Lower Calorie Longevity

While we've "known" that lower calorie intake is linked to longer lives, the reason has eluded us for some time. Researchers have, however, found a gene in worms that plays a role in the mysterious process. Before this, researchers thought the longevity mechanism was controlled by an insulin signaling pathway. However, by screening a set of genes, they found that by removing the gene pha-4, the effect of a longer life would be completely removed by lower caloric intake.
Ultimately, the article provides a very interesting look into that oh-so-hot field of eluding death. Interesting also to see the inverse relationship between "quality" and "quantity". Could lead to some interesting drugs that allow us to consume what we want without the detrimental effects of that increased metabolism.
