Two new primes discovered

Scientific American reports:
Prime numbers have long held a special appeal among the mathematically minded, from the Greek astronomer Eratosthenes, who devised a method for finding primes some 2,200 years ago, to the cryptographers who made them the foundation of today’s encryption protocols. Primes, each of which is divisible only by 1 and itself, have even been subject to claims of numerical ownership: California computer consultant Roger Schlafly patented two of them in 1994.
The actual values of the Mersenne primes have not been announced yet.
