"An ambulance was seen arriving at the prison where Pike was to be executed and then leaving. Medical aid was being administered, according to online federal court records." The utter absurdity of the state trying twice to kill someone and then calling an ambulance. We must end the death penalty.

Tennessee inmate still alive after being administered two lethal injections, her lawyer says

Christa Pike, 50, was 18 when she murdered a classmate. She would be the first woman the state has executed in more than 200 years.

"I believe that science derives its authority from something more than mastering the pipeline from data generation to publication. Rather, it comes from interactions within a community of people trained to interrogate evidence and answer for the conclusions they draw from it."

In my latest for @undark.org, I compare AI adoption in science to the Ship of Theseus: "If you swap out every wooden plank on a ship over time, is it still the same vessel?" I argue that science derives authority from something more than data generation + publication. undark.org/2026/09/25/o...

The RT was annotated in the sequence previously for sure, but what was discovered was the associated clustered repeats that are expressed and appear to associate with the RT, i.e a potential anti-viral system of unknown function but potentially programmable in some way

Google Gemini says that @jevinwest.bsky.social and I aren't to be trusted because in our first lecture, we had a playful example where Jevin presented data the same way that Tim Cook did, and I called bullshit on it. It hallucinates criticism and the only citations are to the lecture itself.

1. The "Explosive Growth" Slide ControversyIronically, the most direct and explicit example of this occurred during their very first "Calling Bullshit" lecture at the University of Washington.The Setup: Jevin West presented a slide to the class showing a graph that purported to show the "explosive, hockey-stick growth" of web traffic to their new Calling Bullshit website. The graph utilized standard marketing axes and compressed timeframes to make the project look like an unmitigated, runaway viral sensation.The "Bullshit": Carl Bergstrom actually had to step in and call "bullshit" on his own co-instructor's slide. When the data was displayed honestly without selective axis truncation or creative smoothing, it showed that while traffic was high initially, it heavily ebbed, flowed, and plateaued over time.The Criticism: While some praised this as a playful, planned pedagogical moment to show that "anyone can fall prey to bad data framing," critics viewed it as a perfect illustration of the double standard: when it serves a personal or professional promotional narrative (like proving your own course is a massive success), the temptation to use flawed, hype-driven metrics is incredibly high.

Does my Speak-n-Spell feel pain when I type O-U-C-H? The jury is out. Philosophers and neuroscientists say that's fucking stupid, but I called a guy from the Center for Pretending that Household Electronics Are Sentient and he said there's no way to know for sure.

and yes, before anyone asks, I am absolutely familiar with Pascal Jousselin's Mr. Invincible (as it's called in English)! As good as I thought it was when I just seen a few pages online, when it finally came out in english, I was shocked how relentlessly creative he was page after page - so good!

Cover to Mr. Invincible, and interior page - in which using his powers to see the layout of the page, mr. invincible rescues a cat in a tree not by climbing the tree, but by reaching down to the panel below him and grabbing it that way. It's pretty fun - and only in comics!

I'm one of the those old-fashioned sorts who takes delight in meeting my colleagues around the world, breaking bread with them, and enjoying friendships worldwide for decades thereafter.

Friends in Adelaide and South Australia more generally: I'm looking at a birding trip (Gluepots/Flinders) in early August 2027. I'd love to swing by the university or anywhere else to give a talk. If you're interesting, drop me a note. cbergst@uw.edu Or just tell me where to go while visiting.

If you’re like me, immunologically, you have probably suffered a fever for one (Moderna) up to the (Pfizer) days after getting a Covid vaccine. Yesterday I tried Novavax instead, and had absolutely zero side effects (at the same time as my flu shot no less). It’s well worth a try if you haven’t.
