Early human-like residents of Europe may have arrived out of Asia, rather than just Africa.
An international team of researchers reports in Monday's online edition of Proceedings of the National Academy of Sciences that Asians appear to have played a larger part in the settlement of Europe than did Africans.
Flipping one genetic switch in the brains of female mice makes them behave like sex-crazed males. The finding implies that females' brains have the same circuit that governs sexual behaviour in male mice - and that it's simple to convert one to the other

| The 'Jetsons-like' flying machine is the size of a small car and boasts a top speed of 100mph

Whizzing to work in a flying saucer seems like a futuristic fantasy reminiscent of George Jetson and his space-age pals.
But that reality may be one step closer after US company Moller International embarked on a wacky 30-year quest to build a personal flying pod.

By the time Rick Deacon was done Sunday showing hackers in Las Vegas how to commandeer MySpace profile pages, he was evicted from the social networking website and the weakness fixed.
The US college student uncovered a MySpace vulnerability months ago and shared his discovery at DefCon, the largest gathering of computer hackers in the world.
"Obviously they weren't happy about it," Deacon said after he finished his presentation, checked his e-mail and saw a message from MySpace telling him his account was deleted for "violating terms of service."
"In retrospect, I should have used a dummy account."
Deacon's attack relied on duping MySpace users into clicking rigged links, perhaps in online forums or bulletin boards, which routed them to a file that steals passwords and identifying information stored in software "cookies."
A human skull from a Romanian bear cave is shaking up ideas about ancient sex.
The Homo sapiens skull has a distinctive feature previously found only in Neandertals, providing further evidence of interbreeding between the two species, according to a new study.
The human cranium was found during World War II mining operations in 1942, in a cave littered with Ice Age cave bear remains.
Recently the fossil was radiocarbon dated to 33,000 years ago and thoroughly examined, revealing the controversial anatomical feature.

Former astronaut Rusty Schweickart has already earned his place in the history books by flying in space on the Apollo 9 mission. However, should an asteroid crash into the Earth anytime soon, killing millions and causing catastrophic damage, he'll also be remembered as the guy whose warnings we ignored.

Mexican archaeologists using ground-penetrating radar have detected underground chambers they believe contain the remains of Emperor Ahuizotl, who ruled the Aztecs when Columbus landed in the New World. It would be the first tomb of an Aztec ruler ever found.
The find could provide an extraordinary window into Aztec civilization at its apogee. Ahuizotl (ah-WEE-zoh-tuhl), an empire-builder who extended the Aztecs' reach as far as Guatemala, was the last emperor to complete his rule before the Spanish Conquest.
Excavations of an underwater Stone Age archaeological settlement dating back 8000 years are taking place at the National Oceanography Centre, Southampton this week (30 July - 3 August 2007).
Maritime archaeologists from the Hampshire and Wight Trust for Maritime Archaeology (HWTMA) have been working at the site just off the Isle of Wight coast. Divers working at depths of 11 metres have raised sections of the seabed, which have been brought to the NOCS laboratories for excavation.
