In the eyes of mammals, visual information is processed on a daily schedule set within the eyes themselves–not one dictated by the brain, according to a new report in the journal Cell. The researchers found in mice that the eyes’ normal rhythmic response to light requires only that a molecular “clock” inside the retina go on ticking. The retina is a layer of nerve tissue covering the back of the eyeball, which is often likened to the film in a camera; without it, images can’t be captured.
Starving snakes employ novel survival strategies not seen before in vertebrates, according to research conducted by a University of Arkansas biologist. These findings could be used in conservation strategies to determine the health of snake populations.
The giant panda is not at an “evolutionary dead end” and could have a long term viable future, according to new research involving scientists from Cardiff University.
