At left, Kelvin-Helmholtz instabilities (KHIs) disturbed by background atmospheric gravity waves at about 90 kilometers altitude over Chile are seen in this image captured on 1 March 2016 by an ...

In our May issue of Eos, we are looking up at a region of Earth’s atmosphere, the scientists in these pages argue, that we aren’t looking at quite enough. That region is called geospace, which ...

Researchers collected sediment cores near the Ebro delta to trace decades of microplastics trapped on the seafloor. Credit: Lena Heins The world produces about 380 million metric tons of plastic ...

High biomass levels make the Palmer Deep submarine canyon in Antarctica a preferred foraging site for penguins, such as these off Anvers Island. New research investigates the origins of this biomass.

Research & Developments is a blog for brief updates that provide context for the flurry of news regarding law and policy changes that impact science and scientists today. Students who have applied for ...

Researchers initially aimed to study the life development of seafloor snails and mussels. However, when their study site was covered in ash from the Hunga volcano, they pivoted to asking questions ...

At a natural underwater laboratory off the coast of Papua New Guinea, researchers examined what happens to a diverse reef ecosystem as it experiences gradually increasing levels of ocean acidification ...

In Antarctic lakes such as Lake Fryxell, fresh water freezes over briny liquid water. New research suggests that the liquid seawater during “snowball Earth” was up to 4 times saltier than modern ocean ...

Scientists collected sediment cores from the Southern Ocean to gather evidence for the existence of a “salty blob” that sequestered carbon deep in the ocean during the last ice age. Credit: Ryan ...

Rocks are important in subsurface engineering, but they are mostly invisible, extremely heterogeneous, and difficult to access. Thus, data on rock properties is scarce and uncertainties are large. Liu ...

The Trump administration has holistically reevaluated the government’s relationship—and how it responds to threats— to the health and welfare of its citizens. The past year was a shock to the U.S.
