Death in the Dirt

Long-lived in the petri dish, mutant worms bite the dust in soil

Mitch Leslie

Abstract: Lab life is sweet for the average nematode, but it's particularly congenial for some mutant worms. Luxuriating on a comfy bed of agar and feasting on bacteria, the creatures can survive more than twice as long as nonmutants. But new work suggests that the altered worms falter in the wild. Mutants that live unusually long in the lab die abruptly when raised in soil. The findings add to the evidence that organisms can't get extra time for free.
