Professor Discovers New Human Body Part

Get ready to put your hands together and give a warm welcome to the newest addition to the human anatomy. Introducing: Dua’s layer.

The new ocular part, which sits at the back of the cornea, was discovered by Harminder Dua, a professor of ophthalmology at the University of Nottingham. It's only 15 microns thick, but the discovery, per Dua, has big implications.

Before, researchers were aware of five corneal layers. But, thanks to the help of an electron microscope, Dua and his colleagues were able to discover this additional one by injecting air bubbles into the cornea to separate its layers.
