  Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (7 Favorites)

  The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

  Video: Ingenious Video 3: This Sandwich Will Save Your Life in an Arc Flash Mark as Favorite (3 Favorites)

  It’s never fun when your clothes catch on fire. And while “stop, drop, and roll” may be a good idea sometimes, in more extreme cases, you need a better plan. Every day, industrial workers, firefighters, and soldiers risk fiery situations that might seem hard to imagine. In an arc flash event, for one, temperatures can jump to metal-melting levels in milliseconds. How can anyone possibly survive that? Well, take a tip from a club sandwich, because it’s all about the layers. The composite fabrics that protect life and limb in these situations rely on some incredible, multilayered chemistry, including the ability to quickly form a protective carbonaceous crust around the wearer.

  Video: Ingenious Video 2: What Birds Know About Color that You Don't Mark as Favorite (7 Favorites)

  We’ve been using pigments and dyes for thousands of years, but they’re not the whole story when it comes to making color. “Structural” color occurs when tiny nanostructures interact with light waves, amplifying certain colors and canceling others. From brilliant bird feathers to butterfly wings, mole hairs to octopus skin, structural color is everywhere in the natural world. Researchers have tried for years to harness this incredible natural phenomenon in a useful way. Because these colors are so small and complex, and therefore hard to copy, their efforts have met with little success. But novel research using a computer model based in repeated random sampling — a so-called “Monte Carlo” model — is showing promise. Using this approach, scientists have been able to mimic the gorgeous blue of the mountain bluebird in a thin film of reflective beads, leapfrogging millennia of evolution.
