1 day agoThese ants navigate with a compass tuned to the moon
Bull ants keep navigating after sunset using an innate lunar compass and time compensation based on elapsed time since leaving the nest.
Bats are impressive navigators. Like so many mini submarines equipped with sonar, they deftly navigate dark forests and caves by listening for the echoes of their own calls. But how bats can tell which echo to follow while flitting around in a sea of overlapping and competing signals pinging off the myriad surfaces in their environments has been a mysteryuntil now.
