Cockroach-Like Robot to Help Explain Animal Movement
neutron_p writes "A cockroach-like robot named RHex is the starting point for a major project to understand animals' most distinguishing trait: how they move without falling over. Researchers from several universities will focus on RHex, a short, six-legged robot that scampers like a cockroach, as a working model of the principles they're seeking to uncover. By tweaking the robot and using it as a physical model, they hope to tease apart the complex neural and muscular networks in insects." -
Spinach May Soon Power Mobile Devices
neutron_p writes "For the first time, MIT researchers have incorporated a plant's ability to convert sunlight to energy into a solid-state electronic "spinach sandwich" device that may one day power laptops and cell phones." -
Transmeta TM8800 And Ultraportable Announced
yerdaddie writes "The just-released Transmeta TM8800 has been integrated into a new ultraportable from Sharp. The smaller 90nm variety clocks and performs better than the older 130nm TM86XX Efficeons. It also seems the Orion Multisystems personal clusters discussed earlier on slashdot will be built around this processor variant. Hopefully Transmeta will be releasing a developer kit soon for eager hardware hackers." -
DVD / Hard Drive Recorder With 28-Day Capacity
fenimor writes "Panasonic today unveiled new DVD-recoders with astonishing 709 hours video recording capacity. The top model has onboard components of a good PC: 400GB hard drive, Ethernet port, broadband receiver, SD Memory Card slot, and a PCMCIA card. The DVD recorder is the fastest in the industry as it can record a one-hour program onto DVD-R disc in just 56 seconds. Internet access allows users to program recording through cell phones or PCs while away from home." -
World's Largest Working Computing Grid
fenimor writes "UK particle physicists claim that they will demonstrate the world's largest, working computing Grid with over 6,000 computers at 78 sites internationally. The Large Hadron Collider Computing Grid is built to deal with 15 Petabytes of data each year from the Large Hadron Collider (LHC), currently under construction at CERN in Geneva. 'This is a great achievement for particle physics and for e-Science,' says Professor Tony Doyle, leader of GridPP. 'Our next aim is to scale up the computing power available by a factor of ten'." -
Women See Colors Better
fenimor writes "The results of the study by researchers at the Biodesign Institute at Arizona State University, suggests that natural genetic selection has provided women with a frequent ability to better discriminate between colors than men. 'Normally, this degree of genetic variation is suppressed through natural selection,' says Brian Verrelli, a researcher at ASU. 'In this case, nature is supporting a high degree of variation instead.' Because women have two X chromosomes, women can receive one chromosome with the typical configuration of the red vision gene while the other chromosome receives a slight variation. By contrast, men have one X chromosome, and any variation in the single red gene that they receive reduces their ability to distinguish between red and green." -
First 'Atomic Air Force' Observed
SeaDour writes "From the National Institute of Standards and Technology (the people who brought you the atomic clock) and the Unviersity of Colorado at Boulder (location of the world's first Bose-Einstein Condensate and Fermionic Condensate) comes the world's first observation of atoms "flying in formation". Atoms are normally expected to fly around through empty space quite haphazardly, constantly colliding with one another. But thanks to precision laser pulses and extremely cold temperatures, Jun Ye's team was able to correograph strontium atoms into the shape of a cube as they travelled across a vacuum chamber. "This 'really bizarre' behavior is believed to occur with all atoms under similar conditions."" -
Revolutionary Spam Firewall Developed
psy writes "physorg has a story on a new spam firewall developed at The University of Queensland. The new technology is the only true spam firewall in existence, according to co-developer Matthew Sullivan. "Existing anti-spam software filters out spam whereas ours puts up a firewall, stopping all email traffic and only allowing real mail through," said Mr Sullivan. "In addition, our technology is accurate and fast. We recently completed a successful trial of a key layer of the spam firewall and it processed the emails at 90 messages per second, misclassifying only one out of 25,000 emails." "It turned out that the software was even better than us, picking up spam we'd incorrectly classified as legitimate emails." -
100 Terabyte 3.5-inch Optical Storage
ignipotentis writes "According to PhysOrg we are close to being able to record our entire lives on a single 3.5" optical disc. This article talks about using ultraviolet light since focused laser beam is smaller in diameter than other frequencies of light. The expected cost per drive upon production is $570-$750 with discs costing $45." -
