Sometimes, different organisms can evolve the same ability independently, a process called parallel evolution. A new study ...

Do dragonflies see like humans? Researchers discovered dragonflies use a red-sensing opsin identical to mammals. This study ...

Dragonflies have evolved special light-sensing proteins that let them see deeper red light than most animals. Researchers ...

Scientists discovered years ago that the hypothalamus -- which helps to manage body temperature, hunger, sex drive, sleep and more -- includes neurons that express the protein opsin 3 (OPN3). Far less ...

Sometimes different organisms can evolve the same ability independently, a process called parallel evolution. A new study from Osaka Metropolitan ...

Researchers at Brown University and Cincinnati Children’s found that suppressing opsin 3 in the brain of mice makes them eat less, raising new questions about the mechanisms involved in regulating ...
