On the #loss of #sensoryfunction as a sign of #aging in #animals, and #owls, which retain good hearing even in old age. The lives of many animals are limited by #agingprocesses that do not necessarily culminate in total organ failure. Long before that point, aging individuals simply become unable to survive because their #sensoryorgans increasingly fail to function. An animal that can no longer interact with others of its conspecifics, because it can no longer perceive them, will not survive long in a social group. Similarly, an animal unable to #smell, #see, or #hear its food will sooner or later #starve. However, researchers have now discovered that owls retain their most important sense, #hearing, well into old age. According to the authors, owls are capable of regenerating lost hair cells in the inner ear. © Stefan F. Wirth, August 2026, Berlin Reference:

Be jealous of barn owls: Even in old age, they don't lose their hearing, according to a 2017 study. This is because, unlike mammals, birds can regenerate lost hair cells in the innermost part of the ear that is responsible for detecting sounds, the scientists say. Understanding how birds retain good hearing, they add, may lead to new treatments for humans. Learn more this #OwlAwarenessDay: https://t.co/rJoh3S895t
