By modifying the underlying network of cellulose fibers, etching off surface “fluff” and applying a thin chemical coating, Georgia Institute of Technology researchers have created a new type of paper that repels a wide variety of liquids — including water and oil.

The paper takes advantage of the “lotus effect” — used by leaves of the lotus plant — to repel liquids through the creation… read more

Advanced quantum computer to be developed

April 25, 2001

University of Wisconsin-Madison researchers plan to use silicon germanium quantum dots to create a quantum computer.

Under a U.S. Army Research Office $1.2 million grant, the team will combine advanced physics theory, silicon-germanium heterostructured materials, and low-temperature and high frequency measurements to build a semiconductor-based quantum gate or qubit.

Researchers predict the process could be scaled to make and link thousands of qubits, resulting in the first useful… read more

Advanced retinal implant developed

March 31, 2010

Advanced retinal implant

Bionic Vision Australia and University of New South Wales researchers have developed an advanced retinal implant to enable patients suffering from degenerative vision loss caused by retinitis pigmentosa and age-related macular degeneration to perceive points of light in the visual field that the brain can then reconstruct into an image.

The device consists of a miniature camera mounted on glasses that captures visual input, transforming it into… read more

Advanced Robotic Arm Controlled by Monkey’s Thoughts

June 4, 2010

Researchers at the University of Pittsburgh have taught a monkey to use its thoughts to control an advanced robotic arm with seven degrees of freedom and perform elaborate and precise maneuvers with it.

Sensors implanted in the hand and arm areas of its motor cortex send data to a computer that translates the patterns into commands that control the robotic arm.

Researchers hope to one day be able… read more

Advanced Solar Panels Coming to Market

September 17, 2009

Nanosolar's new, fully automated solar-panel manufacturing facility (Nanosolar)

Nanosolar has opened an automated facility for manufacturing its solar panels, and says power plants made using these panels could produce electricity at five to six cents per kilowatt hour — near the cost of electricity from coal and significantly less than most solar power, which costs about 18 to 22 cents per kilowatt hour.

The panels are made by printing a semiconductor material called CIGS (copper, indium, gallium,… read more

Advances in nanotechnology enable targeted drug delivery

Three research groups announced nanotechnology-based targeted drug-delivery systems Wednesday.

Researchers at Cedars-Sinai’s Maxine Dunitz Neurosurgical Institute have used a highly targeted approach to deliver multiple drugs chemically bonded to a transport vehicle. The objective is to bypass healthy cells, accumulate inside tumor cells, and attack molecular targets that enable cancer cells to grow and spread.

The drug transport is in an emerging class called… read more

Advances in Quantum Computing

December 4, 2001

Quantum computing borrows ideas from finance: a balanced portfolio of programs could mean a faster quantum computer.Strategies from the world of finance could help get the best out of quantum computers, say US researchers. The right portfolio of programs could solve a problem many times faster than a single strategem.

Quantum computers – purely hypothetical as yet – would be fast, but you could never be sure whether a… read more

A biped robot design being built by researchers at Oregon State University has the potential to reduce energy use while improving robotic locomotion.

Advances Offer Path to Shrink Computer Chips Again

August 31, 2010

Scientists at Rice University and Hewlett-Packard are reporting this week that they can overcome a fundamental barrier to the continued rapid miniaturization of computer memory by using memristors, or memory resistors, switches that retain information without a source of power.

In a development that could make the advanced form of secure communications known as quantum cryptography more practical, University of Michigan researchers have demonstrated a simpler, more efficient single-photon emitter that can be made using traditional semiconductor processing techniques.

Single-photon emitters release one particle of light, or photon, at a time, as opposed to devices like lasers that release a stream of them.

Single-photon… read more

Researchers have trained a monkey to feed itself by guiding a mechanical arm with its mind. It could be a big step forward for prosthetics.

Aerobic exercise boosts brain power in elderly

Prefrontal Cortex

Evidence for the importance of physical activity in keeping and potentially improving cognitive function throughout life was found in an open-access literature review in Psychonomic Bulletin & Review by Hayley Guiney and Liana Machado from the University of Otago, New Zealand.

  • Cognitive functions such as task switching, selective attention, and working memory appear to benefit from aerobic exercise. Studies in older adults reviewed

Aerobic exercise grows brain cells

January 21, 2010

Aerobic exercise stimulates the growth of new brain cells and improves the memory and ability to learn, neuroscientists from University of Cambridge and the US National Institute on Aging have found in experiments with mice.

Running mice grew an average of 6,000 new brain cells per cubic millimeter in the dentate gyrus part of the hippocampus.

The researchers speculate that the effect may be due to increased blood… read more
