Glowing contact lens could prevent a leading cause of blindness
Hundreds of millions of people suffer from diabetes worldwide, putting them at risk for a creeping blindness, or diabetic retinopathy, that comes with the disease in its more advanced stages. Existing treatments, though effective, ...

Machine learning predicts behavior of stainless steel at the microstructural level
To the naked eye, a sheet of stainless steel presents a smooth, polished, homogenous surface. The same material when viewed at 400 times magnification reveals its true jumbled structure—different crystal shapes, joined ...

Using AI to detect seemingly perfect deep-fake videos
One year ago, Maneesh Agrawala of Stanford helped develop a lip-sync technology that allowed video editors to almost undetectably modify speakers' words. The tool could seamlessly insert words that a person never said, even ...

Cracking the da Vinci chronology: System tries to bring order to the works of a Renaissance genius
Leonardo da Vinci may have been a genius, but he was also a hot mess—at least in terms of organizing his works. When he died in 1519, the Renaissance master left behind 7,000 pages of undated drawings, scientific observations ...

Eye
Eyes are organs that detect light, and send signals along the optic nerve to the visual and other areas of the brain[citation needed]. Complex optical systems with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in cnidaria, molluscs, chordates, annelids and arthropods.
The simplest "eyes", such as those in unicellular organisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment.
