"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.

When it comes to the president, chaos is often the strategy. For businesses like Smeaton’s the opposite is needed—stability. Wearing Morph suits might be fun and gain you 5 million views on YouTube. But a potential wipeout of your profits after the latest announcement from the White House is hardly a laughing matter.
