Aides to Andy Burnham have been talking to EU experts in a range of organisations about how the public would view a promise to rejoin, as momentum builds behind including such a pledge in the next Labour manifesto.

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!
