Latest Photoreceptor cells Stories
Research lead by Dr. Nicolas Bazan, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans
The eyes of nocturnal mammals have very large numbers of highly-sensitive rod photoreceptors (the cell type responsible for night vision). They have to perceive light which is less than a millionth of the intensity of daylight
German-led scientists say they have discovered an important element of DNA that creates good night vision in nocturnal mammals. Ludwig-Maximilians University researchers in Munich said they discovered the DNA within the photoreceptor rod cells responsible for low light vision turns the rod cell nuclei themselves into tiny light-collecting lenses, with millions of them in every nocturnal eye. The conventional architecture seen in almost all nuclei is invariably present in the rod cells of...
Among zebrafish, the eyes have it. Inside them is a mosaic of light-sensitive cells whose structure and functions are nearly identical to those of humans.
A layer of "dark cells" in the retina that is responsible for maintaining the health of the light-sensing cells in our eyes has been imaged in a living retina for the first time.
A team of Johns Hopkins neuroscientists has worked out how some newly discovered light sensors in the eye detect light and communicate with the brain.
Researchers unravel how the very first eyes in evolution might have worked and how they guide the swimming of marine plankton towards light.
The Olympic athletes have been parading around like fashionistas in an array of colorful outfits, and we, their adoring public, can't resist commenting on the style and color of their high-end athletic wear.
Not so long ago, before electric lights, farmers relied on moonlight to harvest autumn crops. With everything ripening at once, there was too much work to to do to stop at sundown. A bright full moon -- a "Harvest Moon" -- allowed work to continue into the night.
