Microsoft is seeking patents on a method of controlling computers using electromyography (EMG) — a system that translates electrical activity from muscles into instructions for the computer, including a completely wearable system of sensors on the head, chest, arm and leg.

How neurons make sense of our senses

November 22, 2011

Moving straight ahead

Scientists at the University of Rochester, Washington University in St. Louis, and Baylor College of Medicine have unraveled how the brain manages to process the complex, rapidly changing, and often conflicting sensory signals to make sense of our world.

The answer lies in a simple computation performed by single nerve cells: a weighted average. Neurons have to apply the correct weights… read more

Amyloids Have Have Potential as a Nanomaterials

May 29, 2008

Amyloids (found in tissues and linked to a number of diseases) have potential as nanomaterials because of their self-assembly and synthetic-polymer properties, according to University of Tel Aviv scientists Ehud Gazit and Izhack Cherny.

For example, they can be used to produce a conducting nanoscale coaxial cable by filling amyloid nanotubes with sliver and externally coating them with gold, and for encapsulation and controlled release of drugs.

Program detects tiny differences in images

August 13, 2003

Scientists at the U.S. Department of Energy’s Idaho National Engineering and Environmental Laboratory have developed a program that detects slight differences between digital images that signal early stages of disease.

The program aligns images, to within a fraction of a pixel, from hand-held or otherwise imprecise cameras. The alignment compensates for differences in camera angle, height, zoom or other distractions that previously confounded comparisons. There are also a variety… read more

A slime mold colony was able to create an efficient real inter-city road network for the UK, mimicking the actual road network, specialists in unconventional computing at the University of the West of England have found.

Neurons illuminate as they fire, may open new ways to trace brain signals

December 5, 2011

Guiding lights

In a scientific first that could shed light on how signals travel in the brain and on the effects of learning on neural pathways, Harvard scientists have created genetically altered neurons that light up across a cell as they fire, eliminating the need to insert electrodes in each neuron.

The work may also lead to speedier drug development.

Deriving the Properties of the Universe

January 18, 2010

The properties of the Universe can be derived by thinking about the origin of complexity, says a new theory by University of California, Berkeley and Stanford University physicists.

But, just like the anthropic principle, it also has the scent of circular reasoning about it: the universe is the way it is because if it were different, the complexity necessary to observe it wouldn’t be here to see it.

Researchers create a broadband light amplifier on a chip

July 10, 2006

Cornell researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips.

The amplifier uses a phenomenon known as four-wave mixing, in which a signal to be amplified is “pumped” by another light source inside a very narrow waveguide. The waveguide is a channel only 300 x 550 nanometers (nm = a billionth of a meter, about the length… read more

Researchers Design Band-Aid-Size Tactile Display

(Ig Mo Koo, et al.)

Researchers from Sungkyunkwan University in Korea and the University of Nevada have developed a flexible tactile display that can wrap around the fingertip, palm, or arm.

The key material in the display is an electroactive polymer that can stimulate the skin. It consists of eight layers of dielectric elastomer actuator films sprayed with electrodes in a specific pattern.

The soft display might provide a means of… read more
