Am not surprised to see Damien Woods. Few years ago I got to see Nicolas Schabanel on a talk about dna tiles as computing block, a long time partner of Woods IIRC. Fascinating subject since they went up to Game of Life and had a form of compiler for it. The only issue was stability with large "programs" which impeded more abstract stuff (say lambda calculus). Ultra exciting stuff and ultra concerning too.
btw Schabanel university math group (Paris Diderot IREM) just made a peertube instance to host videos
