Scientists are striving to unlock the genetic secrets of unusually long-lived animals to find clues to extending healthy human life.
The research spans species from hummingbirds to whales, and phenomena from cancer resistance to the management of immune system responses.
The work exploits advances in the analysis of DNA and other parts of cells to seek lessons from nature that could help extend human lifespans and years of wellness. It plays into growing interest from high-profile entrepreneurs, companies and even world leaders in improving longevity.
Last week China’s President Xi Jinping and Russian counterpart Vladimir Putin discussed the potential for big advances in human lifespans. A translator for Putin said continuous human organ transplants could help people “become younger” or even “immortal”, while Xi noted predictions that in this century people might live until age 150.
