With Mars and Europa out of reach, many scientists have turned to studying some of the Arctic and Antarctic microbes that have adapted to similarly harsh conditions on Earth.
University of Michigan researchers and their University of Hawaii colleagues say they've solved the longstanding mystery of how mercury gets into open-ocean fish, and their findings suggest that levels of the toxin in Pacific ...
Vast amounts of toxic mercury are accumulating in the Arctic tundra, threatening the health and well-being of people, wildlife and waterways, according to a UMass Lowell scientist investigating the source of the pollution.
The Environmental Protection Agency on Tuesday called for the nation's first limits on mercury emissions from the more than 100 cement factories across the U.S.
Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found.
A highly toxic form of mercury could jump by 300 to 600 percent in zooplankton—tiny animals at the base of the marine food chain—if land runoff increases by 15 to 30 percent, according to a new study.
Mercury pollution is a global problem with local consequences: Emissions from coal-fired power plants and other sources travel around the world through the atmosphere, eventually settling in oceans and waterways, where the ...
In any given year, workers in artisanal and small-scale gold mining shops in remote locales like Brazil and Peru release an estimated 700 tons of airborne mercury from their rooftops.
More than 140 countries agreed Saturday on a ground-breaking treaty to rein in the use and emission of health-hazardous mercury, the UN said, but environmental activists lamented it did not go far enough.
Air pollution controls installed at an Oregon coal-fired power plant to curb mercury emissions are unexpectedly reducing another class of harmful emissions as well, an Oregon State University study has found.
