IN the past many investigations have been carried out on the static and dynamic reactions of the human pupil to illumination of the eye using white light. In this respect it seems surprising that ...

For the first time, researchers have been able to observe how the pupils react during sleep over a period of several hours. A look under the eyelids showed them that more happens in the brain during ...

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 ...

The condition may also be present from birth. Pupils, or the black parts at the center of the eyes, change size to regulate the amount of light entering the eye. Pupils are large in the dark to ...

MIT engineers developed a method to grow artificial muscle tissue that twitches and flexes in multiple, coordinated ...

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 ...
