Carbon nanotube fibers invented at Rice Univ. may provide a way to communicate directly with the brain. The fibers have proven superior to metal electrodes for deep brain stimulation and to read signals from a neuronal network. Because they provide a two-way connection, they show promise for treating patients with neurological disorders while monitoring the real-time response of neural circuits in areas that control movement and mood.
The sweet taste and smell of antifreeze tempts children and animals to drink the poisonous substance, resulting in thousands of accidental poisonings in the U.S. every year. But today researchers will describe a new, nontoxic product based on a common food additive that could address this health issue and help the environment at the same time.
Los Alamos National Laboratory mechanical and thermal engineering researchers’ efforts to solve the complex problem of how ocean currents affect the infrastructure of floating oilrigs and their computational fluid dynamics numerical simulations received recognition from ANSYS Inc.
Rechargeable lithium-ion batteries are commonly found in portable electronics such as cell phones and notebook PCs. They’re also gaining popularity in electric vehicles, where their compact, lightweight build and high-energy storage potential offers a more efficient and environmentally safe alternative to nickel metal hydride and lead-acid batteries traditionally used in vehicles.
Researchers at Carnegie Mellon Univ. (CMU) who develop snake-like robots have picked up a few tricks from real sidewinder rattlesnakes on how to make rapid and even sharp turns with their undulating, modular device. Working with colleagues at the Georgia Institute of Technology and Zoo Atlanta, they have analyzed the motions of sidewinders and tested their observations on CMU’s snake robots.
Virtual reality games often cause simulator sickness, but new research findings point to a potential strategy to ease the affliction. Various physiological systems govern the onset of simulator sickness: a person's overall sense of touch and position, or the somatosensory system; liquid-filled tubes in the ear called the vestibular system; and the oculumotor system, or muscles that control eye movements.
Researchers at Massachusetts Institute of Technology and Stanford Univ. have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun’s energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say.
Engineers have taken a leaf out of nature's book by equipping an artificial hand with muscles made from shape-memory wire. The new technology enables the fabrication of flexible and lightweight robot hands for industrial applications and novel prosthetic devices.
Scientists have observed the point at which classical and quantum behavior converge. Using a fiber-based nonlinear process, the researchers were able to observe how, and under what conditions, "classical" physical behavior emerges from the quantum world.
One infrared scan can give pathologists a window into the structures and molecules inside tissues and cells, enabling fast and broad diagnostic assessments, thanks to an imaging technique developed by University of Illinois researchers and clinical partners.
Researchers have made an experimental breakthrough in explaining a rare property of an exotic magnetic material, potentially opening a path to a host of new technologies.
As nanotechnology makes possible a world of machines too tiny to see, researchers are finding ways to combine living organisms with nonliving machinery to solve a variety of problems. Like other first-generation bio-robots, the new nanobot engineered at the University of Illinois at Chicago is a far cry from Robocop. It's a robotic germ.
In a study, a team of scientists at the University of Wisconsin-Madison has developed a new, faster approach to analyze all the data that will come out of the new, super-advanced Square Kilometer Array (SKA), a radio telescope planned for Africa and Australia that will have an unprecedented ability to deliver data on the location and properties of stars, galaxies and giant clouds of hydrogen gas.
Until now, doctors have been able to measure bone loss — a process that happens slowly, over time — but haven’t had the means for gauging actual bone strength. That has changed thanks to a new handheld instrument. Called the OsteoProbe, the device uses reference point indentation (RPI) to measure mechanical properties of bone at the tissue level.
New research conducted at the University of Kansas Medical Center has found a correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione in the brain in older, healthy adults.
