New research describes the mechanism behind catalysis that neutralizes air-polluting NOx from power plant emissions. Researchers used a High Field (HF) Nuclear Magnetic Resonance (NMR) spectrometer in conjunction with reaction studies to test three theories around titania-supported vanadium oxide. They found that tungsten oxide changes the structure of vanadium oxide from a less active form to a highly active form.

Nitrogen from agricultural production is a major cause of pollution in the Mississippi River Basin and contributes to large dead zones in the Gulf of Mexico. Illinois and other Midwestern states have set goals to reduce nitrogen load through strategies that include different land management practices. A new study uses computer modeling to estimate how those practices may be affected by potential changes in the climate, such as increased rainfall.

Greenhouse gases may get more attention, but aerosols — from car exhaust to volcanic eruptions — also have a major impact on the Earth's climate. Using a massive NASA dataset, researchers have created a framework that helps explain just how sensitive local temperatures are to aerosols.

When clouds loft tropical air masses higher in the atmosphere, that air can carry up gases that form into tiny particles, starting a process that may end up brightening lower-level clouds, according to a new study. Clouds alter Earth's radiative balance, and ultimately climate, depending on how bright they are. The new paper describes a process that may occur over 40% of the Earth's surface.

Breathing dirty air can make you sick. But according to new research, it can also make you more aggressive. That's the conclusion from a set of studies recently authored by Colorado State University researchers. The team found strong links between short-term exposure to air pollution and aggressive behavior, in the form of aggravated assaults and other violent crimes across the continental United States.

A new study is the first to report evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin may lessen the adverse effects of air pollution exposure on lung function. The researchers found that the use of any NSAID nearly halved of the effect of PM on lung function, with the association consistent across all four weekly air pollution measurements from same-day to 28 days prior to the lung function test.
