Ok, long thread: I think the adoption of such an AI sifting approach builds quite logically on the pernicious foundations that are already in place at UKRI and many other funders, where the deep expertise of panel members and reviewers is regularly sacrificed on the altar of objectivity. 1/n

The brilliant Kris Kuo, with help from Fabian and the Werner lab, has identified a key driver of cyclic gene expression in Sulfolobus, which has a cell cycle but no CDK/cyclins. Amazingly, TFB2 has a cyclin box that regulates its degradation as cells exit division. Another reason to love archaea!
