"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.

This decision seems to be one of the more hotly-contested among ergo enthusiasts. A conventional keyboard has staggered keys, with each row slightly offset to the rows above and below it — so the A key is about halfway between the Q and W above it. This is a holdover from vintage mechanical typewriters, in which each press activated a hammer that smashed ink onto paper in the shape of a letter. To fit the hammers as close together as possible, while still allowing for finger pads, the keys were staggered.
