Researchers call for revisions to air-quality monitoring guidelines to consider the sources of emissions. Researchers at Scripps Institution of Oceanography at UC San Diego examining 14 years of hospital admissions data conclude that the fine particles in wildfire smoke can be several times more harmful to human respiratory health than […]

A proposed hybrid-electric plane could “eliminate aviation’s air pollution problem,” say MIT engineers. Proposed design could reduce nitrogen oxide emissions by 95 percent, a new study finds. At cruising altitude, airplanes emit a steady stream of nitrogen oxides into the atmosphere, where the chemicals can linger to produce ozone and […]

Iron-catalyzed [2+2] oligomerization of butadiene produces (1,n’-divinyl)oligocyclobutane, a new polymer that can be chemically recycled. Credit: Figure by Jonathan Darmon of the Princeton University Department of Chemistry New polybutadiene molecule enchains in squares, a microstructure that enables it to depolymerize under certain conditions, advancing options for closed-loop recycling. As the […]

Stanford researcher Ryan Searcy collects water samples from a tide pool at the Fitzgerald Marine Reserve, in Moss Beach, California. Credit: Meghan Shea Using water samples and environmental data gathered over 48 hours or less, Stanford engineers develop a new predictive technique for forecasting coastal water quality, a critical step […]

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago — and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming — both past and […]

This InEnTec plant in Oregon will receive feedstock materials, such as medical and industrial waste, and — using InEnTec’s plasma gasification process — will convert them into high-purity hydrogen for use in industry and fuel cell vehicles.

Corals in the Gulf of Aqaba in the Red Sea. Credit: Maoz Fine A paper to be published in Frontiers in Marine Science on December 15 is calling for action to remove the oil from a decaying and inactive tanker in the Red Sea that holds approximately one million barrels of oil […]

The Gibson Generating Station is a coal-burning power plant located in Gibson County, Indiana. Credit: Emily Grubert, Georgia Tech Decarbonizing U.S. electricity production will require both construction of renewable energy sources and retirement of power plants now operated by fossil fuels. A generator-level model described in the December 4, 2020, […]
