Science for science writers
Science News blogs from Austin, Texas, where the 47th annual New Horizons in Science meeting is taking place. Freelance Laura Beil describes how Skip Garner began his accidental journey into scientific misconduct investigation after he developed a computer program that could, as he put it, “help a physicist understand medicine,” he told writers in the audience at the Council for the Advancement of Science Writing symposium. Got milk tolerance? Your ability to digest lactose as an adult is relatively new in the human species. And, said John Hawks of the University of Wisconsin-Madison, provides evidence of rapid evolution over the past 10,000 years, Elizabeth Quill reports in this blog from the meeting.

(They contend that they are working on implant devices for the injured bodies of people like Vietnam vets, says Griffith, but if you get them drunk they’ll confess that the real aim is to make cyborgs of us all.)

Itch
When it comes to sensory information detected by the body, pain is king, and itch is the court jester. But that insistent, tingly feeling—satisfied only by a scratch—is anything but funny to the millions of people who suffer from it chronically.
