Prehistoric Rock in Japan Reveals Clues to Ocean Extinction Event
New analysis pinpoints timing and duration of extreme environmental disruption that choked oxygen from Earth’s oceans By studying prehistoric rocks and fossils emerging from the side of Mount Ashibetsu in Japan, researchers have precisely refined the timing and duration of Ocean...
Testing Limestone’s Ability to Capture Carbon From Air
Northwestern’s DOE-funded project will kick off in January 2025 at a farm in downstate Illinois A Northwestern University-led team of interdisciplinary researchers has received $5.1 million from the U.S. Department of Energy (DOE) to test the efficacy of enhanced weathering, a...
Stability of Perovskite Solar Cells Tripled with Protective Coating
Coated cells also delivered a solar power conversion efficiency of 26% Northwestern University scientists have developed a new protective coating that significantly extends the life of perovskite solar cells, making them more practical for applications outside the lab. Although perovskite solar cells...
Inverted perovskite solar cell breaks 25% efficiency record
Researchers improve cell efficiency using a combination of molecules to address different issues Northwestern University researchers have raised the standards again for perovskite solar cells with a new development that helped the emerging technology hit new records for efficiency. The findings, published in...
Greenland’s glacier retreat rate has doubled over past two decades
The new findings are ubiquitous, even among Earth’s northernmost glaciers Greenland’s thousands of peripheral glaciers have entered a new and widespread state of rapid retreat, a Northwestern University and University of Copenhagen study has found. To piece together the magnitude of glacier...
Behold the underwater caves of Yucatán, home to diverse microbial communities
New study constructs most extensive map yet of the cave system’s microbiome With help from an experienced underwater cave-diving team, Northwestern University researchers have constructed the most complete map to date of the microbial communities living in the submerged labyrinths beneath...
A bacterial enzyme converts greenhouse gas to liquid biofuel
A multidisciplinary study identifies the active site of Nature’s chosen enzyme for conversion of methane to methanol A team of researchers at Northwestern University have recently identified the active site in pMMO where methane is converted to methanol, a major stride...
Using humidity-powered technology, researchers found several new ions that facilitate low-energy carbon sequestration
Even as the world slowly begins to decarbonize industrial processes, achieving lower concentrations of atmospheric carbon requires technologies that remove existing carbon dioxide from the atmosphere — rather than just prevent the creation of it. Typical carbon capture catches CO2 directly...
Ancient plant wax reveals how global warming affects methane in Arctic lakes
Warming led to an intensified methane cycle, lasting thousands of years, study finds By studying fossils from ancient aquatic plants, Northwestern University and University of Wyoming (UW) researchers are gaining a better understanding of how methane produced in Arctic lakes might...
Electrifying heavy-duty vehicles could reduce environmental inequalities
New study examines air quality, health implications at equity-relevant geographic scales If the region surrounding Chicago — North America’s largest freight hub — shifted just 30% of its current on-road heavy-duty vehicles to electric versions, it would substantially reduce pollution and...
