Bounded gaps between primes
Zhang proved that some gap below 70 million recurs infinitely often, the first finite bound ever. Within a year, the Polymath8 project and Maynard's simpler multidimensional sieve brought the bound down to 246. It is one of the clearest recent examples of a public collaboration improving a result in the open. Under the Elliott–Halberstam conjecture the bound drops to 6.
