Night Visiom

The night vision abilities of nocturnal animals such as mice is down to the unconventional way that DNA is packaged within the nuclei of specialised cells responsible for low-light vision, say Cambridge University researchers. The research shows that a special DNA architecture turns the rod cell nuclei into millions of tiny, light-collecting lenses. These lenses are stacked in columns which improve light transmission through the nocturnal retina and maintain vision, even at very dim light conditions.
