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

Very last chance to join us (Deadline tomorrow Feb 10!) at this Developmental Biology meeting! Have a nice story? Come and discuss it with editors from @embojournal.org @plosbiology.org and @dev-journal.bsky.social ! A one hour info session from @erc.europa.eu will also be presented!

Donc si vous êtes une femme scientifique et que vous êtes co-autrice d’un joli papier publié récemment, ou alors que vous avez juste vu un super papier dans votre domaine, faites-moi signe 👋

🚨NEW PAPER 🚨 #Caecilians maintain a functional long-wavelength-sensitive cone opsin gene despite signatures of relaxed selection and more than 200 million years of fossoriality, published in Evolution @sse-evolution.bsky.social academic.oup.com/evolut/artic...

Organizing an intensive writing day for a group of experienced & junior scientists!Goals are to outline manuscript, agree on questions/hypotheses, draft sections, start analysis. Team will be split into outlining/writing + stats/analysis group. Tips for max progress & momentum after?

New paper presenting rather compelling evidence that the stem-vertebrate Haikouichthys had paired lateral and supranumerary medial eyes (!!!), and proposing that the medial eyes may have deep homology with the pineal and parapineal organs. www.nature.com/articles/s41...

Bird retinae are among the most oxygen-hungry tissues known, but they do their stuff entirely anaerobically, thanks to a structure called the pecten. This paper in @nature.com also contains the most antique citation I've ever seen www.nature.com/articles/s41...

Why does life explore so few of the forms it could possibly take? Using fractal descriptors, this #scienceadvances paper shows that Earth’s biosphere clusters around simple shapes, reflecting deep evolutionary constraints. @artemyte.bsky.social @manlius.bsky.social www.science.org/doi/pdf/10.1...

I explained the dangers of the recent politicization of grant reviews at NIH for The Hill, and also that while diversity otherwise remains a bad word, geographic diversity is somehow laudable. thehill.com/opinion/tech...

I am very happy (and a bit scared) to present to you what we have been working on over the last 4 years. This manuscript is exactly what I dreamt of when I started the lab and I could not be happier and prouder of the outcome!

In mammals: 🧠 A liver looks transcriptionally like a liver, even across large evolutionary distances. In plants: 🌱 A leaf from one species can be transcriptionally closer to another organ in the same species than to a leaf from a distant species. This fundamentally changes how body plans evolve.

🧵 Just out in Cell after more than 10 years in the making! 🎓 www.cell.com/cell/fulltex... Plants and animals evolve radically different body plans. Do they also operate under fundamentally different molecular evolutionary constraints during organ formation? @cellpress.bsky.social

Exciting news to start the new year! We’re thrilled to see this work finally out in @natecoevo.nature.com, the result of a major collaboration between my lab and the labs of Veronica Hinman and Nacho Maeso, began many years ago with the dear José Luis Gómez-Skarmeta. www.nature.com/articles/s41...

Aligning different spatial omic data (histology, spatial proteomics, spatial transcriptomics, etc) is challenging. PhD students André Forjaz and Valentina Matos Romero developed PIVOT to do this really well and rapidly. Read about PIVOT here: www.biorxiv.org/content/10.1...

#WntA is a crucial marker of stripe elements early in development for the Nymphalidae butterfly family. @jasminealqassar.bsky.social & co explore if WntA has maintained its role in stripe elements over 95 million years of evolution in the Hesperiidae family of butterflies. doi.org/10.1242/bio....

🚨 What if evolution is the ”law”… and networks are the machines that do the work? In this paper (just published) I try to formalize how living systems are non-equilibrium, information-processing, adaptive matter. With a great biological flavor! 🧪🌐🌍🧬🦠 👉 iopscience.iop.org/article/10.1... 🧵 1/

Grading and googling hallucinated citations, as one does nowadays, and now that LLMs have been around for a while, I've discovered new horrors: hallucinated journals are now appearing in Google Scholar with dozens of citations bc so many people are citing these fake things

NSF - Forced reorg - POs down ~ 40% (DRP, most rotators not renewed, retirements) - Forced move (and we have to pack and clean) to a building with no furniture, little to no conference space for panels, inadequate 🛜, …) I personally love the boxes they gave us for packing. “Details matter” 🙃
