Confirmada a descoberta do 45º e do 46º números primos de Mersenne — isto é, que podem ser expressos na forma 2^p-1. Mersenne 45 tem a forma 2^43.112.609-1, e Mersenne 46,  2^37.156.667-1. Ambos foram descobertos graçs ao GIMPS, um sistema de computação distribuída, e o Mersenne 45, por ser o primeiro número primo com mais de 10 milhões de dígitos ( 12.987.189 para ser exato), faz jus a um prêmio de US$ 100 mil.
O próximo prêmio, de US$ 150 mil, está prometido para o primeiro primo de 100 milhões de dígitos. Quem quiser uma parte da boloada quando (e se)  ela for ganha, pode baixar o software do site GIMPS e pôr a máquiina pra trabalhar.
