Today, for @rewirenewsgroup.com, @madisyn-writes.bsky.social looked into the to the limited data and conflicting guidance around breast cancer screening options for trans women. It's troubling. And it could have life-changing consequences for patients. I hope you'll give it a read.

SCOOP: 'Tommy' from the now-viral exchange with Abdul El-Sayed is Thomas Teepell, a former staffer for Republican Senator Josh Hawley with close ties to Christian Nationalist Sean Feucht. He's the son of a former Bobby Jindal staffer whose consultant work was instrumental in getting Hawley elected.

A lot of people pointing out the sinister potential of this tool to personalise insurance premiums based in your appearance. If you look older and more frail, then you'll have to pay more!

Can a ‘new AI tool’ predict cancer survival from a single face photo, as reported in @theguardian.com? Yes. Modestly. In people having radiotherapy, many with advanced cancer, their faces unsurprisingly show signs of how sick they are. But is this actually useful?!

A new concern about this story: if AI writes the proof and AI formalises it in the proof-checking software Lean, mistakes can happen in that second, translation step.

Good end-of-FY coverage by the Times. The amount of unspent funds has wiggled but it was pretty clear for some time now that NSF was simply not going to spend a substantial portion of its congressional appropriation this year.

Four days ago, a scientist was surprised by the news that Anthropic discovered new virus genes for making DNA. He says he’s been studying them for years—and feeding his data to Anthropic’s AI as part of his own research. Coincidence? Here’s my story. nyti.ms/3VSWayc

Seems like a good time to re-up this post. It is a list of 26 Dems at the statewide/national level that have made anti-trans statements or voted anti-trans policies. I do not advocate for abstaining from all of the ones on this list, but if the worst offenders who call us “biological men,” I do.

In Massachusetts, we have a responsibility to protect the vulnerable and stand up for those who need it. We don’t throw trans kids under the bus for political points. We protect them—and all of our neighbors—because trans rights are human rights.

Finally, this has gone a bit under the radar, so I want to highlight it: The social, behavioral and economic sciences directorate (SBE) has simply ceased to deliver grants to many of its subareas. Any topic not specifically OK'd by the Trump administration is receiving zero new awards.

Scoop: For nearly a year, NSF has struggled to make new grants. Now we know that it will not catch up. In fact, NSF will award just 6,100 new grants—a 30% y/o/y decline, itself down from a previous avg. of 11,000+. In fact, the last time NSF awarded so few grants was in the early '80s.

there is no such thing as "age verification." All "age verification" is actually "identity verification." You can coat it in glitter and "privacy-preserving" wrapping paper. But in the end, mandating age verification means mandating surveillance be built into software and hardware. Period.

Neat update to the quantum solution of this problem: turns out you really do need entanglement. (You'll note that there are 5x5 and 7x7 colored squares in the image—that's because the classical 6x6 does not exist.)

In the 1700s a Russian empress asked a polymath to solve a puzzle. In 1901 a mathematician proved it unsolvable. A century later, researchers found that this wasn't the case if the puzzle went quantum. Now, researchers know just how much quantumness it takes www.newscientist.com/article/2584...

If there’s a tool that lets me “write” 10 articles a year instead of 1 without any change in my life, let me say: I have zero interest in that Since it’d obviously ramp up “productivity” talk, further perverting an area of life where volume is not an end in itself, I’d avoid it on that ground alone

Anthropic has announced that it will include a watermark on text generated by its future models, and create a public detector tool. A win for transparency, but will it improve academic integrity or reduce slop? Probably not much...🧪 More in my story here: www.nature.com/articles/d41...
