In de Bolle's view, the Trump administration has an "imperialist vision" of Latin America that leads it to see the region's resources as its property. For her, private oil firms' aversion to Venezuela is a welcome barrier to that kind of resource grab.
"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.
