Discover how scientists and doctors used bats' ultrasound capabilities as inspiration for SONAR and non-invasive medical procedures. In a dark cave, bats can t see much. But even with their eyes shut, they can navigate rocky topography at incredible speeds. This is because bats aren't just guided by their eyes, but rather, by their ears. It may seem impossible to see with sound, but bats, naval officers, and doctors do it all the time. How is that possible? Jacques S. Abramowicz digs into the unique properties of ultrasound

What are the advantages of ultrasound?
They're generally painless and don't require needles, shots or cuts.
You aren't exposed to ionizing radiation, so the procedure is safer than X-rays and CT scans.
Ultrasound captures images of soft tissues that don't show up well on X-rays.
Ultrasounds are widely accessible and less expensive than other methods.

My mom does ultrasound, so it s nice that they re talking about it. So few people actually know what ultrasound is other than it has something to do with babies in the womb and bats.

Hi Ted Ed, I love your videos, and share them. They are really helpful and interesting. Could you please do a video on 'surrealism' next? Looking forward to hearing from you.
