This is a picture of a wave crashing on the New Jersey shore. It glows because of dinoflagellates — little, single-celled plants, animals, and bacteria that float around on the water, moving about with the help of long, moveable protein strands called flagella. Some dinoflagellates are bioluminescent; that is, chemical reactions inside their bodies produce light. The result is glowing oceans. Or, as maker Caleb Kraft recently discovered, the dinoflagellates also make for a soft blue nightlight with really nifty special effects.
You can watch Kraft's nightlight project at YouTube. It's pretty simple to do at home. At it's most basic, all you need to do is purchase some bioluminescent dinoflagellates online, keep them alive in your home, and give them a good shaking occasionally to trigger the chemical reaction.

Sometimes, in the course of his work, University of Florida molecular geneticist Martin Cohn must travel with unusual items like a 3D-printed mouse penis. Similarly, University of Massachusetts biologist Diane Kelly totes around anatomical models like a mold of a dolphin vagina. They’re not alone in the odd science-related items they must fly with, from […]
Rod McCullom at Undark has a terrific overview of the perpetual “virtual lineup,” where half of all American adults “are enrolled in unregulated facial recognition networks used by state and local law enforcement agencies.”
It sure feels flat, right? (Life Noggin)
