- Novel semiconductor structure bends light 'wrong' way -- the right direction for many applications
10-14-2007 · EurekAlert!
A Princeton-led research team has created an easy-to-produce material from the stuff of computer chips that has the rare ability to bend light in the opposite direction from all naturally occurring materials. This startling property may contribute to significant advances in many areas, including high-speed communications, medical diagnostics and detection of terrorist threats.

- A step nearer to understanding superconductivity
06-06-2007 · EurekAlert!
Transporting energy without any loss, travelling in magnetically levitated trains, carrying out medical imaging (MRI) with small-scale equipment: all these things could come true if we had superconducting materials that worked at room temperature. Today, researchers at CNRS have taken another step forward on the road leading to this ultimate goal. They have revealed the metallic nature of a class of so-called critical high-temperature superconducting materials.

- RACE: a statewide model of better, faster heart attack care
11-04-2007 · EurekAlert!
A North Carolina team of doctors, nurses, hospitals and emergency medical service workers has come up with a way to provide faster, more effective treatment for heart attack patients. It doesn't require expensive drugs or fancy new equipment. But it does require competitors to become collaborators, and it calls on everyone involved to "move treatment forward" -- empowering emergency services personnel in the field to diagnose a heart attack, something only physicians had done before.

- Contrast agent puts new light on diagnosing breast cancer
03-26-2007 · EurekAlert!
Scientists in the laboratory of Dr. John Frangioni, M.D., Ph.D., associate professor of medicine and radiology at Harvard Medical School, have developed a contrast agent that selectively targets and highlights malignant micro-calcifications in the breast, while ignoring similar micro-calcifications found in benign breast conditions. The new, simpler way to detect malignant tumors will be described in March at the 233rd national meeting of the American Chemical Society in Chicago.

- New study finds infant hearing test results may predict sudden infant death syndrome
07-26-2007 · EurekAlert!
One of the greatest medical mysteries of our time has taken a leap forward in medical understanding with new study results announced by Dr. Daniel D. Rubens of Seattle Children's Hospital. Rubens' study published in Early Human Development found all babies in a study group who died of SIDS universally shared the same distinctive difference in their newborn hearing test results for the right inner ear, when compared to infants who did not have SIDS.
