Helpful Mutations Didn't Sweep Through Early Humans
Humans probably didn’t get swept up in evolution.
Scientists have favored a model of evolution in which beneficial gene mutations quickly and dramatically sweep through a population due to the evolutionary advantages they confer. Such mutations would become nearly universal in a population. But this selective sweep model may not be accurate for humans, a new study indicates. Human evolution likely followed a more subtle and complicated path, say population geneticists Molly Przeworski of the University of Chicago and Guy Sella of Hebrew University of Jerusalem and colleagues.

Three Years Later, GM Answers Sync's Call
Three years after Ford made itself the leader in vehicle connectivity with Sync, General Motors has answered the call with MyLink.
The system builds upon GM’s excellent if limited OnStar to provide text messaging, e-mail and traffic advisories in addition to online services like Pandora and Stitcher. Like Sync, the General’s system links the driver’s cell phone to the vehicle’s voice-recognition software, audio system and navi for fully integrated infotainment.
General Motors pioneered in-car telematics when it unveiled OnStar in 1996, but it has lost ground to Ford’s Sync as the market for...
