"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.

A strange piece of software has recently landed on the PC gaming store Steam. And “software” feels like the cleanest way to describe it. Existing somewhere between a full-blown life sim, a science project and a kind of haunted fish tank, Anlife: Motion-learning Life Evolution probably would have disappeared without making much impact if it wasn’t for one unusual factor. Several years ago some of its creators were absolutely roasted on camera by one of the genuine legends of Japanese animation.
