Mar. 14, 2023 A research team demonstrates that increased levels of ozone resulting from anthropogenic air pollution can degrade insect sex pheromones, which are crucial mating signals, and thus prevent successful ...
Mar. 10, 2023 New evidence shows that exceeding the World Health Organization (WHO) ozone limit is associated with substantial increases in hospital admissions for heart attack, heart failure and stroke. Even ...
Mar. 8, 2023 A new study finds that smoke particles in the stratosphere can trigger chemical reactions that erode the ozone layer -- and that smoke particles from Australian wildfires widened the ozone hole by 10 ...
Feb. 14, 2023 Researchers have summarized the threats that future rocket launches would pose to Earth's protective ozone ...
Jan. 18, 2023 Long-term measurements in the urban area of Innsbruck, Austria, show that the fraction of ozone near the surface tends to be overestimated in atmospheric models. Consequently, a fundamental ...
Dec. 9, 2022 Assuring that a growing global population has access to clean water will require new water treatment methods. One of these next-generation methods involves a form of iron called ferrate, which ...
Dec. 7, 2022 When winter chill strikes, people stay indoors more often, giving airborne pathogens -- such as SARS-CoV-2 and influenza -- prime opportunities to spread. Germicidal ultraviolet (GUV) lamps can help ...
