The structures have names such as “the corncob”, “the cauliflower” and “the hedgehog”. One of the more interesting findings is that the oxygen-loving bacteria live on the edges while the bacteria that live without oxygen tend to live in-between.
Mapping the bacteria required creating a set of tags to identify each of them. Since there may be hundreds of bacterial species living on our teeth, the researchers needed to figure out which species were most abundant.
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.
