Interesting video from The Atlantic on reviving a coral reef in Florida.
David Vaughan works on the Florida Reef Tract, the third largest coral reef in the world and a vastly important ecosystem for sustaining underwater life. He and a team of scientists are working to combat the crisis in the world’s coral reefs—that is, that human beings have lost 25 to 40 percent of the world’s corals in recent decades due largely to seawater temperature rise and continued acidification of the ocean. Vaughan has developed a technique called “microfragmenting” that allows corals to grow more than 25 times faster than normal, which could rapidly restore the dwindling population of healthy coral reefs. The Atlantic went inside the Mote Tropical Research Laboratory in Summerland Key, Florida, where Vaughan is the executive director, to uncover how the process works and understand how much hope there is to reverse the damage caused by humans.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
