Meet the ultimate gatekeeper of the nucleus. This molecular machine determines what compounds are welcome inside and which shall not pass. The mechanism behind its selectivity remains a mystery. www.quantamagazine.org/disorder-dri...

In 1874, Georg Cantor published one of the most important papers in math’s 4,000-year history. The ideas in it were stolen. 🧵
This Thursday I'll be at @museuciencies.cat discussing chaos theory, time and its implications with @evamirandag.bsky.social and @ricardsole.bsky.social. Looking forward to it!

Podem predir el futur mitjançant les matemàtiques? Què ens diu la teoria del caos? Quins són els límits de la nostra capacitat de predir la complexitat? Parlarem amb Doyne Farmer, un dels pares de la teoria, i amb la matemàtica Eva Miranda @evamirandag.bsky.social

De curiositat contumaç, Ricard Solé (Barcelona, 1962) engolia tots els llibres de segona mà que arribaven a la biblioteca familiar. Aquelles lectures esperonaven encara ...
Our paper w/ @maguilera.net & Sosuke Ito is out in PRL. We combine ideas from stochastic thermodynamics & nonequilibrium Maximum Entropy to quantify forces + dissipation in high-dimensional nonequilibrium systems, including spin glasses and neural data

A four panel comic, from left to right: 1960s LIFE IS BASED ON DNA, WHICH USES RNA TO MAKE PROTEINS THAT DO STUFF. 1980s ALSO, THE RNA DOES SOME STUFF ITSELF, WHICH IS WEIRD. 2000s THERE ARE 50 MANY KINDS OF RNA. IT'S DOING SO MUCH STUFF! 2020s LIFE IS A SEETHING MASS OF RNA THAT SOMETIMES USES DNA TO TAKE NOTES. WHAT DO THE PROTEINS DO? ERRANDS FOR RNA.
It’s an RNA world. RNA is posited to be the first genetic material, arising 4 billion years ago. It can store information and act as an enzyme. Eventually, it duplicated its information into a more stable form, DNA.

Excited to share a new PhD thesis from my student and soon Dr @vmaull.bsky.social on synthetic ecosystems, preventing tipping points, and a new concept: emergent bioengineering. Very proud of this achievement, and thankful to @sfiscience.bsky.social, where many of these ideas came to life.

I like this paper, and not just for the obvious reason. A great summary of where we stand in thinking about types of mind. Nice also to see this made explicit: "All living systems share a fundamental property: agency."

4 am, els operaris segueixen de cháchara i ara a crits pel carrer. Moltes d'aquestes edificis son històrics i no tenen bones finestres (ni se'ls poden posar). No podem cancel·lar els sorolls. Una altra nit, moltes gràcies @ajuntamentbcn.bsky.social
Veig que els operaris es posen de cháchara a la cantonada del meu carrer (Argenteria), fent maniobres amb els camions, que xiulan omplint tot el carrer cada vegada que van marcha enrere... I així cada día, cada mitja hora, a aquestes hores del matí. No penseu en els veins o ké?
