In Memoriam
FT member ARR_309 first mentioned "genomic memory" in influenza and I keep wondering about it. In this article, it's a simple organism with inherited epigenetic changes, which they claim disappear after a few generations. ARR's "genomic memory" in influenza would have to survive longer.

Long life can be passed to the worms' offspring via changes in the way genes are used, rather than the genes themselves
Long-lived worms can transmit their extended lifespan to the next generation by passing on changes in the way their genes are used, rather than differences in DNA itself.
A study has shown that nematode worms can inherit a "memory of longevity" from their parents, even though their genome remains unchanged.
It is not clear if the same processes apply to humans.....
