European waters drive ocean overturning, key for regulating climate

      An international study reveals the Atlantic meridional overturning circulation, which helps regulate Earth's climate, is highly variable and primarily driven by the conversion of warm, salty, shallow waters into colder, fresher, deep waters moving south through the Irminger and Iceland basins. This upends prevailing ideas and may help scientists better predict Arctic ice melt and future changes in the ocean's ability to mitigate climate change by storing excess atmospheric carbon.

Opinion: Disease Prediction by Bat Virus Surveys Is a Waste

      As one who has studied bats worldwide for 60 years, I’m deeply concerned regarding the near avalanche of recent articles that needlessly frighten the public into intolerance of bats and lead to exceptionally large funding requests that prominent epidemiologists believe will actually harm public health by diverting limited resources. Kerry Grens’s article, “Newly Identified Virus Similar to Ebola, Marburg,” on January 9 in The Scientist will aid in the waste of public health funds while spreading needless fear of some of the world’s most valuable and endangered animals. Long repeated claims, such as those in her article, that virus hunters can predict and protect us from pandemics are without foundation, as are their speculations of bats as uniquely dangerous disease reservoirs.

Not One, Not Two, But Three Fungi Present in Lichen

      Up until 2016, lichen was thought to be a partnership between one alga and one fungus, the classic symbiotic relationship. Then came the observation than in fact lichen harbors two types of fungi—an ascomycete and a newly identified basidiomycete yeast.

Newly Identified Virus Similar to Ebola, Marburg

      Researchers have discovered of a new genus of filovirus carried by fruit bats in China. The genome of the so-called Menglà virus shares sequences with other filoviruses, including Ebola and Marburg, and all three use the same receptor on host cells to gain entry for infection, the scientists reported in Nature Microbiology on Monday
