"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.
Why we like itMost of the time, we see really stellar TV deals sell out as fast as they appeared. That's not the case for the 75-inch Hisense U7 Mini LED TV. We featured this "ultimate mid-premium" model from 2025 last week, but it's still down to just $899.99 at Amazon if you missed it. It's list price is actually near $2,000 (which you can see on the Best Buy website), which means this is an even bigger deal than Amazon is letting on. Standout features of the U7 include Mini LED backlighting with an AGLR-Antiglare low-reflection panel, up to 3,000 nits of brightness, and HDR10, HDR10+ Adaptive, HLG, Dolby Vision IQ and Dolby Atmos. Plus, it features an impressive 165Hz refresh rate, which makes it a top pick for gamers.

Then came the bigger leap. In the early 2000s, Gran headed south, determined to prove the model in the far more competitive U.S. market. In 2003, SpeedPro Imaging took root in Texas with three pioneer studios in Austin, San Antonio, and Plano. They were small, lean operations built around large‑format printing and fast turnaround.
