Popular aquarium fish provides a window on environmental chemicals

On average, an individual encounters about 80,000 synthetic chemicals every day. So says Robert Tanguay, a toxicologist at Oregon State University. Many of those chemicals — from fire retardants in fabrics to drying agents in paint — are untested for toxicity to people. Tanguay and his research team are working to change that. Their results […]

Regulating Immunity: Toxicologists seek novel gene therapies

Dioxin, the chemical pollutant made infamous by Vietnam-era defoliant Agent Orange, has long been known to suppress immune function in humans and other animals. Surprisingly, this dangerous side effect has a scientific silver lining. While studying the toxin’s health effects, researchers discovered the genetic pathway to immune system malfunction. For people who would actually benefit […]

Saili, who grew up in Kalispell, Montana, studies the effect of nanomaterials on inflammation. She uses transgenic zebrafish whose white blood cells fluoresce […]
