Just because someone is rich and highly successful in business doesn't mean their brain can't be utterly melted online.

Trump Allies Near โ€˜Total Victoryโ€™ in Wiping Out U.S. Climate Regulation

A reminder that, while some of the damage that Trump & GOP are doing might seems temporary, the damage they're doing to the planet is permanent:

Why evidence matters in health research Professor George Davey Smith explains why he encourages scientists to look for ways they might be wrong.

Mistaking correlation for causation doesnโ€™t just waste research funding, it can shape real-world health advice.

In our new blog, Prof. George Davey Smith, 2025 MRC Millennium Medal winner, explains why he encourages scientists to look for ways they might be wrong.

Isn't this a telling aspiration? To want robots to look after your kids, so you can do stuff, rather than robots to do stuff, so you can spend time with your kids?

The darkness inside these shrivelled men must be like a gaping unfillable void.

Unclear who is responsible for this. Chiltern? Arriva (the parent company)? Porterbrook (apparently owns the rolling stock?)

A murky world of shareholders, CEOs etc.

This used to be a great rail service.

Thanks for actual data! Naturally some operators must have older than average rolling stock. Chiltern looks anomalous though.

If a Pakistani Muslim owned X, distributed indecent images of girls on a platform where govt do their PR, where some receive payments for posts, they would have distanced themselves by now. X would be shutdown and Braverman and Farage would be calling for a ban and investigation into Pakistani men.

Agreed, it works well for people like us who already have driving licence and/or passport. But effectively excludes anyone without either, as it's too hard to prove identity. Not good in that regard.

I call on my party and my government to remove themselves entirely from X and communicate with the public where they actually participate online and can be protected from such illegality.

Farage: "I believe in vaccinations when they're vaccinations. I don't think what happened with Covid were vaccinations. You have to keep having them every 6 months."

Conspiratorial nonsense.

Some vaccinations like Covid shots require multiple/seasonal doses because immunity fades & viruses change.

Heโ€™s utterly unhinged and out of control. Congress could stop this in an instant, but its ruling party, the GOP, has become equally untethered from principle or reality. Too many Americans still cheering this on without any comprehension of the disastrous consequences, for themselves or the world.

I'd love to think that there is a future where authors can completely disengage from Amazon and still earn a living. Where they feel no pressure to view Amazon sales rank or total Amazon reviews as a barometer of their success. We are not there yet. But some of us can hope. bsky.app/profile/dj-a...

Itโ€™s exactly this kind of dismal, prejudiced bollox from the Daily Mail thatโ€™s got us into the ruinous Brexit mess weโ€™re in. What a moronic response to us rejoining Erasmus and all the benefits that brings. If theyโ€™re really worried about cost, they should push to cancel Brexit altogether.
