Mice roar message: genetic change happens fast

While looks can be deceiving, heredity is revealing, and two scientists who've studied the genetic makeup of a common field mouse report that what's most revealing to them is how fast both genes and morphology can change.

Cassini Is On The Trail Of A Runaway Mystery

cassini-is-on-the-trail-of-a-runaway-mysteryNASA scientists are on the trail of Iapetus' mysterious dark side, which seems to be home to a bizarre "runaway" process that is transporting vaporized water ice from the dark areas to the white areas of the Saturnian moon.

This "thermal segregation" model may explain many details of the moon's strange and dramatically two-toned appearance, which have been revealed exquisitely in images collected during a recent close flyby of Iapetus by NASA's Cassini spacecraft.

Infrared observations from the flyby confirm that the dark material is warm enough (approximately minus    ... Read Full Article

Glowing Mice Light The Way To Understanding Type 2 Diabetes

glowing-mice-light-the-way-to-understanding-type-2-diabetesWith the help of genetically engineered mice whose livers turned into glowing light bulbs, researchers at the Salk Institute for Biological Studies have illuminated the underpinnings of an insidious and growing health concern-- type II diabetes.

In the study published in the September 5 advanced online edition of Nature, the researchers report that a protein called TORC2 serves as a    Read Full Article
