Will the naked mole rat help humans live longer?

They may not be nature's loveliest creatures, but buck-toothed, long-lived naked mole rats may help scientists figure out how to make humans live longer and fight off cancers.

Scientists tell The Washington Post that they've managed to transcribe the underground creature's entire DNA sequence. They plan to comb the African rats' DNA for secrets to their 25-year lifespans--which are strikingly long for rats--and incredible resistance to developing cancerous tumors.
