Scientists have good reasons to be curious about the genome of the naked mole-rat. The mole-rat, found in the deserts of East Africa, can survive many years in a harsh environment and appears to be resistant to diseases of aging, including cancer. Studies suggest that the mole-rat cells have anti-tumor characteristics not found in other rodents.
