Our new paper is out now!
We show the non-image forming role of #Rhodopsin7 in #Drosophila, expanding our understanding of #opsins beyond classical vision.
This work highlights how #Rh7 contributes to extra-retinal light sensing and plays a role in behavioral light responses.

Policarpo et al. analyse 535 genomes to study opsin evolution across ray-finned fishes. Visual opsins are more prone to duplications and losses than nonvisual opsins; fish that rely on electroreception show a reduction in both opsin types.

Our recent article on non-visual opsins in lizards - which made the May cover - is the focus of a new Highlight.

The tuatara and many lizards possess a parietal eye, where non-visual opsins are expressed. Romero & @fsjsouza.bsky.social compared 60+ genomes to study the evolution of non-visual opsins, suggesting a functional role associated with the parietal eye.

Happy to share my paper at PNAS!
