A new study has found that serotonin and TGF-beta hormone levels in specific neurons of C. elegans communicate information about food abundance in roundworms. These signals from the nervous system influence the animal's lifespan, thus mediating the effects of food on ageing.

Geochemists report that photosynthesis leaves behind a unique calling card in the form of a chemical signature that is spelled out with stable oxygen isotopes. The findings suggest that similar isotopic signatures could exist for many biological processes, including some that are difficult to observe with current tools.
