- Reposted by Nicholas JuddNow in press one of my last PhD projects! We traced the neurobiological profile of fMRI BOLD signal variability, a measure that has been related to age, behaviour, disease status, but had not yet been fully contextualised within the brain's multiscale architecture. www.nature.com/articles/s41...
- Reposted by Nicholas JuddThere are also meaningful differences in school proximity to hazardous sites by state. Even among states with similar site and population densities, the share of sites located near schools varies, suggesting the influence of local policy and land-use decisions. 5/

- New personal record of desk rejects 🥳 I am taking a note of journals that take over a month for the desk 📖 It is also a unusual situation where pretty much everything has been already reviewed at eLife on our Neuro paper (click for open reviews), now the sample size is just substantially larger.
- New paper by @njudd.com shows that an additional year of education doesn't causally affect telomere length in old age, despite many (theory) accounts arguing otherwise. It's been desk rejected by 13 journals happy to publish small 'positive' telomere studies. Sigh. www.biorxiv.org/content/10.1...
- Lots of prior work has related longer telomeres to a host of positive lifestyle factors - with often the explicit hx that engaging in these behaviors will slow down biological aging (aka build a cognitive reserve).
- As mentioned by others (Rentscher et al., AnnRev, 2020) the vast majority of this work isn't even longitudinal. It is just people cross-sectionally relating telomere length to [insert your favorite IV]. Our paper is (to my knowledge) the first natural experimental design on telomeres.

View full threadA similar effect happens for telomeres, yet 13 editors agreed it shouldn't get past the desk. Possibly it was seen as narrow in scope, yet education has one of the largest confounded effects with aging biomarkers. If this is happening for education... Mediterranean diets, etc watch out.
- Reposted by Nicholas JuddGreat post! I just read this paper by @drewhalbailey.bsky.social and colleagues that shows the RI-CLPM also performs better than CLPM when there are unmeasured time-varying confounders: psycnet.apa.org/record/2025-...
