Roundworms, also known as nematodes, live longer in colder temperatures. According to new research from the University of Michigan, this is because cold air acts as a trigger for a gene receptor -- TRPA-1 -- that, once triggered, sets off a chain of reactions that culminates in the activation of a gene known to be tied to longevity.
