Clinical trial reforms that once seemed radical How randomized controlled trials, preregistration, and results reporting became standard practice.

The idea of the need for a control group may have been radical at the time, but trust me it's now generally accepted. This is not some fringe believe by methodological hardliners; it's established practice.

Reviewer notes: In a randomized experiment, the pre-post differences are not effect estimates Reviewer notes are a new short format with brief explanations of basic ideas that might come in handy during (for example) the peer-review process. They are a great way to keep Julia from writing 10,0...

P.S. Pre-post differences are *not* valid treatment effect estimates. Why? Here's a post by @statsepi.bsky.social: statsepi.substack.com/p/one-simple..., here's a post by me: www.the100.ci/2025/01/22/r... >

We think of white matter as the highways of the brain. But when we followed development along those highways, we were surprised. The journey is more complex than we thought. My final PhD paper, “Two Axes of White Matter Development”, is now out in @natcomms.nature.com! 🛣️🧠✨

Ecstatic about my science AND art being featured in @biologicalpsych.bsky.social CNNI's current issue with @northernthrux.bsky.social painting on the cover and our exciting @theabcdstudy.bsky.social article completed with @catherinealebel.bsky.social www.biologicalpsychiatrycnni.org/current

A "methods primer" article in the journal "BMJ Medicine", titled "Factors associated with: problems of using exploratory multivariable regression to identify causal risk factors"

We wrote an article explaining why you shouldn't put several variables into a regression model and report which are statistically significant - even as exploratory research. bmjmedicine.bmj.com/content/4/1/.... How did we do?

YouTube video by HiTOP Using HiTOP in Research

We’ve just published another video on HiTOP that tries to flesh out a bit more how the framework can be helpful in research: youtu.be/q0jOi_Nl1yo

We hope it’s useful, and are keen to hear any feedback

Thanks again so much to @tashtc.bsky.social for all of her hard work creating this video series ✨

Lifespan Trajectories of Asymmetry in White Matter Tracts | bioRxiv www.biorxiv.org/content/10.1...

Authors retract Science paper on controversial fMRI method Several MRI artifacts contribute to the neuronal activity signal picked up by the method, according to a preprint the authors posted this month.

A method for capturing neuronal activity using fMRI excited the neuroimaging field but couldn’t be replicated. Today, the authors of the original paper retracted their work.

this is wild - i was aware of Mary-Claire King's absurdly important discoveries on BRCA / inherited breast cancer but I had no idea that her first PhD paper (King & Wilson 1975, Science, not bad lol) is the "99% of protein coding shared btwn chimps and humans" result

What Is the Fourier Transform? | Quanta Magazine Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform,…

The Fourier transform is everywhere you look. It has helped scientists to study tides, detect gravitational waves, and develop radar and MRI technology. Here’s how it works.
