Progress on prime pairs

One of the more famous unsolved questions of mathematics is the twin prime conjecture. There are many “twin prime” pairs of the form (p, p+2), where both p and p+2 are prime numbers. The pair (3, 5), for example. Or (5,7), (11,13), (17,19), (29,31), (10007,10009), or (10000139,10000141). The question is whether there are infinitely many such pairs.

A recent burst of work has seen progress towards answering this question, and a paper on by James Maynard (Centre de recherches mathématiques, Université de Montréal) reports that there are infinitely many pairs of primes separated by at most 600.
