No improvement in life expectancy from a 25 year study on caloric restriction. Derek Lowe asks a good question:
Note that line about "benefits". The problem is, as far as I can see (Nature's site is down as I write), the two groups of monkeys appear to have shown the same broad trends in cardiovascular disease.

But, I'm sure bloggers and Twitter users will disagree.
