Lightning plus volcanic ash make glass
Researchers have proposed a mechanism for the generation of glass spherules in geologic deposits through the occurrence of volcanic lightning. The existence of fulgurites -- glassy products formed in rocks and sediments struck by cloud-to-ground lightning -- provide direct evidence that geologic materials can be melted via natural lightning occurrence.

Newly discovered hormone mimics the effects of exercise
Scientists have discovered a new hormone that fights the weight gain caused by a high-fat Western diet and normalizes the metabolism -- effects commonly associated with exercising. When tested in mice, the hormone blocked the negative health effects of eating a high-fat diet.

Bird flu: New compound protects 100 percent of ferrets, mice, from H5N1
Medical researchers have developed an antibody which has proven 100 percent protective against the H5N1 virus in two species of animal models.

First scientific publication from data collected at National Synchrotron Light Source II
Just weeks after NSLS-II achieved first light, a team of scientists tested a setup that yielded data on thermoelectric materials. To test the optical performance and components of the beamline, the scientists put a material in the path of the x-ray beam and attempted to characterize its structure as the best way to identify and fix possible flaws or aberrations that the instrument could have caused.

Neuroscientists identify new way several brain areas communicate
Neuroscientists have identified a new pathway by which several brain areas communicate within the brain's striatum. The findings illustrate structural and functional connections that allow the brain to use reinforcement learning to make spatial decisions. Knowing how these specific pathways work together provides crucial insight into how learning occurs. It also could lead to improved treatments for Parkinson's disease.

Creative genius driven by distraction
The literary great Marcel Proust wore ear-stoppers because he was unable to filter out irrelevant noise -- and lined his bedroom with cork to attenuate sound. Now new research suggests why the inability to shut out competing sensory information while focusing on the creative project at hand might have been so acute for geniuses such as Proust, Franz Kafka, Charles Darwin, Anton Chekhov and many others.

Far from home: Wayward star cluster is both tiny and distant
Like the lost little puppy that wanders too far from home, astronomers have found an unusually small and distant group of stars that seems oddly out of place. The cluster, made of only a handful of stars, is located far away, in the Milky Way's 'suburbs.' It is located where astronomers have never spotted such a small cluster of stars before.

Air pollution linked to slower cognitive development in children
Attendance at schools exposed to high levels of traffic-related air pollution is linked to slower cognitive development among 7- to 10-year-old children in Barcelona, according to a new study.

Highly sensitive detection of malaria parasites
New assays can detect malaria parasites in human blood at very low levels and might be helpful in the campaign to eradicate malaria, reports a new study. An international team led by Ingrid Felger, took advantage of genes that have multiple copies in the parasite genome to reveal parasites present at concentrations that are 10 times lower than the detection limit of current standard assays.
