Discovery of Gene That Affects Lifespan Could Have Big Impact

Scientists have discovered a gene that could lead to longer, healthier lives. For decades, scientists have known that a low-calorie diet leads to lifespan increases up to 40 percent in various species -- from worms to primates. Now, researchers from the Salk Institute have discovered why this phenomenon is happening. Lead researcher Andrew Dillin says the gene discovery could yield new drugs that would allow people to reap the health benefits without adhering to a strict diet.
