For as long as the rule of law enriches the mighty, the mighty enforce the law. When their enrichment and dominance become threatened, they resort to might and abandon law.

The train knife attack was clearly a terrible event, but billions spent on increasing train security would reduce deaths by around zero and injuries by not very many more. There are better ways to spend the money than knee-jerk reactions to extraordinarily rare events.

They have an inverted teaching model. The students are given a syllabus and self-learn, teachers largely just run "what did you get stuck with?" sessions. Which rapidly selects for self-motivsting and engaged students who are a joy to work with. They also emphasise team projects to get work ready

IP121-30 Truth and Misinformation - Module Catalogue

Maybe someone has added the misspelling to the university spellchecker as the wrong spelling occurs in the course summary of a module about, ironically, misinformation.

Ignoring the spelling, what's it even supposed to mean? Surely there are easier ways to advertise that you're trying to fill a vacant copywriter position?

Nice to see some research progress on Bile Acid Malabsorption (you might not know what that is, but there's a 1% chance you've got it)

Good to get an update, but why is Madingley Road taking so long to happen? If it's not being done until 2028 can we use some of last year's ยฃ14M underspend to fill some of the potholes in it before then? And how can it be in category Green if it is 6 years late? Loving the greenways though!

And bear in mind that (this is staggering, but numbers from cdc.gov) US adults (18-64) ED attendance rate is around 21% per year, and admission to hospital is 5% per year. So the 5M users will have 1M ED visits, and 250k admissions. Of the Ozempic user admissions, about 1 in 60 is due to Ozempic.

So 4375 hospitalizations over 2 years for about 3 million users? That sounds pretty safe compared to the number of hospitalisations otherwise occurring from T2D and obesity-related cardio-vascular and other problems? Or is that your point? [couldn't access the full-text]

Any measure will get gamed. If the measure was aggregate net change in quality adjusted years of live then the 50% op could still be attractive. And if it's not, why do it?

Recently talking to someone involved with improving NHS "efficiency" in UK. Asked how it is measured. They gave the example of operations per surgeon. My suggestion of *successful* operations per surgeon was apparently novel. I wish people would distinguish between process and result.

For an open platform with a wide audience I can't help feeling that expanding IIT and NCC might increase engagement. Because without that I've got no idea what you're talking about.

The UK survived this, more or less, in 1987. Someone needs to do an updated Trump/Musk version, and let's hope we all survive this iteration. www.facebook.com/watch/?v=641...

Surely with the scorched earth policy Trump is wielding at a lot of important US science, the UK (in particular, being Anglophone) & Europe should be on the biggest scientific talent recruitment drive in centuries? Are we? If not, why not? The 30s analogy people are missing is the flight of talent

Heretic is an engaging if somewhat gruesome film. Hugh Grant is *so* much better as a bad guy than he ever was in his youthful roles.

Cooked.wiki definitely cuts out the noise. Great resource
