We are on our summer break and the editorial office is closed until 18 January. In the meantime, please enjoy our Summer Hiatus series, in which our journalists have selected articles from our 2020 news and clinical archives, The Conversation and other publications with which we share content. Please note the comment function has been turned off while we are away. Happy reading.
