MIT gestural computing makes multitouch look old hat -- Engadget

The display consists of alternating LCD and visual sensor elements. Each LCD element alternates between displaying an image and emitting a pattern which reflects off any nearby surface (such as a hand) and is detected by the sensing elements. Using this approach, the group was able to develop a demonstration of gesture-based computing.

BBC News - Making the first computer virus

Dr. Fred Cohen created the first computer virus more than 26 years ago before pioneering ways to fight malicious code. As a student he that a neighbouring university had created a Trojan, but immediately realized that if he could make the code self-replicating it could infect spread itself. He approached a computer security expert at the university with his idea and a request to build one to verify the idea. After creating the virus, he spent the next five years trying to figure out ways to protect computers from the very thing he knew others would soon create.

This concept PC takes the idea of scribbling an idea on a napkin a step farther by making the "napkin" a touch-sensitive e-paper sheet RF-linked to a nearby receiver as shown in this image. The base station can then be linked to a regular computer so that multiple base stations can be linked. Multiple napkins can be linked to make a larger writing surface. The RF link is inductive so the napkin doesn't need a transmitter, and using e-paper means the display is passive, not active so requires minimal power.

Multi-touch display can 'see' objects too - A computer screen that also acts as a two-handed touch interface and a crude infrared camera has been developed by researchers at Microsoft's labs in the UK. The technology – dubbed ThinSight – was developed by adding an extra layer of electronics behind a normal laptop screen. This adds a couple of centimetres to the overall thickness, but completely transforms its abilities. The screen "sees" by using a grid of paired infrared sensors and transmitters that sit just behind the backlight of the laptop's LCD panel. The sensors can form crude images when infrared light bounces off an object (see images, right). This could allow the screen to identify hand gestures or to see objects, and let them interact with onscreen images.

Are women being scared away from math, science, and engineering fields? - Have you ever felt outnumbered? Like there are just not that many people like you around? We’ve all felt outnumbered in one situation or another and walking into a situation in which you sense the possibility of being ostracized or isolated can be quite threatening. One group that may experience this kind of threat is women who participate in math, science, and engineering (MSE) settings- settings in which the gender ratio is approximately 3 men to every 1 woman. Mary Murphy argues that the organization of Math, Science and Engineering environments themselves plays a significant role in contributing to this gap. Murphy contends that situational cues (i.e. being outnumbered) may contribute to a decrease in women’s performance expectations, as well as their actual performance.

The researchers then submerged a fraction of a gram of the aerogel in a solution of mercury-contaminated water and found that the gel removed more than 99.99 percent of the heavy metal. The researchers believe that these gels can be used not only for this kind of environmental cleanup but also to remove impurities from hydrogen gas that could damage the catalysts in potential hydrogen fuel cells.
Lithium and bone healing - Researchers have described a novel molecular pathway that may have a critical role in bone healing and have suggested that lithium, which affects this pathway, has the potential to improve fracture healing.
Web Site Archives the Dead of MySpace - Somewhere deep in cyberspace, where reality blurs into fiction and the living greet the dead, there are ghosts. They live in a virtual graveyard without tombstones or flowers. They drift among the shadows of the people they used to be, and the pieces they left behind.

Nanotubes strengthen artificial muscles - BEST known as the ultra-strong material that might one day form the cables of a "space elevator" capable of raising people into Earth orbit, carbon nanotubes also have a springy side. The discovery that nanotubes keep bouncing back after being compressed repeatedly means this exotic form of carbon may be just the thing to give artificial muscles some extra strength

Exfoliation produces lighter, cheaper solar cells - An ultra-thin solar cell that could provide a cheaper, lighter alternative to existing devices has been created by researchers in the US. James Zahler from Aonex Technologies, together with colleagues from Harry Atwater's group at the California Institute of Technology and researchers at EMCORE PhotoVoltaics made the device by replacing the relatively thick semiconductor substrate normally used in solar cells with a thin "wafer-bonded" substrate. This means the new device is considerable cheaper and lighter than conventional solar cells.

A Better Brain Scanner - New brain scanners promise to deliver images of higher resolution than any now available from a commercial instrument. By using multiple sensors placed close to the head, the device can generate accurate images in less time, which could ultimately aid in the diagnosis of diseases such as Alzheimer's and epilepsy. Medical imaging giant Siemens is developing a commercial version of the technology.
Saving Neurons and Memories - Scientists have shown that a gene called SIRT1 and a plant compound found in red wine called resveratrol can protect against neuron degeneration in a mouse model of Alzheimer's disease and amyotrophic lateral sclerosis. The researchers demonstrated that activating SIRT1 and injecting resveratrol, which have both been previously associated with life-span extension in lower organisms, can also prevent cognitive problems in the mice.

Queen Bees "Brainwash" Workers With Chemicals - A new study suggests the domineering matriarch regulates her daughters' brain activity to ensure her own survival. One of the parts of the pheromone is homovanillyl alcohol (HVA). It interacts with a neurotransmitter called dopamine, which is found in the brains of insects and animals. In a mechanism that's still not understood, the pheromone may be able to block dopamine and prevent the young worker bees from avoiding negative stimuli. Worker bees - which surround and dote on the queen - are all female, and drone bees are male.

Parents Steal Children's Identities - On paper, Randy Waldron Jr. was $2.5 million in debt and a convicted felon. He owed hundreds of thousands of dollars to credit card companies, owed back taxes to the state of Florida, and had liens and civil actions against him. In reality, Waldron was a 17-year-old high school junior living in New Hampshire, who in 1998 couldn't get a student loan for college or a credit card because his Social Security number had been stolen when he was just 1 year old. Making matters worse, the man who stole Waldron's identity was his father.
Jetson-Like Flying Car in Production - Moller International, a company founded by a UC Davis professor devoted to developing a flying car, announced in a statement recently that it has begun production for its "Jetsons-like M200G Volantor, a small airborne, two passenger, saucer-shaped vehicle that is designed to take off and land vertically."

Antique engines inspire nano chip - The blueprint for a tiny, ultra-robust mechanical computer has been outlined by US researchers. The energy-efficient nano computer is inspired by ideas about computing first put forward nearly 200 years ago. Chips based on the design could be used in places, such as car engines, where silicon can be too delicate.

Denser Data Storage - Scientists have produced a novel type of nanoparticle that they say could make it possible to dramatically increase magnetic-based data storage on future generations of computer hard drives. The researchers at Brown University and Sandia National Laboratories have announced new ways to create iron-platinum nanorods and nanowires. The materials can potentially provide a way to make far denser magnetic media. In doing so, the new materials could make possible devices that do not have the limits that many scientist anticipate conventional magnetic storage technologies will soon encounter.
Don't I Know You? - It only takes a millisecond to recognize celebrities on TV while flipping through the channels: Rachel Ray hawking coffee, David Hasselhoff judging a talent show, or Charles Gibson relaying the latest tragedy in Iraq. While it seems easy, recognizing those faces is a cognitively complex task. Your brain must identify the object you're seeing as a face, regardless of the size or angle; interpret the expression encoded by the particular arrangement of eyes and mouth; and access the memory part of the brain to determine if the face is familiar. By combining two of the most important tools in neuroscience--brain imaging and electrical recordings from single brain cells--scientists are poised to finally understand how the brain performs these complex computations.

Rideau Canal named a global gem - It is the world's largest skating rink, the regular inclusion on tourist ‘must-see' lists, and it is now officially one of Canada's global gems. The Rideau Canal has been named a World Heritage Site by UNESCO, putting it in the esteemed company of the Rocky Mountains, Gros Morne National Park, Head-Smashed-In Buffalo Jump, Old Quebec and the Waterton Glacier. But the Canadian treasure, which turns 175 this year, is not on the list because of national iconography or winter fun. UNESCO says the Rideau Canal is no less than a witness to the violent struggle to control the entire North American continent.
'Fat-shaping' could have health benefits - Researchers have figured out how to remove fat from one part of the body and make it grow in another part — at least in mice — and say their findings could benefit health as well as beauty. Their findings also shed light on how and why stressed-out people so often gain weight.
We're both the chatty sex - Men talk every bit as much as women do, U.S. researchers say after painstakingly counting every word that 400 volunteers spoke. Their study, published on Thursday in the journal Science, challenges the common wisdom that women are somehow biologically programmed to talk more – but the researchers said people do often fulfill gender roles when it comes to subject matter."Women and men both use on average about 16,000 words per day, with very large individual differences around this mean," the researchers, led by psychologist Matthias Mehl of the University of Arizona, wrote.
