Army looks to nanotechnology, robotics

July 3, 2001

The U.S. Army plans to use nanotechnology to develop an interactive, protective uniform for soldiers and nanoscale methods of releasing drugs and preventing infectious diseases. It’s also planning robotics systems to do more of the dangerous work.

Quantum dots to barcode DNA

July 3, 2001

A system for bar-coding DNA using brilliant crystals called quantum dots could revolutionize our ability to identify genes in the human genome.

A group at Indiana University in Bloomington has developed a way to embed quantum dots in tiny Styrofoam-like beads attached to DNA to create unique labels. The paper
appears in Nature Biotechnology.

The dots are semiconductor crystals of cadmium selenide wrapped in shells of… read more

Wireless artificial heart implanted

July 3, 2001

University of Louisville surgeons made medical history yesterday, cutting a damaged heart out of the chest of a terminally ill patient and replacing it with an artificial pump that has no wires to the outside world, according to a unconfirmed report.

The plastic-and-metal heart, called the AbioCor, uses an implanted battery that powers the motor. It recharges from a coil that transfers energy through the skin.

Nanotubes are the new superconductors

July 2, 2001

Nanotubes exhibit superconductivity below 20 degrees Kelvin, Hong Kong University of Science and Technology researchers have reported in Science magazine.

The superconductivity is due to enhanced coupling between phonons and electrons.

The real-life future for A.I. robots

Flesh Fair: orgas vs. mechas

Some researchers believe the A.I. film’s robots are a reasonable approximation of where robotics is headed.

Ray Kurzweil believes human emotions, especially love, are half a century away from being replicated by machines. Should that day arrive, says Kurzweil, machines will have become human.

The robot-boy David expresses an unrequited love for his human owner, all the while wishing he were “a real boy.”

‘Artificial personality’ to get psychological test

June 30, 2001

A psychological test will be administered to a machine-based “artificial personality” known as GAC (Generic Artificial Consciousness).

GAC — pronounced ‘Jack’ — is being developed at the Mindpixel Digital Mind Modeling Project with the collaboration of nearly 40,000 Internet users, who have input more than 355,000 individual items of human consensus experience. The project’s organizers hope to build an accurate statistical model of an average human mind… read more

Artificial Intelligence for the New Millennium

June 30, 2001

For those wondering when artificial intelligence will truly take root, here’s a bulletin: it already has.

The “A.I.” movie might awaken venture capitalists to the commercial potential of research projects in controversial areas like the emotional dimensions of machine intelligence. The film asks what would become of a childlike robot programmed to love a human mother. Researchers said “A.I.” could build support for today’s more mundane goals of using… read more

Ultrafast Electron Spin Manipulation Allows for High-speed Quantum Computing

June 29, 2001

A new way to change quantum spin states on ultrafast time scales (femtoseconds) by manipulating electron spins could pave the way for all-optical quantum computation in solids by loosening the stringent requirements on coherence times.

Researchers at the University of California at Santa Barbara used 10-13 second pulses of laser light to “tip” the spin alignment of the electrons.

The results were published in the June… read more

Cinema’s computers and robots still think like people

June 29, 2001

Hollywood’s robots and computers still think like humans, whether they are playing Gandhi or Hitler. In reality, would they not think quite differently from us —- as aliens, in fact?

Only one film has ventured down this route and it comes from Russia, Andrei Tarkovsky’s “Solaris” (1972). Based on a novel by a Polish sci-fi writer, Stanislaw Lem, it imagines a world with a mind of its own that… read more

Congress Hears Military Nanotech Plans

June 29, 2001

Nanotechnology promises immense gains for the Department of Defense, especially in computers, materials and propulsion, but its benefits are still decades away and likely to be difficult and costly to mass produce, lawmakers were told Tuesday.

DoD plans call for developing advanced materials for embedded computing, composites and so-called “smart materials.” DARPA uses nanotechnology and micro-electromechanical systems or MEMS for a range of purposes. Researchers are developing so-called biofluidic… read more

Blood cells turn cancer killers

June 28, 2001

Lifesaving drugs might soon be dispatched with pinpoint accuracy to diseased organs by using a patient’s own red blood cells as drug-carrying torpedoes.

The drug is released precisely where it is needed by focusing ultrasound on the diseased tissue to make the blood cells — which have been exposed to a pulsed electric field and infused with the drug — burst open. This should allow potent drugs such as… read more

Measuring performance in virtual environments

June 28, 2001

Scientists are beginning to measure how humans perform in virtual environments, including gender-based differences, and how some virtual environments may favor individual aptitudes or learning styles.

People’s perceptions of distance, space and movement are often exaggerated or altered in computer simulations.

A.I.: Unraveling the Mysteries

June 28, 2001

Kubrick diehards have been playing an educated guessing game about A.I. … And in recent months, a younger, more Web-savvy set has been engaged in an elaborate interactive game that’s actually a marketing effort for the movie ….

Uploading Life: Send Your Personality to Space

June 28, 2001

The gradual merging of human beings with their computers over the next century gives rise to the prospect of interstellar immortality, said William Sims Bainbridge at a recent George Washington University Space Policy Institute symposium.

Cognitive neural science, genetic engineering, nanotechnology and information systems may allow the founding of a cosmic civilization, a possibility that does not require flying living human bodies and all the necessities of life to… read more

IBM announces world’s fastest silicon-based transistor

June 25, 2001

IBM has built the world’s fastest silicon-based transistor, operating at 210 GHz while drawing just 1 mA of current. This represents an 80 percent performance improvement and a 50 percent reduction in power consumption over current designs, claims IBM.

IBM expects the new technology will result in communications chips at speeds of 100 GHz within two years — five times faster and four years sooner… read more
