Thanks to all the speakers, poster presenters & participants, and to @giodal.bsky.social for co-organising!

Still a few days to register!! #BCNCollaboratorium #IQS #Mathsandbiology

Last few days to submit your abstract 📮

📢 Join us and @n-martin.bsky.social on June 17 at IQS Barcelona for a full day of mathematics, modelling and biology. Maths and Numbers in Biology: thematic sessions, poster presentations. Register by June 8: mathsbio.iqs.url.edu #BCNCOllaboratorium #SystemsBiology #ResearchEvent

🧮 Join us for "Maths and Numbers in Biology" - a one-day symposium on 17th June at IQS Barcelona. Co-organised with @giodal.bsky.social, to bring together mathematical and computational biology research from across BCN: mathsbio.iqs.url.edu

Out now in PLOS Computational Biology 🧬 We have an established theoretical framework for genotype–phenotype (GP) maps, describing their structural features and how those features shape evolution. But much of this assumes one discrete phenotype per genotype - which is often not true.

How do evolving populations navigate complex fitness landscapes? Find out more in our colleague @n-martin.bsky.social’s blackboard talk at the Kavli Institute for Theoretical Physics online.kitp.ucsb.edu/online/compl... #BCNCollaboratorium #fitnesslandscapes

Enjoying my sabbatical visit in Barcelona, discussing science with @n-martin.bsky.social:

Welcome to the New Trends in Non-equilibrium Dynamics #complexsys26 program at KITP! May 11 - July 16, 2026 buff.ly/WF8olMH

New research in #GENETICS from @msrivastava95.bsky.social, Ard Louis, and @n-martin.bsky.social focuses on fitness landscapes built from genotype–phenotype maps with a random phenotype-fitness map and makes analytic predictions about their topographical properties. 🔗 for the paper: buff.ly/VnQ796V

Thank you to Pau Formosa-Jordan for an excellent seminar on plant multicellular dynamics, from cellular patterning to developmental transitions. Thanks as well to Nora Martin for hosting this seminar.

Looking forward to @pauformosa.bsky.social's talk next week 🌱 - note that this month, our seminars will be held at the PRBB (Curie room).

🧵 New preprint: doi.org/10.64898/202... In 2023, Papkou et al. reported an empirical fitness landscape with a striking property: >500 local optima ("peaks"), spanning both high and low fitness. Despite this ruggedness, >75% of simulated adaptive walks reached the top ~14% of peaks.

Visites guiades, tallers, xerrades... activitats de tota mena i per a totes les edats ⏩ Tothom alerta que aviat obrim les portes a la ciutadania en una nova edició de l'#OpenPRBB❗️ 🗓️ 4/10, de 10 a 14h 👆 Us explicarem què fem, com ho fem i on ho fem ℹ️ https://tuit.cat/jfg0q

Congratulations to the graduates and thank you for the invitation!

Excited with two new preprints on evolution of molecular structure, in RNA (doi.org/10.1101/2025..., @n-martin.bsky.social) and proteins (doi.org/10.1101/2025...). Both RNA and protein structures are often conserved across evolution, but the underlying reasons are very different.

“The complexity of adaptive landscapes” @n-martin.bsky.social, @crg.eu #festamajordegracia #ESEB2025 satelite outreach activities by @lcatmon.bsky.social AUGUST 20th, #BCNevolutionDay

#festamajordegràcia is concluded for @lcatmon.bsky.social it's been 1 more bucket list ✅️ to bring #evolution to one of the most important festivities of #Barcelona Thanks #44Perill, @ajuntamentbcn.bsky.social #eseb2025 @sesbe-org.bsky.social and for the support and trust! Activities Summary 👇

🔬Yesterday at Festa Major de Gràcia, Nora Martin explained how maths and simulations help us understand biology through the lens of high-dimensional fitness landscapes. 😌We are very happy to see our research explained in this setting! 🎁Making science accessible to everyone is key.

In a session at 17h on Wed 20th, Nora Martin will discuss The complexity of adaptive landscapes at the Festa Major de Gràcia. You are welcome to attend! -Event info: lacienciaalteumon.cat/evolucio-gra... -Nora is a CRG Independent Fellow at the Collab: barcelonacollaboratorium.com/fellow/nora-...

Due to the stochasticity of biological processes, many realistic genotype-phenotype maps are non-deterministic (ND). ND maps from distinct computational models share features at a coarse-grained level. These shared features can be reproduced with a simple model: www.biorxiv.org/content/10.1...
