Changes in membrane curvature influence how migrating cells navigate their environment. Experiments and modelling reveal that dynamic reorganization of the actin cytoskeleton in response to these changes provides cells with a sensing mechanism.
While topological states are often characterized by their global properties related to the topological invariants, the introduced real-space topological markers provide new insights to these states.
A major challenge for achieving useful thermonuclear fusion regimes is heating plasma to reactive temperature conditions. It is demonstrated experimentally how energetic ions, generated via neutral beam injection, can be exploited for this process.
