Ginkgo biloba | vascular cambium | R-genes | flavonoids | 600 years no aging | Hiroshima survivor tree
A single ginkgo tree survived the 1923 Tokyo earthquake and the 1945 Hiroshima atomic bomb. Scientists discovered why — its cambium never stops dividing, its defense genes never go quiet, and its chemistry keeps cleaning the wood from the inside.
