Abstract:Xu et al. recently demonstrated that cryptochrome 4 (CRY4) protein, as a light‐dependent magnetic receptor, can sense geomagnetic fields to guide night‐migratory songbirds' navigation and evolution by the formation of composite radical pairs and electron transport. We aim to comment on CRY4 through radical pairs and electron transport for magnetic sensitive in night‐migratory songbirds' migration and evolution. Additionally, we find that the role of magnetic fields is deeply concerning to the scientific commun… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
