1/ Can AI help researchers check whether published social science results actually reproduce? In our new PNAS paper, we tested this directly in the AI Replication Games: 288 researchers, 103 teams, and real replication packages from quantitative social science.

After nearly a decade at the University of Nottingham, I’ll be moving on this summer. As of July, I’ll be returning to Canada to take up a position at MacEwan University in Edmonton.

Thrilled to share our paper on the formation of brain shape in human newborns, just out @natneuro.nature.com: tinyurl.com/2ty4ef43 Using #fractal analysis of #MRI data from the developing Human Connectome Project (lnkd.in/dxeHbJX6), we show that brain shape closely captures infant age and genetics ⬇️

About 10 years ago I came across 'fractal dimensionality' as a measure of brain structure. Studying it's utility with healthy aging, clinical populations, and across species has led to 19 papers since then. The most recent paper is now online at Nature Neuroscience! www.nature.com/articles/s41...

You can do this right now: Think of a person who wrote a paper you love, whose work influenced or helped you, or has made your professional life better. Search up their email address. Shoot them a quick email of thanks. It means so, so much. This is a rough time of year, share some joy.

Three Surprises From Attempting To Replicate Recent Studies in Top Psychology Journals
Amanda Metskas
December 4, 2025
How has the replication rate of psychology studies changed in recent years? 

Are we still experiencing a “replication crisis,” where only 40-60% of results replicate when the study is conducted again?

Straight off we see the impact of changes to student visas, in particular restricting dependents. Student visas are limited terms though, meaning including them in overall stats tends to skew them, but makes an easy "win" for a government looking to reduce immigration. 2/ www.gov.uk/government/s...

“Ablation” was originally introduced into AI with the correct sense (removing a component). But in the last 5 years, its meaning has expanded to “sensitivity study”. As a reviewer, I insist on the correct usage.
