They say the high-energy X-ray beams from a synchrotron will provide molecular information about what is inside the mummy of the little girl. Argonne says it's the first time the beams have been used in this way.
Researchers say the technology allows them to study what's inside the mummy while leaving the 5-year-old girl's remains and wrappings intact.
Scientists examined the rare find on Monday in the hopes of learning more about how the girl died. And they say studying the wrapping materials may shed new light on ancient Egyptian culture.
