A simple fold can completely change how a material behaves. By changing structure instead of material, origami can transform flimsy sheets into rigid, shape-shifting systems. And scientists are still discovering entirely new ways to fold. Hosted by Athena Brensberger @astroathens 💫 📰 Stay up to date on the latest science […]

The search for dark matter may be taking a surprising turn. Theoretical physicist Elba Alonso-Monsalve explains why the decades-long hunt for dark matter has led many physicists to a surprising candidate: primordial black holes. What are these mini black holes and how might they have formed? And could upcoming experiments […]

Wendy Suzuki hopes you have anxiety—good anxiety. She thinks that feeling you try to avoid could actually be your edge! Wendy joins Hakeem to explore how anxiety can be harnessed, rather than eliminated, and how it connects to two other powerful forces shaping your brain: exercise and human connection. What’s […]
