You might expect active matter to become more active if you fire it up. Here the opposite happens! - Prashanth Ramesh has frozen his microswimmers by heating and will tell you all about it here: doi.org/10.1002/adma.2024168…

Thrilled to see this paper published @PNASNews! Check it out at doi.org/10.1073/pnas.2503983…. In it, we describe how swimming bacterial suspensions spontaneously organize themselves in unexpected ways when oxygen starts running out. Summary in the tweetorial below ⬇️

Spatial self-organization of confined bacterial suspensions | PNAS

Lab studies of bacteria usually focus on cells in spatially extended, nutrient-replete settings, such as in liquid cultures and on agar surfaces. B...

Excited to release our latest work, led by @BabakVH: doi.org/10.1101/2025.02.20.6… Here, we describe how confined bacterial suspensions self-organize into structured domains of different motilities, in response to oxygen limitations🦠🍥 Tweetorial follows! [1/8]

Thanks for the heads-up! advanced.onlinelibrary.wiley… (weird, it worked for me...)

Frozen by Heating: Temperature Controlled Dynamic States in Droplet Microswimmers

In the design of smart materials based on active agents or microswimmers, the gaits or motile states of the agents are to be controlled, preferably by external parameters that do not require modify...

Imagine being able to manipulate the movement of #microswimmers. By using electric fields and pressure-driven flow, scientists now developed a navigation system for microswimmers with potential for micro-robotic and biotechnological applications. ds.mpg.de/4071871/241029_mic…

Huge congrats to @AntoineDeblais and Daniel Bonn at @IoP_UvA on the IgNobel. science.org/doi/10.1126/scia… Let's have a drink ... or two ... or three ... to celebrate!

Chromatographic separation of active polymer–like worm mixtures by contour length and activity

A unique way to sort mixtures of active polymers on the basis of their length and activity is demonstrated.

Our article on Mathematical Billiard with Spatial Memory is now out @PhysRevLett journals.aps.org/prl/abstrac… Here is a short thread 🧵on what we have done. Might be of your interest if you like active matter, memory, topology, chaos, etc. or simply mathematical games 👾

I think there should be a group administrator appreciation day. Especially if they're gardening wizards to boot. (well, we all know that along with techies and lab managers they are the only truly indispensable people around) 💚💚💚
