Malfunctioning outer segments are linked to cone cell diseases and blindness. Previous studies have shown microRNAs (miRNAs)—noncoding RNAs that repress gene expression—are essential to normal cone ...

Thank your rods. This story originally appeared in Volume 24 of Road & Track. I’m not saying that the cone cells, which detect color, are prima donnas, but they are much less numerous ...

We can see about a million different colours Most humans are trichromats, which means our eyes have three different types of cone cells: red, green or blue, able to detect about 100 shades each.

Drag the slider to the left to see how an animal would see the same scene. Whereas human eyes contain three types of colour-detecting cells, called cones, dogs have just two. Their cone cells are ...

AI-powered research on one of the largest eye studies to date has created the most detailed maps of the retina ever produced.

Typically, our colour vision is trichromatic, meaning we have three types of cone cells in our eyes, blue, green and red, that respond to short, medium and long wavelengths of light. Each cone ...
