Diffusion MRI (dMRI) is a powerful tool to study white matter maturation. In our new preprint, we process and distribute a new resource of >24,000 ABCD dMRI scans using open source tools! We then evaluate how methods shape inferences about development.

Make healthier food choices can be confusing and challenging.
A study led by Michael Essman (@duke-university.bsky.social) whilst at @imsepidemiology.bsky.social (@cam.ac.uk) examines how we understand ultra-processed foods and the decisions we make about them.

I need you to understand that thereβs actually one very big reason making up a huge part of why everything sucks now: monopolies. Or, more accurately, oligopolies.
Thatβs why so many people are excited about the Ticketmaster decision that just happened.
But itβs the tip of the iceberg:
Are different desires (e.g., food, sleep, alcohol, cannabis) experienced and regulated the same way? We tested this question in a new preprint with Yang Liu, @minzlicht.bsky.social, @wilhelmhofmann.bsky.social, and @kevinmking.bsky.social: osf.io/preprints/ps...
In a first last month, renewables supplied more power to the U.S. than natural gas, a milestone in the shift to clean energy.
White matter pathways mediating dorsolateral prefrontal TMS therapy for depression
New @natneuro.nature.com paper led by Caio Seguin, Robin Cash, and Andrew Zalesky.
We map (indirect) pathways from DLPFC to SGC and link individual variation with response efficacy.

A single line in this piece just made my day:
βThe electricity system operator is understood to be preparing to run the grid without any gas for short periods as soon as this summer, in a first for the UK energy system.β
Renewables *work*. And progress mattersπ

Let me say this plainly: Iranian children have as much of a right to live and thrive as American children.
Their babies MUST be as precious to me as my 6 niblings and my baby grandnib are IF I want them to have a future.
If I want a future for my kin AND humanity, I MUST act like it.
So must you.
How do we define "good" fMRI data? Especially with resting state, there are circularity risks if we evaluate data quality as showing the networks we expect to see. Javier Gonzalez-Castillo (& me & others) developed pBOLD, a new metric that uses multi-echo info. www.biorxiv.org/content/10.6... 1/8
Hard agree. I think the other issue is how easy it is to get these meds through online providers where there is minimal screening and accountability to ensure ppl are not lying just to access meds.
Food policing poor families isn't a win for nutrition--it's a loss for dignity and joy.
As Brea Perry and I find in our research (see reply), low-income parents buy food treats for their kids because they want their kids to feel happy and normal--and they can't afford to do so in bigger ways.
I wish my fellow Ontarians would remember this at election time rather than swallowing the long-disproven myth that it's progressives who are bad with money.
Our latest work looking at the neuroanatomical basis of impulsivity in youth is out now in Molecular Psychiatry!
The answer: no. Estrous phase had no association with cocaine intake during short access, long access, or progressive ratio sessions. High vs. low estrogen groupings? No difference. This is a null finding and null findings matter. But the story gets far more interesting.

Absolutely. Even things like change over time as a result of food/calorie tracking - which I would assume would impact nutrition/calorie estimates
This is really neat. It would be interesting to look at how health washing impacts these judgements (as in foods marketed as healthier alternatives but in reality are just as calorie dense/lack nutrition)
see?
here's the thing. A lot of people are like, the earth is fucked, it's beyond salvation, it's hit the tipping point, but time and time again we see that if we just fucking fixed the problem, it rebounds so incredibly fast. Imagine what could be done if people actually cared

My issue is that this call is specific for professors. Canada is already losing young talent and this will pus them out even more. Investing in the next big names would keep innovation and talent in Canada
Do researchers share their code upon request? Does running their orginal code on the original data produce the original results? We provide evidence in a new Royal Society Open Science publication. Studying more than 1,000 articles which use data from the European Social Survey, we find that... π§΅
