(p. D2) . . . a January  study on ginkgo trees, which can live for over a thousand years . . . found that 600-year-old ginkgos are as reproductively and photosynthetically vigorous as their 20-year-old peers. Genetic analysis of the trees’ vascular cambium — a thin layer of cells that lies just underneath the bark, and creates new living tissue — showed “no evidence of senescence,” or cell death, the authors wrote.
