Calorie restriction Careful restriction of the number of calories eaten, without causing malnutrition, extends the lifespan of numerous organisms – from worms to mice – but whether it works in monkeys is controversial. Building on results from a long-running primate experiment, a team at the University of Wisconsin show a reduction in mortality, in response to caloric restriction. So there seem to be some benefits, but Tracey Logan asks if this can be applied to humans? And would we want to live longer on a tightly controlled diet?Dating the Moon New work by planetary scientists from France, Germany and the USA, has given the most accurate date yet for the birth of the moon. The Moon is believed to have formed out of debris from a massive collision with another Mars-sized planet. The date of this event has always been controversial as radioactive decay readings have produced wildly different results. But this clock uses a different approach, and rules out an early-forming moon. The later the moon formed, the
