Self-propelled actin filaments: Novel structures driving spontaneous cell morphogenesis

Researchers reveal a previously unrecognized form of actin self-organization that may help explain how cells spontaneously generate shape and movement. Live-cell imaging and computational modeling show that these self-propelled treadmilling actin filaments (SpTAs) drive cellular protrusions through a process powered by treadmilling.

Big impacts from small changes in cell

Researchers at Göttingen and Warwick Universities studied the structure and mechanics of cytoskeletal networks composed of actin isoforms. The study found that gamma actin forms rigid networks near the cell apex, while beta actin preferentially forms parallel bundles with distinct organizational patterns.

How repeated spot microdischarges damage microdevices

Researchers found that repeated spot microdischarges in microelectronic devices cause a temperature increase, which reduces the electric field and leads to preferential breakdown at the previous discharge location. This study provides insights into the role of residual heat build-up and its impact on device stability.

Researchers gain new insight on wonder of cell division

Biologists have found a critical mechanism in cell division, promoting cytokinesis completion by down-regulating branched microfilaments. The discovery uses roundworms and provides insight into protein interactions and signaling mechanisms.
