IBM nanotubes may enable molecular-scale chips

April 27, 2001

IBM researchers have developed a bulk process for producing nanotube transistors only 10 atoms wide, or 500 times smaller that current silicon transistors.

“We believe IBM has now passed a major milestone on the road toward molecular-scale chips,” said Thomas Theis, director of physical sciences at IBM’s Thomas J. Watson Research Center here. “Our researcher’s study [to be published Friday (April 27)] in Science magazine proves that… read more

Intel getting into micro-machines

April 26, 2001

Micro-refrigerators, mini-tweezers for microbiologists, wireless antenna controllers, new-drug testing systems, and blood-screening sensors for lab tests are the types of products Intel could start producing with its move into microelectromechanical systems (MEMS).

MEMS systems are essentially semiconductors with mechanical parts that both harvest data and issue commands based on the data.

Retinal Displays Add Data Layer

April 26, 2001

Computer displays that project images directly onto the viewer’s retina, Terminator-style, are expected to be available this fall.

Microvision Inc., based in Bothell, Wash., plans to market Nomad, a single-color version of that kind of display. A tiny laser projector inside a head-mounted display beams light through the pupil and onto the nerve cells in the retina at 800 x 600 pixels resolution.

Uses include data for surgeons… read more

Kurzweil awarded MIT’s Lemelson Prize for Invention and Innovation

April 25, 2001

Futurist Ray Kurzweil was awarded MIT’s annual $500,000 Lemelson Prize for Invention and Innovation today at a ceremony at the Smithsonian Museum of Natural History in Washington, D.C.

Kurzweil was recognized for “the breadth and scope of his inventive work and for his commitment to enhancing the quality of life for people with disabilities through technology,” according to a statement by the Lemelson-MIT Program.

Kurzweil is credited with… read more

Advanced quantum computer to be developed

April 25, 2001

University of Wisconsin-Madison researchers plan to use silicon germanium quantum dots to create a quantum computer.

Under a U.S. Army Research Office $1.2 million grant, the team will combine advanced physics theory, silicon-germanium heterostructured materials, and low-temperature and high frequency measurements to build a semiconductor-based quantum gate or qubit.

Researchers predict the process could be scaled to make and link thousands of qubits, resulting in the first useful… read more

Merkle to teach half-day nanotech course at UC Berkeley

Hackers in China and US wage cyber war

April 25, 2001

American hackers are urging each other to break into websites hosted in China, and claim that US hackers have already penetrated hundreds of Chinese websites in the “China-Killer” blitz.

Chinese hackers are vowing to retaliate with a week-long attack on US-based websites and computer networks, starting May 1.

Big Blue’s Big Brother Lab

April 24, 2001

The IBM Almaden Research Center in San Jose, California is developing advanced haman-interface computing devices, including:

- A Terminator-style camera with gaze-tracking technology to identify the face and display the name of the person on a sunglasses-mounted display. It could also perform automated language translation of viewed text.

- An electronic communal bulletin board that gives everyone whose personal information is in a database access to their desktop… read more

Chameleon-nanostructure sensors developed

April 23, 2001

Intelligent nanostructures that report on their environment by changing color from blue to fluorescent red under mechanical, chemical, or thermal stress have been created by researchers at Sandia National Laboratories and the University of New Mexico.

The self-assembling structures, reported in the April 19 Nature, may lower costs by reducing the need for expensive manufactured devices like stress detectors, chemical analyzers, and thermometers, according the Sandia researchers.

Freezing Time: Plans for a Giant Cryonics Facility Are Heating Up

April 23, 2001

Timeship will be a six-acre, $180 million “Noah’s Ark” for 10,000 people and plants and animals, as well as stem cells of near-extinct species and human organs for transplant.

The project’s architect, Stephen Valentine, was commissioned by life-extension groups, including the Stasis Foundation. He hopes to break ground by 2002, with systems for energy self-reliance in a secure facility located possibly in the American Southwest or Florida.

Plans… read more

Rand report examines technology trends

April 19, 2001

A Rand Corporation “foresight” report on “The Global Technology Revolution: Bio/Nano/Materials Trends and Their Synergies with Information Technology by 2015″ examines the potential effects of several technological trends over the next 15 years, influenced by advances in biotechnology, nanotechnology, materials technology, and information technology.

The full report is available online.

The Programmable Pill

April 18, 2001

“Smart” methods of delivering drugs to the body—-based on micro- and nanotechnology—-could reduce side effects, make better use of existing drugs and open the door to entire classes of new treatments.

For example, Tejal Desai, assistant professor of bioengineering at the University of Illinois at Chicago and iMedd of Ohio are building 150-microns-wide silicon particles. On one side, up to 20 drug-containing reservoirs are etched, each sealed with a… read more

DNA is model for self-assembling nanostructures

April 18, 2001

Purdue University researchers are using the same principle that makes DNA strands link together to create tiny structures that may someday be used to develop nanostructures with specific dimensions and chemical properties.

“We have perfect control over every part of the system,” says Hicham Fenniri, an assistant professor of chemistry who directed the effort. “We not only dictate how the molecule behaves, but we also can control… read more

Could tutoring a computer be the way to develop machines that talk back?

April 18, 2001

HAL, a software program designed by Dutch-based firm Artificial Intelligence to learn language, currently passes for a 18 month old child and has a 50 or 60 word vocabulary.

By the end of 2003, AI expects to have a version of HAL capable of talking like a three-year-old and by 2005 hopes it will have the conversational skills of an adult.

HAL uses simple learning algorithms based on… read more

Law Professor Sees Hazard in Personalized News

April 13, 2001

With the rise of personalized Internet news, the democratizing effects of streets and general interest publications are at risk of being overwhelmed by passive consumers who live in Internet-filtered information cocoons, says Cass R. Sunstein, a professor at the University of Chicago Law School in Republic.com, a new book.
