Pour some tau protein on a #microtubule, and the microtubule will contract. I still remember the first day we saw it happening in the #optical_tweezers. And I am happy I could contribute a little to this fascinating story. biorxiv.org/content/10.1101/…

You want to measure the active mechanics inside your favorite cell? Use our Mean Back Relaxation (MBR) that quantifies the non-equilibrium properties in active systems by simply recording the passive fluctuations and exploiting Onsager's ideas! biorxiv.org/content/10.1101/…
