Lemma Journal Club, Ep #15! 🍦A soft matter physics episode!

Paper is: “Reconfigurable self-assembly through chiral control of interfacial tension” www.nature.com/articles/nat...

Kinesin-4 (cyan) mixed with Kinesin-1, with PEG and microtubules (red). I spent the rest of my PhD trying to understand Kinesin-4 on it's own in this sort of system, and we never came back to mixing them.

From @linnealemma.bsky.social , an active nematic liquid crystal. But the system doesn't have enough phosphoenol pyruvate to keep fueling ATP regeneration, so watch the motion stop and the liquid crystal lock in from right to left!

I can't believe we never published any of this stuff. It's so bittersweet everytime I go through old presentations and find it again.

We finally picked a Chicken paper for the Lemma Journal Club!🐔 "I demand that there is a picture of a chicken in every single one of these subfigures." 🐔 youtu.be/1wz49Hmaeck?...

Algal pyrenoids—condensates that mediate ~1/3 of Earth’s CO2 fixation—change size and number as cells divide. Our data suggest a simple control mechanism: a kinase that continuously ejects material from the condensate! ☀️🌍🔬💧 #Biophysics #Photosynthesis
