Most of us associate echolocation with bats. These amazing creatures are able to chirp at frequencies beyond the limit of our hearing, and they use the reflected sound to map the world around them. It ...

[Kripthor] suspected that hunters were getting too near his house. When thinking of a way to quantify this belief he set out to build a triangulation system based on the sound of gunshots. The theory ...

Add Yahoo as a preferred source to see more of our stories on Google. A pod of bottlenose dolphins (Tursiops truncatus) swimming at the Las Cuevitas dive site in the Revillagigedo Archipelago. We ...

For years, a small number of people who are blind have used echolocation, by making a clicking sound with their mouths and listening for the reflection of the sound to judge their surroundings. Now, ...

The discovery of a remarkably well-preserved fossil representing the most primitive bat species known to date demonstrates that the animals evolved the ability to fly before they could echolocate. The ...

Researchers are advancing robotics with bat-inspired echolocation drones for GPS-denied environments and humanoids capable of ...

Echolocation lets animals use sound as a guide in places where vision fails. They send out clicks, chirps, or taps and interpret the returning echoes to find prey, avoid danger, or move confidently in ...

All animals use a combination of senses to survive. But where the majority typically rely on one or two especially sensitive sensory systems, the oilbird excels by apparently having keen senses ...

Humans, when you train them, can be phenomenally good at pattern recognition. Our long history as the descendants of organisms who could spot a predator in dappled grass probably has something to do ...

Imagine you're an echolocating bat. You zip through the darkness with only your ears to guide you. You "see" tree trunks and branches by constantly emitting ultrasonic chirps, which bounce off objects ...

Scientists have figured out why bats crash into buildings: smooth, vertical surfaces like window panes throw off their navigation systems, basically keeping them from “seeing” those obstacles. The ...
