| תקציר: | DNA in living systems is constantly reshaped by mechanical forces, yet how mechanics alone can organize DNA at large scales remains unclear. In this talk we show a minimal active composite of microtubules, kinesin motors, and DNA in which active flows stretch and entangle DNA into a self-organized viscoelastic network. This mechanical feedback drives a nonequilibrium transition from disordered flow to synchronized, millimeter-scale oscillations. An active-gel model captures the emergence of oscillations without chemical signaling, revealing a physical route to autonomous, coordinated dynamics in active soft matter. |
