Thanks for the tip. I've been working on figuring out Andrena to get through our backlog of specimens at Virginia Natural Heritage. Some of them make sense and others I'm putting off until later, but I'm enjoying the challenge.

Thanks; mostly I'm looking for more info on recognizing A. arabis here in Virginia. Ribble's paper on Rhacandrena refers to this one for more info.

"American innovation" now refers to making a kind of atrocity cronut by combining insider trading with war crimes.

there's a lot of specific overwhelming and massive crises happening at once and every single one has at its root elites who did crimes and never suffered consequences for it.

You sound like an unhinged person if you in plain words describe what’s happening, but the Trump admin demanded Anthropic’s AI be able to kill things for it w/out human approval and also do mass surveillance.

Anthropic said no, and now the admin is trying to destroy the company in retaliation.

I continue to be fascinated by the phenomenon whereby an expert engages with any of the LLMs on their field of expertise and is instantly horrified by the wrong answers, and then goes on to use it for things they are not experts in as though it won’t be just as bad for those.

I'm just finishing interpreting the DNA barcodes on my wasps, and now it turns out you can regularly have different barcodes in the same (sawfly) wasp! πŸ˜…

Nice work, and something to keep in mind when splitting wasps into species based on DNA.πŸ§ͺ

This push for AI at the NSF grant-making level is less discussed than other AI drives but is highly consequential because it creates incentives that change entire fields. People will pivot away from other research that isn’t being funded to this and many won’t come back.

Functionally, this is the end of foundational science research in many fields in the United States, the money taken away to subsidize already wealthy billionaires and their companies.

White House to pause $259M in Minnesota Medicaid dollars in fraud crackdown It’s the latest in a growing list of fraud-focused threats and probes from the Trump administration.

This is about political retribution.

Trump is weaponizing the federal government to punish states like Minnesota that didn’t vote for him β€” ripping away funds from pregnant women, seniors, and people with disabilities.

You don’t fight β€œfraud” by hurting the most vulnerable.

The boys’ club: How Epstein’s influence shaped the exclusion of women in STEM In one email, an AI researcher suggested it’s β€œhard to be brilliant if you are worrying if you look fat or why another woman hates you.”

There were so many of us, exactly when these emails were being written, expressly working to undo the harms of sexual harassment and sexual discrimination in science. And so many people refused to believe us that any of it was real. It was all real.

The Epstein files document what many women researchers have long experienced but rarely seen laid bare so starkly: exclusion operating behind closed doors, shaping who gets funded, invited, mentored, and taken seriously. How many of these networks, norms, and gatekeepers remain in place?

When you put it like this, a $75 million bribe to Melania and gutting the Washington Post seems like a small price to pay.
