Researchers discover molecular light switch in photoreceptor cells

How our eyes detect and respond to changes in light intensity is determined by specialized cells in the eye called photoreceptors. In addition to converting light into electrical signals, effectively allowing us to see, rod-shaped ...

New type of visual filter discovered in an unlikely place

A University of Minnesota-led research team recently discovered a new way animals can modify their vision. Crystal-like structures in the photoreceptors of larval mantis shrimp simultaneously reflect and transmit light onto ...

Tracing the evolution of vision in fruit flies

The function of the visual photopigment rhodopsin and its action in the retina to facilitate vision is well understood. However, there remain questions about other biological functions of this family of proteins (opsins) ...

Nanotechnology makes it possible for mice to see in infrared

Mice with vision enhanced by nanotechnology were able to see infrared light as well as visible light, reports a study published February 28 in the journal Cell. A single injection of nanoparticles in the mice's eyes bestowed ...

Light-induced changes in photosensory proteins

Researchers from Charité - Universitätsmedizin Berlin have demonstrated on a molecular level how a specific protein allows light signals to be converted into cellular information. Their findings have broadened the understanding ...

Chemists discover how blue light speeds blindness

Blue light from digital devices and the sun transforms vital molecules in the eye's retina into cell killers, according to optical chemistry research at The University of Toledo.
