New clues to mechanism for 'colossal resistance' effects

08-17-2007 · EurekAlert!

Experiments at the US Department of Energy's Brookhaven National Laboratory, shed new light on some materials' ability to dramatically change their electrical resistance in the presence of an external magnetic or electric field. Small changes in resistance underlie many electronic devices, including some computer data storage systems. Understanding and applying dramatic resistance changes, known as colossal magnetoresistance, offers tremendous opportunities for the development of new technologies, including data-storage devices with increased data density and reduced power requirements.

  3. Strain has major effect on high-temp superconductors
    02-15-2007 · EurekAlert!
    Just a little mechanical strain can cause a large drop in the maximum current carried by high-temperature superconductors, according to novel measurements carried out by NIST. The effect adds a new dimension to designing superconducting systems and it also provides a new tool that will help scientists probe the fundamental mechanism behind why these materials carry current with no resistance.

    10-18-2006 · EurekAlert!
    Oregon Health & Science University research showing stress triggers relapse of methamphetamine abuse in mice could be a step toward developing a drug to curb this frustrating obstacle to recovery. Results of the study not only validate earlier studies on the effects of stress on drug relapse in humans, they also show a compound researchers used to mimic metabolic changes that occur during stress creates a useful model for studying this effect in the laboratory.

  8. Study finds reduced brain growth in alcoholics with family drinking history
    02-21-2007 · EurekAlert!
    Previous studies have shown that alcoholics have smaller brain volumes than non-alcoholics, an effect widely believed to be due to the toxic effects of ethanol. In this study, researchers found reduced brain growth among alcohol-dependent individuals with a family history of alcoholism or heavy drinking compared to those with no such family history. The finding demonstrates that reduced brain growth occurs among these individuals even before the onset of alcohol dependence.
