sciencehabit writes "To find out if certain dance moves are more attractive to women than others, researchers recruited a bunch of college guys and used motion-capture to create avatars of them dancing. When women watched the avatars (2 videos included in story), the men they found most attractive were those who kept their heads and torsos moving without flailing their arms and legs. The researchers say dancing is thus an honest signal to women of the man's strength and health, just as it is in crabs and hummingbirds, who also move in special ways to attract mates."

ZipK writes "After a few days of bad publicity, Apple has reversed its no cash purchase policy, explaining that the policy was originally implemented to limit the number of iPads an individual could buy during the introductory period of short supply. Now that supply has caught up with demand — and the story has hit front pages and gained national attention — Apple has reversed its policy, and taken the opportunity to put a bow on the story by giving the formerly scorned Diane Campbell a free iPad."

Boy Wunda writes "In just one six-month period in Rio de Janeiro, Brazil, in 2006, 96 newborn babies who were in need of medical care died before they could get help. In many developing nations, these deaths could be prevented simply by providing better ways for medical responders to transport infants properly over rough terrain and keep them alive until they can reach hospitals and clinics. Now, a group of Colorado State University seniors has designed and filed a patent for a medically equipped incubator backpack unit that they believe can reduce baby deaths in medical emergencies both in the United States and in newly industrialized nations."

DarkKnightRadick writes "An undergrad student at the University of Utrecht, Marianne Heida, has found evidence of a supermassive black hole being tossed out of its galaxy. According to the article, the black hole — which has a mass equivalent to one billion suns — is possibly the culmination of two galaxies merging (or colliding, depending on how you like to look at it) and their black holes merging, creating one supermassive beast. The black hole was found using the Chandra Source Catalog (from the Chandra X-Ray Observatory). The direction of the expulsion is also possibly indicative of the direction of rotation of the two black holes as they circled each other before merging."

thecarchik writes "Night vision systems are already available in the higher-end luxury sedans from companies like Toyota, Volvo, BMW, and Mercedes-Benz. It's expensive technology that few drivers can afford, and at $4,000 for the system without a display, it's a pricey upgrade. That may all change soon, as DARPA-funded scientists have developed a cheap way to turn any infrared light into visible light with a thin film."

An anonymous reader tips a PC Authority review of some of the biggest technical goofs of all time. "As any computer programmer will tell you, some of the most confusing and complex issues can stem from the simplest of errors. This article looking back at history's big technical mistakes includes some interesting trivia, such as NASA's failure to convert measurements to metric, resulting in the Mars Climate Orbiter being torn apart by the Martian atmosphere. Then there is the infamous Intel Pentium floating point fiasco, which cost the company $450m in direct costs, a battering on the world's stock exchanges, and a huge black mark on its reputation. Also on the list is Iridium, the global satellite phone network that promised to make phones work anywhere on the planet, but required 77 satellites to be launched into space."

The Georgia House Judiciary Committee took up a bill that would "prohibit requiring a person to be implanted with a microchip," and would make violating the ban a misdemeanor. Things started to get weird at the hearing when a woman who described herself as a resident of DeKalb County told the committee, "I'm also one of the people in Georgia who has a microchip." Not sure of what she was trying to say, she was allowed to continue and added, "Microchips are like little beepers. Just imagine, if you will, having a beeper in your rectum or genital area, the most sensitive area of your body. And your beeper numbers displayed on billboards throughout the city. All done without your permission." Further prodding revealed that the woman's co-workers would torture her by activating the chips with their cell phones and that the chips were implanted by "researchers with the federal government." The committee thanked the woman for her input, and later approved the bill.

While it targets most popular MMORPGs, some popular games like Lineage were left off the list."
