We summarize the week's scientific breakthroughs every Thursday.
- Tech
EPA council sets priorities
The Environmental Protection Agency's Science Policy Council has outlined the agency's nanotechnology-research needs.
- Computing
Games Theory
Online games can not only entertain but also provide valuable data for researchers tackling computer-vision and other tough computational problems.
- Tech
Unlocking the Gaits: Robot tests locomotion switch
A blocky, bright-yellow robot that would look at home in a toy chest moves like a salamander, just as its inventors intended.
- Tech
Transferred Touch: Sensory rewiring to improve prosthetics
Transferring a lost limb's nerves to other areas of the body might one day permit an amputee to feel the heat of a coffee cup with an artificial hand.
- Tech
Wrinkle, wrinkle, little polymer
Scientists have developed a cheap and easy way to create specific patterns of tiny wrinkles on the surface of a flexible and commonly used polymer, a technique that could be used to fabricate an assortment of microdevices.
- Tech
Making a 3-D Microscope: Technique brings entire sample into focus
A new imaging technique creates microscopic three-dimensional views of tissues within a patient's body and can update those images several times a second.

A backpack with a suspension system
A new backpack design that uses elastic cords to minimize the pack's vertical motion could lessen bodily strain on wearers and reduce the effort required to carry a load.
- Computing
Digital Fingerprints
New methods to identify Internet users by their behavior can uncover criminals online, but these techniques may also track millions of innocent users.
- Tech
Loopy Light: Rings that delay photons may advance microchips
Chains of tiny, high-precision, light-conducting loops of silicon may open the door to using optical circuits to carry enormous data flows within computer chips.
- Tech
Ahead of the Curve: Novel morphing wing may reduce aircraft’s fuel use
A prototype aircraft wing has demonstrated in its first flight tests that its morphing might save fuel.
- Tech
Shape shifter shifts twice
Certain plastics known as shape-memory polymers switch to predetermined shapes when triggered by heat or light. Now, researchers have developed more-versatile versions of such polymers. When heated, each of the new triple-shape polymers switches to a second shape. Then, at a higher temperature, the plastic changes to a third form. “For some applications, [these] more-complex […]
