Have you ever wondered 🤔... Does phenotypic variance respond to environmental perturbation? Does it have a genetic basis? Are mean and variance regulating loci exposed to different selection pressures? These and more questions are explored in our new preprint 🔥 www.biorxiv.org/content/10.6...

Our most recent work on the “function and evolution” of #nuclear-speckles is now online at Cell @cp-cell.bsky.social doi.org/10.1016/j.ce... Read the thread👇 for the highlights of our findings.

New Perspective!🔥It's fascinating how scientists from different fields but interested in the same question [e.g. genotype-phenoytpe relationship] can have such different perspectives. Here we put in our 2 cents wrt genetic effects being context-dependent, and pheno variation being mostly polygenic

For starters, there's not "one weird trick to ditch your X." There are multiple paths to sex determination turnover. To read more about it, including what genes were gained or lost and how the genome looks in X chromosome scales, check out our preprint: www.biorxiv.org/content/10.6... 6/n

How could a simple self-replicating system emerge at the origins of life? RNA polymerase ribozymes can replicate RNA, but existing ones are so large that their self-replication seems impossible. Could they be smaller? Excited to share our latest work in @science.org on a new small polymerase. 1/n

For once an article about the "how to get to Rome" and not "Rome" itself. Collaboration with my "partner-in-crime" @felibas.bsky.social has been a key ingredient of my research over the years. Sara Miller at Molecular Cell spoke with us of how we got there and what we think about collaborations.

A sex-determining gene region in ants, bees, and wasps has maintained its function for over 150 million years through its chromosomal position rather than its DNA sequence, as evidenced by the lack of sequence homology among lineages. In PNAS: https://ow.ly/n9eU50XWipU

Great new paper! Many stinging wasps, bees, and ants have controlled the sex of their developing eggs for millions of year using an ancient segment of their genome- always the same segment- but what's weird is, *the exact DNA sequence of that segment doesn't seem to matter*.

🚨New paper from our team on our favorite sex locus ANTSR! 🚨New collaboration with @hugodarras.bsky.social , led by our talented @chuanxinyu.bsky.social, we show that ants, bees and stinging wasps share an ancient sex locus, a suspicion we had when we first found the locus in the Argentine ants!

How do new centromeres evolve while staying compatible with the division machinery? Discover it in our new Nature paper! We show centromeres transition gradually via a mix of drift, selection, and sex, reaching new states that still work with the kinetochore. 👉 doi.org/10.1038/s41586-025-09779-1

"When the female bugs lay their eggs, they rub the cultivated hyphae across the egg mass. The hyphae grow to envelope the eggs and physically exclude attentive parasitoid wasps until the bugs hatch." #fungi #symbiosis
