An alloy that may improve high-temperature electronics in oil, gas and geothermal wells fills a unique niche.

Under the skin, a tiny laboratory

Posted: 19 Mar 2013 05:21 PM PDT

Scientists have developed a tiny, portable personal blood testing laboratory: a minuscule device implanted just under the skin provides an immediate analysis of substances in the body, and a radio module transmits the results to a doctor over the cellular phone network. This feat of miniaturization has many potential applications, including monitoring patients undergoing chemotherapy.

A compact, self-contained sensor recorded and transmitted brain activity data wirelessly for more than a year in early stage animal tests, according to a new study.

Laser-like photons signal major step towards quantum 'Internet'

Posted: 19 Mar 2013 09:42 AM PDT

The realization of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from "solid-state" chips, bringing us closer to the quantum "Internet."

Electrons are not enough: Cuprate superconductors defy convention

Posted: 19 Mar 2013 06:17 AM PDT

To engineers, it's a tale as old as time: Electrical current is carried through materials by flowing electrons. But physicists have now found that for copper-containing superconductors, known as cuprates, electrons are not enough to carry the current.

New nanomedicine resolves inflammation, promotes tissue healing

Posted: 19 Mar 2013 06:10 AM PDT

Researchers have developed biodegradable nanoparticles that are capable of delivering inflammation-resolving drugs to sites of tissue injury. The nanoparticles, which were successfully tested in mice, have potential for the treatment of a wide array of diseases characterized by excessive inflammation, such as atherosclerosis.
