A review of 18 studies found no consistently reproducible subtypes of schizophrenia, suggesting that differences in brain structure across patients may reflect a spectrum rather than discrete biological categories.

The Real Reason ICE Agents Wear Masks
Face-coverings may work less to protect federal agents from danger than to make it easier for them to do unconstitutional things.

Kare 11 local news just read, in full, this statement from Michael and Susan Pretti, the parents of Alex Pretti. "Please get the truth out about our son."
Statement from Michael and Susan Pretti
Parents of Alex Jeffrey Pretti

“We are heartbroken but also very angry.

Alex was a kindhearted soul who cared deeply for his family and friends and also the American veterans whom he cared for as an ICU nurse at the Minneapolis VA hospital. Alex wanted to make a difference in this world. Unfortunately, he will not be with us to see his impact.

I do not throw around the ‘hero’ term lightly. However, his last thought and act was to protect a woman. The sickening lies told about our son by the administration are reprehensible and disgusting. Alex is clearly not holding a gun when attacked by Trump’s murdering and cowardly ICE thugs. He had his phone in his right hand and his empty left hand is raised above his head while trying to protect the woman ICE just pushed down, all while being pepper sprayed. 

Please get the truth out about our son. He was a good man. Thank you.

One case for the likely complexity is that BPD is a very heterogenous dx... individual BPD symptoms imply important interpersonal processes, but the symptom profile of any one person with BPD may or may not include these!

In our rejoinder, we argue 1) Dark terminology isn't used responsibly as BL et al. claim, 2) the term can be replaced with a more sensible and scientific one, 3) data support our position (Stanton et al., 2025), and 4) popularity ≠ importance. @davidchester.bsky.social @drlynam.bsky.social

Ah I see, interesting. I guess the goals in descending order of urgency are: (1) prevent egregiously bad science, (2) enhance scientific impact, and (3) improve the article quality.

Primarily, whether the (a) aims/hypotheses are reasonable given the literature and (b) methods/results support the conclusion. Secondarily, I focus on the overall article quality (accuracy, clarity, figure efficacy, etc.).

Ursula K. Le Guin on the true pain of being a writer
Screenshot of a single question and answer from interview in the Times Literary Supplement with Ursula K. Le Guin. Here is the quote:

If you could make a change to anything you’ve written over the years, what would it be?

In The Dispossessed, I would mention the communal pickle barrels at street corners in the big towns, restocked by whoever in the community has made or kept more pickles than they need. I knew about the free pickles all along, but never could fit them into the book.
