Really excited for @yundeng.bsky.social's nice work to come out. As Yun details in his thread 👇, we wanted to develop a "recipe" for getting time-stratified versions of population genetics statistics from ARGs. We end up with interpretable, time-specific versions of the GRM and various f-stats. 🧬🧪

The first manuscript from my postdoc is out (doi.org/10.64898/202...)! We introduce 𝐭𝐢𝐦𝐞-𝐬𝐭𝐫𝐚𝐭𝐢𝐟𝐢𝐞𝐝 𝐬𝐭𝐚𝐭𝐢𝐬𝐭𝐢𝐜𝐬 for studying population structure change over time, with the temporal resolution of Ancestral Recombination Graphs (ARGs). Joint with @jkpritch.bsky.social and @jeffspence.github.io. 1/n

I don't think so. All universities sell their big appointments, and that story was done pretty much overnight. Ultimately, it's a uni job. Nobody gives a fig. The only reason why a cheat at Cambridge made these vast waves was because the cheat was black. White cheats wouldn't and haven't.

The reason the world is burning is that decision-makers have spend the last 40+ years listening to the minimisers, delayers and obstructionists saying that the climate crisis doesn't need urgent attention They should really stop listening to those voices now

Looking forward to #Dros26 this week. My lab is recruiting and I would be delighted to chat with anyone interested in grad school/postdoc positions in evolutionary cell biology and developmental genetics. Please reach out if interested!

Congrats @jeffgroh.bsky.social et al. Some avocado trees open female-phase flowers in the morning & then male in afternoon. Others show complementary pattern (m->f), to synchronize pollination of two types. Jeff show this to be a >45Mya polymorphism at a transcription factor across 100s of species.

In honor of @alyssa-phillips.bsky.social new preprint, here's me standing in her common garden taking a photo op to troll her with all the grass species in the plot that are *not* big blue stem.

Super proud of @alyssa-phillips.bsky.social 's paper, now out on biorxiv! She resolves the origin(s) of polyploid big blue-stem, a dominant species in the midwest tall-grass prairie. Her common garden analysis also informs on environmental adaptation and hints at the impacts of polyploidy.

Sharing our new paper, "Distinct haplotypes and reversed dominance at a single-gene balanced polymorphism controlling heterodichogamy in two genera of wingnuts". Genomics & evolution of a mating type system involving two morphs with alternating sexes in walnut relatives www.cell.com/current-biol...

Distinct haplotypes and reversed dominance at a single-gene balanced polymorphism controlling heterodichogamy in two genera of wingnuts

In most species within the walnut family, two genetically determined morphs alternate between male and female flowering phases in time. Groh et al. identify a distinct locus for this dimorphism in two...

In these dark times, it comes as a rare pleasure to highlight @natanaels.bsky.social ‬ & @marcdemanuel.bsky.social's work on germline and somatic mutations in humans. 1/n www.biorxiv.org/cgi/content/...

Collateral mutagenesis funnels multiple sources of DNA damage into a ubiquitous mutational signature

Mutations reflect the net effects of myriad types of damage, replication errors, and repair mechanisms, and thus are expected to differ across cell types with distinct exposures to mutagens, division ...

1. The philosophy of science sometimes gets an unearned reputation as a purely academic exercise that offers little by way of concrete tools for advancing research. This is wrong. And today, as we grapple with how AI is changing the nature of scientific activity, it's desperately wrong.

It is depressing, but all too predictable, how swiftly we’ve gone from the Social Science Genetic Association Consortium offering reassurances about the uses of behavioural polygenic scores to one of their lead authors marketing embryo selection for IQ

Text from an FAQ in Okbay et al 20222: https://www.nature.com/articles/s41588-022-01016-z a similar same statement is made in an FAQ in 2025: https://www.biorxiv.org/content/10.1101/2025.05.14.653986v1.supplementary-material Text reads: "The results of SSGAC studies have sometimes been used by online platforms, including some companies, to predict individual outcomes. We recognize that returning individual genomic “results” can be a fun way to engage people in research and other projects and to feed or stoke their interest in genomics. But it is important that participants/users understand that these individual results are not meaningful predictions and should be regarded essentially as entertainment. Failure to make this point clear risks sowing confusion and undermining trust in genetics research"
