UV-sensing protein in the brain of a marine annelid zooplankton

Researchers at Institute for Molecular Sciences reported that a photoreceptive protein expressed in the brain a marine annelid zooplankton (Platynereis dumerilii) is UV-sensitive. This work was carried out as a collaborative ...

A first glimpse into disc shedding in the human eye

An elusive biological cycle in the eye - the daily disposal and regeneration of the end tips of photoreceptor cells - has been captured in images for the first time in a living human eye. Photoreceptors are light-sensitive ...

Team identifies a form of congenital night blindness in dogs

People with congenital stationary night blindness, or CSNB, have normal vision during the day but find it difficult or impossible to distinguish objects in low light. This rare condition is present from birth and can seriously ...
