Credit: Unsplash/CC0 Public Domain Greater buffer zones around bodies of water and more consistent enforcement of water protection regulations are needed to reduce agriculture-based pollution in the Western U.S., a recent review from Oregon State University found. Prior research has shown that agricultural pollution, both from croplands and rangelands, is the […]

Global map reveals areas at risk of pesticide pollution. Credit: Associate Professor Federico Maggi, Dr. Fiona Tang, University of Sydney ENLARGE Global Pesticide Use Is Set to Increase A global map of agricultural land across 168 countries has revealed that 64 percent of land used for agriculture and food […]
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 […]
WEST CUMBRIA MINING COMPANY Britain’s climate change leadership is being undercut by a government decision to allow a new coal mine in Cumbria, MPs have warned. The UK is hosting a UN climate summit in November, where it will urge other nations to phase out fossil fuels. The MPs say […]
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.
