Centuries-Old Arctic Creatures Surviving on Fossils
What is the oldest animal on earth? Bow whales live up to 200 years. Greenland sharks can live more than 400 years. But how many of them eat fossils? Only the recently discovered centuries old sponges living on an underwater mountain range at the up near the North Pole. Here’s more from MOTHERBOARD:
The discovery of this stunning biological hotspot is a testament to the resilience of life in even the most inhospitable environments, like the dark and nutrient-poor slopes hidden under the Arctic sea ice. Given that human-driven climate change is warming this Northern region at least twice as fast as the rest of the planet, better knowledge of these surprisingly vibrant ecosystems “is essential for protecting and managing the unique diversity of these Arctic seas,” according to the study, which was published on Tuesday in Nature Communications.

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.
