The Taliban government says they were "retaliatory operations" - a response after "Pakistani military elements carried out an incursion into Afghan territory, violated Afghan sovereignty, and caused the deaths of several civilians, including women and children".
"Tuning frictional behavior on the fly has been a long-standing engineering dream," said co-author Katia Bertoldi of Harvard University. "This new insight into how surface geometry governs slip pulses paves the way for tunable frictional metamaterials that can transition from low-friction to high-grip states on demand.” In addition, the dynamics revealed by these results are similar to those of tectonic faults and thus give scientists a new model for the mechanics of earthquakes, according to their new paper published in the journal Nature.
