Yoda The Mouse Turns 4

ChiralSoftware writes "Through some genetic engineering to reduce insulin output, Yoda the mouse has lived to over four years old, equivalent to 136 human years. Yoda is a third smaller than normal, and gets cold all the time so he must snuggle up with Princess Leia, his cage-mate, but he is alive and full of vigor at the ripe old age of 4. Who's next for insulin reduction?"

      There was an article in Sciam (August 2002 "The Serious Search for an Anti-Aging Pill") that discussed caloric restriction as a way to prolong life. Across the board, short-lifespan animals (fruit flys, rats, mice, hamsters, spiders, worms, etc), a reduced calorie diet extended the life span (both maximum and group average against the control). The researchers hypothesized that the reduced calories led to reduced sugar metabolism (lower insulin levels in the blood) and that the cells stayed in the Go phase (non-replicating state) as opposed to going through the cell cycle.

      Next, they tested a drug (2DG) that reduced the cells abilities to process glucose (a similar effect to having lowered insulin levels). At the time of the writing, they were in the middle of rodent testing on whether or not it produced longer lifespans.

      I suspect that Yoda, with his lowered insulin levels, does basically the same thing. His caloric intake is essentially reduced, lowering his metabolism (thus the smaller growth, problem with maintaining high body temp). Very interesting.

      This is true in most cases. One exception to the rule that i know of is with birds. Avian metabolism (particularly that of Parrots) is closely being studied for breaking the generalized paradigm of higher metabolism or faster heart-rate means shorter lifespan.

But very large numbers of larger parrots (such as Macaws) live well into their 80s and 90s, some past 100. Medium sized parrots (such as Conures or Cockatoos) can live 40 to 70 years. And even small parrots (love birds, parrotlets, cockatiels, etc.) can live up to 30 or more years if cared for properly.

      They do this and still have two to four times the resting heart-rate of humans. Also, humans have all kinds of fancy technology to keep them alive. Most of the longer-lived domesticated parrots were around even when Avian medicine was poor... and today, although avian medicine is much better, is not anywhere near is sophisticated as for humans, obviously.
