division, University of Illinois scientists say. (Proceedings of the National Academy of Sciences, 12-00)
The blowup of CaliforniaÃs electricity system demonstrates how soaring demand combined with artificially low prices can disrupt a commodity that everyone relies on ñ and takes for granted.

(Journal of Neuroscience, 1-01)
Cornell University astronomers hope that surface details as small as a hand-size rock will be captured by the camera in NASA's NEAR Shoemaker in the final few minutes before it bumps down on the boulder-strewn surface of Eros Feb. 12.
