After this week's hangover cure leaves us in suspense, British Academy Global Professor Siddharth Kara shares his horrifying research on the exploitation and inhumanity at the heart of the cobalt mining industry in the Congo upon which current rechargeable battery technology relies. Sebastian then brightens the mood with the first of several segments on a subject which the Western public remains ignorant: the history of the Soviet Union. Spoiler: it's not all gulags and show trials, but there were still plenty of those.
