Today is Anni-Frid Lyngstad's 80th birthday, and I'm going to celebrate by posting one of her songs below. It's not something she did with ABBA, and also not "Something's Going On", which I think was the only solo US hit by a member of ABBA. Instead, enjoy her Swedish-language David Bowie cover:

Trump was _already_ "President most likely to be associated in the public consciousness with a particularly specific melange of odors" and I don't think this is likely to move the needle on that.
This alone would've gotten a previous president laughed out of office so fast there wasn't time to impeach him.

In a day and age where large research projects can involve collaborations with dozens (or hundreds!) of co-authors around the world, this would end science in the USA if actually enforced.
Of course, I suspect it's "only" a vehicle for blacklisting basically any scientist they want to target.

Yikes. Banning people for activities such as co-authorship and advising a graduate student is completely unreasonable in a modern research environment. And a retroactive 5 year ban is wildly unfair.

Cal Raleigh had an exceptional year. Good for MVP in a great many seasons. In my view, this wasn't particularly close though. Judge is doing absolute freak shit at the plate, but he's been doing it so consistently that it doesn't feel that crazy anymore. Which is nuts!

Get outside into a dark place if you can tonight - no guarantees, but a possible brilliant display of the northern lights.
We have upgraded our geomagnetic forecast today (12 November 2025) to the highest intensity level amid an ongoing solar storm.
Current predictions suggest that the activity will result in potentially the largest solar storm to hit our planet in over two decades.

This description of “science as practiced in its best form” is a great example of Everyone is 12 Theory. You can disagree that it’s impossible for you to throw a football to the Moon, but you’re not practicing science by doing so.
