...interpretation can't account for the fact that the pupils of mammals with no functional rods and cones still open wider in dim light and get smaller in bright light," Van Gelder explains.

The pupils of "rod-less/cone-less" mice got just as small, but in mice without melanopsin, the smallest attainable size was three times larger than in other mice, the researchers found. Importantly, they also proved that, even without melanopsin, retinal gang...Scientist says recent UNC research suggests better nerve agent treatment

In experiments at the University of Toronto, co-author Nicholas Mrosovsky discovered that the triple knockouts also didn't appropriately adjust their activity levels when exposed to light.
