A wild thread:

490 million years ago, the seafloor which would become the city of Baltimore was a serpentinite-hosted hydrothermal vent complex.

Those vents laid the ultramafic structures that would, in 1812, be discovered as America's first chromite mine.

That Red Roof! Those Tiffany Lamps! It’s a Pizza Hut From the Past. With heaps of nostalgia but little promotion by their parent chain, Pizza Hut Classics take their fervent fans on a time trip back to a simpler, warmer era.

There are at least 60 Pizza Hut Classics (red roofs, checkered tablecloths, salad bar) in the US…but the company does nothing to promote them. “They are like wormholes in the chain restaurant galaxy, portals to the past found by serendipity.” [nytimes.com]

As everyone knows, the Country of Canada has treated the United States very unfairly for decades. Now, things are turning around for the U.S.A., and FAST! But imagine, Canada is building a massive bridge between Ontario and Michigan. They own both the Canada and the United States side and, of course, built it with virtually no U.S. content. President Barack Hussein Obama stupidly gave them a waiver so they could get around the BUY AMERICAN Act, and not use any American products, including our Steel. Now, the Canadian Government expects me, as President of the United States, to PERMIT them to just “take advantage of America!” What does the United States of America get — Absolutely NOTHING! Ontario won't even put U.S. spirits, beverages, and other alcoholic products, on their shelves, they are absolutely prohibited from doing so and now, on top of everything else, Prime Minister Carney wants to make a deal with China — which will eat Canada alive. We’ll just get the leftovers! I don't think so. The first thing China will do is terminate ALL Ice Hockey being played in Canada, and permanently eliminate The Stanley Cup. The Tariffs Canada charges us for our Dairy products have, for many years, been unacceptable, putting our Farmers at great financial risk. I will not allow this bridge to open until the United States is fully compensated for everything we have given them, and also, importantly, Canada treats the United States with the Fairness and Respect that we deserve. We will start negotiations, IMMEDIATELY. With all that we have given them, we should own, perhaps, at least one half of this asset. The revenues generated because of the U.S. Market will be astronomical. Thank you for your attention to this matter!

Trump, in the middle of his latest unhinged Truth Social screed, claims that if Canada makes a trade deal with China, "the first thing China will do is terminate ALL Ice Hockey being played in Canada, and permanently eliminate The Stanley Cup."

BREAKING: The Maryland House passed a congressional map that would eliminate the state’s last GOP-held seat. Democrats say the move is necessary to counter Trump-backed gerrymanders.

All of this is fucking senseless. Minnesota did not have an immigration problem. Trump sent his Nazi thugs here because he's racist against Somali people and to own libs like Tim Walz. Now two Minnesotans are dead and Minneapolis is on the verge of going up in flames. None. Of. This. Was. Necessary.

Bill Cassidy reportedly voted for RFK Jr because Cassidy was afraid of losing his next primary and feared Trump endorsed his further-right opponent.

Trump just endorsed Cassidy’s opponent anyway!

This needs boosting.
How we share data now, determines how prepared we are for tomorrow. That includes having access to *all* who need it (inccitizen scientists like @ryanhisner.bsky.social) & being able to use it in dashboards & apps.
Having one place control it all - is dangerous.

1/ Aaron Siri is presenting to ACIP right now. He's not a vaccine scientist. He's a plaintiff's attorney whose firm profits from vaccine-injury litigation, RFK Jr.'s personal lawyer, and someone who helped vet HHS leadership. He's now advising the committee that sets U.S. vaccine policy.
