Scientists have compiled the most complete genome ever of the Greenland shark, an exceptionally long-lived species. Living up to 400 years probably has a lot to do with superior DNA repair mechanisms. Methuselahs of the sea Greenland sharks, giant, slow-moving abyss dwellers, hold the title of the longest-lived vertebrate. While estimating a wild species’ maximum...

The researchers of a previous controversial paper on the naked mole-rat's impressive longevity have returned, publishing data in GeroScience that bolsters their original findings. A darling of longevity The naked mole-rat, an unusually long-lived rodent species that lives in large colonies, has long been a mystery of gerontology, and investigations into its biology have yielded...

The quest for eternal youth, encapsulated in Dr. Malcolm's fictional yet profound declaration that "Life finds a way," mirrors humanity's age-old fascination with longevity. This fascination isn't new; as Nicolas Brendborg's "Jellyfish Age Backwards – Nature's Secrets to Longevity" expounds; it's as ancient as the epic tales of Ponce de Leon's mythical fountain of life...

Researchers have analyzed the activity of genes in the livers, kidneys, and brains of over a hundred mammals and found genes that are consistently associated with longevity [1]. The search for longevity-associated genes Between the shortest-living and the longest-living mammal, there is a more than 100-fold difference in lifespan. This natural difference may be key...

Researchers publishing in npj regenerative medicine have found that destroying senescent cells through a well-known senolytic combination gives older killifish back some of their regenerative abilities. Regeneration, for a while Killifish, like starfish and salamanders, are some of the most well-known regenerators of the animal kingdom, able to even regenerate brain tissue [1]. However, these...

Scientists have demonstrated that full-body regeneration in cnidarians, a group of animals that includes the jellyfish and hydra, can be driven by signals from senescent cells [1]. This might be the original purpose of cellular senescence. Why can’t we regrow our arms? There are many examples of amazing regenerative abilities in the animal kingdom, but...
