Hope she wins the science fair. What a wonderful thing to see today!

Was she the one with the study of glue strength? If so, tell her she is amazing!

Round two. Let's go!

Thanks for your reporting.

White House stalls release of approved US science budgets The US Congress rejected sweeping cuts to science agencies. But the NIH, the NSF and NASA have had their spending slowed.

Congress rejected massive cuts to US science budgets for 2026, but much of the money still isn’t flowing to researchers.

The culprit? The White House Office of Management and Budget (OMB) is quietly slow-walking the release of funds. 🧵👇

The Call for Abstracts has been extended until March 2nd, and we're excited about building an engaging scientific program. We hope you'll consider submitting your work, and hope to see you in June!

Approval of new members takes years. The HHS Secretary (RFK Jr) can select members, and these selections would not be subject to the vetting process.

Exclusive: key NIH review panels due to lose all members by the end of 2026 Thirteen of the agency’s advisory councils, which must review grant applications before funding is awarded, are on track to have no voting members.

As things stand today, all NIH institutes will have empty advisory councils by the end of 2026. NIMHHD will have an empty advisory council in 1 month, NIMH in 8 months.

Foundations of Item Response Theory This workshop from Wes Bonifay focuses on the foundations and application of item response theory, particularly as applied to binary items.

I'm optimistic about where the new leadership will take us, too!

Seriously, wow!

Woo hoo! Congratulations Miri!!

Thank you for sharing!

That is gorgeous. Is it your own recipe or can interested followers find it published somewhere?

Completely. I'm not a parent, but I have tremendous sympathy for parents of over-scheduled kids, and parental overwhelm seems like reason enough to back off.

'Tis the season (for collider bias)! Check out Michel's very nice simulation and explanation of why you shouldn't pull your kid out of varsity chess club just yet.

Incredibly!

And if you're interested in this kind of work and looking for a postdoc position, we are hiring! Please see the ad on my website, linked from my bio.

Thanks to my trainees Amna Asim, Yuan Yang, coauthors @toddlencz.bsky.social, @seanclouston.bsky.social and others not on Bsky. And thanks to the @quantitude.bsky.social podcast, whose collider bias episode provided solace and validation in the middle of the peer review process. 6/6

Check out the paper for demonstrations of this effect in simulations and three datasets. We need to understand how PGS perform in clinical settings if they are ever to be useful as predictive markers, which is what we are trying to accomplish with the FEP-GEN consortium. 5/6

Collider bias also skews associations between the BP PGS and clinical outcomes like remission and recovery. The BP PGS is associated with lower odds of remission (OR=0.79) and recovery (OR=0.86) in the general population, but positive (ORs=1.19 and 1.2 but nonsignificant) among cases. 4/6

Selection therefore becomes a collider, and conditioning on the collider (implicit in case-only analyses) attenuates the correlation between the SZ and BP PGS. 3/6

The schizophrenia polygenic score (SZ PGS) and BP PGS are fairly strongly correlated. Both contribute to a person’s risk of developing a psychotic disorder, and being selected into a first-episode psychosis cohort. 2/6

Have you wondered why higher bipolar polygenic scores (BP PGS) seem to predict better outcomes among people with psychosis? Here’s why (1/6) 🧪#PsychSciSky

Making the rest of us 365 folks look like bums!

CDG3 is out, with better-than-ever resolution of the genetic structure of psychiatric disorders.

Splitter trolling at its finest.

Brilliant.

Can't wait to read! And clarifying the "syndrome" level is huge, which can't be done with dx data.
