Hide & Seek: Sterile Neutrinos Remain Elusive

Daya Bay neutrino experiment publishes a new result on its first search for a “sterile” neutrino

BEIJING; BERKELEY, CA; and UPTON, NY—The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a possible new type of neutrino beyond the three known neutrino “flavors,” or types. The existence of this elusive particle, if proven, would have a profound impact on our understanding of the universe, and could impact the design of future neutrino experiments. The new results, appearing in the journal Physical Review Letters, show no evidence for sterile neutrinos in a previously unexplored mass range. (more…)

The Woods Hole Oceanographic Institution (WHOI) will lead the first international, multidisciplinary assessment of the levels and dispersion of radioactive substances in the Pacific Ocean off the Fukushima nuclear power plant—a research effort funded by the Gordon and Betty Moore Foundation.

“This project will address fundamental questions about the impact of this release of radiation to the ocean, and in the process enhance international collaboration and sharing of scientific data,” said Vicki Chandler, Chief Program Officer, Science at the Gordon and Betty Moore Foundation. “It is our hope that through this adverse event, we can increase our current knowledge about various natural and man-made sources of radioactivity in the ocean, and how they might ultimately impact ocean life and health around the world.” (more…)
