Stretchable silicon could be next wave in electronics

December 16, 2005

University of Illinois at Urbana-Champaign researchers have developed a fully stretchable form of single-crystal silicon with micron-sized, wave-like geometries that can be used to build high-performance electronic devices on rubber substrates.

Functional, stretchable and bendable electronics could be used in applications such as sensors and drive electronics for integration into artificial muscles or biological tissues, structural monitors wrapped around aircraft wings, and conformable skins for integrated robotic sensors, said… read more

UCLA develops scalable method of fabricating high-speed graphene transistors

June 20, 2011

Graphene Transistors

Researchers at the Nanoelectronics Research Facility and the Center for High Frequency Electronics at the University of California, Los Angeles have developed a scalable approach to fabricating high-speed graphene transistors.

This represents a significant advance toward graphene-based, radio-frequency circuits that could be used in a variety of devices, including radios, computers, and mobile phones. The technology might also be used in wireless communication, imaging, and… read more

Exclusive Intel Product Roadmap Details

February 28, 2003

Intel’s entire roadmap for the next few years will be revealed on Ziff Davis’ ExtremeTech site.

Your Cyborg Eye Will Talk to You

September 1, 2009

Circuits embedded into contact lenses to display information to the wearer are being developed by University of Washington researchers, with future plans to superimpose computer-generated high-resolution color graphics.

Tumor growth block hopes raised

March 17, 2008

Harvard Medical School and Beth Israel Deaconess Medical Center researchers have identified an enzyme–pyruvate kinase enzyme in its PKM2 form–that enables cancer cells to consume the huge quantities of glucose they need to fuel uncontrolled growth.

Commentary: Living forever

December 29, 2005

Ray Kurzweil “takes human evolution far beyond today’s most optimistic forecasts in … arguably the most blogged-about book of 2005, a 640-page blockbuster: ‘The Singularity Is Near.’”

“These hold that anyone born today will live to be 130 and productive to 110, and those born in the 22nd century will live to 250. The glass-half-full-and-filling geomancers of the human genome research world can perceive ‘immortality’ in the 23rd century.… read more

Mayo Clinic developing artificial pancreas to ease diabetes burden

June 24, 2011

Mayo Clinic endocrinologists are developing an artificial pancreas that will deliver insulin automatically and with an individualized precision never before possible.

The “Closed Loop System” under development includes a blood sugar monitor, an automatic insulin pump, a set of activity monitors that attach to the body, and a central processing unit.

In related research, they found that diabetics who engaged in low-grade physical activity… read more

Face-Recognition Technology Improves

March 14, 2003

Facial recognition technology has improved substantially since 2000, according to a federal government report. The best facial recognition systems can now correctly verify that a person in a photograph or video image is the same person whose picture is stored in a database 90 percent of the time, with one percent false positives. Performance has also been enhanced by improving technology to rotate images taken at an angle.

Hydrogen Storage Gets New Hope

September 8, 2009

A new method for recycling ammonia borane hydrogen-releasing fuel materials that could open the door to economically viable hydrogen-based vehicles has been developed by Los Alamos National Laboratory and University of Alabama researchers.

Cheap, Efficient Thermoelectrics

March 20, 2008
Random crystal lattices interrupt the flow of heat

MIT and Boston College researchers have developed an inexpensive, simple nanocomposite-based technique for achieving a 40 percent increase in the efficiency of a common thermoelectric material, making possible solar panels and car exhaust pipes that use waste heat for electrical power.

Digging for data that can change our world

January 10, 2006

Scientific research is being added to at an alarming rate, so it’s not surprising that academics seeking data to support a new hypothesis are getting swamped with information overload.

The U.K. government’s response has been to set up the National Centre for Text Mining, the world’s first center devoted to developing AI-based tools that can systematically analyze multiple research papers, abstracts and other documents, and then swiftly… read more

New light on how the retina sees

July 4, 2011

Photons Chromophores

Syracuse University researchers have shed new light on how the vision process is initiated: by the redistribution of electrons on chromophores (light-absorbing substances in retinal photoreceptor molecules).

This occurs during the first few femtoseconds (one-quadrillionth of a second) after light enters the eye, they found. Their experiments showed that when a chromophore absorbs a photon of light, electrons move from the chromophore’s “free” end to… read more

How Antispam Software Works

March 31, 2003

Smarter filtering techniques — from rules-based analysis to artificial intelligence — promises to eradicate junk mail.

Bayesian filtering, the most promising new technique, learns and relearns how to spot spam by scanning the mail you’ve read and the mail you’ve rejected. It filters out more than 99 percent of unwanted messages.

The Top 25 subject-line words and symbols: Fwd, Free, Get, FREE, $, !, SPAM, You, Your, Norton,… read more

Pursuing a Battery So Electric Vehicles Can Go the Extra Miles

September 15, 2009

A future-generation lithium-air battery might be the much sought after power source for electric vehicles with ranges that match gasoline powered cars of today if safety and cost issues are overcome, IBM scientists suggest.

Current-technology lithium-ion batteries have the potential to deliver about 585 watt-hours of electricity per kilogram; lithium-air batteries might reach targets well above 5,000 watt-hours.

Is Graphene the New Silicon?

March 28, 2008

University of Maryland physicists have found that graphene conducts electricity at room temperature with less intrinsic resistance than any other known material.

Graphene, a new material that combines aspects of semiconductors and metals, is one of the materials being considered as a potential replacement for silicon for future computing. The very high mobility of graphene would allow for transistors that must switch extremely fast.

The low resistivity and… read more
