‘Smart’ Silicon Dust Could Help Screen for Chemical Weapons

September 13, 2002

Scientists report the development of dust-size “smart” silicon crystals that could be used to detect chemical and biological agents from a distance, using a laser light source.

Intel pushing to develop 1-billion transistor processor

September 13, 2002

Intel Corp. has announced it is developing a 1-billion-transistor chip that will integrate logic, graphics and security. It is part of Intel’s “convergence” push to accelerate the development of computing and communications.

Nanowire or nanotube? Intel looks ahead

September 11, 2002

Intel is working with Harvard and other universities on silicon nanowires and carbon nanotubes. After 2010, one of these technologies could begin to replace standard transistors and over time become the building block of chips.

Intel is also experimenting with atomic layer deposition, which lets manufacturers make chips by piling single layers of atoms on top of each other.

Single atom memory device stores data

September 11, 2002

A workable atomic memory that uses individual atoms to store information has been developed by physicists, representing a density equivalent to 250 terabits of data per square inch.

In the experiment, each single silicon atom was added or removed from a block of twenty others using a scanning tunnelling microscope.

According to Tom Theis, director of physical sciences at IBM’s T.J. Watson Research Center, it may one day… read more

Nanotech’s grand challenge: energy self-sufficiency, says von Ehr

September 11, 2002

“Nanotechnology needs a ‘grand challenge’ project, and energy self-sufficiency is one that would pay huge benefits to both the USA and the world,” says James R. von Ehr II, President & CEO of Zyvex Corp.

He presented this idea at the recent White House Economic Forum, which brought together leaders from various sectors to discuss the fundamentals of the economy and the President’s agenda to increase economic growth for… read more

AMD fabricates double-gate transistor for 10-nm designs

September 11, 2002

Advanced Micro Devices Inc. here today announced it has fabricated the world’s smallest double-gate transistors, measuring 10 nanometers.

Cleaner Living Through Nanotech

September 10, 2002

Scientists see nanotechnology as the the key to solving some current environmental ills.

Tricks of the light promise record data speeds

September 9, 2002

Researchers have shown that the bandwidth of existing fiber optic cables can be increased from 10 gigabits/second to 2 terabits/per second, using new techniques, including a subcarrier, multiple wavelengths, and multiple polarizations.

Kurzweil receives honorary doctorate at Landmark College

September 6, 2002

Dr. Ray Kurzweil received an honorary doctorate degree from Landmark College of Putney, Vermont today. Landmark College is the nation’s premier college for high-potential students with learning disabilities and attention deficit hyperactivity disorder. “Ray Kurzweil’s impact on students with learning disabilities has been immeasurable,” noted Landmark president Lynda J. Katz, Ph.D. “The extraordinary strides some of our students make at Landmark College would simply not be possible were it not… read more

A Theory of Evolution, for Robots

September 6, 2002

Scientists have designed a winged robot capable of learning flight techniques automatically with genetic algorithms. Its small motors allow it to manipulate its meter-long, balsa-wood wings in different directions. A computer program feeds the robot random instructions, which let it develop the concept of liftoff on its own.

Musical approach helps programmers catch bugs

September 6, 2002

Researchers have developed a system that automatically converts computer program code written in Pascal into simple “music” to make it easier for programmers to detect bugs from sequences of notes.

Parents look to microchip children

September 5, 2002

Worried UK parents are asking to have tracking microchips implanted into their children following the murders of two 10-year-old girls, says scientist Kevin Warwick, who has implanted a chip in his arm that is connected to a computer in an ongoing experiment.

The operation would involve implanting a small transmitter about one inch long into the child’s arm or stomach, Warwick said. Tracking options include using a mobile phone… read more

Dinosaur ancestor’s vision possibly nocturnal

September 4, 2002

Scientists at Rockefeller University have reconstructed the light-sensing rhodopsin protein from the ancestors of dinosaurs. It suggests that dinosaurs may have been well-adapted to seeing in the dark. Belinda S.W. Chang, Ph.D., first author and research assistant professor at Rockefeller, used existing databases and sophisticated statistical methods to infer the most likely DNA sequences that the ancestral archosaur would have had for its rhodopsin.

“From the databases, we pulled… read more

They Weren’t Meant to Be Games

September 4, 2002

Video games have rocketed past movies in mass appeal, driven by powerful technologies that have transformed games into fully interactive worlds.

A high-quality video game now can surpass traditional action movies in terms of realism, usability, return visits, interactivity and subtlety, thanks to sophisticated computer graphics, improved sound effects, and use of artificial intelligence for character portrayal and movement.

Radio emerges from the electronic soup

September 2, 2002

A self-organising electronic circuit with evolutionary computer program to “breed” an oscillator circuit has stunned engineers by turning itself into a radio receiver. Researchers discovered that the evolving circuit had used the computer’s circuit board itself as an antenna, picking up a signal from a nearby computer and delivering it as an output.
