A Dwarf Mouse has become the world's oldest - after celebrating his fourth birthday. Yoda who lives in a lab at a university in Michigan, is 1.462 days old, the equivalent of about 136 human years. The lab's professor Richard Miller said: "The previous record holder in our colony died nine days short of his 4th birthday. Hundred-year-old people are much more common than 4-year-old mice". But Yoda, who lives with a mate named Princess Leia, has had some help. His pituary and thyroid glands were genetically modified to reduce his levels of insulin, helping him live longer.
