Maxwell’s demon might lurk in enzyme behaviour The controversial process of enhanced enzyme diffusion could enable living systems to resist local equilibrium

Maxwell’s demon appeared to undermine the Second Law of thermodynamics by moving a system out of equilibrium. While there are flaws in that reasoning, enzymes may similarly help living systems to reach non-equilibrium conditions.

Always loved this album!

Enhanced Diffusion of Single, Lipid-Tethered Enzymes Recent experimental evidence has shown that enzymes that catalyze exergonic reactions are able to diffuse faster during catalysis, a process called “enhanced diffusion”. If true, enzyme propulsion cou...

JACS Front Cover Vol 147/Issue 52 Week Commencing 29 Dec 2026

‘Droplets as Cell Models: Chemical Gradient-Induced Directional Filopodia Formation', has made it on the front cover of this week's #JACS!

Explore the research behind the art: buff.ly/s30uUR7

https://pubs.acs.org/toc/jacsat/147/52: Droplets hunting for “chemical treasures”: oil-in-water droplets reshape in response to chemical gradients (from the glowing treasure chest), recapitulating how living cells detect and grow toward or away from environmental cues. By understanding the forces driving this behavior, the authors aim to build synthetic versions of cellular life and gain deeper insight into matter-to-life transitions.

🎉🎉The art I designed is now featured on the Front Cover of @jacs.acspublications.org!🎉🎉
Grateful to my mentor @ayusmansen.bsky.social for encouraging creative ways to illustrate our science.

@leecronin.bsky.social Are these droplets alive?

Very cool! Suggests the possibility of intra-organelle navigation using pH gradients.

Droplets as Cell Models: Chemical Gradient-Induced Directional Filopodia Formation Cells are complex chemical systems capable of sensing and responding to environmental cues by dynamically reshaping themselves, e.g., by forming arm-like protrusions such as filopodia. Recapitulating cellular behavior in artificial systems is a long-standing goal in understanding the matter-to-life transition and designing responsive soft materials. Here, we use oil-in-water emulsions that mimic cellular environmental sensing and form directional arm-like filopodia in response to external chemical cues. Our work analyzes the step-by-step process involved in the formation of artificial filopodia, and we engineer ways to direct filopodia growth through different chemical gradients. The process is driven by asymmetric surfactant partitioning across the oil–water interface, followed by ordering at the interface to form lamellar structures, which are projected out as filopodia. We observe filopodia growing away from the source of kosmotropic anions and toward the source of chaotropic anions from the Hofmeister series. Significantly, these systems also respond to amino acid gradients, similar to cells: tryptophan gradients favor growth toward the source, while lysine and arginine gradients cause growth away from the amino acid source. Our findings open new avenues for fabricating life-like materials that sense and grow in response to external signals.

As with Shakespeare, I always found myself coming out of a Stoppard play feeling more intelligent than when I went in.

Biological organisms exhibit purposeful behavior that allows them to survive and persist. They can also be described as material patterns maintained by flows of energy and information. When and how do the concepts of agency and purpose emerge as meaningful descriptors of certain material systems?

@philipcball.bsky.social @andrewbissette.bsky.social Is replication a strict requirement? What about a system that responds to the environment in ways that furthers its persistence. Does it not have "agency"? Is it alive?

U.S. Congress considers sweeping ban on Chinese collaborations Researchers speak out against proposal that would bar funding for U.S. scientists working with Chinese partners or training Chinese students

“The prohibited activities would include joint research, co-authorship on papers, and advising a foreign graduate student or postdoctoral fellow. The language is retroactive, meaning any interactions during the previous 5 years could make a scientist ineligible for future federal funding.”

RIP Jim Watson. You inspired many of us to pursue a life in research. I wish you had made it easier for us to celebrate your legacy.

Congratulations, Job!!

Congratulations, @sanjanakmani.bsky.social! Nice work!
