Three years ago, a report from the National Academy of Sciences exposed serious problems in the nation's forensic science community. It found not only a lack of peer-reviewed science in the field, but also insufficient oversight in crime laboratories.

And I'm Audie Cornish. We begin this hour with growing talk of a cease fire in the fight between Israel and Hamas militants in the Gaza Strip, but at this point, it is still just talk.

New York City lost almost 10,000 trees from the winds of Superstorm Sandy and the nor'easter that followed. That's far more trees lost in the city than in any other storm for which tree damage was recorded.
Walking through Central Park, Ken Chaya peers past a stone arch, observing the damage and uprooting of about 800 trees. He knows more about the park's trees than just about anybody else; he created a map that charts every single one of the roughly 20,000 trees.
