We found a globally rare variant rather common in Estonia that rises BMI by 0.8 units per allele 🤯 @estbiobank.bsky.social
Uuringus, mis põhineb Geenivaramu andmetel, avastati mitmeid olulisi geneetilisi variatsioone, mis mõjutavad kehamassiindeksit (KMI). doi.org/10.1038/s414...
Characterization of prevalent genetic variants in the Estonian Biobank body-mass index GWAS - Nature Communications
Here the authors perform a genome wide association study of 204,747 Estonian Biobank participants revealing 214 BMI loci. Reported signals include ADGRL3, PTPRT, and a protein-truncating POMC variant ...

Do you have experience turning amateur data analysis scripts into robust, scalable code? I’m hiring (hourly pay) to professionalize Python scripts for scientific data analysis, making them reusable across multiple datasets.
Tromsø/Norway-based candidates preferred, but all are welcome! DM me!

@filipkmorys.bsky.social et al. Always digging deeper🤓
Obesity increases the risk of Alzheimer’s disease, yet it remained unclear whether #obesity causes #neurodegeneration through the same mechanisms. A new study by Filip Morys in the lab of Alain Dagher used #OpenScience brain data to find the answer.

I'm very excited that this is out as preprint. In this study, 370 participants completed up to 30 runs of reward learning. We see that BMI and and Binge eating are associated with distinct RL patterns. Includes hierarchical models using Stan (+ many hours of sampling) and MRI data of an effort task
Our big behavioral precision mapping preprint is out. Based on 1,486,950 observed choices in a reward learning task, we show that BMI is associated with higher and more variable learning rates. Binge eating was associated with lower reward sensitivity. #neuroskyence 🩺

A flood of scientific papers making misleading #health and #nutrition claims is probably the product of artificial intelligence tools scraping openly available data, researchers warn. nature.com/articles/d41... #AI #PaperMills
AI linked to explosion of low-quality biomedical research papers
Analysis flags hundreds of studies that seem to follow a template, reporting correlations between complex health conditions and single variables based on publicly available data sets.

New paper! In ~30k people from UKBB we show that ultra-processed food consumption 🍔 is associated with structural integrity of feeding-related brain regions (Hpth/NAcc) 🧠 Some of the changes occur independent of obesity, through inflammation. www.nature.com/articles/s44... @alaindagher.bsky.social
