New research reveals how the speed of ocean currents and the shape of the seabed influence the amount of heat flowing underneath Antarctic ice shelves, contributing to melting.

Scientists at the University of East Anglia (UEA) used an autonomous underwater vehicle to survey beneath the Dotson Ice Shelf in the Amundsen Sea, an area of rapid glacial ice loss largely due to increasing ocean heat around and below ice shelves.

With natural disasters striking communities across the U.S. at an accelerating pace, the question of how to build homes that can endure them has never been more critical. New research spanning political science and civil engineering shows that the answer could lie at the intersection of smarter regulatory systems and stronger structures. University of Notre Dame political scientist Susan Ostermann and her team have identified the building code features that have the biggest impact on hazard resilience and translated those features into tangible, practical building solutions.

For roughly two billion years of Earth’s early history, the atmosphere contained no oxygen, the essential ingredient required for complex life. Oxygen began building up during the period known as the Great Oxidation Event (GOE), but when and how it first entered the oceans has remained uncertain.

A new study published in Nature Communications shows that oxygen was absorbed from the atmosphere into the shallow oceans within just a few million years—a geological blink of an eye. Led by researchers at Woods Hole Oceanographic Institution (WHOI), the work provides new insight into one of the most important environmental shifts in Earth’s history.

A new University of Maryland study of campus air samples revealed that chemical compounds from Canada’s historic 2023 fires lingered in the air, forming an ‘atmospheric soup.’
