They also tend to have pupils that open more widely in low light. So, at the outset, nocturnal eyes gather more light than human eyes do. After the light passes through the pupil, it is focused by ...
MIT engineers have made a breakthrough in this area—they’ve developed a method to grow muscle tissue that contracts in ...
Human eyes are actually spheres. The part that we can see is only just the front. That coloured circle is called the iris and the black spot in the middle is the pupil. This is the part of the eye ...
Researchers were able observe eye movements during sleep over a course of several hours for the first time. Pupil size also fluctuates constantly during sleep, and is linked to the level of brain ...
