Another fresh preprint from the lab! Menarche marks an inflection point for female brain and mental health trajectories. This milestone may identify a critical window for screening. This is an effect you don't need stats to see (though we did those too). Led by @carinaheller.bsky.social 🧵👇

🚨Preprint Alert 🧠 Our new preprint „Menarche onset is an inflection point for mental health and brain development“ is now online! 👉 Preprint available here: www.biorxiv.org/content/10.6...

Very excited to announce our new preprint, led by @hollysully.bsky.social, that presents, benchmarks, and validates a method to estimate brain iron content from routine fMRI scans! It comes complete with a BIDS app! Check out the preprint and thread below! doi.org/10.64898/202...

Updated preprint: doi.org/10.1101/2025... We have improved DELSSOME and showed that we can accelerate the estimation of two new biophysical models. By collating 12,005 individuals, we derive normative trajectories of cortical E/I ratio across the lifespan ...

Very happy to share our paper on the "summer slide" in kid's cognitive test scores is out now in @pnas.org! We find a replicable dip in performance across multiple domains of cognition in >23,000 kids across 4 datasets! Check out the 🧵 from @ariellekeller.bsky.social below! 👇

Our paper on the ☀️ "summer slide" 🛝 is out now @pnas.org! www.pnas.org/doi/10.1073/... Summer slide is a replicable phenomenon across diverse datasets that's more than "forgetting" school material in vacation months, but effects of socioeconomic inequality are ➡️ 7x bigger! ⬅️ #PsychSciSky #DevPsy 🧵👇

Is the “standard workflow” holding back fMRI analysis? Mass-univariate analysis is still the bread-and-butter: intuitive, fast… and chronically overfitted. Add harsh multiple-comparison penalties, and we patch the workflow with statistical band-aids. No wonder the stringency debates never die.

I can't recommend this fantastic new review from @valeriejsydnor.bsky.social enough! It does an amazing job of synthesizing the current state of the literature and then looking forward to provide a fresh perspective on how to move this work forward in humans. Check it out!

OK, It is not just the HBCD release... docs.hbcdstudy.org It’s the ABCD Release time too! docs.abcdstudy.org nbdc-datahub.org That means the ABCC 3.0.0 is live!!! The largest release yet from the ABCD-BIDS Community Collection. This is going to be fun!! 👇 Let’s dig in.

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back. This was the largest political gathering in Denver since Obama in 2008. Also bigger than the 2024 DNC. And the largest ever rally in Bernie’s career (and obviously, mine too).

For those who don't know, here are very real research costs that directs cannot cover - all fall within indirects: the buildings we work in (upkeep, maintenance, cleaning, etc), utilities, IT infrastructure, human resources, administrative staff, security, and lots more

The new NIH policy for indirect costs going forward is capped at 15%. This is forever going to alter the science ecosystem, upending and destroying a number of programs at universities across the country. grants.nih.gov/grants/guide...
