"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.
American hockey player Brady Tkachuk said Thursday that he did not appreciate a doctored TikTok video shared by the White House that made it look like he was disparaging Canadians after winning Olympic gold, calling it fake and something he would never say.
