This week, the remains of a crime scene emerged through the sand near an ancient lake.

I never expected in any dream that I would find the remains of a massacre or the earliest massacre recorded in history.

And a brain sensor that melts away after use.

In the future, we envision a kind of bioresorbable, bio-electronic

medicine, so to speak. Plus, what happens when domesticated chickens go wild? This is the Nature

podcast for January the 21st, 2016. I'm Adam Levy. And I'm Kerry Smith.
