Selection for photocatalytic function through Darwinian evolution of synthetic self-replicators - Nature Catalysis Darwinian evolution has shaped life on our planet through natural selection. Here, the authors report on the combination of self-replication, mutation and protometabolism in an out-of-equilibrium abio...

Congrats Claudia! That's great news!

Past and present collide as @rjmayer.bsky.social and @yannickgeiger.bsky.social, now both leading groups of their own, meet @noeminogal.bsky.social at @esor2025.bsky.social in beautiful Padova.

Just starting at #ESOR2025 in Padova. This is the first time I get a booklet about liqueurs at a conference, incl. cocktail recipes...! 🍸

That looks very cool Alex! That kind of first-principles work that we need to guide the design of new systems 💡

Stoichiometric recipes for periodic oscillations in reaction networks Oscillatory chemical reactions are functional components in a variety of biological contexts. In chemistry, the construction and identification of even rudimentary oscillators remain elusive and lack ...

Our new preprint 📑 about oscillating chemical reactions ⚗ just came out! arxiv.org/abs/2508.15273
We introduce tools 🛠️ that expand the scope of oscillators that can be analyzed, and use them to extract a lot of new qualitative and quantitative insights about oscillating chemical reactions! 1/3

Reminder! Only few days left to apply for this nice opportunity to do a PhD with us.

Pumping molecules against a gradient without a pump?

Back-to-back with @boekhovenlab.bsky.social, we describe minimal systems that use chemical energy to transport molecules against a concentration gradient.

It started with a little shock!🧵

A second position (PhD or post-doc) will open in the course of the following weeks. Stay tuned!

Job Alert 📢📢📢 Systems chemistry lab is hiring! We are looking for motivated candidates to do a PhD with us. It will be on the effect of (large) aggregation on chemical reaction networks, more details here: systemschemistry-lab.chimie.unistra.fr/vacancies/. Repost very much appreciated 🙏

How can a cell control the size of its organelles?

Excited to share a mechanism to control droplet size we recently found.

A post-doc position in a very nice group & institute (I was there just two weeks ago) - apply, especially if you look also for a long-term position!

Super happy that this important issue has found its way to IUPAC. If you are, even remotely, concerned by out-of equilibrium systems and/or molecular machines, please read this article and answer the polls!

Timed Formation and Aging of Complex Coacervates Using a Volatile Salt Biomolecular condensates are liquid droplets formed by liquid–liquid phase separation and play a role in a variety of cellular processes. In the past decade, there has been a growing interest in their...

First paper of Systems Chemistry Lab is out! Check out how Lunan achieved with @guillemonreals.bsky.social time-controlled formation and ageing of coacervates by using a volatile salt 👇 Congrats to all authors!

Reactions of ribose relevant to the origin of metabolism apparently occur in aqueous microdroplets but not in bulk water. Why not? Computations suggest it's electric fields.

Thanks @thijsstuyver.bsky.social and @javialra97.bsky.social for the great collab!

We have a PhD position on reaction networks driven by aminoacyl phosphate esters funded from @ercresearch.bsky.social at @uni-freiburg.de.
Deadline for application is 20/03/25. More information can be found here: static1.squarespace.com/static/5fc39...

Looking for a stimulating conference on physical-organic chemistry ? We are organizing the 20th edition of ESOR from 9-12 September 2025 in Padova, Italy. Visit www.esor2025.com for info. Follow us on @esor2025.bsky.social to stay informed. #Chemsky. Reposts appreciated.

Job alert⚡Come and work with me and Joseph! We're looking for someone with experience in electrochemistry to work as a postdoc in Strasbourg. You'll be on a cool project in a young and dynamic team 🙂

What a coincidence: today I announced my retreat from twitter... Without regrets!

PhD projects available in a range of areas - something for everyone! Join us to do cool chemistry using the mechanical bond in catenanes and rotaxanes for real world applications in the shiny shiny new Molecular Sciences Building @uobchemistry.bsky.social 😊 Reposts appreciated! #chemsky

Hello #ChemSky! New year, new lab, and now also with a new website: systemschemistry-lab.chimie.unistra.fr

Check out for what @guillemonreals.bsky.social and myself are up to in the Laboratory of Systems Chemistry 😀

So glad this is out, congrats @alexblokhuis.bsky.social! Dimensionality analysis is going to be an unavoidable tool in mechanistic investigations of (presumably) complex chemical systems 🔥

Our first preprint was in collaboration with Maciej Piejko and @moranlabchem.bsky.social , and we investigated the mechanism of abiotic phosphorylation of ribose and the subsequent formation of ribonucleosides under the effect of an oriented external electric field ⚡
