How did Earth get its magnetic field? And why does it move around? Our listeners have questions about one of Earth’s most mysterious forces. To find out, we go on an archeological expedition in the Middle East, with pioneering paleomagnetist Lisa Tauxe. Lisa has spent decades “hunting” the magnetic field through time, to understand what ancient artifacts can tell us about how the magnetic field has changed. Did you know, magnetic north doesn’t stay in one place – and sometimes it flips? If you feel yourself pulled into this mystery, hit play on this episode!

Why did T. Rex have such tiny arms? That’s what our listener Nora wants to know. We’re going to find out why the biggest, most powerful predator to ever walk the Earth did it with a teeny tiny set of arms.

Scientists have been coming up with answers for this question for decades — but science is never settled. Paleontologist Elizabeth Steell has walked into the debate with a stunning theory involving giant heads, evolutionary tradeoffs, and some serious math. Will it convince you? Listen and find out!
