Bed bugs are but one example of a species whose populations have evolved in response to human behavior.

William Briggs’s theory of optic nerve architecture was unusual and incorrect, but years later it led to Isaac Newton’s explanation of binocular vision.

A handful of stem cell therapeutics for vision disorders are showing promise in early-stage trials, and still more are in development. But there’s a long road to travel before patients see real benefit.

Vision researcher John Dowling has spent a lifetime studying the neural architecture of the retina. He is closing his laboratory after 53 years, opting to extend these studies as a postdoc.

Sounds trigger a response in the visual cortex that predicts how accurately a person can identify a visual target.

In mice, adult cone cell outer segments and their visual functions deteriorate if two microRNAs are not present.

Retinal glial cells acting as optical fibers shuttle longer wavelengths of light to individual cones.

Scientists adapt an in vivo retina recorder for ex vivo use.

Researchers are beginning to study in depth the largely uncharted territory of the eye’s microbial composition.

Scientists are beginning to embrace social media as a viable means of communicating with public audiences.

Extinct, giant arthropods, long assumed to be top predators of ancient seas, didn’t have sharp enough eyesight to be refined hunters.

New software that can trace the individual paths of every animal in a massive swarm could help biologists unravel the secrets of collective behavior.

Despite a lack of vision, a blind cavefish can count. Sort of.

Retrieving sound from video recordings of inanimate objects can have surprising applications.
