...its proboscis. Even though the infection is not fatal to the newts, it could affect their numbers, says Raffel . "When newts get infected, they often stop breeding, apparently to shore up their immune system to fight off the disease. But that comes at the cost of having fewer offspring," he adds. Fin...

Glucose triggers brain cell death in rats after hypoglycemic coma
