Scouting America wastes no time in pushing back on SecDef Hegseth's claims that it agreed to limit membership based on assigned sex: "We have transgender people in our program, and we’ll have transgender people in our program going forward,” said CEO Roger Krone.

Vaccine Panel Stacked by RFK Jr. Recommends Delaying MMRV Immunization The vaccine advisory group ACIP, not all members of which seemed to know what the group does, recommended to the CDC that combined MMRV shots not be given before age 4.

On Feb. 28, 1998, Andrew Wakefield published a paper in The Lancet claiming that the MMR vaccine causes autism.

It doesn't.

And that awe and wonder also feeds into economics. I’ve helped numerous bestselling UK authors with science questions, inspiring books, boosting publishing & royalties.

IDF accepts Gaza Health Ministry death toll of over 71,000 Palestinians killed in the war Although Many International Experts Have Accepted the Health Ministry's Data as Reliable, and Even Conservative Relative to the True Death Toll, Israel Had Refused to Accept the Health Ministry's Coun...

I cannot tell you how much doubt was consistently directed at the Gaza Health Ministry’s casualty numbers and how much pressure was put on news organizations to couch those numbers as unreliable.

Biden himself said they were fabricated!

Gosh I wonder who’s going to profit from this war? Because it sure as hell isn’t going to be β€˜working people’ Keir Starmer, or all of the pub-goers who Farage seems to be fixated on.

Could it be… private corporations and their wealthy shareholders by any chance?

The subject also applies to many other countries eg. Aus, Can. You made an assumption which was wrong. You beed to own that mistake, not quibble.

While we sit around to find out how bad exactly it all is, a bit of cheer: the best baguette of Paris competition was won by a Sri Lankan who appears to have started as a dish washer in restaurants and eventually trained as a Boulanger.

People are going to keep insisting that UK anti-trans politics is really composed of jilted lefty feminists even as its leaders are literally running as Tory candidates.

Why aren't you having another revolution then? Forgotten the issue of no taxation without representation?

Ignoring the fact that our host was talking about the UK not US, isn’t it the case that permanent legal US residents pay tax, and that you had a whole revolution about no taxation without representation?

Historically, these are TERRIBLE polling numbers for day 1 of a major US use of force, particularly against a well known and disliked adversary. Usually it only goes down from the start

Years ago in another life I gave a guest lecture at The Hague warning β€œAI weapons” could be invoked to remove accountability for war crimes from the chain of command. I said β€œthere are no autonomous weapons, only unsupervised ones,” and sadly it seems I was cooking with that one

The impact of job insecurity doesn’t fall equally. PhDs & graduates from poorer and diverse, backgrounds can’t afford employment gaps so are more likely to leave forever. Black, women, minority, working class, will go leaving a less diverse more establishment community behind & Labour are doing this

On top of all the reporting that this war of aggression was planned well in advance, it seems that the reporting also indicates that the US political leadership are quite literally too stupid to understand basic diplomacy. I mean literally not smart enough.
