In Egypt, a Rediscovered Pyramid and an Ancient City
Archaeologists announced new finds in Egypt last week, including a 4,000-year-old "missing pyramid" and more remains of Tharu, an ancient fortified city near the Suez Canal.
The pyramid is believed to have been built by King Menkauhor, an obscure pharaoh. It was found in 1842 by German archaeologist Karl Richard Lepsius, only to be lost later to the desert sands.
The 3,000-year-old fortress city, near the modern border town of Rafah, covered about 31 acres and helped guard the Egyptian empire's eastern front in the Sinai Peninsula.
In other news, scientists presented new evidence suggesting that human settlers did not come to New Zealand until around 1300 A.D., or 1,000 years later than previously believed. This conclusion was based on a four-year studying involving radiocarbon dating of bones and seeds.
Meanwhile, in Peru, scientists say ancient skeletons unearthed at a 4,000-year-old archaeological site about 90 miles from Lima suggest that human sacrifice may have been practiced in the Pre-Ceramic period in the Andes mountains, a time formerly thought to have been relatively peaceful.

PODCASTS: From Balloons to Space Stations: Studying Cosmic Rays
Cosmic rays have mysterious qualities about them that scientists continue to research in order to better understand their origins and composition. Dr. Eun-Suk Seo, a professor of physics at the University of Maryland, and her colleagues, fly enormous balloons as large as a football stadium and a volume of 40-million-cubic feet for extended periods over Antarctica to study particles coming from cosmic rays before they break up in the atmosphere.
