Interstellar Visitor 3I/Atlas, Human Longevity Plateau, New No-Sort Plastic & Analog AI

Hosted by Lester Nare and Krishna Choudhary, Episode 7 of From First Principles covers four stories at the frontier of science and technology. This week, we dive into new telescope data on the interstellar visitor 3I/Atlas, explore a major longevity study that suggests life expectancy may have plateaued, unpack a breakthrough nickel catalyst that could enable no-sort plastic recycling, and look at Microsoft’s analog AI computer — a potential game-changer for energy efficiency and medical applications.
