I was at the IZS in Zurich last week, a spectacular conference in a beautiful location. I used my invited paper as an opportunity to explain what biological information theory is, and why I think it is important [PDF link]: www.research-collection.ethz.ch/server/api/c...
Great post on rationalism versus empiricism in the history of optimal control.
In 1874, Georg Cantor published one of the most important papers in math’s 4,000-year history. The ideas in it were stolen. 🧵
Fascinating paper — molecular error correction might not incur an accuracy/speed tradeoff. In fact, it may be favored by evolution simply due to increased speed

Which of these shapes looks like the sound "bouba", and which looks like the sound "kiki"?
People of all cultures agree on this, and now it's been found that baby chicks do too:

It's called the bouba/kiki effect, and I think it follows from physics!

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

Can we engineer cognition in aneural systems? What are the challenges and implications? Can synthetic biology be used to interrogate basal cognition? Our new paper with @jordiplam.bsky.social explores these questions using models of minimal gene circuits. Available here pubs.acs.org/doi/pdf/10.1...
"In other words, European taxpayers will have spent more on the funding process than on the funding itself, and the scientific ecosystem has been drained"
The situation is rapidly becoming unsustainable: the current research funding scheme does not work.

A remarkable preprint that shows emergence of active protocells from simple starting conditions

Yes, its possible to have local maxima of entropy. Supercooled water is one example, as are other phase transitions that require a "nucleation" event. en.wikipedia.org/wiki/Nucleat...

New paper in PRL on the relationship between thermodynamic driving and eigenvalues in Markovian master equations. We prove a weaker version of a beautiful conjecture proposed by Uhl and Seifert. Led by Guo-Hua Xu, with Jean-Charles Delvenne and Sosuke Ito

Cooperation is a universal feature of complex systems, from the origins of life and microbiomes to societies. What universal patterns can be found in these systems? Here's our new @pnas.org paper. @jordipinero.bsky.social @artemyte.bsky.social @sfiscience.bsky.social www.pnas.org/doi/epdf/10....
The characterization of life as a thermodynamic phenomenon out of equilibrium is usually attributed to Schrödinger.
What if I told you that he wasn't the first (not even the second😶🌫️) to reach that famous and influential conclusion?/1

Here is our new paper that we're really excited about. What makes a cell different from a rock? The answer we argue is the USE of information. But information carries meaning and that changes everything if we want to understand the "physics of life".

Proud of this preprint with my friends Jonathan Bauermann and @artemyte.bsky.social, about chemical oscillators & phase separation! Main findings:
1. Phase separation controls frequency and amplitude of oscillations
2. If reactions are fast, spirals of droplets emerge!
