On the black hole information paradox

After nearly 30 years of arguing that a black hole destroys everything that falls into it, Stephen Hawking is saying he was wrong. It seems that black holes may after all allow information within them to escape. Hawking will present his latest finding at a conference in Ireland next week.

I didn't see this story back when it was published. The conference was on July 21st, and I'm just now learning about it through the American Physical Society's coverage. It's not yet clear that this new explanation is correct. John Preskill has not yet accepted the encyclopedia in part because he says "I didn't understand the talk." Kip Thorne (Hawking's betting partner) is apparently also unconvinced.

A very accessible (but still technical) discussion of the information paradox can be found on Baez's website.
