This morning’s Nobel Prize in Economics recognizes two researchers who helped explain something counterintuitive: a central bank can influence the economy simply by changing what people believe will happen next. We explore how inflation expectations, sticky prices, and individual spending decisions became the foundation of modern monetary policy—and why these ideas matter as AI investment reshapes the global economy. Plus: Amazon considers a $7 billion acquisition that could weaken Nvidia’s grip on AI computing, and scientists discover a surprising immune-cell signature associated with healthy aging.

This morning’s Nobel Prize in Medicine went to the scientists who figured out how to control individual neurons with flashes of light. We go inside optogenetics: how a protein from pond algae became one of neuroscience’s most powerful experimental tools, why it changed the difference between correlation and causation in brain research, and why turning the technique into a human therapy is much harder than using it in a mouse. Then: Schneider Electric puts $22.6 billion behind the idea that industrial AI needs structured physical-world data, a German robotics startup hits a $1 billion valuation, and Deutsche Telekom gives us a useful test of whether enterprise AI is finally turning into measurable economics.

A Nvidia-backed startup is preparing a powerful open-weight model aimed at breaking China’s lead in open AI—and giving companies an alternative to renting intelligence from OpenAI, Anthropic, and Google. We go inside how open-weight models actually work, why proprietary company data can sometimes matter more than having the smartest base model, and why Nvidia has a powerful reason to make models cheaper and more interchangeable. Plus: why Schneider Electric may spend $20 billion moving from data-center hardware into industrial software, and what a new study can—and cannot—tell us about food and sleep.

The evolution of SpaceX from a struggling launch provider to a dominant global aerospace and technology power. A 2015 launch failure caused by a structural design error led to rigorous independent reviews and subsequent engineering refinements. This commitment to reliability paved the way for record-breaking rocket reusability, exemplified by a single booster completing dozens of successful missions.

More recent developments highlight the company’s massive financial expansion through a merger with xAI and a potential initial public offering targeting a valuation over $1.7 trillion. Consistent successes with the Starlink constellation and the Starship program further cement the firm's role as a primary pillar of modern space infrastructure.

This episode explores the science and story behind Project Hail Mary, Andy Weir’s hit novel and its 2026 film adaptation starring Ryan Gosling. At the center is an unlikely hero, a middle school teacher sent on a last-ditch mission to save Earth from a mysterious organism that is dimming the sun. That same organism, called astrophage, may also be the key to interstellar travel.

We break down how the story leans on real physics, from time dilation to the challenges of deep space travel, and look at how accurate the science really is. We also dig into the idea of life beyond Earth, including the possibility of organisms that do not rely on water.

This episode traces the story of Mexico City—from the floating temples of Tenochtitlán to the sprawling metropolis it is today. We explore how the Spanish conquest reshaped the Aztec capital, how revolution and art gave rise to icons like Frida Kahlo and Diego Rivera, and how the city rebuilt itself through tragedy, from the Tlatelolco Massacre to the 1985 earthquake. In modern times, Mexico City has become a hub of progressive politics and cultural revival, constantly negotiating its indigenous roots, colonial past, and global future.

This episode unpacks China’s rise from a factory-driven economy to a global tech powerhouse. Through the lens of a three-part “Deep Dive” series, we explore how China’s political system has endured, how it’s shifting from low-cost manufacturing to sectors like EVs and AI, and what that means for the world economy. We dig into the country’s deep structural “endowments”—from human capital shaped by the one-child policy and Gaokao culture to its vast natural resources and rare earth dominance—and the challenges that shadow its success: aging demographics, a fragile safety net, and an urgent push toward electrification.

This episode traces the turbulent history of heart transplantation—from early animal experiments to Christiaan Barnard’s groundbreaking but short-lived surgery in 1967, through years of doubt and near-failure, to the game-changing arrival of cyclosporine in the 1980s. Along the way we revisit headline-making moments like Baby Fae’s baboon heart, today’s experimental pig transplants, and the ongoing struggle to expand donor pools. At its core, this is the story of how a once-impossible dream reshaped modern medicine, offering hope and new life to thousands despite enduring challenges.

We examine the Aalborg Zoo's controversial pet donation program, where members of the public can donate their domestic animals, such as guinea pigs, rabbits, chickens, and even small horses, to be humanely euthanized and used as food for the zoo's predators. The articles highlight the zoo's rationale that this practice mimics the natural food chain, ensuring the carnivores receive whole prey for optimal nutrition and natural behavior. While the program has generated significant backlash and international outrage, particularly from animal rights activists who question the ethics of using former pets as feed, the sources also present the zoo's defense, emphasizing its long-standing nature, legality within Denmark, and support from some locals who view it as a pragmatic and sustainable way to manage unwanted animals while preventing waste. Experts weigh in on the cultural differences in animal welfare perspectives and the often-hidden realities of feeding captive carnivores.

The history and politics of the dairy industry in the United States, particularly focusing on milk. We illustrate how milk, once a public health concern due to unsanitary practices, transformed into a perceived "superfood" through government intervention and extensive marketing campaigns. These efforts, ranging from early public health reforms and federal farm bills to iconic advertisements like "Got Milk?", aimed to boost consumption and stabilize prices, often involving significant taxpayer subsidies and aggressive lobbying. We also examine the challenges faced by the industry, including declining fluid milk consumption, the rise of plant-based alternatives, and growing concerns about the environmental impact and animal welfare of large-scale dairy farming, leading to ongoing debates about milk's role in nutrition and policy.
