Pregnancy loss is common in humans, and chromosomal abnormalities are the leading cause. Using genetic data from ~140,000 IVF embryos, we show that maternal variation in meiosis genes influences recombination and aneuploidy risk.

Come join us in beautiful Britanny, France in May 2026 for a workshop that I am organizing with @lucievirevolte.bsky.social and @psudmant.bsky.social on Rapid host adaptations to infections:

Huh, cool, does each polymerase only replicate its own linear plasmid? Is there a part of the polymerase protein that’s rapidly evolving that could be defining the specificity?
Happy to share the final story from my thesis, demonstrating that the common ancestor of all terrestrial fungi had zymocin-like killer plasmids, a toxin system found in some budding yeasts. Come with me on an all-too-familiar, database dumpster-diving journey (1/10)

✨ Latest exciting story of the group in @nature.com. Here, we go beyond SNPs and built a species-wide atlas of genetic variants in yeast. With >1,000 near T2T genomes, we show how large genomic variations affect trait diversity.

EUCLID: …thus, there does not exist a rational number whose square is equal to 2.
HIPPOCRATES: [grumbling] I fail to see the clinical relevance of any of this
Final version of our paper out now on how high-throughput methods can be useful for answering everyday “low-throughput” genetic questions!
The 90s was more my radio era than albums, but I’d say each of these are perfect in their own way: RATM, Midnite Vultures, Rangeela, Blackout! (Would have also said 2001, but the skits are terrible.)
Now out officially, with the entire kit on @addgene.bsky.social. Great collaboration with @merusadhu.bsky.social, with more to come.
What did you think of Gyokeres? Didn’t seem very threatening. Could just need more time to bed in.
Microscopy images showing that correct localisation of either Ktd1 or Snc1 requires the COG complex.
Kamilla Laidlaw, Hatwan Nadir, Chris MacDonald @yorkyeast.bsky.social and team @biologyatyork.bsky.social discover that killer toxin K28 resistance in yeast relies on COG complex-mediated trafficking of Ktd1.

I’m really rooting for this approach to catch on! Of the papers I’ve been involved in, this is probably the one I most feel is contributing a different way of thinking. Big shoutout to the co-first authors, Molly Monge (now an MD/PhD student at Cornell) and Simone Giovanetti.
“High throughput” doesn’t have to mean hard/expensive! At its heart, the difference is that instead of picking a few clones of your transformation, you take all the colonies. And with low sequencing costs and the possibility of pooling sequencing, it will generally be affordable.
Second, background mutations. Often in low-throughput approaches, each strain is generated once and split into replicate cultures for experiments. It makes the experiment a lot easier, but any background mutations are shared between replicates! Again, bulk methods can help!
First, replicates. It’s hard to do low-throughput experiments on even a modest number of samples with more than a small number of replicates per sample. Not a problem if you make your replicates in bulk using barcodes and test your hypothesis in high throughput!
New paper from my lab! We describe our idea that high-throughput pooled experimental methods – typically used to test thousands of hypotheses at once – also have huge potential to help in “everyday” experiments testing one or a few focused hypotheses. Why? Two reasons: doi.org/10.1093/g3jo...
