And exciting presentation of fascinating data. Hat tip to a Troppodillian whose email I have now lost but who emailed me a week or so ago suggesting I watch this and write it up on Troppo. Apologies, this isn’t much of a write up, but I’m afraid I’m flat out. And I didn’t think of anything much to say except ‘watch this video’ – it’s great.
Postscript: It was Roger – Sorry about that. Thought it was, but couldn’t confirm it from my emails for some reason, so thought I’d better not nominate the wrong person.
