I absolutely loved Chris Barton's book, The Day-Glo Brothers, The True Story of Bob and Joe Switzer's Bright Ideas and Brand-New Colors. It's a children's book about the two brothers who invented fluorescent paint and Day-Glo paint. Joe Switzer wanted to be a magician when he was younger and he started fooling around with a black light that he and his brother Bob learned to make from a 1930s issue of Popular Science (I'm guessing it was this PopSci article from 1932).
They shined the light on the chemicals lining the shelves of their father's pharmacy and noticed that some of them glowed vibrantly. They started buying and mixing chemicals and eventually developed a number of different kinds paints that gave fluoresced under black light. Later, after much experimentation, the stumbled on paint that fluoresced under white light, which they dubbed "Day-Glo." The discovery made them very rich.
The book is illustrated by Tony Persiani, and it makes good use of Day-Glo ink, natch.
The world needs more fun history books like this!

As part of research on how to make better prosthetic legs, Vanderbilt University engineers put people on a treadmill and made them stumble. Over and over. By better understanding peoples’ stumble reflex, they hope to improve the computer-controlled stumble response in prosthetics. But to learn how people catch themselves, they had to trip them first.

Snail slime — called an epiphragm — is an incredibly strong yet reversible adhesive. Now, University of Pennsylvania scientists have developed a new kind of glue that employs the same mechanism as the epiphragm. The new material dries like superglue but once wet, it loses its adhesion. For years, scientists have explored adhesions inspired by […]

Even if you feel like AirPods are worth the price tag, you’ve got to admit there’s a certain anxiety that comes with using them. What if I lose them? What if they get wet in the rain? Or drenched in sweat? Or fall into the drink you dropped them into? Shiny tech is great, but […]
