Air pollution contributes to nearly 7 million premature deaths each year, and its effects go far beyond the lungs. Breathing in wildfire smoke or automobile-related city smog doesn't just increase the risk of asthma and heart disease -- it may also contribute to brain conditions as diverse as Alzheimer's and autism. Scientists have discovered how a chemical change in the brain -- which can be triggered by inflammation and aging as well as toxins found in air pollution, pesticides, wildfire smoke and processed meats -- disrupts normal brain cell function. Known as S-nitrosylation, this chemical change prevents brain cells from making new connections and ultimately results in cellular death, the team discovered.

Microscopic plastic pollutants drifting through the air are lodging in the lungs of birds, a new study finds. Researchers worldwide are increasingly alarmed by how pervasive these harmful particles are in the air humans breathe and the food they eat.

Researchers have developed a new technique to make glass water-repellent, a feature that could improve safety in vehicles, reduce cleaning costs for buildings and enhance filtration systems. The research shows how an innovative and non-toxic process using ultrasonic sound waves can alter the surface of glass, making it either hydrophobic (water resistant) or electrically charged.
