In pursuit of dark matter, researchers are doing everything from burying vats of xenon deep underground to sending a balloon floating above the Antarctic. When will their creativity pay off? Physics ...

More Frequent Atmospheric Rivers Are Hindering the Recovery of Arctic Sea Ice Sea ice off the Alaskan village of Kotzebue. (Courtesy Lamont-Doherty Earth Observatory) The Arctic is rapidly losing sea ice, even during winter months, when temperatures are below freezing and ice should be recovering from the summer melt. Now, a new study in the journal Nature Climate Change has found that powerful storm systems called atmospheric rivers are partly responsible; the study finds they are increasingly reaching the Arctic in winter, slowing sea ice recovery and accounting for a third of all winter sea ice decline. “Arctic sea ice decline is among the most obvious eviden...
