Some analyse chemical bonds to compare them against genuine honey samples. Others analyse isotopes to determine where a product likely originated.
That was the gap. confusable-vision is the tool I built to close it: render every confusable pair, measure the pixels, and put a number on what “visually confusable” actually means.

"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.
