HMN 2025: How cell cytoskeleton mimics important phenomena seen in earthquakes and metals

Prof. Michael Murrell’s group (lead creator Zachary Gao Sun, graduate scholar in physics) in collaboration with Prof. Garegin Papoian’s group from the University of Maryland at College Park has discovered important phenomena (self-organized criticality) which might be harking back to the earthquakes and avalanches contained in the cell cytoskeleton by way of self-organization of purified protein elements.

In a groundbreaking discovery, researchers have discovered that the cell’s cytoskeleton—the mechanical equipment of the cell—behaves very similar to Earth’s crust, continually regulating the way it dissipates power and transmits info. This self-regulating habits allows cells to hold out advanced processes corresponding to migration and division with outstanding precision.

Even extra putting, the review attracts parallels between the habits of microscopic mobile constructions and large celestial our bodies, suggesting that the rules of criticality—where techniques naturally tune themselves to the brink of transformation—could also be common throughout vastly totally different scales of nature.

The outcomes additionally recommend a metal-to-insulator-like transition in info and power propagation may be tuned through autofeedback of geometry and energetic stress contained in the cytoskeleton, harking back to a phenomenon known as Anderson localization, generally seen in numerous condensed matter physics fields.

This additional signifies that the cell, as a residing equipment, makes use of energetic and mechanical rules generally seen in non-living techniques to course of info by way of self-tuning. The work is published within the journal Nature Physics.

“Whether the cell as equipment is being poised at a important state, and additional, how, have been the central matters for some biophysicists prior to now 20 years. Here, we now have noticed phenomena in a well-controlled experimental setting, and proposed the mechanism. Isn’t it wonderful to see similarities throughout scale objects underneath the microscope to the telescope?” Sun commented.

Sun and colleagues have found that cells might regulate info and power movement utilizing a mechanism strikingly much like a well known physics phenomenon known as Anderson localization—a course of sometimes noticed in non-living techniques like disordered metals and insulators. The analysis exhibits that the cytoskeleton, the cell’s inside scaffolding, can bear a metal-to-insulator–like transition in the way it transmits indicators and power.

This transition seems to be finely tuned by the cell itself by way of suggestions between its geometry and inside stress. The findings recommend that cells, like finely engineered machines, harness bodily legal guidelines from condensed matter to adapt and course of info—blurring the road between the residing and the inanimate.

This work motivates scientists in several disciplines to surprise if a scale-free common legal guidelines of criticality actually exists, and every cell is its personal “universe.”
