Alaska's shorebirds exposed to mercury
Shorebirds breeding in Alaska are being exposed to mercury at levels that could put their populations at risk, according to new research from The Condor: Ornithological Applications.Thanks to atmospheric circulation and other factors, the mercury that we deposit into the environment tends to accumulate in the Arctic. Mercury exposure can reduce birds' reproductive success and sometimes…

Weathered oil from DW Horizon spill may threaten fish embryos and larvae development
A research team led by scientists at the University of California, Riverside and the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science have found that ultraviolet light is changing the structure of the Deepwater Horizon (DWH) oil components into something more toxic, further threatening numerous commercially and ecologically important fishes. The DWH…

How Growing Sea Plants Can Help Slow Ocean Acidification
Researchers are finding that kelp, eelgrass, and other vegetation can effectively absorb CO2 and reduce acidity in the ocean. Growing these plants in local waters, scientists say, could help mitigate the damaging impacts of acidification on marine life.Oregon’s picturesque Netarts Bay has long been known for its oysters. But Netarts, like the whole west coast…

Ice algae: The engine of life in the central Arctic Ocean
Algae that live in and under the sea ice play a much greater role for the Arctic food web than previously assumed. In a new study, biologists of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) showed that not only animals that live directly under the ice thrive on carbon produced…

Climate change is apparently shifting clouds towards the poles
The way clouds cover the Earth may be changing because of global warming, according to a study published Monday that used satellite data to track cloud patterns across about two decades, starting in the 1980s.Clouds in the mid-latitudes shifted toward the poles during that period, as the subtropical dry zones expanded and the highest cloud-tops…

Regulating particulate pollution
An MIT analysis of how best to reduce fine particulate matter in the atmosphere has brought some surprising results. Due to past regulations, levels of key emissions that form those harmful particles are now lower than they were a decade ago, causing some experts to suggest that cutting them further might have little effect. Not…

Monkeys in Brazil have used stone tools for hundreds of years at least
New archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years, and the new research paper asks whether human behaviour was influenced through watching the monkeys. Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. In…
