    Electron (or 'Hole') Pairs May Survive Effort to Kill Superconductivity

    Scientists seeking to understand the mechanism underlying superconductivity in "stripe-ordered" cuprates--copper-oxide materials with alternating areas of electric charge and magnetism--discovered an unusual metallic state when attempting to turn superconductivity off. They found that under the conditions of their experiment, even after the material loses its ability to carry electrical current with no energy loss, it retains some conductivity--and possibly the electron (or hole) pairs required for its superconducting superpower.

    Berkeley Lab Technology Provides Clarity Amid Hawaiian Water Contamination Concerns

    For years, routine testing has shown that watersheds of the Mahaulepu Valley and Waikomo Stream in southeast Kauai frequently contain high counts of potentially pathogenic fecal indicator bacteria (FIB). To better understand the cause of the high FIB counts, the DOH commissioned a study by Berkeley Lab microbial ecologists Gary Andersen and Eric Dubinsky. After using a powerful microbial detection tool called the PhyloChip, the scientists concluded that most of the past monitoring results were false positives.
