Without a proper chemical check on excitatory messages set off by drugs, the brain never appreciates that it's been satiated...

In SN 2006gy, the sheer mass of the star produced so much core heat and gamma-ray radiation that it created matter and antimatter particle pairs. This blew the star to bits, leaving no cold core behind...

An explosion--which could occur soon or just as easily not--would release deadly gamma radiation, but the finely focused beam in which the rays travel means the danger is likely to pass us by. The fireworks, meanwhile, would be "the best star show in the history of modern civilization," says astronomer Mario Livio of the Space Telescope Science Institute in Baltimore. But after many months, the light would flicker out, and Eta Carinae would be no more. [This article consists of a complex diagram...

But despite having attended a Delta Gamma sorority formal in Boston the previous night, he doesn’t appear to be affected by a lack of sleep.
