If someone you know buys into claims about "genetic optimization" of embryos using polygenic scores of cognition, just send them our 2024 paper on Beethoven & musicality. We wrote it to help communicate limits of individual-level genetic predictions & complexity of links between DNA & behaviour. 🧪👇

In #GENETICS, Williams et al. present a novel statistics—haplotype score—for summarizing identity-by-descent (IBD) sharing that can distinguish half-sibling pairs from avuncular or grandparent-grandchildren pairs and assign individuals to ancestor vs descendant generation. buff.ly/SaZP3CA

Yay! @genomeofforrest.bsky.social work published today in PLoS Genetics. Forrest took a large maize common garden dataset and asked whether Environmental GWAS was actually useful for predicting which individuals would have highest fitness. Turns out, the answer is no. 1/2

We currently have a call for support that has gone out to European labs, to support FlyBase-UK. We are asking our colleagues from labs in the US and other countries to wait for a similar call to them that will go out in the near future, to support the US sites. We thank you for your patience.

The rest of Mendel's alleles characterized! So, out of 7 traits, 3 caused by TE insertions!!! (though apparently there are two different green alleles, one cause by a TE insertion, but another a promoter deletion allele) www.nature.com/articles/s41...

Fun collaboration with Mélodie Bastian and Nicolas Lartillot. Pi_S and Pi_N/Pi_S extracted from genome assemblies follow nearly neutral predictions across 150 mammals. Getting closer to getting the constraint controls needed to detect ancient epidemics mammals-wide. www.biorxiv.org/content/10.1...

I wrote about how population stratification in genetic analyses led to a decade of false findings and almost certainly continues to bias emerging results. But we are starting to have statistical tools to sniff it out. A 🧵:

I am running my statistical rethinking course again starting in January. But this time just for Leipzig locals, so I can work with a smaller group this year and track individual progress better. I think that will help me tune the material, espeically homework, better. Materials still open however.

La #FNSEA rejette la science agronomique et plonge dans un obscurantisme dangereux pour les agriculteurs, prônant des pratiques agricoles obsolètes basées sur un usage incontrôlé de #pesticides et d'engrais chimiques. Je dénonce cette action et appelle au respect des chercheurs de #INRAE

Une enquête passionnante, richement documentée et très instructive sur la catastrophe écologique et sociale que le remembrement a entrainée, ainsi que sur le contexte politique de sa mise en œuvre. Plus que jamais d'actualité !

Indeed, fascinating to think that we have attendees from all over the globe, from North America to South Korea, and from Sweden to South Africa. Such a wide range of longitudes & latitudes, perfect for our course on landscape genomics this Friday (lecture+tutorial with @bourgeoisyann.bsky.social)!
