Vision changes in space

Understanding the effects of microgravity on the human body is essential in enabling astronauts to travel through the harsh environment of space for months, or even years. Significant changes to the body's skeletal and muscle ...

A beacon molecule that prevents vision, behavioral problems in mice

Nestled deep in the middle of the vertebrate brain is a multi-sensory integration and movement control center called the superior colliculus. In rodents, this brain region integrates multi-sensory inputs—visual cues, sounds, ...

Colorblind fish reveal how vision evolved

After decades of studying color vision in mice, new research in zebrafish has allowed experts at the University of Tokyo to uncover how some animals regulate their ability to see blue light. The results, published in Science ...

Primordial 'hyper-eye' discovered

An international research team has found an eye system in trilobites of the suborder Phacopina from the Devonian (390 million years ago) that is unique in the animal kingdom: each of the about 200 lenses of a hyper-facet ...

Researchers design technology that sees nerve cells fire

Scientists have plenty of ways to watch as individual neurons in a brain fire, sending electrical signals from one to the next, but they all share a basic problem. Each method, whether it involves electrical probes, chemical ...

Deep learning for glaucoma detection

Glaucoma is the second leading cause of blindness in the world, impacting approximately 2.7 million people in the U.S alone. It is a complex set of diseases and, if left untreated, can lead to blindness. It's a particularly ...

A new generation of artificial retinas based on 2-D materials

Scientists report they have successfully developed and tested the world's first ultrathin artificial retina that could vastly improve on existing implantable visualization technology for the blind. The flexible device, based ...
