Virtual Soldiers? Dream on, Darpa

August 15, 2003

The Pentagon wants to digitally recreate every element of a soldier’s body, and embed it all on a chip in the soldier’s dog tags. This Virtual Soldier program could help battlefield medics make quicker, more accurate diagnoses of combat trauma and help save lives.

“Every single person in the United States will have an electronic medical record,” said Dr. Richard Satava, manager of the Virtual Soldier program and professor… read more

Nanoparticles may be good for you

August 14, 2003

University of Central Florida researchers have found that brain cells exposed to a single dose of ten-nanometer-size oxide particles routinely outlived untreated cells by three- to four-fold and remained functional.

Nanoparticles also have potent anti-inflammatory properties, they discovered. The investigators hope to create a coating from the particles that could be used for vascular and orthopedic implants, stents and other devices prone to inflammatory reactions.

The nanoparticle anti-oxidants… read more

Accelerating Change

August 14, 2003

The defining political conflict of the 21st century is shaping up to be the battle over the future of technology. Fortunately, technological progress doesn’t just have opponents; it also has boosters.

The rise of neo-Luddism is calling forth self-conscious defenders of technological progress. Growing numbers of extropians, transhumanists, futurists and others are entering the intellectual fray to do battle against the neo-Luddite activists who oppose biotechnology, nanotechnology, and new… read more

Program detects tiny differences in images

August 13, 2003

Scientists at the U.S. Department of Energy’s Idaho National Engineering and Environmental Laboratory have developed a program that detects slight differences between digital images that signal early stages of disease.

The program aligns images, to within a fraction of a pixel, from hand-held or otherwise imprecise cameras. The alignment compensates for differences in camera angle, height, zoom or other distractions that previously confounded comparisons. There are also a variety… read more

How to count atoms

August 13, 2003

NIST researchers are developing a diode-laser based interferometer device that can resolve distances smaller than the radius of an atom and that could serve as a reliable method for writing 10-nanometer-sized features on silicon.

They are packaging the new technology into a scanning tunneling microscope (STM) system designed to write patterns with dimensions determined by counting the atoms that make up the patterns’ structural features. Ultimately aiming for an… read more

IBM Takes Search to New Heights

August 13, 2003

IBM is using a combination of artificial intelligence techniques to create “Google on steroids.”

Return of the green Luddites

August 12, 2003

Environmental activists want governments to enforce the “precautionary principle,” which states that when there is any risk of a major disaster, scientific progress must halt….

“The folks at Greenpeace must have been watching too many ‘Matrix” and ‘Terminator’ movies, because their report spends a few dozen pages worrying about the threat of ‘predatory machines’ and a ‘robot take-over.’”

The New Diamond Age

August 12, 2003

Diamond microchips could handle higher temperatures than today’s microprocessors, allowing them to run at speeds that would liquefy ordinary silicon.

“If Moore’s law is going to be maintained, processors are going to get hotter and hotter,” says Bernhardt Wuensch, an MIT professor of materials science. “Eventually, silicon is just going to turn into a puddle. Diamond is the solution to that problem.”

Casimir force measured precisely

August 12, 2003

The latest in a series of experiments has yielded precise measurement of the Casimir force, which could make nanoscale machines behave erratically.

The Casimir force has to do with the minute pressure that real and virtual photons of light exert when they bump against an object. To manipulate light beams at the nanoscale will likely require tiny mirrors that can pivot to reflect photons down different channels.

Neural-Network Technology Moves into the Mainstream

August 12, 2003

Real-time data mining, powered by neural-network technology, has begun to remake the way large corporations manage customer accounts for fraud detection and customer-behavior prediction, using relational databases and Predictive Model Markup Language.

Visionaries Outline Space Exploration Advances at Telluride TechFest

August 12, 2003

New technological advances will bring about great change in both robotic and human exploration throughout the 21st century, according to visionary thinkers and futurists in science, technology, and the arts gathered at the annual Telluride Tech Festival.

Star supply dwindling

August 12, 2003

Star formation is now 30 times slower than it was 6 billion years ago, a University of Edinburgh team has found. More stars are fizzling out than are being born.

3-D Printing’s Great Leap Forward

August 12, 2003

Rapid prototyping machines (3-D printers) — which carve a model of an object out of metal, paper, plastic or starch – can now build moving parts, not just block models. University of California at Berkeley researchers are developing “flextronic” devices — or flexible mechatronics — a small model with flexible joints and electronic parts built in.

Fastest network simulations

August 11, 2003

Researchers at the Georgia Institute of Technology have created the fastest detailed computer simulations of computer networks ever constructed, simulating networks containing more than 5 million network elements and more than one million web browsers in near real time.

This work will lead to improved speed, reliability and security of future networks such as the Internet, according to Professor Richard Fujimoto, lead principal investigator of the DARPA-funded project.… read more

‘Spintronics’ could enable a new generation of electronic devices

August 11, 2003

Theoretical physicists at Stanford and the University of Tokyo says they have discovered the equivalent of a new “Ohm’s Law” for spintronics.

”Unlike the Ohm’s Law for electronics, the new ‘Ohm’s Law’ that we’ve discovered says that the spin of the electron can be transported without any loss of energy, or dissipation,” says Shoucheng Zhang, a physics professor at Stanford. “Furthermore, this effect occurs at room temperature in materials… read more
