Each week we uncover the most interesting and informative articles from around the world, here are 10 of the coolest stories in science this week.
The life of a black hole
Black holes are among the most mysterious places in the universe; locations where the very fabric of space and time are warped so badly that not even light can escape from them. According to Einstein's theory of general relativity, at their center lies a singularity, a place where the mass of many stars is crushed into a volume with exactly zero size. However, two recent physics papers, published on Dec.10 in the journals Physical Review Letters and Physical Review D, respectively, may make scientists reconsider what we think we know about black holes. Black holes might not last forever, and it's possible that we've completely misunderstood their nature and what they look like at the center, according to the papers. [Read more about the mystery]

What a trick!
Lizards can't breathe underwater — or can they?
Footage of a river anole that was recently filmed in Costa Rica revealed that the species — Anolis oxylophus — possesses a highly unusual ability. The anoles breathe stored oxygen while underwater, something that has never been seen or documented before in lizards. [Read more about the feat.]
Distant cosmic body
A newly discovered object is the most-distant body ever observed in the solar system — and the first object ever found orbiting at more than 100 times the distance from Earth to the sun. [Read more about the object.]
An enormous pyramid-like structure in Indonesia that may represent the remains of an ancient temple hid underground for thousands of years. [Read more about the discovery.]
