In south-west France, in the foothills of the Pyrenees - a gorgeous moth, with 'baby alien' image on its wings. What's the universe trying to tell us? Please retweet and/or identify.

Congratulations to Prof Alice Roberts💙. Hooray from John Man, Mongoiist and friend of Mark Horton.

Watch out, people. Something wicked this way comes: Gleichschaltung (" coordination"). This, to shorten Wikipedia, " was the process by which Hitler established control over all aspects of German society".

Just back from Inner Mongolia, researching Hulunbuir. What?? Vast grasslands, infinite forests, bigger than the UK and full of history. Never heard of it? You will.

The Hu: Check out this Mongolian rock band, in Camden. Powerful, original, a brilliant mix of old and new. Genghis would have been proud.

Covid Report is vital. It's becoming clear that expertise - the people, the modelling - was chosen to fit the policy.

At each stage, Cummings had choices, all 'reasonable' but not all moral. Leaders make hard choices to serve others. He made easy ones to serve him and his family.

It's obvious what has to be done. Commission a review, put it with the other reviews, then review the reviews, so that we have enough evidence to commission a final review. Then we'll know enough to act without telling anyone why.

Re: Mark Sedwill’s depoarture: It’s what dictators do – put your guys at the top of every institution. That’s how you impose your will. The Nazis called it Gleichschaltung, ‘equal-switching’/ coordination, synchronisation. Don’t worry: it could never get that bad here. Could it?

In Zimbabwe they arrest you if you protest against corruption. This is because corruption is part of the nation’s identitity. To protest against it is treason.

Re Belarus: Note to Mr L: 80 per cent? That's pathetic. If you can't get 99 per cent, it's all over. You better get out while you can.

Pulled over for speeding. Sure I broke the law, but only in a limited and specific way. So that's all right.

The Birmingham Eternal Wall: it's a Möbius Strip. Apparently, it's for Jesus. Beautiful, but daft.

The 1933 Enabling Act gave Hitler the power to rule by decree. It was originally called the Law to Eliminate Need. Sounds a great idea. What could possibly go wrong?

The Social Dilemma. Watch. Fear. Act.

Brexit: nations and cultures die, but is there any other case of suicide?

When did we start referring to all relatives as 'loved ones'? How can we know if they're loved or not? Let's get back to calling them 'relatives.'

I just signed the petition calling on Culture Secretary Rt Hon Nadine Dorries to scrap her damaging plans to sell off Channel 4! Can you add your name too? #SaveChannel4 speakout.38degrees.org.uk/campaigns/keep…

Manston: This is not an 'invasion'. It is a gift. We have good reasons to look after them: humanity and self-interest. Weed out the bad and benefit from the rest, as quickly as possible, for their sake and ours.

This week is the 70th anniversary of the Great London Smog. 12,000 Londoners died. Some things do improve. Now for clean air world-wide.
