While the Arctic is melting the Gulf Stream remains Posted: 28 Sep 2014 01:13 PM PDT The melting Arctic is not the source for less saline Nordic Seas. It is the Gulf Stream that has provided less salt. A new study documents that the source of fresher Nordic Seas since 1950 is rooted in the saline Atlantic as opposed to Arctic freshwater that is the common inference.

Bacterial genome important to fuel and chemical production sequenced Posted: 26 Sep 2014 06:35 PM PDT Researchers sequence the entire genome of the Clostridium autoethanogenum bacterium, which is used to sustainably produce fuel and chemicals from a range of raw materials, including gases derived from biomass and industrial wastes.

Predicting electric power outages before they happen Posted: 26 Sep 2014 06:35 PM PDT Power outages are often the result of automated protection measures that ensure power surges or downed power lines don't injure people, damage trees, damage appliances or impact other parts of the grid.

If trees could talk: Forest research network reveals global change effects Posted: 26 Sep 2014 06:13 AM PDT Permafrost thaw drives forest loss in Canada, while drought has killed trees in Panama, southern India and Borneo. In the U.S., in Virginia, over-abundant deer eat trees before they reach maturity, while nitrogen pollution has changed soil chemistry in Canada and Panama. More than 100 collaborators have now published a major overview of what 59 forests in 24 countries teach us about forest responses to global change.
