Historically, researchers have tested the safety and toxicity of chemicals by using biological assays, or bioassays. These tests involve exposing nonhuman animals—often rodents such as rats or mice—to ...

WASHINGTON— The Center for Biological Diversity filed a Freedom of Information Act request today seeking more information on a Trump administration plan to let polluters ignore rules limiting ...

Lurking within the genomes of nearly all species—including plants, fungi, and even humans—are genes that are passed from generation to generation with no clear benefit to the organism. Called "selfish ...

“The pesticide industry has conditioned Americans to believe the fiction that these highly toxic pesticides just magically vanish,” said Jess Tyler, a scientist at the Center for Biological Diversity.

Reducing exposure to toxic substances like cadmium and lead—found in cigarettes, polluted air, and contaminated food—could help slow biological aging and improve long-term health. These ...
