Researchers make electron spin useful

In the global race for possibilities for the use of electron spin, an international research team is right at the forefront: The researchers have managed to maintain the polarisation of nuclear spin and its associated electron spin for some ten minutes - a virtually endless amount of time for typical computer calculation steps.

Nanoparticle could help detect cancer and other diseases early

Researchers have created the first nanoparticle capable of detecting and imaging trace amounts of hydrogen peroxide in animals. The nanoparticles, thought to be completely nontoxic, could someday be used as a simple, all-purpose diagnostic tool to detect the earliest stages of any disease that involves chronic inflammation, including cancer, Alzheimer's disease, heart disease, and arthritis.
