A genetically engineered organism that lives 10 times longer than normal has been created by scientists in California.
(They deleted two genes and put the organism on a calorie-restricted diet. If scientists could apply this DNA tweak to humans it would mean we'd live to over 800 years old. Of course it's probably a long way off, the organism in question was a fungus, and apart from a couple of men I know, this wouldn't be easy to transfer to humans.)
