Tycho Brahe Died from Pee, Not Poison

Two years after Tycho Brahe was exhumed from his grave in Prague, chemical analyses of his corpse show that mercury poisoning did not kill the prolific 16th-century astronomer. The results should put to bed rumors that Brahe was murdered when he most likely died of a burst bladder. [Full Story]
