Another chemical triumph for artificial 'intelligence'?

Single-Channel Saturation at the Quantum Conductance Limit in Single-Molecule Junctions Electron transport through a single quantum channel is fundamentally limited by the conductance quantum (G0 = 2e2/h β‰ˆ 77.5 ΞΌS), achievable only in fully transparent systems without interfacial scatter...

There have been many attempts to design molecules that would give metal-single molecule-metal junctions as near unit quantum conductance as possible, but here's an outrageously unlikely-looking one which succeeds! Remarkable work: doi.org/10.1021/jacs...

And assuming Ms. Tyers isn't a bot, I'd risk a shrewd bet she was last in church for her own christening.

I've heard them, up in Leighton Moss, but I've never managed to spot one. Great photo!

I came off my bike on a massive pothole I failed to spot under trees, broke collarbone and 3 ribs. Friend went to the location next day to photo it for a claim; East Cheshire Council had miraculously mended it.

Charisma is an overrated characteristic. Johnson had it in spades, apparently; need I say more?

What I really admire about 2FA apps is their chutzpah, asking if you’re enjoying using them. Bit like a water company asking if you’re enjoying using the sewage system.

Best wishes for a speedy recovery and no after effects! An uncle had prostate cancer so it’s something I also keep an eye on.

Last night there was a vigil for the first cycling fatality of the year on London's streets. I was there. Here are some thoughts (no paywall).

If this strikes a chord with you, please comment on the post and share.

Since Farage is himself notoriously racist, he presumably approves.

Went to a concert last night in St Mary’s Woolton, by the Metropolitan Cathedral Choir reinforced by some children, mostly girls, from the local primary school. The enthusiasm of the children in particular was heartwarming.

Yes, it would be nice to have the choice. Hence, designing infrastructure/built environment so it's not utterly car-centric *would* provide people with a choice, which I for one, as a cycle commuter, would welcome.

I did't know there was another bye-election due in North Minehead. Mr Hilter is showing his age. And... oi still don't look the sound of them there boncentration bamps, either.

Am reading up on weight loss drugs because someone I know asked me if I thought it was reasonable to get a new one, that is still in stage 3 clinical trials but is available cheap, from someone she knows, who (somehow?) obtained it in Europe and is using it himself. Jesus!

The hidden dangers of weight-loss drugs - video Millions of people are taking weight-loss drugs like Ozempic and Mounjaro. but with so many unanswered questions, are we in the middle of a giant human experiment?

What a triumph of free market capitalism: artificial hormone- based weight loss drugs, to offset the toxic effects of ultra processed, addictive 'foods'. Surely there is a better answer? Like, eating real food? www.theguardian.com/world/video/...

Sad to read of the death a couple of days ago of Fernando Mamede, the hugely talented Portuguese distance runner, breaker of Henry Rono's 10,000 m world record... but flaky when it came to major championships.

In policy terms it's hard to put a razor blade between Badenoch's ideas and Reform. I'm guessing the only reason there have been so many defectors is that they hope people will forget they were in the last Government as Tories.

We are also having haggis, neeps and tatties. Just hope it doesn’t exacerbate my occasional gout.

Trump's Davos speech reminded me of something- I've been trying since to figure out what. Now I've succeeded; his speech patterns are similar to those of the drug-addled, dreadful American gangster media employee, Kudzuvine, in Tom Sharpe's 'Grantchester Grind'.

A pleasant interaction with a driver today; waved thanks to an Audi (!) driver who waited for 20 s or so while I negotiated a dangerous LH bend in primary position, then overtook me leaving a lane. It still does happen, sometimes.

Was very interested to come across your book here. My late father in law Harry Kelly was a Jolly in 44 Commando in Burma. He was also, earlier, Captain of the Royal Marines football team. He talked more about tossing the coin at Hampden Park once than he ever did about Burma.

Interesting response, and it's a point of view for sure, but I note that you didn't answer my question.

We had a German teacher, who was shuffled off to our high school after a discipline incident at the associated junior school, where he brought in a katana, unsheathed it and put it on his desk, saying he hoped everyone would now behave. This was the 1970's; stuff like that happened all the time.

He's succeeded in almost unifying political parties in the UK in their response to this (notably apart from Deform's Farage, who has, predictably, said nothing). I don't think it's ignorance; he's just playing to his base, who will hear his accusations but never hear the refutations.
