UCL puts on regular and free lunch time lectures for all and sundry to attend. This month, the popular scheme goes on tour to the Guardian offices in King's Cross. In another break from tradition, you'll need to pre-book for these lectures, but they're still totally free of charge.
18 June, Sex and the Somme. Clare Makepeace of UCL History talks about the popularity of brothels among First World War soldiers, and the rise of venereal disease. The event is now fully booked, but there's a wait list.
19 June, Investigative conservation and the archaeology of the Western Front. Renata Peters of UCL Institute of Archaeology talks about recent discoveries from the trenches, and what artefacts and recovered human remains tell us about life on the Western Front.
25 June, Reconstructing Broken Bodies: From Industrial Warfare to Industrial Engineered Tissues. Prof Robert Brown of UCL Surgical Science and Colin Hopper of UCL Eastman Dental Institute & UCH look at the reconstruction of damaged faces in WWI, and how modern techniques of tissue engineering can achieve remarkable results.
26 June: Science and the First World War. Prof Jon Agar of UCL Science and Technology Studies looks at the role scientists played in the war, and how the practice of science was perceived in different ways.
Booking instructions can be found on individual event pages. So why not use your lunch hour for something more constructive than idly flicking through Facebook, and get a peek inside Guardian HQ? If you can't make it, all lectures are streamed live on the UCL website.
