Two major groups of bats that use echolocation have different structures for connecting the inner ear to the brain, according to a new study by researchers from the University of Chicago, the American ...

Lots of bats echolocate-- they emit high-pitched squeaks, and based on how those sound waves bounce off their surroundings, they're able to navigate in the dark and find insects to eat. But a lot ...

Autoimmune inner ear disease (AIED) is a complex condition in which the immune system aberrantly targets inner ear structures, leading to a fluctuating and often progressive sensorineural hearing loss ...

Warm-bloodedness is a key mammal trait, but it's been a mystery when our ancestors evolved it. A new study points to an unlikely source for telling a fossil animal's body temperature: the size of tiny ...

Hot or not? Peeking inside an animal’s ear — even a fossilized one — may tell you whether it was warm- or cold-blooded. Using a novel method that analyzes the size and shape of the inner ear canals, ...

The research, published this week in Nature, provides the first anatomical evidence of two distinctive inner ear structures used for processing bats’ echolocation signals. The study confirms ...

A new article compares the inner ear structures of the two main groups of bats. By examining the microscopic inner ears of bats from 19 of the 21 known bat families, the researchers were able to show ...
