In a time of bio-metrics, and DNA testing, it may not be surprising that Egypt is working to better identify some of its most famous dead people.
Scientists are checking all of Egypt's royal mummies. The goal is to find which of the mummies are real, and which are decoys. The bodies of Egyptian royalty were often removed to protect them from looting and desecration.
And in June, scientists examined a body that seemed to be that of a king who died in his 60s. It turned out to be a young man who died of an arrow wound. Now they will be using CAT scans and DNA to test more than 40 of the mummies at the Egyptian Museum in Cairo.
