Gene clues may explain why Brandt’s bat lives so long

Brandt’s bat (Myotis brandtii) typically weighs 4 to 8 grams – about half the weight of a house mouse. At that weight, a well-established link between body mass and lifespan dictates that it should live no more than five years. Yet in 2005, biologists captured a Brandt’s bat in Siberia 41 years after it had first been caught. A new study may have identified the genes behind its longevity. Image: Gilles San Martin
