Realizing Lithium-Battery Potential

December 3, 2008
These silicon particles can absorb over six times more lithium ions by weight than graphite can, making them a candidate for creating electrodes for supercharged lithium batteries. (Jaephil Cho, Hanyang University)

Hanyang University researchers have developed a nanoporous silicon electrode that could at least double the charge capacity of a lithium battery–essentially doubling the range of an electric vehicle.

How to Make a White Hole in Your Kitchen Sink

October 18, 2010

(G. Jannes et al.)

Scientists have shown experimentally that liquid flowing from a tap embodies the same physics as the time-reversed equivalent of black holes.

When a stream of tap water hits the flat surface of the sink, it spreads out into a thin disc bounded by a raised lip, called the hydraulic jump. Recently, physicists have suggested that, if the water waves inside the disc move faster than the waves outside, the… read more

Human intelligence determined by volume and location of gray matter tissue in brain

July 21, 2004

General human intelligence appears to be based on the volume of gray matter tissue in certain regions of the brain, UC Irvine College of Medicine researchers have found in the most comprehensive structural brain-scan study of intelligence to date.

Previous research had shown that larger brains are weakly related to higher IQ, but this study is the first to demonstrate that gray matter in specific regions in… read more

Molecular holograms are coming into focus

June 11, 2007

3D images of individual molecules may soon be possible thanks to a breakthrough in holography by Swiss scientists.

The technique would be useful to biologists interested in how the shapes of proteins and other components of life relate to their function.

The technique uses a computer program that reduces superimposed twin images, which signficantly reduce resolution at x-ray wavelengths.

Brain’s white matter — More ‘talkative’ than once thought

May 7, 2007

Johns Hopkins scientists have discovered to their surprise that nerves in the mammalian brain’s white matter do more than just ferry information between different brain regions, but in fact process information the way gray matter cells do.

The Newspaper Industry Is Saved! (Or Not)

December 9, 2008
(Flexible Display Center at Arizona State University)

Hewlett-Packard and Arizona State University have announced a prototype computer display made of plastic, but is paper-like, allowing images to appear on the displays without distortion despite rolling and bending.

It may allow electronic displays to become easily portable and more energy-efficient.

Robotic Limbs that Plug into the Brain

October 27, 2010

A brain-controlled prosthetic arm, under development at the Applied Physics Lab at Johns Hopkins University with funding from DARPA, may allow amputees to make much more sophisticated movements.  (DARPA/JHUAPL/HDT Engineering Services)

A new generation of much more sophisticated and lifelike prosthetic arms, sponsored by DARPA, may be available within the next five to 10 years. Two different prototypes that move with the dexterity of a natural limb and can theoretically be controlled just as intuitively — with electrical signals recorded directly from the brain — are now beginning human tests.

The new designs have about 20 degrees of independent motion,… read more

What Dreams Are Made Of

August 3, 2004

New technology is helping brain scientists unravel the mysteries of the night. Their work could show us all how to make the most of our time in bed.

The long-range goal of dream research is a comprehensive explanation of the connections between sleeping and waking, a multidimensional picture of consciousness and thought 24 hours a day.

Can cyborg moths bring down terrorists?

June 19, 2007

The Defense Advanced Research Projects Agency (DARPA) is growing moths around a computer chip implanted when the creature was still in the cocoon, meaning that the moth’s entire nervous system can be controlled remotely.

Rodney Brooks, director of the Computer Science and Artificial Intelligence lab at MIT, which is involved with the research, said that the MEMS-based were one of a number of technologies soon to be deployed in… read more

Wake-up call to genes may lead to cure for baldness

May 20, 2007

Scientists have found a way to regenerate hair follicles that may lead to a cure for baldness, by reawakening genes once active only in developing embryos.

Forecast 2030: Oil Use Flat, Hybrids Ascendant

December 18, 2008

The Annual Energy Outlook projecting United States energy trends through 2030 foresees flat demand for oil, a shrinking need for imports, and enormous expansion of the percentage of light vehicles with hybrid fuel-electric propulsion.

A team led by University of Arizona (UA) optical sciences professor Nasser Peyghambarian has developed a new type of “holographic telepresence” that allows remote projection of a three-dimensional, moving image without the need for special eyewear such as 3D glasses or other auxiliary devices.

The technology is likely to take applications ranging from telemedicine, advertising, updatable 3D maps and entertainment to a new level.

Breakthrough Nanotechnology Will Bring 100 Terabyte 3.5-inch Digital Data Storage Disks

August 16, 2004

100 terabytes of data on a 3.5-inch disk may be possible with a new technique for creating an “Atomic Holographic DVR” disc drive within five years, priced at $570 to $750 with the replacement discs for $45.

Cell-transistor interface clears biolectronics hurdle

June 28, 2007

Researchers at the Max Planck Institute have developed a cell-transistor interface that they believe will usher in a new era of bioelectronics, allowing cells to be manipulated and studied without destroying them in the process.

In a demonstration, the chip was used to test the effect of new drugs on the living cells.
