A superpowered animal: the bat almost never develops cancer and its body is indestructible

1,200 mosquitoes in an hour. That is a bat’s hunting rate in the middle of the night, and it is only the most mundane fact about an animal that has been surprising science for 50 million years.

What makes the bat truly extraordinary is inside its body. Flying drives its metabolism to levels that in any other mammal would generate massive cellular damage from free radicals. They solved that millions of years ago: they developed total resistance to that damage, and that led to an immune system that makes them the only mammals that rarely develop cancer. Brandt’s bat, for example, can live up to 41 years. Its wings, with almost the same joints as a human hand, perform maneuvers that no drone has been able to replicate. And along the way, they pollinate bananas, mangoes, avocados, and agaves.

That is why scientists study them so closely: not as a threat, but as a model. What this animal solved through evolution could be the key that medicine has been seeking for decades. 🦇
