In Unthreaded, Paul Matthews notes a couple of dates for your diaries:
Tamsin is on Radio 4 tonight at 8pm, along with Lawson and others, in a programme about science and politics.
There is a "Google Hangout" (whatever that means) tomorrow at 9 EDT which I think is 2pm our time, on the science/advocacy debate, with Judith C, Richard B and Gavin S.
