Respiratory problems among the population increased markedly in Reykjavik during one of Iceland’s largest volcanic eruptions six years ago. The negative health effects increased most when sulfur dioxide returned from the Atlantic in the...
The shortest amount of time ever measured
A light particle needs just 247 zeptoseconds to cross a molecule made up of two hydrogen atoms. Scientists working with Reinhard Dörner from the University of Frankfurt have now determined – and, according to...
Hot water flows in under the Doomsday Glacier
Measurements from an underwater spacecraft that entered the so-called Doomsday Glacier in western Antarctica, show that the inflow of hot water to the glacier is greater than scientists have hitherto thought. If the giant...
