Trump: There's so—rare earth. No such thing as rare earth. But there's so much rare earth. And this, to get to this rare earth, you got to go through... hundreds of feet of ice. That's not the reason we need it.

I'm really not one to support politicians more than neutral but Emmanuel Macron seems really to have done some good work with this speech. "We do prefer science to plotism [conspiracies]" 👏 (apparently the glasses are because eye surgery) www.facebook.com/reel/1325641...

I just woke up from a nap and somehow while I was asleep, everyone on the bus has figured out we are not going to the right place

Thanks to @spavel.bsky.social , at productpicnic.beehiiv.com/p/the-incred... , I saw an intriguing claim:

I am super interested in metacognition so I was hoping it was a metacognition paper and it is! So I read it

See what is happening, not what is supposed to happen
The stories we are telling around user research and LLMs have locked us into a doomed framing. Reject the very notion that it is "better than nothing."

This is one for all the #WomeninSTEM. If you are happy to, could you share some of the more awkward and unusual questions you have been asked? The ones your male colleagues would never be asked.

Lol I went back on Twitter, because there are still essentially no customer service accounts on here, found some of the early Elon-era bugs still not to be fixed, and within an hour or two received a phishing scam related to my customer service enquiry🙃

It's got to be unhelpful to spread misinformation about chemicals amongst a terrified population. The more clarity the people can have, the better

Hey #ChemSky!
I have a lab student rn who has a cast. They can use their fingers ok on that side...but, our normal nitrile gloves do not fit over the cast.
Any suggestions?

"We've lost our hair" - balding as a mark of competence. Image would have been a funny meme without the caption suggesting it's their entire workforce. That's a company not to hire I guess...

Not the worst from a pop sci video but the H2O made me lol. The arrow means small -> macromolecule evolution over millions of years so no issue with that bit.
