The new model mimics the structure and function of the human conjunctiva in a lab dish, even producing its own tears.

If evolution occurs through gradations, the critics say, how could it have created the separate parts of the eye -- the lens, the retina, the pupil, and so forth -- since none of these structures ...

Many scientists believed the same thing when the Eye of the Sahara was first spotted from space in the mid-'60s.) Visit Atlas Obscura for more on the Richat Structure.

The complexity of the anatomy of the eye is immense, and despite being considered a well-understood structure, newer knowledge about it keeps surfacing during ongoing research.

The system contains a sensor, chip and tiny AI model inspired by biological eyes and brains and uses a tenth of the energy of a camera-based system.

Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a study published August 12 in the journal Cell ...

How the 3-D structure of eye-lens proteins is formed Date: February 10, 2021 Source: Goethe University Frankfurt Summary: Chemical bonds within the eye-lens protein gamma-B crystallin hold the ...

The eye is a complex and delicate mechanism. Knowing the parts of the eye and how they work will help you recognize vision problems or eye health concerns early. This way, you can prevent long ...

This being so, a group of researchers at Moorfields Eye Hospital in London, working with others around the world, decided to study the structure of the eye for signs of cognitive decline.

These results could be well reproduced by a simple model. “The measured spectra of the bull’s-eye structure look complicated at first sight,” notes Tokizane. “However, our model describes the ...
