Over nearly nine years, the Daya Bay Reactor Neutrino Experiment captured an unprecedented five and a half million interactions from subatomic particles called neutrinos. Now, the international team of physicists has reported the first result from the experiment's full dataset -- the most precise measurement yet of theta13, a key parameter for understanding how neutrinos change their 'flavor.' The result will help physicists explore some of the biggest mysteries surrounding the nature of matter and the universe.

Using NASA's SOFIA observatory and other data resources, an international team of astronomers has uncovered evidence of metals in local galaxies -- found to be deficient in earlier studies -- by analyzing infrared data gathered during a multiyear campaign.

Researchers demonstrate that under low fluid shear force conditions that simulate those found in microgravity culture during spaceflight, the foodborne pathogen Salmonella infects 3-D models of human intestinal tissue at much higher levels, and induces unique alterations in gene expression.
