The newly discovered cells are shaped like twisted tree branches and were found deep inside the retina of a rat's eye. Like the eye's rods and cones, the new cells contain chemicals that react to ...

Scientists have discovered a 300-million-year-old fossil of a fish species called Acanthodes bridgei. The presence of rod and cone cells in the eyes suggests that the fish had color vision.

Rods and cones are found in the retina of the human eye. The rods -- some 120 million -- are more sensitive than the cones, but are not sensitive to color.

Cone-rod dystrophy is a group of IRDs that damage cones and rods. Vision loss gets worse over time. Between 1 in 30,000 and 1 in 40,000 people have cone-rod dystrophy.

Scientists have discovered a fossilized fish so well preserved that the rods and cones in its 300-million-year-old eyeballs are still visible under a scanning electron microscope.

The eye (and the fish that hosts it) was discovered in Kansas, but it is currently housed in the National Museum of Nature and Science in Tokyo. These ancient rods and cones helped a type of fish ...
