For decades, people have been searching for the proverbial fountain of youth, and now some researchers are focusing on an ugly Mole Rat, who at 39 years old has outlived his counterparts by a multiple of five times. One researcher believes a factor may be that Mole Rats live underground, in dark tunnels away from the sun, and lack Vitamin D. Google has launched a biotech spinoff called Calico Labs, which is focused on combating aging and age-related diseases. Hopefully, this old Mole Rat will give us some clues.
