Study finds the bug-repellent ingredient stopped an enzyme from doing its job

DEET, the active ingredient in many bug repellents, doesn’t only cripple mosquitoes — it also meddles with mammals. A new study examining DEET’s effects on insects, mice and human proteins reports that the chemical interferes with a prominent central nervous system enzyme.

The results are consistent with previous studies, says Bahie Abou-Donia of...
