A coloring book starring prehistoric tooth extractions, plague rats, and ancient colon contents could be just the right stress reliever for this holiday season. Coloring books are supposed to be soothing — but this one is also scientifically accurate.
Called “Adventures in Archaeological Science,” the 12-page book delves into what microbial archaeologist Christina Warinner calls the “archaeology of the invisible”. Warinner, the book’s editor, investigates how tiny microbes like bacteria have shaped human health over time. She studies the gunk still caught between the teeth left in human skulls, ancient poop, and the leftover streaks of food still coating prehistoric pots. So you’ll find a gap-toothed skull and plenty of bacteria, like the ones that cause plague and leprosy.
The coloring book is the product of a two-week workshop on digital illustration that Warinner and her colleague Jessica Hendy taught at the Max Planck Institute for the Science of Human History. Each student in the course designed and illustrated a page, and Warinner and Hendy added the finishing touches. Right now, the book is available for free as a PDF in English, German, and Spanish. But more translations are on their way, including Chinese, Nahuatl, Italian, and Mongolian.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
