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.

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.

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

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.

A representation of how symptoms of some exemplar constructs in the DSM-5 map onto the hierarchical structure we found. On the left are examples of disorders with symptoms that mostly hung together in the data-driven structure (i.e., ‘notably homogenous disorders’) and on the right are examples of disorders with symptoms that scattered throughout the data-driven structure (i.e., ‘notably heterogeneous disorders’).

Core responsibilities include, but are not limited to data collection, data management, participant recruitment and retention, and lab administration. Opportunities to contribute to computational modeling and other analyses of behavioral, clinical, and neuroimaging data are also available. Prior experience in these latter areas, while advantageous, is not required.

 

The following skills are preferred: experience with psychopathology and behavioral assessment; programming (R, Python, Matlab, Bash or similar); [f]MRI processing and analysis (FSL, AFNI, SPM). The ideal candidate will have strong interpersonal and quantitative skills, programming experience, some experience in psychology or neuroscience research, and an interest in clinical applications of computational/cognitive neuroscience. However, applicants are not expected to have expertise in all areas and applicants with strong interests, but limited exposure, in these areas are also encouraged to apply.
