At Michelangelo’s Medici Chapel, Stain-fighting Bacteria Work Miracles #ArtTuesday
A secret project using microbes to clean up centuries of grime. From Hyperallergic:
Enter SH7, a bacteria that feasts on glue, oil…and presumably the ancient remains of assassinated royals, leaving the decorative surfaces of the chapel and its statuary gleaming and pristine as they’ve never been within the modern era. The brain trust that analyzed the surface conditions of the tomb included Italy’s National Research Council, which used infrared spectroscopy that revealed calcite, silicate and organic remnants on the sculptures, and Anna Rosa Sprocati, a biologist at the Italian National Agency for New Technologies, who surveyed and tested bacteria from a collection of almost 1,000 strains to find one that would eat the offending phosphates and proteins, but leave the Carrara marble untouched.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
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.
