Great images. Thank you!

For example, you start thinking about getting a blue Honda Civic. Suddenly, you see them everywhere,in traffic, parking lots, and even ads. It’s not a car invasion,it’s Baader Meinhof. Your brain just tuned in.

Ever learn a new word or heard about something for the first time, then suddenly saw it everywhere? That’s the Baader Meinhof phenomenon. Your brain is just noticing it more, not that it’s happening more. #whatilearnedtoday

Octopuses have 3 hearts. Two pump blood to the gills, one to the body, and that last one stops beating when they swim. Swimming is so tiring. They prefer crawling. Oh, and their blood? It’s blue. #OceanFacts #WhatILearnedToday

Slime Molds help Nature by eating dead stuff, they clean up forests, and recycle nutrients.

Slime molds are tiny living things that can look like bright yellow or orange goo. They’re not molds like the stuff on old bread—they’re unique organisms called protists. They live in damp, shady places like forests, under logs, or in wet soil. #WhatILearnedToday #SlimeMold
