tl;dr The 50th Mersenne prime was just found by a volunteer of the GIMPS (Great Internet Mersenne Prime Search) project. It is 2^77,232,917-1 and has 23,249,425 digits. Mersenne primes are extremely rare and are always of the form 2^p-1 for some positive integer p. The first four Mersenne primes are 3, 7, 31, and 127.

January looks to be a good month for discovering large prime numbers! As a former contributor to the project it would be great to have a primer on the best way to contribute today, covering the options for CPUs vs GPUs and the various projects for factorizations vs primality tests.

As someone who knows nothing about advanced mathematics, could someone explain why this matters? (i.e. beyond that this is rare and theoretically interesting)

The link has another link to a page describing why this matters:
