When NASA’s Aqua satellite passed over Hurricane Norman on Aug. 30 infrared data showed very cold storm tops around a 20 nautical-mile-wide eye.

About 94 million years ago, something happened that led to an unusually high amount of organic material being preserved in oceans around the world.

Study finds injecting fluid into sedimentary rock can produce bigger, more distant earthquakes than injecting into the underlying basement rock.

Researchers have developed a new way to make low-cost, single-atom catalysts for fuel cells — an advance that could make important clean energy technology more economically viable.

The vast majority of lemur species are on the edge of extinction, experts warn. But not every lemur species faces a grim future. There may be as many as 1.3 million white-fronted brown lemurs still in the wild, for example, and mouse lemurs may number more than 2 million, a Duke-led study has shown.

A new paper reviews current knowledge on climate change and biodiversity. In the past, plants and animals reacted to environmental changes by adapting, migrating or going extinct. These findings point to radical changes in biodiversity due to climate change in the future. The paper is published in the scientific journal Trends in Ecology and Evolution by an international group of scientists led by the Center for Macroecology, Evolution and Climate, University of Copenhagen.

A new method of monitoring bird populations that takes into account changes in their songs over time could help scientists understand why some species are declining in the boreal forest.

If governments don’t act decisively by 2035 to fight climate change, humanity could cross a point of no return after which limiting global warming below 2°C in 2100 will be unlikely, according to a new study by scientists in the UK and the Netherlands. The research also shows the deadline to limit warming to 1.5°C has already passed, unless radical climate action is taken. The study is published today in the European Geosciences Union journal Earth System Dynamics.

Seven often wet and muddy researchers can be found bundled in their orange full-body suits sifting through mud on the back deck of the Healy.

The Arctic Ocean is a bustling metropolis of life that ranges in size from whales the size of small ships to microscopic marine bacteria that are 300,000 times smaller than a basketball.
