Already 115 million years ago, tropical flowering plants were apparently very diverse and showed all typical characteristics. This is the conclusion of an international team of researchers led by Clément Coiffard, Museum für Naturkunde Berlin. The team reported in the renowned journal Nature Plants on the oldest completely preserved lily, Cratolirion bognerianum, which was discovered at a site in present-day Brazil. With the help of 3D computer tomography at the Helmholtz-Zentrum Berlin, details on the back of the fossilised plant could also be analysed. The results raise new questions about the role of the tropics in the development of past and present ecosystems.
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.
