Air pollution may contribute to Alzheimer’s and dementia risk – here's what we're learning from brain scans

The tiny air pollutants known as PM2.5, emitted by vehicles, factories and power plants, aren’t just a hazard for lungs. A study finds more brain shrinkage in older women exposed to pollution.

Wildfire smoke changes dramatically as it ages, and that matters for downwind air quality – here's what we learned flying through smoke plumes

Thousands of chemical compounds in wildfire smoke are interacting with each other and sunlight as the smoke travels. For people downwind, it can become more toxic over time.
