New email-filtering software uses natural-language processing to scan e- mail messages and identify possible spam messages.

Saving the universe by restricting research

April 15, 2003

History’s worst technological catastrophes could kill millions or billions of people in this century, and to prevent them, society may need to consider restricting specific types of scientific research, says Sir Martin Rees, Britain’s astronomer royal, in the book, “Our Final Hour.”

His concerns include gray goo (nanobots out of control) and experiments that could create a black hole. “I think the odds are no better than 50-50 that… read more

A Voice Recognition Tool Frees Hands for Other Tasks

April 13, 2003

Voice-recognition developers have made enough progress in recent years to produce several low-priced options. The latest is the QPointer, which enables users to operate a PC without touching the mouse or even, in some models, the keyboard.

Intel, Nokia, Proxim, Others Launch WiMax

April 13, 2003

Intel, Nokia, Proxim, and a host of other companies have launched WiMax, a non-profit group formed to certify and promote the developing wireless broadband standard 802.16.

This technology will connect 802.11 hot-spots to the Internet and provide a wireless extension to cable and DSL for last-mile broadband access. 802.16 provides up to 31 miles of linear service area range without direct line of sight to a base station. The… read more

Metal muscles could power artificial limbs

April 11, 2003

Muscles made of platinum crystals could outperform their motor-and-gear-based counterparts for use in everything from replacement artificial limbs to robots operating in war and space exploration.

Pushing the Speed Limit: For Researchers, the Internet Just Got Faster

April 10, 2003

Caltech researchers have developed a new data communications protocol capable of 8.6 gigabits per second data transfer across 2,845 miles.

Unlike the single-path TCP protocol, the Fast Active queue management Scalable Transmission Control Protocol, or FAST, uses 10 parallel routes.

In 24-Hour News Times, Real-Time Translation

April 10, 2003

Virage Inc. has recently supplied several unnamed United States intelligence agencies with a system that will provide real-time voice recognition and English translation of foreign-language news broadcasts.

Computers that watch while you work

April 10, 2003

Canadian researchers have designed a computer that pays attention to the person using it. An eye-contact sensor allows the computer to determine whether the user is present and whether he or she is looking at the screen so the computer can determine when and whether to contact them.

Are we doomed yet?

April 9, 2003

The computer-networked, digital world poses enormous threats to humanity that no government, no matter how totalitarian, can stop. A fully open society is our best chance for survival.

New rules for a society of wizards are being proposed and implemented every day. In recent times, a leading technologist has called for us to reconsider “the open, unrestrained pursuit of knowledge,” a federal judge has ordered an injunction against hyperlinking… read more

Is There Life After Silicon Valley’s Fast Lane?

April 9, 2003

Some experts warn that Moore’s Law may soon reach its theoretical limits, with dire consequences for the technology industry’s economic engine.

Others believe the popular conception of Moore’s Law had become outdated.

Measuring the Risks of Nanotechnology

April 8, 2003

Do breakthroughs in nanotechnology present unique health and environmental dangers that need to be studied?

New Fusion Method Offers Hope of New Energy Source

April 8, 2003

Sandia National Laboratories reported today that they had achieved thermonuclear fusion, in essence detonating a tiny hydrogen bomb. This might offer an alternative way of generating electricity by harnessing fusion, which combines hydrogen atoms into helium, producing bountiful energy as a byproduct without long-lived radioactive waste.

Discovery of electrostatic spin challenges century-old theory

April 7, 2003

University of California, Riverside researchers have identified a new physical phenomenon, electrostatic rotation, that, in the absence of friction, leads to spin. The phenomenon will likely impact atomic physics, chemistry and nanotechnology.

Because the electric force is one of the fundamental forces of nature, this leap forward in understanding may help reveal how the smallest building blocks in nature react to form solids, liquids and gases that constitute the… read more

Inventor Imagines Future Phones

April 7, 2003

Cell-phone inventor Martin Cooper visualizes a miniaturized cell phone that fits behind his ear, automatically dials out when he thinks about calling someone, and notifies him of incoming calls with a tickle instead of a ring.

Cooper believes the next big advancement in the wireless industry will be ubiquitous, wide-area, high-speed access to the Internet.
