Software uses sculptor's touch on virtual objects
News & Analysis  
7/27/2004   Post a comment
Virtual reality software has long held the promise of enabling designers to sculpt the sleek curves and contours of a new product from "virtual clay."
Reflector lets LEDs replace light bulbs
News & Analysis  
7/26/2004   Post a comment
Light bulbs create more heat than light. But a professor at Rensselaer Polytechnic Institute (Troy, N.Y.) has invented a 99 percent efficient, omnidirectional reflector that he claims will allow light-emitting diodes to replace conventional light bulbs within five years, saving energy and related cost.

Virtual reality software has long held the promise of enabling designers to sculpt the sleek curves and contours of a new product from "virtual clay," but until recently designers had to learn a whole new procedure for working with computer-aided design (CAD).
ORNL nanoprobe promises on-the-spot toxin IDs

Identifying toxins like the anthrax spores that were mailed to U.S. lawmakers in 2001 has been a process that can take hours to obtain preliminary results and days to get final confirmation.
Cure in sight for 'pink noise' in quantum dots
News & Analysis  
7/26/2004   Post a comment
The troublesome flickering that plagues quantum-dot development today may be closer to a cure, thanks to a team of researchers at the University of Chicago. By analyzing the power spectrum of quantum-dot blinks, the group found that, unlike semiconductors, individual quantum dots exhibit exactly the same qualities as their aggregations, thereby simplifying the measuring apparatus needed to fix the problem.

A recent advance in light-emitting diodes may illuminate the path to replacing light bulbs with LEDs within the next five years.
Electron spin detector may yield denser chips
News & Analysis  
7/19/2004   Post a comment
Spin-dependent transistors could one day harness electron spin to encode up to 10 states (as opposed to binary logic's mere two) in single-electron devices-enabling chips with a million times the density of today's memories, according to the University of Arkansas.

The coursework is no picnic, and once you finish, the job market can be iffy.
Robot copies cats to eliminate spin in free fall
News & Analysis  
7/12/2004   Post a comment
The National Aeronautics and Space Administration's "weightless wonder" aircraft will be the testbed this week for a robot that exhibits catlike motion in free fall. The work could one day lead to designs that eliminate the need for retrorockets, gas jets and gyroscopes in satellites and other spacecraft.
Quantum wells shed light on lightbulb alternative
News & Analysis  
7/5/2004   Post a comment
A promise of future lightbulb replacements that are almost 100 percent efficient came to light in a recent proof-of-concept experiment carried out by the National Nuclear Security Administration's Los Alamos National Laboratory and Sandia National Laboratories.

To say that Andy Weir's The Martian is an exploration of math, Mars, and feces is a slight simplification. I doubt that the author would have any complaints, though.
