RFK Jr on Tylenol and autism: "It is not proof. We're doing the studies to make the proof."

Whether it’s Joe Biden attending weekly mass or Donald Trump’s ICE agents shooting a priest in the face with a pepper ball, presidents of both sides have directly engaged with the Catholic faith.

Add another unpaid cost that using fossil fuels imposes on us.

Odds the folks who are worried about birth rates will care? Zero.

“Our early results showed that the first trimester of pregnancy is a time to be especially… One of my previously published studies found that for every additional 10 micrograms of particulates per cubic meter of air there was a corresponding 10 percent increase in infertility risk.”

Of course, I also suspect that any companies based around other technologies are happily jumping on the AI bandwagon before the wheels come off, so they'll only have themselves to blame.
jtimmer.bsky.social
There are a lot of potentially promising uses of AI that don't involve LLMs and all the problematic behavior that comes with them. But I suspect that when the LLM bubble pops, everybody will view it as an AI bubble, and all the promising stuff will be set back years.

Reuters photographer Jonathan Ernst noticed that Bondi flipped open a file during the Senate hearing and he zoomed in.

Inside were her crib notes for attacking the senators.

The GOP now practicing Cliff's Notes Fascism

In other words, under oath Bondi was purely a performance.

I suspect I'd be net emdash zero if it weren't for one particular writer (and @kionasmith07.bsky.social knows who that is).

If an emdash needs to be deleted, force an actual human editor to do the deleting.

The things they do choose to publish reflect their values.

Based on the published evidence, it's clear that those values often include provocation, subjective thoughts about the importance of the opinion holder, a highly selective need for balance, etc.

I can't bring myself to read the column and find out what the supposed nuances of Hesgeth's "our military exists to kill people" are.

I'll just highlight once again that opinion page editors have broad discretion to decide what opinions are worth publishing—they reject things all the time.
maxkennerly.bsky.social
Despite appearances, this is not a @nytpitchbot.bsky.social joke, it's an actual @nytimes.com column by some Claremont hack who praises Hegseth for his "nuanced vision of the military’s purpose and its relationship to civilian society."

Kind of odd that today's Nobel in physics is for work that was fundamental to the development of the transmon, and two of the people receiving it have headed Google's quantum computing efforts, but a lot of the coverage seems to be "it's about quantum tunneling".

Some of the provisions of the Compact work at cross purposes and/or are contrary to some of the Administration's other policies. So, even if you assume they are genuine about some of the provisions, you'd be left guessing as to which ones are serious.

I understand the impulse to highlight the acceptable things that can be found in the "compact" and imagine how those could be built on.

But those elements are a disguise. The gov't doesn't care about them. The *purpose* of the compact is unconstitutional federal control over higher education.

The US is pursuing "energy dominance" and forcing allies to buy US oil and gas. And, yet, China is beating the US on energy exports.

One thing that comes through awfully clearly in these ICE videos is how many of these goons gravitated toward the job because being able to assault people with impunity is a big thrill for them.

My sense is that the press has so deeply absorbed the idea of "just present the facts, lest you be accused of bias" that it's getting in the way of the whole purpose of journalism, which is to help your readership understand the world.

(See also @jayrosen.bsky.social's view from nowhere argument)
jtimmer.bsky.social
None of this is joining the resistance or showing off some sort of left-wing affinity. It's all good reporting that leaves your readers with a clearer picture of the news and its import.

Yet none of the coverage I checked included it.
jtimmer.bsky.social
I think that any reasonably objective analysis would conclude that either the apparent favoring of science here is insincere given the administration's other actions, or the compact is poorly thought through and works at cross purposes with other administration policies.
jtimmer.bsky.social
I'd argue that merely reporting the initial fact that this provision exists without providing this other information as context is leaving your readership under-informed.

Simply describing these facts without analysis is also likely to leave your readers confused, as they make little sense.

It's also objective to note that the same compact wants schools to disclose the employment status of graduates in different majors, suggesting the administration is annoyed about schools producing lots of unemployed/underemployed graduates.
jtimmer.bsky.social
And it's just as objective to highlight that the Administration has also proposed massive cuts to the grants that would normally pay for these majors to attend graduate programs and advance in their careers; combined, these will leave us with a surplus of unemployed low-level scientists.
