Five years ago, researchers at the University of California, Berkeley; Stanford; and Lewis and Clark College found the secret: 500,000 minute hairs cover the sole of each foot, and the tip of each hair splits into hundreds more. "It's this incredible synergy of the flexibility, angle and extensibility of the hairs that makes it possible.". Although the scientists have tested only minute amounts of the material, they estimate that if its properties hold up on a larger scale, a dime-size patch of it could support 2 to 22 pounds, depending on how densely the hairs were packed.

If we've learned anything from the COVID-19 pandemic, it's that we cannot wait for a crisis to respond. The numbers may not be exact, but they certainly paint a picture of repeated gains and losses. Now, scientists have zoomed in for an even closer look at those structures, called setae, and found that they are coated in an ultra-thin film of water-repelling lipid molecules only one nanometer, or billionths of a meter, thick. This climbing ability is due to tiny hairs, called setae, on the bottoms of their feet that can only be seen with a microscope. Coupled with that, smaller lizards are sometimes too curious so they may climb on your bed without even knowing what they are doing or looking for. Unit Operations of Chemical Engineering (Warren L.
