Old permafrost carbon released
Using indicator molecules, a team of researchers headed by ETH Zurich demonstrates that carbon stored in the Arctic permafrost is being mobilised in Eurasian river basins.
Two strains of bacteria team up, thrive on limited resources
In a discovery that further demonstrates just how unexpected and unusual nature can be, scientists have found two strains of bacteria whose symbiotic relationship is unlike anything seen before.
Study finds novel worm community affecting methane release in ocean
Scientists have discovered a super-charged methane seep in the ocean off New Zealand that has created its own unique food web, resulting in much more methane escaping from the ocean floor into the water column.
Scientists find new arsenic threat in deep water wells
"Dig deep" to avoid naturally occurring arsenic contamination has been promoted as an answer to obtaining safe water in South Asia, which has experienced mass poisoning. But arsenic has been found in numerous ...
Ice ages only thanks to feedback
Ice ages and warm periods have alternated fairly regularly in the Earth's history: the Earth's climate cools roughly every 100,000 years, with vast areas of North America, Europe and Asia being buried under ...
Westerly winds and CO2 levels
The end of the last Ice Age was preceded by a gradual rise in atmospheric CO2. A new study supports the idea that a shift in the position, and increase in the intensity, of zonal westerly winds in the Southern ...
Study shows legacy of pesticides difficult to avoid
A University of Otago study shows that the tell-tale legacy in rural South Island areas of pesticides banned many years ago remains, regardless of the type of sheep and beef farming now taking place on the land.
Earthquakes trigger undersea methane reservoirs: study
Earthquakes can rip open sub-sea pockets of methane, a highly potent greenhouse gas, according to a study by German and Swiss scientists published on Sunday.
