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: Expanding With the Cosmos
Using the Atacama Cosmology Telescope (ATC), a 6.5-meter microwave collector in Chile, cosmologists are piecing together the early history of the known universe. In an exclusive American Scientist interview, Arthur Kosowsky—a member of the ATC team and a professor in the Department of Physics and Astronomy at the University of Pittsburgh—discusses how he is using ATC to reach back in time billions of years to search for gravitational waves that could verify inflation and reveal unprecedented details about how the cosmos was born.
