Longitudinal tracking reveals developmental transitions in zebrafish clock gene expression https://www.biorxiv.org/content/10.64898/2026.05.18.726011v1

“These findings demonstrate that the zebrafish circadian system is not assembled through a single synchronized onset of clock gene expression, but through gene-specific regulatory programs that shift across development.” New #zebrafish work from @jkimmey.bsky.social 🐟 ⏰
