1 December 2023 - Cells use a transcriptional-translational regulatory loop to maintain circadian rhythms. But John O’Neill and collaborators have shown that a cell can lose its nucleus and still keep time. O’Neill and his postdoc Andrew Beale talked to us about how investigating a mysterious band on a western blot led to a new understanding of the red blood cell’s clockwork mechanism. Their preprint was reviewed through Review Commons and published this year in The EMBO Journal. We also speak with Karin Dumstrei, who handled the manuscript at Review Commons, about the editor’s role in managing the peer review process. It is the story of a weird band on a western blot, pandemic disruptions, and the importance of tone in peer review.
