The ordered state moves faster while consuming less power, as dissipation shifts from internal losses toward interactions with the environment. We then harness this transferred power to perform mechanical work with an active engine.

What could you learn about a collective system if you could resolve all of its energetic pathways? We track energy flow as active spheres transition from disordered motion to collective order. And the energetic state changes just as their motion. arxiv.org/abs/2609.31059

What if you got to work with some of your best friends on a science project? I can't publish how fun this was, but I can show you the data (🧵)! Last week, we posted our second neutrophil swarming paper to bioRxiv and I wanted to post my favorite videos here~ www.biorxiv.org/content/10.6...

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Could you elaborate on one of them? A realistic pathway that leads to such a system. While I wish for such a system to be the status quo, I fail to imagine a pathway that doesn't rely on: if in a wrong system we all do the right thing will transform the system. Has this ever worked?

Michael Riedl @mriedl.bsky.social · 07/03/2025

The belief that discoveries stem from and can be guided by lone geniuses, is at the core of this issue. Peer review and publishing follow the same pattern, where a few decide over the success of others, turning it into a lottery. What puzzles me is how do change this system from this point onward?

In fun news, a video of mine won the UCLA Broad Stem Cell Research Center's Imaging Competition! You can see a muscle cell (a myoblast) fusing into a moving myotube. These myotubes mature to become our muscle fibers. They are beautiful cells! 🤩 www.youtube.com/watch?v=g6xK...

Entropy is one of those formulas that many of us learn, swallow whole, and even use regularly without really understanding. (E.g., where does that “log” come from? Are there other possible formulas?) Yet there's an intuitive & almost inevitable way to arrive at this expression.

Mix two motors of opposite polarity with microtubules and they will partition space ! Microtubules will get organized in polar and active barriers, sorting the two motors in separated domains, leading to the emergence of a new type of patterns. #morphogenesis doi.org/10.1073/pnas... (1/n)

The cell contacts its chloroplast area by up to 40%! Where does all the material go? Smart design! Chlorophyll absorbs a lot - what is crucial is not its volume but is a high 2d-projected area for example a network. Fast contractions are driven via buckling of the network strands into the voids.

And when put together this allows us to recreate a phase diagram that neatly recovers the transition between solid liquid and gas phases. We are currently very excited about this work that is currently under review. Give it a read! arxiv.org/abs/2409.16734 (6/6)

Decreasing the number of balls in the system opens up different states. (5/6)

Michael Riedl @mriedl.bsky.social · 18/11/2024

Allowing us to show the phase transitions and calculate entropy as well as a temperature for the system. This allows us to identify unstable configurations that appear only for a short time. (4/6)

Michael Riedl @mriedl.bsky.social · 18/11/2024

So we try to assess the entropy of the states and came up with a neat definition taking into account the degrees of freedom utilized by the system. We evaluate those based on the tracks of translation and rotation in all spheres independently. (3/6)

Michael Riedl @mriedl.bsky.social · 18/11/2024

It is not as easy as it should be, we thought the same. However, the system undergoes phase transitions and during those the arrow of time becomes evident again. (2/6)

Michael Riedl @mriedl.bsky.social · 18/11/2024

We have an inherent intuition for the progression of time. In entropy producing systems the arrow of time should appear clear and a reversed movie feels thereby wrong. Look at these macroscopic active spheres and try to figure out whether the movie has been reversed.(1/6) arxiv.org/abs/2409.16734
