Semiconducting Nanotubes Are ‘Holy Grail’ for Electronic Applications

January 22, 2009

Duke University chemists have created exclusively semiconducting versions of single-walled carbon nanotubes for use in manufacturing reliable electronic nanocircuits.

In addition to being tiny, these nanotubes offer reduced heat output and operation a higher frequencies, compared to current materials used to make miniaturized electronic components such as transistors.

Putting electronics in a spin

August 8, 2007

Spintronics could render today’s supercomputers obsolete.

New Tools to Help Patients Reclaim Damaged Senses

November 23, 2004

New technology allows one set of sensory information to substitute for another in the brain.

Using novel electronic aids, vision can be represented on the skin, tongue or through the ears. If the sense of touch is gone from one part of the body, it can be routed to an area where touch sensations are intact. Pilots confused by foggy conditions, in which the horizon disappears, can right their… read more

How Ray Kurzweil Keeps Changing the World

May 2, 2001

By 2010, all communications barriers facing people with disabilities will have disappeared, says inventor Ray Kurzweil, “dreamer, genius, and humanitarian.” He predicts:

- A handheld text-to-speech device for blind and visually impaired individuals (Kurzweil Educational Systems is currently developing).

- A speaker-independent small “listening machine” to convert speech into type, built into eyeglasses and projecting the text of spoken conversations onto the lenses — even directly onto the… read more

I’m a skeptic now, says ex-NASA climate boss

January 29, 2009

Dr John Theon, the retired scientist formerly in charge of key NASA climate programs who supervised James Hansen — the activist-scientist who helped give the manmade global warming hypothesis centre prominent media attention — has come out as a skeptic about man-made global warming.

“My own belief concerning anthropogenic climate change is that the models do not realistically simulate the climate system because there are many very important sub-grid… read more

Wozniak’s New Goal is Efficient Housing

August 15, 2007

Steve Wozniak is developing techniques to build homes with the least energy usage and pollution (using, for example, ram-dirt) and the least energy to operate.

When technology gets personal

December 7, 2004

In 2020 phones will be printed directly on to wrists, or other parts of the body, part of what’s known as a “pervasive ambient world” where “chips are everywhere” says Ian Pearson, BT’s (British Telecom’s) resident futurologist.

Researchers have developed computers and sensors worn in clothing. MP3 jackets, based on the idea that electrically conductive fabric can connect to keyboards sewn into sleeves, have already appeared in stores.… read more

Mimicking Nature

May 22, 2001

A computer program that mimics the barn owl’s sonic processing in locating prey has been developed by John Harris, a University of Florida engineering professor. Uses include tracking of speaker location for videoconferencing.

Managing Energy with Swarm Logic

February 4, 2009

REGEN Energy has has come up with a way to reduce energy use by mimicking the self-organizing behavior of bees.

Their wireless controller functions as a smart power switch. Once several controllers have been activated, they detect each other using a networking standard called ZigBee and begin negotiating the best times to turn equipment on and off. The devices learn the power cycles of each appliance and reconfigure them… read more

Talk to the Phone

Vlingo, a startup in Cambridge, MA, is coming to market with a ­simple user interface that provides speech recognition across mobile-phone applications.

How phase change materials could combine RAM’s speed + flash’s non-volatility and capacity

Could PCM be the long-sought “universal memory” --- combining both non-volatility,high switching speeds, and scalability (ability to store large amounts of data)?

University of Pennsylvania researchers have found out how memory devices switch between phases (o’s and1′s), which could help engineers make memory storage devices faster, non-volatile, and high-capacity.
Background

“For many years there has been a push to find memory storage that is at once scalable, non-volatile, and fast,” Agarwal said. “Phase change materials could meet all of those criteria, but the problem is that we don’t know much… read more

Nanodiamond technology could yield better flat panel displays

December 17, 2004

A research collaboration between the University of Bristol and Advance Nanotech to develop new display technology made from Bristol’s nanodiamond technology could lead to cheaper and more power efficient flat panel displays for use in wide screen digital TVs and other applications.

Genetic mapping technique speeds search for genetic illness

June 11, 2001

A new genetic mapping technique could shorten from months to weeks the time needed to identify chromosomal “hot spots” associated with particular diseases, reports the June 8 Science magazine.

The algorithm swiftly finds quantitative trait loci (QTL) chromosomal regions that probably contain genes that contribute to a particular trait.

Asteroid bound for Earth! Warn your grandchildren

February 10, 2009

New calculations show a 1 in 1400 chance that the gigantic Asteroid 1999 RQ36, with an estimated diameter of 560 meters, will strike Earth between 2169 and 2199, according to Andrea Milani of the University of Pisa in Italy and colleagues.

In the Genome Race, the Sequel Is Personal

September 4, 2007

Biologist J. Craig Venter has decoded a new, higher-quality version of the human genome, using his own genome.

Called a full, or diploid genome, it consists of the DNA in both sets of chromosomes, one from each parent, and it is the normal genome possessed by almost all the body’s cells. It makes clear that the variation in the genetic programming carried by an individual is much greater than… read more
