Air Pollution

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…

An old dog, it turns out, can teach humans new tricks. “In recent years the dog has grown to be one of the most important animals for researchers who aim to understand the biological background of complex traits,” says Eniko Kubinyi, an ethologist at Eötvös Loránd University in Budapest, Hungary.…

Air pollution in urban areas is linked to heightened risk of progressive and irreversible sight loss known as age-related macular degeneration (AMD), a major study of more than 52,000 people has found. AMD is the leading cause of irreversible blindness among over 50s in Ireland and in high-income countries –…

BEIJING - A Chinese central government inspection team has accused the country's energy administration of negligence in environmental protection, failing to control new coal power capacity in key polluted areas.

A new study examined whether federal policy aimed at mitigating local air pollution—specifically, the Clean Air Act—affected the municipal bond market from…

In a time-stratified, case-crossover study, exposure to both large and small particulate matter, as well as to nitrogen dioxide, was significantly associated with increased odds of death from myocardial infarction (MI). Investigators found "consistent evidence" that short-term exposure to particulate matter with an aerodynamic diameter of 2.5 μm or smaller (PM2.5),…

A green group said on Thursday that despite improvements in air quality amid Covid-19 outbreaks last year, pollution levels are still far exceeding the limits set by the government. Clean Air Network analysed data collected from both general and roadside monitoring stations set up by the government across the city,…
