Dunno about you but I'm looking forward to watching the UW Huskies play the Atlanta Hawks in a couple of weeks.

While I'm throwing out Americana recommendations, check out the latest from Mary Gauthier. The opening track Alcohol and Adderall is as good place to start as any. www.youtube.com/watch?v=tOrf...

After a long wait, brilliant Americana performer Ian Noe is back with a double album, The Canyon Falls Trailer Band. Listen to the whole thing—but here's one of several uptempo numbers that are a fun switch-up after the first two records.

"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."

Seriously, guys, just leave Gary home.
Recently, Gary’s buddies requested he not mention Palantir on their nights out together so as to not tank the whole group’s chances of getting laid. “I get nervous now. I don’t bring it up,” he says. (Gary, along with the other daters in this piece, have been given pseudonyms to protect against professional, if not romantic, repercussions.)

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

Ignore for a moment the question about whether Anthropic trains on user sessions. I am I right in reading this as saying that Anthropic's "never-before-discovered" reverse transcriptase was *patented* three years ago?
Dr. Mestre first encountered the enzymes in jumbo phages in 2022 while searching for new reverse transcriptases. He worked briefly as a consultant for ReNegade Therapeutics, which filed a patent in 2023 on a number of reverse transcriptases, including the ones Dr. Mestre found. He is listed as a co-inventor on the patent filing.

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.

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!

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.

It is unsurprising that my federal funding agencies are uninterested in covering foreign travel. What is more disappointing is that my own university has been imposing more and more burdensome limits—some in direct contradiction to their own policies—on international travel and collaboration.

I was pretty chuffed about science when the doctors at NYU figured out why my face had gone numb and I had lost the ability to speak and swallow. They turned to the scientific literature, which guided them through keeping me from dying from a rare disorder and regaining the ability to speak and eat.

When we talk about how science is broken, maybe at least consider how a huge collaboration measured the ripples in spacetime resulting the collision of two black holes 1.3 billion light years away, as counterweight the guy who had to fake his data to show that people who procrastinate fall behind.
