Not such a bad mutation

The New York Times is reporting that UCSF scientists have identified a tie between a genetic mutation and the need for less sleep. The research only involved two subjects, but it's the first time a mutation has been linked to sleep duration in humans - and one prominent sleep researcher is calling it a "landmark study."

I have a newborn at home and would love a body that needed only six (or fewer) hours of sleep at night. In other words, this is one genetic mutation I wouldn't mind having!
