GIMPS has discovered a new largest known prime number: 2^{82589933}1 (24,862,048 digits) In 1919 Brun showed that the sum of the reciprocals of the twin primes converges to a sum now called Brun's Constant: (1/3 + 1/5) + (1/5 + 1/7) + (1/11 + 1/13) + (1/17 + 1/19) + ...Had this series diverged, then we would have a proof of the twin primes conjecture. But since it convereges, we do not yet know if there are infinitely many twin primes. By calculating the twin primes up to 10^{14} (and discovering the infamous Pentium bug along the way), Nicely heuristically estimated Brun's constant to be 1.902160578. More recently he has improved this estimate to 1.9021605824 by using the twins to 1.6^{.}10^{15}.
