Science teacher & HHMI BioInteractive Ambassador Samuel Washington Jr. draws students in with more than textbooks. “At first, kids love science—bugs, their bodies, the outdoors—but if you don’t tap into that natural curiosity, they lose it." Via @neatoday.bsky.social bit.ly/4pD1w9W 📸Shea Kastriner

What is science? And why do we need it? In this episode of Crash Course Scientific Thinking with host @hankgreen.bsky.social, we explore how cognitive bias shapes the way we think about the world, and how scientific thinking can help us overcome it. youtu.be/d2r7Bk1NlgU

Hank Green will be lending his passion for science to the Crash Course screen as host of Crash Course Scientific Thinking. @hankgreen.bsky.social will be joined by special correspondent Sage "The Bad Naturalist" to help us understand foundational principles of scientific thought youtu.be/Y45KrixWRNg

Some exciting news from our friends at @thecrashcourse.bsky.social! And don't worry — we'll have classroom resources to accompany this series sometime this year. 💚💚💚

The world’s “most dangerous animal” just got easier to study 🦟 HHMI’s @leslievosshall.bsky.social & #VosshallLab at @rockefeller.edu have built the 1st cellular atlas of Aedes aegypti, mapping everything from legs to antennae. Available now to all researchers, & the public: bit.ly/4oO4MzB

The first detailed look at how mosquitoes mate from @leslievosshall.bsky.social's lab reverses the assumption that male mosquitoes control the process, finding that a subtle female behavior dictates whether mating will take place or not. @currentbiology.bsky.social More here: https://bit.ly/4huwEpL
