Longevity in Brandt's Bat

The Brandt's bat is a species of bats that only weighs four to 8 grams as an adult. However, it can live to more than 40 years. Usually, small animals live short lives, however, this species says otherwise. This species of bat has the greatest disparity between its weight and longevity. Researchers became interested in this species and published an article revealing insights on the longevity of the bat. Through gene sequencing and genome comparison, specific sequence changes in the growth hormone (GH) and insulin-like growth factor 1 (IGF1) receptors along with their adaptations like hibernation and low reproductive rate are seen to contribute to the bat's longevity. On a molecular level, the altered sequences in the GH and IGF1 are only sequences seen (as of right now) to have the strongest relationship to longevity.

The fountain of youth, immortality, and extending life had always been a fascinating when I was growing up. Sure, immortality is still out of the question, but gene sequencing has brought aging under a whole new light. With genetics, the potential for slowing aging and extending life are now plausible. This research could lead to many revolutionary changes while also spring forth a whole variety of ethical concerns. Many issues that could be brought up may regard sustainability, the economy, and the future of aging. For future possible studies, a plan should be devised to use techniques based on gene regulation in order to extending life in other species of bat, or even other mammals.
