Ella Al-Shamahi set out to disprove the theory of evolution. Now she’s one of its greatest advocates. In this deeply personal conversation, Ella tells Hakeem her story. She started university as an avid creationist missionary with the intention of disproving evolution, and then her world started to fall apart. This candid conversation covers what the journey from creationist to paleoanthropologist actually looked like, and the evidence that shifted her thinking. It is a path with personal costs and the impact of changing worldviews. It's a thoughtful reflection on science, identity, community and why empathy matters more than argument when deeply held beliefs meet new evidence.

She specializes in human evolution and has conducted fieldwork in some of the world's most dangerous and remote regions in search of fossil evidence of our earliest ancestors. She is a TED speaker and has appeared in numerous science documentaries, including hosting NOVA and BBC’s five-part series HUMAN, available on the PBS App and NOVA’s website.

Earthquakes can be more powerful than atomic bombs. Luckily, Harvard geophysicist John Shaw has ideas on how to beat them. What really causes earthquakes? How can cities and buildings be engineered to survive them? John and Hakeem trace the science of shaking ground from ancient myth to cutting-edge machine learning, and reveal just how much is still left to discover deep beneath the surface.

Dudley Professor of Structural and Economic Geology at Harvard University, where he also serves as Vice Provost for Research. A structural geologist and applied geophysicist, he studies the faults deep beneath our feet, with research spanning earthquake hazards, energy systems, and carbon storage.
We can cause earthquakes. Geophysicist John Shaw joins Hakeem to reveal how humans have been triggering earthquakes for decades, and in some cases, it’s on purpose. John explains how an experiment 50 years ago turned earthquakes on and off and clarifies all the confusion around the process of fracking. It's a surprising look at how understanding human-triggered quakes might be the key to predicting natural ones.

We can’t predict earthquakes, but we can beat them. Geophysicist breaks down what actually keeps people alive when the ground starts shaking. From flexible buildings to early warning systems, John walks Hakeem through what separates cities that survive major earthquakes from cities devastated by them, and why the difference often comes down to policy not physics.
Big earthquakes can change the Earth’s rotation. And Harvard geophysicist John Shaw says these giant events can teach us a lot. He traces our understanding from ancient myths to modern studies and unpacks what;s really going on beneath the surface. John reveals why a magnitude 7 earthquake releases 30 times the energy of a WWII-era atomic bomb, how the largest quakes make the Earth ring like a bell for days, and why the deadliest earthquake in history wasn't even the biggest one.
There is a near-limitless energy source to power our world, and it may be almost here. Dennis Whyte shares with Hakeem that we're closer than ever to bottling the power of the sun. He would know. He’s now the CEO of the United Kingdom’s Atomic Energy Authority and a nuclear scientist at MIT. What happens when we finally unlock nuclear fusion, the same energy source that powers the sun? What even is fusion? How does it work, and why are scientists now so close to building commercially viable fusion systems that could put power on the grid? From fusion fundamentals, to the future of energy, to interstellar space travel, Dennis and Hakeem deliver a big conversation on an innovation that could change everything.
