* Hydra (Hydra vulgaris): small freshwater animals which show no signs of aging when protected from predators and disease. They maintain their ability to regenerate cells and avoid cellular deterioration through continuous renewal of their stem cells.
* Immortal Jellyfish (Turritopsis dohrnii): can revert to an earlier life stage when stressed, avoiding death from aging indefinitely by cycling between adult and polyp stages.
* Planarian Flatworms: can regenerate their entire bodies from small pieces and show no signs of aging due to a large population of stem cells called neoblasts.
People should probably also learn why certain closely-related species have such different lifespans. Here are some:
* Calico rockfish (S. dallii) and Halfbanded rockfish (S. semicinctus) appear to only live 15-20 years while Rougheye rockfish (Sebastes aleutianus) live 200 years or more.
* among bivalve ocean creatures, Eastern oysters (Crassostrea virginica) live about 5-10 years and Common mussels (Mytilus edulis) about 20-25, while Hard-shell clams (Arctica islandica) live over 500 years.
Humans need to learn the biological secrets of such creatures, such as by studying their genomes and mechanisms of negligible or even reversed senescence. Then we need to apply such knowledge to ourselves.
Two obvious techniques for this are: (1) using the new CRISPR Cas9 technology to rewrite the human genetic code; and (2) using the old method of gene therapy thru viral vectors to do the same. Both techniques can potentially enhance human longevity via direct genetic manipulation.
The
world needs scientific, medical, and healthcare geniuses to work on
this. The word needs new iterations of Leonardo Da Vinci and Albert
Einstein to work on the theoretical and idea side of this issue; and
new iterations of Thomas Edison and Steve Jobs to work on the
practical and effective
side.
The planet needs to shun government funding or
communist
research and development on
this. It needs to
strictly avoid having the state “throw money at the problem” and
utilizing
versions of the Post Office and DMV to
enhance human longevity.
This won’t just be ineffective and useless; it will slow down,
stop, or reverse progress by diverting scarce
money, knowledge,
energy, enthusiasm, and publicity from competent researchers and
developers.
To
defeat mankind’s worst enemy, the Grim Reaper, there is a desperate
need to work on this problem immediately. Many billions of dollars
and thousands of scientists
and doctors are
currently working on
this problem, but there
needs to be far more.
