Klima­wandel: Gletscher­schmelze nicht mehr abwend­bar

Forscher der Universitäten Bremen und Innsbruck zeigen in einer aktuellen Studie, dass das weitere Abschmelzen der Gletscher im laufenden Jahrhundert nicht mehr verhindert werden kann – selbst wenn alle Emissionen gestoppt würden. Über das 21. Jahrhundert hinaus hat unser Verhalten aber massive Auswirkungen: 500 Meter Autofahrt kosten langfristig ein Kilo Gletschereis. (more…)

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…)
