- A Nature paper was shared showing that in-vivo base editing rescued Hutchinson–Gilford progeria syndrome in mice, demonstrating a concrete gene-therapy success for a premature-aging disease.  
- Researchers published an epigenetic clock for living beluga whales based on biopsy dart samples, yielding age estimates of 11–27 years and opening the door to non-lethal age profiling in cetaceans.  
- Discussion of the “heartbeat hypothesis” (that total lifetime heartbeats are roughly constant across species) led to citation of a study in which digoxin-treated mice had slower heart rates and longer lifespans, though confounding factors prevented a firm causal claim.  
- A systematic-review link was posted asking whether exercise acts as a senolytic therapy, framing physical activity as a potential low-cost longevity intervention.  
- An upcoming 26 Feb 2021 webinar by the International Commission on the Clinical Use of Human Germline Genome Editing was announced, prompting debate over why the focus is limited to genetic disease rather than enhancement for the general population.  
- A $1,400 portable EDM (electrical-discharge machining) tap-removal machine was highlighted as an example of niche but powerful open-source-adjacent hardware that could be rented or replicated more cheaply.
