From enraptured voles and space robots on the moon to brain gears and dense objects, it was a heck of a week in science. Let's take a look at some of the most interesting developments over the past seven days.
It's one of the great paradoxes of evolution. Humans have demonstrated that having large brains are key to our evolutionary success, and yet such brains are extremely rare in other animals. Most get by on tiny brains, and ...
