    The Race to Build a Star on Earth, with Dr. Ahmed Diallo

    What if humanity could unlock an effectively limitless source of clean energy? In this episode of The Long Frontier, hosts Brannon Jones and Abe Murray explore the science, engineering, and commercial realities of nuclear fusion with Dr. Ahmed Diallo, Head of Enabling Technologies for Energy & Science at Princeton Plasma Physics Laboratory (PPPL).

    The Future of Biological Computing, with Dr. Hon Weng Chong

    What if the next generation of computers isn’t built with silicon — but grown from living neurons? In this episode of The Long Frontier, hosts Brannon Jones and Abe Murray explore one of the most unconventional frontiers in computing: biological intelligence. Joined by Dr. Hon Weng Chong, Founder & CEO of Cortical Labs, they unpack the emerging field of biological computers — systems that combine living neurons with silicon to create adaptive, energy-efficient computing platforms. From neurons learning to play Pong to the possibility of growing compute directly inside future data centers, this conversation explores whether biology may unlock capabilities traditional AI systems struggle to achieve. What You'll LearnWhy the human brain performs extraordinary computation using only ~20 watts of powerHow Cortical Labs taught lab-grown neurons to learn and play PongWhy biological systems may be dramatically more sample-efficient than modern AI modelsHow reinforcement learning in living neurons differs from traditional machine learningWhy biological computers may be especially useful for robotics and embodied AIThe biggest technical challenges ahead: memory, reproducibility, scaling, and ethicsWhy future data centers could potentially “grow their own compute”The overlap between biological computing and brain-computer interfaces like Neuralink Featured Guest: Dr. Hon Weng ChongDr. Hon Weng Chong is Founder & CEO of Cortical Labs, a Melbourne-based biotechnology company pioneering biological computing systems powered by living neurons. A trained medical doctor and software engineer, Chong previously co-founded CliniCloud, a medical technology startup backed by Tencent and Ping An Ventures. His work at Cortical Labs gained international attention after demonstrating that lab-grown neurons could learn to play Pong. The company has since introduced commercial biological computing platforms including the CL1. Notable Moments“If Neuralink is trying to put a chip inside a brain, we’re doing the opposite — we start with the chip and grow the brain on top of it.”The discussion explores whether biological systems can outperform traditional AI in real-world learning tasks because they adapt continuously instead of relying on massive pre-training datasets.Hon also explains why neurons may fundamentally optimize for reducing “surprise” — an idea inspired by neuroscientist Karl Friston’s Free Energy Principle.
