Here's a timeline list of some of the most authoritative accounts of the effects of the Chernobyl accident. If you'd rather something cripser, try the World Nuclear Association's sharp and well-referenced account.  Read more...

The case against six protestors collapsed today in the wake of an extraordinary saga involving an erstwhile undercover policeman. Even now, early in the story's unfolding, it is worth saying that in principle the police are probably right to operate undercover amongst protestors, even at considerable expense. Read more...

Some people promote and millions believe the idea of a very high number for Chernobyl's cancer death toll. (See the 100,000 figure promoted by some Greens, and that's almost moderate.)

Stephen Fry has visited the coastline and the waters of the US's Gulf of Mexico and declared them to be, well, what? The victims of a spill, obviously. Maybe even the victim of the clean-up, for all we know. But not, he feels, the victim of any obvious post-accident wickedness or folly on BP's part. That was, I think, the take-away message of Stephen Fry and the Great American Oil Spill (BBC2, 7 November 2010). But the interest of the programme is not limited to Fry's being fairly sensible.

This week's Culture Show on BBC2 was as entertaining as ever, but Tom Dyckhoff shouldn't have been allowed his Tory-bashing moments in the piece on planning. (And a word on the Tea Party.)  Read more...

This is a wonderful vignette. Read more...

It is a famous mystery whether David Cameron believes in a smaller state and indeed whether this of any other beliefs matter to him or his politics. This weekend, we seem to be a little nearer a plausible answer. Read more...

Better late than never, I read this memoir which is destined to be a classic, surely. Read more...
