- Reposted by Violeta CallejaI'm really happy to see this article being published! I find it very intriguing that the topology of genotype networks, which reflects the exploration of the antigenic space, can alone be enough to explain seasonality in epidemic trajectories.
- Reposted by Violeta Calleja🚨 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/

- Reposted by Violeta CallejaWhy do some cancers respond to immunotherapy while others don’t? A new paper by @guimaguade.bsky.social shows, using maths, that as tumors mutate, they face a trade-off: growing faster can also make them easier for the immune system to spot. @sandyanderson.bsky.social www.biorxiv.org/content/10.1...

- Reposted by Violeta CallejaEcology faces an accumulation of models but not an accumulation of confidence. Our new paper w/ Jonathan Levine www.nature.com/articles/s41... in @natecoevo.nature.com introduces a rigorous test rooted in queueing theory to falsify inadequate models and build confidence in useful ones.
- Reposted by Violeta CallejaOur new paper shows that bonobos and chimpanzees organize their relationships in human-like “circles of friends.” Also, bonobos spread their attention more evenly while chimps are more selective — and grow even more so with age, just like us.
