Tucked away off a side street near Old Street, it sits in the basement of a new-build block. They even share the same entrance, so you get the odd thrill of wondering whether you're heading for a spa treatment or someone's Amazon delivery. Once you're downstairs, the walls are plastered with celebrity photos, quotes and snapshots. Kate Moss apparently floated out feeling fantastic after a visit with her aristocratic beau, while Renée Zellweger, like us, seemed stunned that this even exists on Micawber Street.
Following publication of this article, we were alerted via PubPeer to an inadvertent image duplication in Extended Fig. 7b in our paper. Upon carefully examining all the figures, we have discovered another duplication error in Extended Fig. 3g. The errors occurred during figure preparation by using placeholder images originating from similar areas of a well. The errors do not compromise the results or the conclusions of our work.
