The “Surprising” Effect of Drying Headwaters on Nitrogen Dynamics

by Saima May Sidik 15 April 202515 April 2025

Contrary to predictions, spring rains caused a decrease in nitrogen at watershed outflows in Alabama.

A satellite image of the border between Türkiye and Syria is marked with multicolored waves. The magnitude 7.8 mainshock is marked on the map, and a scale at the bottom shows the interferometric phase in radians from −3.14 to 3.14.

Türkiye-Syria Temblors Reveal Missing Piece in Earthquake Physics

by Aaron Sidder 15 April 202515 April 2025

Newly discovered aseismic events triggered by the 2023 Kahramanmaraş earthquake may represent a mode of fault slip between earthquakes and slow-slip events that researchers have long been seeking.

Dozens of ice cores—long, thin cylinders—are stored on a metal shelf and seen from the front, so they look like circles.

When Ice Ages End, Ocean Circulation Fine-Tunes Ocean Heat

by Sarah Stanley 14 April 202514 April 2025

New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.

Four seemingly identical, octagonal, disklike structures, each with several various thin antennas extending outward at various angles, appear to be floating in a closely spaced cluster in space. In the background, on the right side of the image, is the round shape of the planet Earth, encircled by translucent, overlapping blue and purple lines.

“Thirstwaves” Are Growing More Common Across the United States

by Rebecca Owen 7 April 20257 April 2025

Like heat waves, these periods of high atmospheric demand for water can damage crops and ecosystems and increase pressure on water resources. New research shows they’re becoming more severe.
