We summarize the week's scientific breakthroughs every Thursday.
- Tech
Biotechnology may fortify U.S. Army
A government-sponsored study says the U.S. Army may benefit from advances in biotechnology during the next 25 years, including sensors that identify soldiers by the food they ate, protein-based computers, near-instant vaccines, and automated wound treatments.
- Tech
Optics oddity challenges microchip makers
An obscure optical effect called instrinsic birefringence has suddenly appeared as a threat to technology for making denser, faster microchips.
- Tech
Dances with Robots
Soldiers, rescue workers, and others may attain superhuman strength, speed, and endurance as a result of a new military program to develop powered robotic exoskeletons contoured to a person's body.
- Tech
Device fingers chemical thugs at scene
A compact, new instrument exploits quantum mechanics to rapidly identify illegal drugs, pollutants, and other chemicals, on the spot.
- Tech
Robosaur roams with spring in its step
The novel dinosaur robot Troodon takes two-legged walking machines onto new terrain.
- Tech
Polymer takes dim view of explosives
By spraying surfaces with a light-emitting polymer, researchers have taken a step toward making new sensors for traces of common explosives.

- Tech
Getting Nanowired
Makers of nanowires may overcome the limits that loom for microchip fabrication.
- Tech
Electromagnetism acts oddly in device
Without breaking any physical laws, a novel, fiberglass-copper structure affects microwaves so strangely that a beam of radiation passing through it bends at an angle opposite from what it get bent at an angle opposite from what it would have exiting any other known material.
- Tech
Stuff gets stiffed by unstiff inserts
In an odd twist, material that is so extremely yielding that it is said to have negative stiffness will make already stiff materials even stiffer when it's blended into them.
- Tech
New device opens next chapter on E-paper
Researchers have developed a paperlike plastic that could become the pages of the first electronic books and newspapers.
- Tech
Novel fuel cell gets hot, but not by a lot
A new type of fuel cell that works above the boiling point of water—but not too much above it—may lead to improved nonpolluting power sources suitable for cars and portable electronic gadgets.
