Scientists at USC and Caltech, in collaboration with startup company Calcarea, have developed a promising shipboard system that could remove up to half of carbon dioxide emitted from shipping vessels by converting it into an ocean-safe solution.

A dataset unveiled today more than doubles the documented stream miles in the Chesapeake Bay Watershed, elevating the total from approximately 150,000 to nearly 350,000 miles. The novel, AI-supported mapping method dramatically reduces costs, time, and labor required for stream mapping, making it easy to update as additional data become available or apply in other watersheds to amplify its impact. The project is a collaboration between University of Maryland, Baltimore County (UMBC), the EPA’s Chesapeake Bay Program and the nonprofit Chesapeake Conservancy. 

A Dartmouth study uses machine learning to reexamine whether climate change is causing large waves in the polar jet stream that have brought Arctic-like temperatures and storms to temperate regions of the United States in recent years. The researchers constructed a timeline of the jet stream's wintertime variability since 1901 and found it's in the latest of several “wavy” periods from the past 125 years, most of which predate significant effects of climate change. The authors report that climate change is likely not amplifying extreme winter weather by making the jet stream wavier, but through more direct links such as a warmer atmosphere that retains more moisture.

A new study reveals that water-extractable organic matter (WEOM) from air-dried soils can effectively estimate microbial biomass, offering a safer alternative to traditional methods. This approach reduces the use of toxic solvents, simplifies sampling, and shows a strong correlation between WEOM and microbial biomass carbon. The findings open new doors for accessible and scalable soil microbiology research. This innovative method provides a safer, more efficient alternative to traditional chloroform fumigation extraction, enhancing soil microbiology research.

Black soils, revered as the world's agricultural powerhouses, are rapidly deteriorating under mounting environmental and human pressures. 

Research led by Earth scientists at the University of Southampton has uncovered evidence of rhythmic surges of molten mantle rock rising from deep within the Earth beneath Africa. These pulses are gradually tearing the continent apart and forming a new ocean.
