"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.

With its climate change angle and unlikely friendships, Arco recalls two of 2024's animated standouts: Flow and The Wild Robot. But it also forges an identity of its own thanks to its stunning 2D animation, which plays like a combination of the styles of Jean Giraud (aka Mœbius) and the films of Studio Ghibli. As I wrote in my review, "In a mainstream animation landscape dominated by 3D-animated films, Arco's visuals are a testament to the enduring power of 2D work, as well as French filmmakers' commitment to the medium. If you love animation, run, don't walk — or better yet, fly by rainbow — to catch it."* — B.E.
