"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.

You could say that Brand has also lived big and long. He is now 87 years old, in the final chapters of an eventful and adventurous life that has crossed paths with some of the most consequential events and figures of his era. He has been a writer, an editor, a publisher, a soldier, a photojournalist, an LSD evangelist, an events organiser, a future-planning consultant, even a government adviser (to the California governor Jerry Brown in the late 70s). “There was a time when people asked me, ‘What do you do?’ I said, ‘I find things and I found things,’” says Brand, as in he is a founder. He is speaking from a library where he likes to work in Petaluma, California, not far from his houseboat in Sausalito. “I’m always searching for good stuff to recommend, and good people.”
