King Tut Tomb Fetuses May Reveal Pharaoh's Mother - Egypt Mummies Moved for DNA Tests; Pharaoh Among Them? - March 30, 2009—Researchers may have finally come face-to-face with the real—and wrinkled—Nefertiti, thanks to sophisticated CT scanning technology.

The object, currently on display in Berlin's Altes Museum, was discovered in 1912 during an excavation of the studio of Egyptian royal sculptor Thutmose.
