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. Lesson by Jacques S. Abramowicz, directed by Sofia Pashaei.

Dig into the science of how heart transplants happen, how donors are matched and find out how this complex surgery saves lives. -- Your heart beats more than 100,000 times a day. In just a minute, it pumps over five liters of blood throughout your body. But unlike skin and bones, the heart has a limited ability to repair itself. So if this organ is severely damaged, there’s often only one medical solution: replacing it. Roni Shanoada explores how this complex and intricate procedure works.

Explore the eye-opening science of LASIK: corrective laser eye surgery that focuses on reshaping the cornea to fix blurry vision. -- In 1948, Spanish ophthalmologist Jose Ignacio Barraquer Moner was fed up with glasses. He wanted a solution for blurry vision that fixed the eye itself, without relying on external aids. The surgery he eventually devised was called “keratomileusis,” and his technique focused on reshaping the cornea— what we now know as LASIK. So how does laser eye surgery actually work?
