The Internet revolution of the 1990s –and resulting worker productivity increases — created fundamental changes that are at least partly responsible for why the recent downturn was so mild, some economists believe.
A new type of analog processor that is compact while offering extremely fast computations for image processing may lead to the creation of an artificial eye to replace damaged human retinas.
The cellular nonlinear network (CNN) analog computer chip is integrated with a camera to produce an image processor. The 1 cm-square CNN chip can increase processing speed while reducing the power requirements over standard digital chips by two to… read more
Duke University Medical Center researchers have discovered the brain region that automatically watches for patterns in sequences of events.
In an article posted online April 8, 2002 in Nature Neuroscience, researchers Scott Huettel, Beau Mack and Gregory McCarthy reported experiments in which they asked subjects to watch simple random sequences of a circle or a square flash onto a screen. During the experiments, the scientists imaged the subjects’ brains using… read more
Researchers at Cedars-Sinai Medical Center in Los Angeles have transplanted a man’s own brain stem cells to stop the trembling and rigid muscles that mark Parkinson’s disease. The treatment has been effective for two years, with an initial 58 percent increase in dopamine.
Other researchers are experimenting to see if brain cells can be regenerated using stem cells The study may be used in the debate over the use… read more
The Massachusetts Institute of Technology, funded by the US Army, is setting up a $50 million research center known as the Institute for Soldier Nanotechnologies (ISN) to develop the soldier of the future.
The center will develop futuristic cyborg technologies, such as devices that can heal soldiers, nearly invisible uniforms, clothing that can become a rigid cast when a soldier breaks a leg, shoes with built-in power packs to endow… read more
The AAAS has posted an audio file of remarks made by K. Eric Drexler, Senior Research Fellow at the Institute for Molecular Manufacturing and Foresight Board Chair, who spoke on a panel discussion during a symposium on “The War On Terrorism: What Does It Mean for Science?,” held on 18 December 2001 in Washington, D.C.
The sharpest images ever achieved by optical means have been produced by researchers at the Max Planck Institute for Biophysical Chemistry, who have imaged clumps of bacteria just 33 nanometres across, equivalent to 1/23 of the wavelength of light used to illuminate them.
The researchers hope to achieve a resolution of around 17 nanometres, using ultraviolet light. Practical devices are expected within two or three years, which could have microlithography… read more
The Cyc knowledge base will acquire knowledge of 100 million things — about the number a typical person knows about the world — in five years, says Cycorp CEO and founder Doug Lenat. “It’s difficult to predict the course thereafter,” he adds.
Biotech company Tosk says it can add genes to mammalian cells with unprecedented efficiency with the help of fruit fly DNA that can jump in and out of chromosomes.
Introducing genes into mammals is laborious and expensive at present. The new method promises to make genetically modified mammals cheap and easy and could even be used to correct genetic faults in people.
GM mammals are usually made by injecting… read more
Researchers at the University of California at Berkeley are developing self-sustaining network nodes measuring millimeters in length, complete with sensors and communications. This “smart dust” could be used for environmental monitoring, health, security, distributed processing, tracking and new user interfaces, including invisible keyboards, gesture control and 3D input devices.Problems in implementing smart dust include power (tiny batteries and more efficient chips are being developed) and communications (optical links via optical… read more
The Pentagon is replacing soldiers with sensors, vehicles and weapons that can be operated by remote control or are autonomous.
These devices can function as heat detectors, radar, cameras, and microphones, for example, and can reveal decoys, pierce camouflage, operate in darkness and bad weather, do video surveillance, and detect enemy vehicles. They are smaller, lighter, cheaper, more fuel efficient, and easier to move; can avoid harm to humans; and… read more
InPhase Technologies, a spinoff of Lucent Technologies’ research arm Bell Labs, has introduced the first commercial holographic video recorder. Aimed at professional video editors, it holds 100GB of data on a single CD-sized disc as a series of 1.3MB holograms, enough for 20 full-length movies or 30 minutes of uncompressed high-resolution video.
The extended storage is due to the fact that each storage location can hold multiple holograms.
The U.S. Air Force is developing a body suit for pilots who fly remote-controlled aircraft such as the Predator. Using a system of electromagnets and magnets that apply pressure to the suit, it will give pilots feedback from the plane’s motions. The technology could also be used in the future for improved arcade games.
“Created under a U.S. Department of Defense contract by an MIT spinoff company called iRobot, Morticia is a military machine with a mission. Instead of carrying bombs, she carries eyes and ears, transmitting what she sees back over a wireless link. She is also a pioneer, showing us how robots are likely to be integrated into our jobs and our lives in the coming years.”
Morticia is a prototype of… read more
