Speeding up genome sequencing

November 25, 2003

The BioMEMS 768 Sequencer can sequence the entire human genome in only one year, processing up to 7 million DNA letters a day, about seven times faster than its nearest rival. It will be tested at Whitehead Institute this fall.

The technology eventually will help scientists quickly determine the exact genetic sequence of the DNA of many different organisms, and could lead to faster forensic analysis of DNA gathered… read more

Robo-receptionist clocks on

November 25, 2003

Inkha (“interactive neurotic King’s head assembly”), an android receptionist, will offer directions and events information to visitors at King’s College London starting next week.

Driven by nine motors and a small laptop computer and equipped with hidden cameras and infrared sensors to detect movement and color plus a touch screen, Inkha leans towards interesting people and shies away from sudden movements. She chats when people are around and offers… read more

Your next battery

November 25, 2003

Scientists are scrambling to perfect the fuel cell as a methanol-powered source for energy-hungry laptops and other portable devices.

Intel’s Tiny Hope for the Future

November 25, 2003

Intel is thinking even smaller: tiny sensor chips that network with each other — inside everything on earth.

It foresees networks consisting of thousands of motes, located wherever there’s a need for data collection, streaming real-time data to one another and to central servers.

The goal is to halve the size and price of a mote (a tiny sensor, transmitter and antenna to communicate with other motes) every… read more

Will December make or break the Internet?

November 25, 2003

The Internet sits at a crossroads. The World Summit on the Information Society, organized by the International Telecommunications Union, will bring together the heads of over 60 governments in Geneva on December 10 to 12.

The goal: wrest control from ICANN, which is backed by the U.S., Europe and English-speaking partners such as Australia.

New Machine Can Detect Drugs Like Dogs

November 25, 2003

Georgia Tech researchers have developed a machine that can instantly sniff out illegal drugs.

From a few feet away, the device can “smell” as little as one-trillionth of a gram. So far it’s only programmed to detect cocaine, but it could be developed to sniff out other drugs, anthrax, bombs, chemical agents and even cancerous cells.

Intel produces chips for next generation

November 25, 2003

Intel said it has produced chips with the 65-nanometer manufacturing process and will start to mass-manufacture chips on the process in 2005, a strong sign the company will continue to keep pace with Moore’s Law.

Reducing the size of the chip improves performance, reduces costs, and can potentially cut energy consumption. The 65-nanometer chips will contain strained silicon and a low-k (low capacitance) dielectric layer, which, in addition to… read more

The Muse Is in the Software

November 24, 2003

“Inventing is about catching the wave,” said Ray Kurzweil, who addressed a national convention of inventors in Philadelphia last Monday. “Most inventions fail not because the inventor can’t get them to work but because the invention comes at the wrong time.”

Kurzweil’s latest invention, with engineer John Keklak, is cybernetic poet, recently awarded patent No. 6,647,395. Like many of Kurzweil’s inventions, it’s based on pattern recognition.

How to foster innovation

November 24, 2003

With the pace of innovation doubling every decade, inventors should “target the world when the product is launched, not when the project is launched,” said Ray Kurzweil in a keynote speech at the recent 8th Annual Independent Inventors Conference in Philadelphia, presented by the U.S. Patent and Trademark Office.

Kurzweil offered several other tips to inventors. For example:

  • Watch for”false pretenders”: an upstart threatens to

    Intel charts new seas

    November 24, 2003

    Intel Corp. has made available its chip-making nanotechnology tools to cancer researchers to diagnose and study cancer.

    Intel is building a room-sized machine called the Raman Bioanalyzer System at the Fred Hutchinson Cancer Research Center in Seattle. It beams lasers onto tiny medical samples to produce images of the molecules’ chemical structures.

    The bioanalyzer also will have applications beyond cancer research for detecting single-molecule changes in any living… read more

    Real-time movies of solid-to-liquid phase transitions

    November 24, 2003

    Chemists have captured atom-scale images of the melting process, revealing the first images of the transition of a solid into a liquid at the timescale of femtoseconds.

    “Imagine being able to see atoms as they move in real time,” says Professor R. J. Dwayne Miller of the University of Toronto departments of Chemistry and Physics. “Chemistry and biology are fundamentally governed by changes in atomic structure. We now have… read more

    UK debut for ‘blind’ mobile

    November 24, 2003

    The first mobile phone designed specifically for blind and partially sighted people will go on sale in Spain next week. A speech synthesizer reads everything that would normally appear on the screen and speaks the name or number of incoming callers.

    Could I Get That Song in Elvis, Please?

    November 24, 2003

    Vocaloid software, due out in January from Yamaha, allows users to create synthesized songs in a life-like concert-quality voice.

    To create the virtual performer’s “vocal font,” technicians record a singer performing as many as 60 pages of scripted phoneme articulations along with assorted pitches and techniques like glissandos and legatos.

    The software may allow for “vocal reanimation” of celebrity singers, like Elvis.

    Vocaloid could be used as… read more

    Gene-Altering Revolution Nears the Pet Store: Glow-in-the-Dark Fish

    November 24, 2003

    A Texas company will soon start selling The GloFish, a genetically engineered zebra fish containing a gene from a sea coral that makes the fish bright red under normal light and fluorescent under ultraviolet light.

    Meet Paro, the therapeutic robot seal

    November 21, 2003

    Prototypes of Paro, a stuffed animal seal robot, are being tested at nursing homes and with autistic and handicapped children.

    Surface tactile sensors beneath its fur and whiskers trigger Paro to move and respond to petting: eyes open and close, flippers move. Just holding and stroking the critter has a calming effect.
