Small Times launches micro-, nano-oriented website

April 30, 2001 is a new web site “devoted entirely to the fast-growing industry that includes MEMS, microsystems and nanotechnologies.”

The publisher will also launch Small Times Magazine in September 2001.

Time Capsule’s Digital Divide

April 30, 2001

A time capsule set to open in the year 3000 is preserving today’s culture the old-fashioned way: analog.

Documents from the late 20th century have been printed on acid-free paper and sealed in steel boxes in The New York Times Capsule located at the American Museum of Natural History.

“Digital formats, by and large, are not as permanent,” said Stephen Mihm, the project manager for the capsule. “Most… read more

Search Engines Ready to Learn

April 28, 2001

The next generation of web search tools uses machine-learning algorithms to classify and extract information.

These tools use “entity extraction,” automatically extracting specific types of entities, such as dates, cities, countries, person or company names, and storing collections of interrelated entities in database records for structured information access. WhizBang Labs is a leader in the area.

The next step: adding natural-language querying.

The scary side of the digital future

April 28, 2001

Maybe we’ve finally created a global system based on technology that’s too complex for human beings to understand or control, says Thomas Homer-Dixon, author of The Ingenuity Gap.

Homer-Dixon describes genetic programming, in which code is set up to evolve quickly and essentially write itself. But we have to create ever more complex machines to control ever more complex systems, so when the machines get too complex, do we… read more

Behind BlueEyes

April 27, 2001

A number of large retailers have implemented surveillance systems that record and interpret customer eye movement and facial expression, using software from Almaden’s BlueEyes research project.

BlueEyes works by tracking pupil, eyebrow and mouth movement, using a camera and two infrared light sources placed inside the product display. One light source is aligned with the camera’s focus; the other is slightly off axis. When the eye looks into the… read more

Science’s Elusive Realm: Life’s Little Mysteries

April 27, 2001

The mysterious realm of the mesoscale, a region between molecules and living cells, where proteins fold, charged ions move through cell membranes and messenger molecules read DNA instructions in the cell nucleus, has remained largely inaccessible.

Now work has begun under the auspices of the Institute for Complex Adaptive Matter (ICAM), a new and independent unit of the Los Alamos National Laboratory and the University of California at Berkeley,… read more

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

April 25, 2001

Leading nanotechnology researcher Ralph Merkle will conduct a UC Berkeley Extension course designed for the public, “Nanotechnology: Basic Concepts and Potential Applications,” on Saturday, May 5, 1-5 p.m., in Dwinelle Hall on the UC Berkeley campus in Berkeley. The fee is $20.

To register, call 510/642-4111 or register online.

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.

The… read more
