Scientists studying mice from the Andes Mountains in Patagonia noticed something they couldn’t explain: the mice from the western side of the mountains were bigger than the ones from the east, but DNA said that they were all from the same species.

A Policy Forum article published today in Science calls for a new approach to regulating genetically engineered (GE) crops, arguing that current approaches for triggering safety testing vary dramatically among countries and generally lack scientific merit – particularly as advances in crop breeding have blurred the lines between conventional breeding and genetic engineering.

Our coastal marine ecosystems are changing rapidly—and some species are moving on.

Global fish stocks will not be able to recover to sustainable levels without strong actions to mitigate climate change, a new study has projected.

Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilisation".

Forests are engaged in a delicate, deadly dance with climate change, hosting abundant biodiversity and sucking carbon dioxide out of the air with billions of leafy straws.

The study highlights a changing climate's impact to water resources and recommends evaluating adaptation strategies to address these vulnerabilities to the water supply.

Less than 500 miles from the North Pole, the Milne Fiord Epishelf Lake is a unique freshwater lake that floats atop the Arctic Ocean, held in place only by a coating of ice. 

Sea ice levels in the Arctic Ocean are rapidly declining, thanks to global warming. 

Trinity College Dublin researchers collaborating with University College London have demonstrated for the first time the low environmental footprint of water fluoridation compared to other preventive measures for tooth decay.
