    1. New property of prime numbers discovered. Primes greater than 5 can end with 1, 3, 7, or 9. The next prime is less likely to end with the same digit, and biased toward one of the remaining three. For instance, a prime ending in 3 is most likely to be followed by a prime ending in 9. The bias evens out as the primes get larger, but only very slowly.

    1. What makes number theory interesting is that problems that are simple to state (at least to mathematicians) are often fiendishly difficult to solve. The most famous such problem, Fermat's last theorem, was postulated in the 17th century. It took until 1993 to prove that it was true.
