Using a mathematical model, researchers have shed new light on the transition from hunter-gatherer to farming societies. Rather than focusing exclusively on external factors, they looked...
As global temperatures warm, the Southern Ocean -- between Antarctica and other continents -- will eventually release heat absorbed from the atmosphere, leading to projected long-term...
More mammals were living on the ground several million years before the mass extinction event that wiped out the dinosaurs, new research has revealed.
Scientists have released new and more accurate genome sequences for five species of duckweed. Their research reveals the specific genes responsible for some of the plant's...
A new study has found that children exposed to higher levels of air pollution in early and mid childhood have weaker connections between key brain regions....
While the threat that microplastics pose to human and ecological health has been richly documented and is well known, nanoplastics, which are smaller than one micrometer...
Lead, pesticides, brominated flame retardants, plastic additives, polychlorinated biphenyls (PCBs), and heavy metals. This is what researchers found when they collected dead hedgehogs to investigate the...
Mountain snowpacks accumulate snow throughout the winter, building up stores of water that will supply communities across the American West throughout the long dry season. Now,...
One of the ocean currents in the Arctic Ocean is at risk of disappearing this century because of climate change, according to a new study. As...
Human thermoregulation limits are lower than previously thought, indicating that some regions may soon experience heat and humidity levels exceeding safe limits for survival. The study...
