Silencing genes — to understand them
Hijacking a cell process called RNA interference can let scientists turn off a selected gene. Its silencing can point to what genes do when they’re on — and may lead to new treatments for disease.

Air pollution can mess with our DNA
New research suggests a type of air pollution — diesel fumes — can affect your health. It inappropriately switches some genes on, while turning off others.
