"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.

One reason the North Sea is emerging as a CCS hub, is its oil and gas legacy. After decades of production, the geology of potential storage sites is well explored, says Niels Schovsbo, a senior researcher at the Geological Survey of Greenland and Denmark (GEUS).
Nothing actually offers a couple of earbuds, as well as full-sized headphones, including the Nothing Headphone 1 and Nothing Headphone Pro. The Headphone (a) name indicates that these are an entirely new product line.
