"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.
Williamson earned his first screenplay credit in 1996 for Scream, swiftly defining a brand of horror where teens weren't stupid victims, but snarky, smart, and still susceptible to homicide. He'd go on to pen Scream 2 and 4. For Scream 7, he teamed up on the screenplay with James Vanderbilt and Guy Busick, who penned 5 and VI. And Williamson also takes the helm of this one.
