Big Brain News Ep. 39: Canned Salmon Time Travel, Whale-Head Termites, and a Moon with a Nickname!

Episode 39 (2026-04-03) Today’s stories (kid-friendly science): 1) Canned salmon as a “time capsule” • Researchers examined canned salmon collected across decades (research only) to look for tiny organisms seen under microscopes. • The patterns can help scientists understand connections in ocean food webs—who eats what, and how energy moves through an ecosystem. 2) A new termite species in the rainforest canopy • Scientists described a new termite found high in the forest “roof” (the canopy). • The termite’s head shape inspired a whale comparison—careful observation helps scientists identify and describe species. • In rainforests, termites can be important recyclers that help return nutrients to the soil. 3) The April full Moon nickname: “Pink Moon” • The “Pink Moon” usually isn’t pink; it’s a seasonal nickname. • Skywatching tip: look for darker patches (lunar maria) and notice how the Moon looks near trees or rooftops. Parent/Teacher Corner: • Gentle episode overall. • Brief mention of tiny ocean hitchhikers under a microscope; families can skip or soften that line if needed. Discussion questions: • What’s one clue from nature you’ve noticed recently (in the sky, a park, or even your food)? • If you could name a full Moon, what silly nickname would you pick and why?
