Hopefully the actuality won't be too disappointing. The embargo is related to the date of publication of the scientific paper that has sparked the whole thing.

What I can't get over is a) Why every BBC programme seems to feel the need to interview him individually - he has a schedule which includes a phone call at 9.30pm tonight, not to mention getting to a Studio in time for the Today programme tomorrow morning and b) why it takes them 3 hours to film an interview which, presumably, will get cut to a 10 second soundbite.
