  • Résumé

  • First up this week, Staff Writer Paul Voosen joins host Sarah Crespi to discuss mapping clogs and flows in Earth’s middle layer—the mantle. They also talk about recent policy stories on NASA’s reactions to President Donald Trump’s administration’s executive orders. Next, the mantis shrimp is famous for its powerful club, a biological hammer it uses to crack open hard shells. The club applies immense force on impact, but how does it keep itself together blow after blow? Nicolas Alderete is an associate researcher at the National Institute of Standards and Technology, but at the time of the work he was a graduate researcher in theoretical and applied mechanics at Northwestern University. He joins the podcast to discuss the makeup of the mantis shrimp’s club and how it uses “phononics”—specialized microstructures that can reduce or change high-frequency vibrations—to reduce wear and tear when smashing and bashing.
