Scientist Smackdown: Did King Tut Die of Malaria or Sickle Cell?

What struck down ancient Egypt's King Tutankhamen at the tender age of 19? Just this winter, Egyptian researchers seemed to think they had a definitive answer. After years of genetic tests and CT scans, they concluded that royal incest had produced a sickly boy with a bone disorder, and argued that a malaria-bearing parasite finished him off. But now a team of German researchers is arguing that the observations actually point to death from the inherited blood disorder sickle cell disease (SCD).
