For anyone interested in stochastic dynamics, nonequilibrium/critical phenomena, Langevin equations, etc, I *strongly* recommend these new lectures (40x 40 min) by Erwin Frey (LMU Munich). Outstanding.

New preprint! We show how mesoscopic nonequilibrium fluctuations in active gels emerge from the breaking of detailed balance at the molecular scale. Warning: Long technical paper ahead! Enjoy! @mpipks.bsky.social @ub.edu @ubics.bsky.social @icreacommunity.bsky.social

Could the logic of life be shaped by the architecture of biological circuitry? In this paper, @manlius.bsky.social shows how genetic, metabolic, and social networks can govern slow evolutionary dynamics in a unified nonequilibrium framework. iopscience.iop.org/article/10.1...

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

Looks like an amazing summer school on nonequilibrium thermodynamics, from Christian Maes and Wojciech De Roeck
Leuven school: Basics of nonequilibrium statistical mechanics

Leuven school: Basics of nonequilibrium statistical mechanics
The school will give an introduction to basic concepts, models and techniques in the study of classical and quantum nonequilibrium statistical mechanics. Subjects range from thermalization issues to response and fluctuations in steady driven or active behavior. Intended audience are PhD students and postdocs with basic knowledge (Master level and beyond) of theoretical and mathematical physics. One day will be reserved for talks of the participants, plus feedback and discussion.

Living cells are nonequilibrium systems, constantly spending energy in seemingly one-way processes like transcribing DNA into RNA, to keep life going.

In a new paper, SFI's James Holehouse develops tools to study that irreversibility across thousands of genes, revealing interesting patterns.
Measuring irreversibility in gene transcription
Living cells are fundamentally nonequilibrium systems, meaning they constantly spend energy through seemingly one-way, irreversible processes, such as transcribing DNA into RNA, to keep life going. Bu...

How do we approach the complexity of life as a nonequilibrium system? Using physics and, in particular, landscape and flux theory, many systems, from cells to ecology and cancer, can be adequately represented and modelled. Check this paper in Reviews of Modern Physics

How do ecological communities respond to pulse perturbations (e.g. storms, wildfires)? We have a solid theory for stable fixed points, but what about cycles, transients, or chaos? In this preprint, we introduce a unified framework for these nonequilibrium cases. 1/7

Many condensates can be described as active soft materials that generate molecular fluxes. Here we develop a new #nonequilibrium approach (TRACE) to study molecular transport through condensates! Work led by Yashraj Wani!!

Very excited to share some life updates: in summer 2026 I will be starting as an Assistant Professor of Physics at University of Toronto! My group will study a range of problems in biophysics using nonequilibrium statistical mechanics—cellular signaling and adaptation, gene regulation, etc.

First preprint of the @pollyfordyce.bsky.social and @dunnlab.bsky.social collaboration! We used high-throughput microfluidics for sequence-strength mapping at the single-molecule level. Our new tech allowed us to discover a fundamental nonequilibrium property of multivalent systems. 1/13
