In contrast, maple leaves survive for only one season, while blueberry leaves have a lifespan of a mere three months. So, what determines the lifespan of a tree leaf? The answer to that superficially simple question is reported today in a paper inScience Advancesby an international team of...

Over the tree's lifespan it grows into a large pyramidal shape. As the tree ages, the upper canopy becomes flat and slightly irregular. A monoecious tree, the Norway spruce has the capability of self-pollination by producing both male and female flowers, according to the Ohio Department of ...
the effects of one of these alternative strategies, notably increasing fine‐root mass, on the tree's net C gain (used here as a proxy for tree performance), and to assess how fine‐root lifespan influences the relative importance of SRL and fine‐root mass for the C balance of trees. ...

Pharmacological attenuation of mTOR presents a promising route for delay of age-related disease. Here we show that treatment of Drosophila with the mTOR inhibitor rapamycin extends lifespan in females, but not in males. Female-specific, age-related gut p
