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

Quantum logic gate lights up

August 11, 2003

University of Michigan physicists have taken another important step towards making a quantum computer. They have created a logic gate using two electron-hole pairs, also known as “excitons,” in a quantum dot.

More than six degrees separate us

August 8, 2003

An e-mail experiment has confirmed the famous “six degrees of separation” of human social networks, but revealed that individuals don’t necessarily benefit from their connectedness.

Witchcraft: Sinatra lives

August 8, 2003

In October, Radio City Music Hall in New York will feature a lifelike virtual performance by Frank Sinatra.

Video images of the singer will be projected onto three-dimensional screens as his recorded voice plays over the sound system. The producers will use rotoscoping to black out background imagery and project Sinatra across a series of moveable 3-D panels.

Musical roots may lie in human voice

August 7, 2003

Key universal features in world music may have their roots in the ever-present sound of the human voice during the course of evolution, suggests a new study.

The analysis of thousands of recorded speech samples found peaks in acoustic energy that precisely mirror the distances between important notes in the twelve-tone scale, the system that forms the foundation of almost all music.

World’s first cloned horse is born

August 7, 2003

The Laboratory of Reproductive Technology in Cremona has cloned the world’s first horse, which could help boost good breeds and might even help replicate equine champions.

UCLA Launches Brain Mapping Project

August 7, 2003

Researchers have compiled an atlas that contains digitally mapped images of the brain. It allows researchers to compare and contrast brain images captured from 7000 people living in seven nations on four continents.

Available free on the Internet, the atlas charts brain activity, pinpointing the seat of functions such as speech, memory, emotion and language and highlighting how those locations can vary among individuals and populations.

Robot links doctors and patients remotely

August 6, 2003

A high-tech robot being tested at The Johns Hopkins Hospital could be used to remotely link patients with their physicians.

Looking at a computer terminal, the doctor directing the robot sees what the robot sees and hears what the robot hears. At the other end, patients can see and talk to the doctor’s face displayed on a flat screen that sits on the robot’s “shoulders.” The devices are connected… read more

Nanolitho effort harnesses self-assembly

August 6, 2003

Nanoscale patterning of silicon substrates with regular, repeatable, atomically perfect application-specific templates could enable manufacturable nanoscale chips within the decade, according to scientists at the University of Wisconsin’s Materials Research Science and Engineering Center (Madison).

The technique can achieve dimensions of tens of nanometers and could someday result in a computer with 4,000 Gbytes of memory. The team used block co-polymers that “self-assemble like snowflakes,” according to their report,… read more

Scientists debate value of citizens’ advisory panels

August 6, 2003

The National Science Foundation is experimenting with a system of citizens’ advisory panels to consider the ethical, social and practical implications of new technologies and recommend policies that might reduce misunderstanding and obstruction on issues such as genetically modified foods and nanotechnology.

How Robots Will Steal Your Job

August 6, 2003

Humanoid robots will be widely available by the year 2030 and able to replace jobs currently filled by people in areas such as fast-food service, housecleaning and retail, says Marshall Brain, founder of HowStuffWorks.

Unless ways are found to compensate for these lost jobs, Brain estimates that more than half of Americans could be unemployed by 2055.
