Researchers discover new dinosaur fossils
Researchers probing mountains and ancient seas in Antarctica have discovered two previously unknown types of dinosaurs, the National Science Foundation reported Thursday.
The fossilized remains were found less than a week apart on the frozen continent that once had a far warmer climate.
One is an early carnivore, a relative of the fierce Tyrannosaur, that would have lived many millions of years after the other dinosaur, a plant-eating beast, was alive.
The carnivore was found on James Ross Island, off the coast of the Antarctic Peninsula.
Thousands of miles away in the continent's interior, another team found embedded in solid rock what they believe to be the pelvis of a primitive sauropod -- a four-legged, plant-eating dinosaur similar to better-known creatures such as Brachiosaurus and Diplodocus.
Spacewalk ends early after malfunction
A riskier-than-usual spacewalk outside the international space station was cut short Thursday night because of a malfunction that left one of the two crewmen with a warm, damp suit.
Russian cosmonaut Alexander Kaleri made it safely back inside despite the problem with his spacesuit.
Kaleri and American astronaut Michael Foale had left the space station empty when they ventured out, the first time the 5-year-old outpost had ever been unattended during a spacewalk. It was necessitated by the grounding of NASA's shuttle fleet in the wake of the Columbia accident.
The crewmen managed to complete half their work -- primarily installing new scientific experiments outside -- before the cooling device in Kaleri's suit stopped working. The spacewalk was supposed to go 5 1/2 hours; it lasted three hours and 55 minutes.
Normally, a third crew member stays inside during a spacewalk to oversee the systems, watch over the two outside and help them once they re-enter.
FBI adds protections for crime evidence
The FBI banned agents from removing anything from crime scenes or evidence sites after a Justice Department review found 13 agents took chunks of concrete, pieces of metal, U.S. flags and a Tiffany globe paperweight from the rubble of the World Trade Center.
None of the agents has been charged with a crime. One was suspended for 10 days for shipping 80 pounds of debris to his home office, and another is under investigation by the FBI's Office of Professional Responsibility for making misleading statements about what was taken from the debris collection site at the Fresh Kills landfill in Staten Island, N.Y.
The disclosures were contained in a still-confidential report prepared by Glenn A. Fine, the Justice Department inspector general.
