The Mars rover Spirit has made an almost complete recovery from its computer troubles and on Thursday sent back its first new images.
The prospects for its twin, Opportunity, which landed on the opposite side of the planet, also look good. It is now expected to roll off its landing platform onto the dark surface of Meridiani Planum early on Saturday or Sunday - about three or four days earlier than originally predicted.
A long-sought new form of matter has been created for the first time. The matter, called a fermionic condensate, consists of atoms that are ordinarily forbidden to exist in the same quantum state but have been tricked into it by linking into pairs.
A publicity-shy Russian researcher who labors in near-seclusion may have solved one of mathematics' oldest and most abstruse problems, the Poincare Conjecture.
Evidence has been mounting since November 2002 that Grigori "Grisha" Perelman has cracked the 100-year-old problem, which seeks to explain the geometry of three-dimensional space.
If Perelman succeeded, he could be eligible for a $1 million prize offered by the Cambridge, Massachusetts-based Clay Mathematics Institute, formed to identify the world's seven toughest math problems.
A DNA test like the one that apparently helped confirm Saddam Hussein's identity can be done in as little as 12 hours, a forensics expert says.
Damn it, I don't feel even one minute younger.
Not that I really expected that drinking a tiny plastic cup's worth of water purportedly spewed directly from the Fountain of Youth would magically reverse the aging process.
