     What killed King Tut? Historians and scientists have long believed that ancient Egypt's most famous king

was probably murdered. But a recent scientific study claims to have found a different solution to this more

than 3 300-year-old mystery.

     Tut's full name was Tutankhamen. He was just 9 years old when he became ruler of Egypt in 1348 B.C.

His treasure-packed tomb was revealed (展现) to the world almost a century ago. Tut's tomb was filled with

royal riches, including a solid-gold coffin, a gold mask, and piles of jewelry. It made him one of the best-

known Egyptian kings of all time.

     But Tut did not have much time to enjoy his vast wealth. His reign (执政) was cut short at the age of 19.

Many experts have thought that Tut was killed by one of his advisers, named Ay, who wanted the throne for

himself. Thanks to a major modern science project, it seems that Ay is off the hook.

     Researchers set out to solve the mystery of King Tut's death by using the tools of science. They began

their investigation of Tut's well-preserved mummy by conducting an autopsy (尸体解剖), which is an in-depth

medical examination to determine how someone died. The king's autopsy included DNA tests and electronic

scans of his remains.

     Scientist Carsten Pusch conducted the tests on Tut for the new study. A scan of Tut's mummy showed

an unhealed fracture (骨折) in his leg bone. He thinks a broken leg contributed to the young king's death. The

DNA also indicates that the ruler had an illness that causes bones to go bad. More than 100 walking sticks

were found in King Tut's tomb. This supports the autopsy findings. Many of the sticks were well-worn,

showing regular use. But how could a person die from a simple broken leg? Pusch also found DNA evidence

in Tut's remains that indicates he had malaria, a disease carried by mosquitoes. Malaria severely weakens the

immune system. Finally, the young ruler was just too weak to heal.
