"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.

Tips on spotting if it's fake news or factApplying some critical thinking can help you tell if a piece of news is fake or genuine. As Leigh-Anne said: “Don’t take everything at face value because things can be twisted [and] manipulated, so it’s always really important to do your own research.”，详情可参考WPS官方版本下载
