Electrical Pulses Rejuvenate Sea Squirts, Offering Insights Into Aging and Human Health

16 June 2026 11:10

A new study from UC San Diego and Stanford shows that brief electrical pulses significantly improve health and extend lifespan in sea squirts. - 75% of treated sea squirts survived a year vs.

20% of untreated ones. - The treatment triggers a gene expression reboot similar to exercise in humans.

- Sea squirts bridge invertebrate and vertebrate systems, aiding stem cell research. While human applications are distant, the findings offer insights into aging, exercise, and cellular repair.
