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.

    Next Big Thing in Biotech: RNAi

    November 21, 2003

    A new tool that blocks disease-causing genes, RNA interference (RNAi), could lead the way for the next wave of blockbuster drugs in biotechnology.

    Nano-transistor self-assembles using biology

    November 21, 2003

    A functional electronic nano-device has been manufactured using biological self-assembly for the first time. It harnesses the construction capabilities of DNA and the electronic properties of carbon nanotubes to create a self-assembling nano-transistor.

    The team used proteins to allow carbon nanotubes to bind to specific sites on strands of DNA. They then turned the remainder of the DNA molecule into a conducting wire. The team has already connected two… read more

    Senate approves nanotech bill

    November 20, 2003

    The Senate passed a version of its 21st Century Nanotechnology Research and Development Act. It gives nanotech a permanent home in the federal government, putting the National Nanotechnology Initiative into law and authorizing nearly $3.7 billion over four years for research and development.

    Award for new virtual TV guide

    November 20, 2003

    A virtual TV guide aimed at helping visually impaired people can switch channels at the command of the viewer.

    The software chats to viewers about what they want to see, a computer linked to the TV uses voice recognition to accept their answer and then switches the set to the correct channel.

    Segway robot opens doors

    November 20, 2003

    MIT researchers have crossed a robotic arm with the bottom half of a Segway to make a robot that can traverse hallways and open doors.

    The researchers are aiming to give the robot the abilities to recognize whether it’s in a room or hallway, recognize and manipulate objects, take instructions, and learn.

    “Hope Is a Lousy Defense.”

    November 20, 2003

    Bill Joy talks about greedy markets, reckless science, and runaway technology.

    Q: Whatever happened to the book you were writing to follow up the article?

    Joy: I’ve written two manuscripts. The first was a wake-up call – that’s obviously not the book we need anymore. The second was prescriptive, and the problem is, I’m not satisfied with the prescriptions that I have. You don’t get two shots at… read more
