Hello #Chemtwitter! New year, new lab, and now also with a new website: systemschemistry-lab.chimie.…
Check out for what @GuilleMonrealS and myself are up to in the Laboratory of Systems Chemistry :)

PhD alert! I have two ERC-funded PhD positions to uncover the chemical origins of life! Starting date: October 2025. *UK fees only*. Projects described here: lclu.cam.ac.uk/studentship-o…
Email me if interested - deadline (PhD in Biochemistry, Uni of Cambridge): January 7th!
And now with a free read-only link, courtesy of Nat Chem: rdcu.be/d1S5C
Check out how @OttoLab got a beginning of Darwinian evolution with purely synthetic chemical systems!
And the last of 3 @OttoLab papers within 24h!
Biological principles are valid only for biological systems? Don't bet on that. We found synthetic replicators literally dying out when in competition, or coexisting if they have different food preferences.

Our task: finding out why one replicator grows slower than the other (and dies out). It turned out both stick together (seen in TEM by @Armin__Kiani) and inhibit each other, one loosing access to food and thus not growing any more. Being starved by its competitor, literally!

@Juntian74804617 's food binding experiments show this is probably due to that replicator having a more hydrophobic surface, which would make it hide inside the aggregates, away from food. Other replicators don't bind the same food, so there is coexistence instead of competition.

This said, I invite you to follow me for news & updates on that better Twitter called BlueSky (bsky handle displayed here next to my name) - will cease activity here in due time!

And because it's better to be two than lonely, I will team up with my pal @GuilleMonrealS to form an independent (or rather co-dependent?) research group with my new position. Exciting times coming ahead for systems chemistry in Strasbourg!

Why do I look happy here? Sure, Verona is a beautiful city, but mostly because...
... from 1st of December on it will be "Monsieur le Professeur". Got a tenure-track at UMR7140 Chimie de la Matière Complexe, in my beloved Strasbourg - I couldn't ask for more!
My deepest gratitude to all my mentors: Stéphane Bellemin-Laponnaz & Thierry Achard, @OttoLab, @MoranLabChem, and to numerous friends & colleagues who accompagnied and encouraged me on this journey. Without you I wouldn't have made it!

Delighted to share a new series of the adventures of the unique metabolite phosphoenolpyruvate (PEP). Check out our latest paper from @MoranLabChem just accepted in @angew_chem on the study of alkene hydration, a key mechanism found in core metabolism: onlinelibrary.wiley.com/doi/…

Conference Organizers: If your origin of life research conference isn't listed on our new page, we'd love to hear from you. Please reach out and let us know so we can include your event. Let's keep the community informed and connected!
🌟 Exciting News! 🌟 We've just launched a brand new page on the OoLEN website dedicated to listing conferences in origin of life research. Stay updated on the latest events and connect with fellow researchers! 🔗 oolen.org/news-and-events/li… #OriginOfLife #ScienceEvents #OoLEN

Our Institute has an opening for a junior group leader, in any area of chemistry: shorturl.at/NtE9F
That's how I started my group, and I think it's a wonderful opportunity.

What can dissipative chemistry bring us? In our recently published paper, we demonstrate the emergence of mechanical function from disspative droplet systems. @NatureChemistry nature.com/articles/s41557-0…

If you want to know more about key mechanisms at the origin of a protometabolic reaction network and its complexification toward biochemistry, check out our latest review in ACR @ACSPublications : pubs.acs.org/doi/10.1021/acs…
Big thanks to @EmilieWerner7, @s_sodei & @MoranLabChem
