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."

Ant notes a piece up on WBUR Boston addressing theories to explain the universal human experience that time seems to pass faster as you get older. Here's the 9-minute audio (MP3). Several explanations are tried out: that brains lay down more information for novel experiences; that the "clock" for nerve impulses in aging brains runs slower; and that each interval of time represents a diminishing fraction of life as we age.

According to a report from Japanese publication Nikkei Net, Nintendo's New Super Mario Bros. Wii has now sold 10 million copies worldwide. The game needed only 45 days to pass the already impressive sales numbers of Super Mario Galaxy. Quoting Gamasutra: "NSMB Wii has sold 3 million units in Japan, where it launched on December 3; 3 million copies in Europe, where it launched November 20, and 4.5 million units in North America, where it launched November 15. Super Mario Galaxy has sold 4.1 million units in North America since 2007. The game's design hearkens back to the two-dimensional, side-scrolling style of earlier Mario titles ... The numbers would seem to suggest that these traits successfully generated more mass appeal for NSMB Wii than for the three-dimensional and far less familiar Super Mario Galaxy, which sent the plumber navigating more innovative spherical space environments."

An anonymous reader writes with this excerpt from an AP report: "Australian scientists have discovered an octopus in Indonesia that collects coconut shells for shelter — unusually sophisticated behavior that the researchers believe is the first evidence of tool use in an invertebrate animal. The scientists filmed the veined octopus, Amphioctopus marginatus, selecting halved coconut shells from the sea floor, emptying them out, carrying them under their bodies up to 65 feet (20 meters), and assembling two shells together to make a spherical hiding spot. ... 'I was gobsmacked,' said Finn, a research biologist at the museum who specializes in cephalopods. 'I mean, I've seen a lot of octopuses hiding in shells, but I've never seen one that grabs it up and jogs across the sea floor. I was trying hard not to laugh.'"

coondoggie writes "Soldiers may go into battle better prepared to handle equipment and with a greater knowledge of their surroundings after an intellectual property licensing deal Monday between Microsoft and Lockheed Martin that will deepen the defense giant's access to visual simulation technology. The intellectual property agreement between the two focuses on Microsoft ESP, a games-based visual simulation software platform for the PC."

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."

Harry writes "Some bad decisions in game console design get made over and over. (How many early systems had nightmarish controllers?) Others are uniquely inexplicable. (Like the Game Boy Advance's lack of a headphone jack.) Some stem from companies being too clever for their own good. (Like the way the RCA Studio II and Atari 5200 drew their power through their RF switches.) Benj Edwards has rounded up a few classic examples, and has attempted to figure out what was going on in the designers' heads — and what we can learn from their mistakes."
