Afocus on policies to conserve tropical forests for their carbon storage value may imperil some of the world’s most biologically rich tropical forests.

Scientists discover perennial hybrid of wheat, wheatgrass
With a hybrid crop called Salish Blue, scientists at Washington State University have combined wheat and wheatgrass in a new species with the potential to help Pacific Northwest farmers and the environment.
Study tracks memory of soil moisture
The top 2 inches of topsoil on all of Earth’s landmasses contains an infinitesimal fraction of the planet’s water — less than one-thousandth of a percent. Yet because of its position at the interface between the land and the atmosphere, that tiny amount plays a crucial role in everything from agriculture to weather and climate, and even the spread of disease.
The behavior and dynamics of this reservoir of moisture have been very hard to quantify and analyze, however, because measurements have been slow and laborious to make.
The Man in the Zebra Suit Knows the Secret of the Stripes
At four in the morning, Tim Caro roused his colleagues. Bleary-eyed and grumbling, they followed him to the edge of the village, where the beasts were hiding. He sat them down in chairs, and after letting their eyes adjust for a minute, he asked them if they saw anything. And if so, would they please point where?
Halley Research Station Antarctica to close for winter
British Antarctic Survey (BAS) has decided not to winter at Halley VI Research Station for safety reasons. The station, which is located on the floating Brunt Ice Shelf in Antarctica, will shut down between March and November 2017. Changes to the ice, particularly the growth of a new crack, presents a complex glaciological picture that means that BAS scientists are unable to predict with certainty what will happen to the ice shelf during the forthcoming Antarctic winter. As a precautionary measure BAS will remove its people before the Antarctic winter begins.
World's biggest tropical carbon sink found in Congo rainforest
A 145,000 sq km area of peatland swamp forest has been discovered in the Congo Basin, writes Tim Radford, and it holds a record 30 Gt of carbon, equivalent to 20 years of US fossil fuel emissions. Now the race is on to protect it from damaging development that would emit that carbon over coming decades.
