According to the Boston Globe, swine flu has been confirmed in both Kennebec and York Counties. Also, I have it on good authority that WHO will raise the pandemic threat level to 5 on a 6 level scale at 3 p.m. EST.

Gamma-ray bursts are the universe's most luminous explosions. Most occur when massive stars run out of nuclear fuel. As their cores collapse into a black hole or neutron star, gas jets, driven by processes not fully understood, punch through the star and blast into space. There, they strike gas previously shed by the star and heat it, which generates short- lived afterglows in other wavelengths.
