Egyptian archaeologists had found what could be the oldest human footprint in history in the country's western desert, the Arab country's antiquities' chief said.

"This could go back about two million years," said Zahi Hawass, the Secretary-General of the Egyptian Supreme Council of Antiquities. "It could be the most important discovery in Egypt," he said on Monday.

Archaeologists found the footprint, imprinted on mud and then hardened into rock, while exploring a prehistoric site in Siwa, an oasis.

Scientists were using carbon tests on plants found in the rock to determine its exact age, Dr Hawass said...

The Putnam Museum is sending two of its mummies on a field trip in hopes of learning more about their history.

The mummies, described as among the Davenport museum's most prized and popular possessions, will be carefully removed from their cases on Tuesday and taken by ambulance to Genesis Medical Centre's West Central Park Avenue Campus, where they will undergo CT scans.

The scans, being donated by the hospital, are expected to reveal new information about the mummies, such as their ages, genders and maybe even how they died...

One of the mummies, believed to be 3,000 years old, is named Isis and rests in the museum's lower gallery. Another unnamed mummy rests beside Isis and also will be tested.

The museum hopes to post new information about their history by November, when the mummies will be placed in new humidity controlled cases and their displays updated with new interactive features...
