Knowledge is a constant thing. Without its constant cycle, the human minds would never evolve and new things wouldn't be discovered.

The new body part that was discovered by the University of Nottingham scientist is the perfect example of this. Professor Harminder Dua discovered a new layer in the cornea — the clear dome of tissue that covers the pupil and iris. There were only 5 layers previously but now the newly discovered sixth layer is now called Dua's layer.

This new discovery might be petty for most people, five-six, what's the difference right? However, this discovery gave way to plenty of opportunities, especially when it comes to eye treatments. Hopefully, they can make use of this opportunity fully.
