• The Physics of the World Cup: VAR, Smart Balls, and Soccer Aerodynamics (EP 45) 29.06.2026 59Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is our World Cup special — a deep dive into the science, physics, engineering, and data behind the beautiful game.We start with the offside rule and the controversy around semi-automated VAR. How can a system decide whether a player is onside or offside by only a few inches? Krishna breaks the problem down like an experimental physicist: player speed, ball-contact time, camera frame rate, significant digits, and the error budget behind the line on screen. From there, we get into the actual technology: player tracking, digital twins, high-resolution cameras, and the connected match ball sensor that helps determine when the pass was played.Then we move from refereeing technology to the ball itself. Why does the 2026 World Cup ball look the way it does? How do Platonic solids, panel geometry, and surface seams affect the way a soccer ball flies? And why was the 2010 Jabulani ball so controversial? We go through drag, drag coefficients, wind tunnels, the drag crisis, golf ball dimples, and why the roughness of a ball can completely change its trajectory.Finally, we look at the hidden engineering of the World Cup pitch — real grass in NFL stadiums, LED grow lights, drainage systems, turfgrass science, and even 3D-printed cleat-foot testing devices — before ending with match momentum, possession value, hydration breaks, and the data science behind modern football analytics.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesSemi-automated offside technology and connected-ball systemsAdidas Trionda — official 2026 World Cup match ballAerodynamics of World Cup balls and the Jabulani drag-crisis controversyWorld Cup 2026 pitch engineering and turfgrass researchPossession value and match momentum in football analytics
• New Rules For Heredity (Non-Mendelian Inheritance of Epigenetics) (EP 44) 26.06.2026 1Std. 37Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode marks Krishna’s return to the studio after paternity leave — and the timing could not be more fitting. Today’s deep dive is about inheritance: not just the classic Mendelian rules most of us learned in biology class, but the stranger, more dynamic world of non-Mendelian epigenetic inheritance.Starting from Gregor Mendel and his pea plants, Lester and Krishna rebuild the foundations of genetics from first principles: dominant and recessive alleles, Punnett squares, chromosomes, fruit flies, DNA, and the physical mechanism behind inherited traits. Then they move into the “software layer” of biology: epigenetics, DNA methylation, chromatin packaging, RNA interference, and paramutation — cases where the genetic code is present, but the cell’s machinery silences or rewrites how that code is used.The episode centers on a new Nature Genetics paper, “Non-Mendelian inheritance of DNA methylation patterns in mice,” which suggests that non-Mendelian epigenetic inheritance may be more widespread in mammals than previously understood. The conversation also covers why Oxford Nanopore sequencing made this kind of analysis possible, why methylation patterns can be hard to trace across generations, and what all of this could mean for disease risk, drug response, sex differences, evolution, and the long-running nature-versus-nurture debate.Summary Mendel’s rules — how pea plants, true-breeding lines, dominant and recessive traits, and Punnett squares gave us the first mathematical laws of inheritance. The first cracks in Mendel — how chromosomes, fruit flies, sex-linked traits, and linked genes showed that inheritance is more complicated than independent assortment. DNA as hardware, epigenetics as software — why having a gene is not the same thing as expressing it, and how methylation and chromatin packaging can silence parts of the genome. Paramutation — how one allele can change the expression state of another allele across generations, creating inheritance patterns that do not follow standard Mendelian expectations. Oxford Nanopore and the technology shift — why long-read sequencing and direct methylation detection make it possible to trace epigenetic marks back to the parent they came from. The mouse methylation paper — how researchers used collaborative cross mice to show that most methylation inheritance looks Mendelian, but a meaningful fraction appears to follow stranger non-Mendelian rules. Why it matters — potential implications for clinical genetics, disease risk, drug efficacy, sex-specific biology, and the relationship between nature and nurture.

• Dr. Michael Blanton on Open Data, Galaxy Surveys, and the Future of Astronomy (EP 43) 04.06.2026 43Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is the second interview in our ongoing collaboration series with Carnegie Observatories. Krishna sits down with Dr. Michael Blanton, the new Director of the Carnegie Observatories, for a wide-ranging conversation on how astronomy became one of the most data-rich sciences, how the Sloan Digital Sky Survey helped change the culture around open data, what the next era of astronomical data science and AI could look like, and one of the galaxy mysteries Blanton still wants to solve: why the most massive galaxies in the universe stop forming stars.The conversation starts with Blanton’s Princeton roots and his work connected to the Sloan Digital Sky Survey, then moves into the culture of public astronomical data, the NYU Value-Added Galaxy Catalog, Vera Rubin Observatory, Carnegie’s role in the future of astronomy, the Magellan telescopes, astronomical archives, MaNGA and eBOSS, galaxy formation, dark matter, and even the science behind the black hole visualizations in Interstellar.Audio note: this was one of our first out-of-studio interviews, and there are a few minor audio issues in parts of the conversation. We appreciate your patience, and we’ll be better prepared for future field interviews.Also, if you’re in Los Angeles, Krishna will be giving a talk at Exploring Physics at UCLA, hosted by UCLA’s physics outreach organization Continuum, on Saturday, June 6 at the Fowler Museum.

• How Scientists Actually Study Dark Matter (EP 42) 21.05.2026 1Std. 6Min.

  Hosted by Lester Nare, this episode features astrophysicist Dan Gilman for a deep conversation on one of the biggest open questions in modern physics: what dark matter actually is. Starting from first principles, Lester and Dan walk through why the evidence for dark matter is now so strong, how strong gravitational lensing works, why tiny distortions in lensed light can reveal invisible clumps of matter, and how the next generation of surveys may transform the field. Krishna is out on family leave for this one, but the conversation stays fully in the From First Principles lane: grounded, visual, and science-first.SummaryWhat dark matter is — Dan explains the basic case for dark matter, why it appears to interact only through gravity, and why multiple independent observations now point to the same conclusion.How strong gravitational lensing helps — the episode uses intuitive analogies like tides, fish tanks, and flashlights to explain how astronomers can infer the presence and structure of dark matter without seeing it directly.What Dan actually studies — the core of Dan’s work is building and testing simulations of lensed systems to see which dark matter theories best match reality.Why the next few years matter — Rubin, Roman, Euclid, and AI-assisted lens finding could dramatically increase the number of usable lens systems and sharpen the search for dark matter’s fundamental nature.Show NotesDan Gilman on strong gravitational lensing and dark matter substructureEuclid mission overviewRubin Observatory overviewRoman Space Telescope mission context
• Dr. John Mulchaey on Carnegie Science and the Future of Astronomy (EP 41) 13.05.2026 37Min.

  Hosted by Lester Nare and Krishna Choudhary, this interview features John Mulchaey, the 12th President of Carnegie Science and former Director of the Carnegie Observatories. The conversation starts with his early work on galaxy groups and dark matter, then expands into how Carnegie works as a scientific institution, what the Giant Magellan Telescope could unlock for exoplanets and astronomy, how science funding actually works, and why eclipse chasing is still one of the most magical experiences in science.SummaryGalaxy groups and dark matter — Mulchaey explains why small galaxy groups matter more than most people realize, and how X-ray observations of hot gas helped make their masses measurable.Carnegie’s model — the interview gets into what makes Carnegie unusual: scientific freedom, long time horizons, and room to pursue surprising questions.The Giant Magellan Telescope — a look at why bigger telescopes matter, what GMT changes, and why exoplanet atmospheres are one of the biggest goals ahead.The bigger picture — science funding, philanthropy, how astronomy has changed, and why total solar eclipses still inspire so many astronomers.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesJohn Mulchaey leadership bio — Carnegie Sciencehttps://carnegiescience.edu/about/leadershipCarnegie Science appoints John Mulchaey as its 12th Presidenthttps://carnegiescience.edu/news/carnegie-science-appoints-john-mulchaey-its-12th-presidentGiant Magellan Telescope — official overviewhttps://giantmagellan.org/about-us/1993 NASA write-up on Mulchaey’s dark matter result in galaxy groupshttps://science.nasa.gov/missions/hubble/dark-matter-found-in-a-typical-cluster-of-galaxies/Carnegie Science Great North American Eclipse outreach recaphttps://carnegiescience.edu/yearbook/2024/science/great-north-american-eclipsePerot Museum eclipse partnership recaphttps://www.perotmuseum.org/events/solar-eclipses/
• Ant Scans, Lunar Chickpeas, Hidden Galaxies & Superconductivity (EP 40) 29.04.2026 36Min.

  Hosted by Lester Nare and Krishna Choudhary, this rundown episode covers four new science stories at a high level: a huge new 3D ant imaging database built with synchrotron X-ray microtomography, a lunar agriculture experiment that grew chickpeas in simulated moon soil using fungi and worm waste, AI-assisted discovery of strange objects in the Hubble archive, and a new programmatic roadmap for room-temperature superconductivity. There is also another round of Are You Smarter Than a Scientist? in the middle.SummaryParticle accelerators meet biodiversity — researchers built a massive high-resolution ant imaging resource, covering nearly 800 species and thousands of specimens, with AI-assisted 3D reconstruction.Moon farming gets weird — chickpeas were grown in lunar regolith simulant with help from mycorrhizal fungi and worm-derived compost, a first step toward sustainable off-world agriculture.AI found hidden anomalies in Hubble’s archive — AnomalyMatch sifted through roughly 100 million source cutouts in just days and surfaced new candidate lenses, mergers, and other rare objects.The superconductivity long game — a new PNAS perspective argues that room-temperature superconductivity is not ruled out by physics, and calls for a coordinated push to get there.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesHigh-throughput phenomics of global ant biodiversity — Nature MethodsBioremediation of lunar regolith simulant through mycorrhizal fungi and plant symbioses enables chickpea to seed — Scientific ReportsIdentifying astrophysical anomalies in 99.6 million source cutouts from the Hubble legacy archive using AnomalyMatch — Astronomy & AstrophysicsThe path to room-temperature superconductivity: A programmatic approach — PNAS
• The Prometheus Constellation: Dramaturgical and Scientific Analysis of the Physicists in Oppenheimer (EP 39) 21.04.2026 1Std. 37Min.

  Hosted by Lester Nare and Krishna Choudhary, this special episode ranks the 26 scientists shown in Christopher Nolan’s Oppenheimer by one standard only: their contribution to fundamental science. Starting with the Manhattan Project figures near the bottom and working up through the giants of quantum mechanics, relativity, nuclear physics, and logic, the episode turns a movie cast list into a surprisingly deep walk through the history of modern physics.SummaryA ranking framework that actually means something — this list is based on scientific achievement, not movie prominence, clout, or vibes.A tour of 20th-century science — from nuclear chain reactions and black holes to MRI, GPS, quantum mechanics, and information theory.The great debates — several placements are designed to provoke real argument, especially around how Oppenheimer compares to the physicists around him.A top tier full of monsters — the back half of the episode becomes a speedrun through some of the most influential scientific minds of the modern era.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / Facebook
• Harder Than Diamond? The New Hexagonal Diamond Breakthrough (EP 38) 15.04.2026 57Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a deep dive into one of the strangest and most hard-fought materials science stories in decades: the claim that researchers have finally synthesized bulk hexagonal diamond, also known as lonsdaleite. They break down why this material matters, how it differs from ordinary cubic diamond, why scientists argued about its existence for more than 50 years, and what the new Nature paper actually did to convince skeptical reviewers.SummaryWhy hexagonal diamond matters — if real, it is a long-sought carbon phase that could be slightly harder than conventional diamond and useful in extreme industrial settings.The first-principles chemistry — carbon allotropes, x-ray crystallography, cubic diamond, and the ABAB stacking that makes hexagonal diamond different.The experimental breakthrough — how the new team engineered around the default pathway to ordinary diamond by controlling graphite orientation and pressure direction.The controversy — why the peer review was intense, and how the new paper relates to an earlier 2025 Nature paper with a similar claim.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / Facebook
• Artemis II: Deep Dive on the Moon Flyby, Earthset, and Reentry (EP 37) 09.04.2026 1Std. 25Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a full deep dive on Artemis II as the crew returns from humanity’s first crewed lunar flyby in more than 50 years. Lester and Krishna break down the mission photo by photo, from launch and translunar injection to Earthset, Earthrise, the in-space solar eclipse, the science of lunar observations, and the skip-entry reentry profile bringing Orion home.SummaryWhy Artemis II is historic, what the crew saw on the far side of the Moon, and why this mission matters for the long-term return to the lunar surface.Why NASA relied on the Nikon D5 for deep-space photography, and what camera physics, low-light performance, and radiation tolerance have to do with getting these images home.The standout observations from the flyby: Earthset, Earthrise, a rare in-space solar eclipse, planetary alignment during eclipse, and the first crewed visual observations of meteoroid impact flashes on the Moon.How Orion’s reentry works, why Artemis II uses skip entry, what happened to Artemis I’s heat shield, and what NASA changed for the crewed return.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / Facebook

• Can AI Help Wake Coma Patients? The Science of Consciousness (EP 35) 31.03.2026 1Std. 8Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a deep dive into one of the hardest questions in neuroscience: what breaks in the brain during a coma, and can we figure out how to turn consciousness back on? We unpack a new paper from Daniel Toker et al. that uses an interpretable AI framework — not a generic black box chatbot model — to reverse engineer the biological mechanisms of prolonged unconsciousness, recover known features of coma, predict new ones, and propose a possible new target for deep brain stimulation.SummaryWhy diagnosis is so hard — disorders of consciousness are not just about whether a patient is awake, but whether awareness is still present even when motor output is gone.The mesocircuit hypothesis — the episode explains how the cortex, thalamus, and basal ganglia may work together like an electrical grid to support consciousness.Interpretable AI, not black-box hype — Daniel Toker’s team built a biophysically grounded model that rediscovered known coma features and predicted two new biological mechanisms.A possible stimulation target — the subthalamic nucleus emerged as a standout candidate for deep brain stimulation, suggesting a new path toward restoring wakefulness.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesDaniel Toker et al. — Adversarial AI reveals mechanisms and treatments for disorders of consciousnessNicholas Schiff et al. — deep brain stimulation in a minimally conscious patientAdrian Owen et al. — fMRI evidence of covert awareness in a patient diagnosed as vegetative
• AI Cancer Vaccines, Strange Fish, Ketamine, and Ancient Life (EP. 34) 27.03.2026 44Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a fast-moving science rundown covering four remarkable stories from across AI, genetics, neuroscience, and paleontology. We dig into the story of a machine learning engineer who used AI tools to help design a personalized cancer vaccine for his dog, explore how an all-female fish species has survived far longer than evolutionary theory would predict, unpack new brain-scan evidence for how ketamine may rapidly relieve severe depression, and look at new research suggesting life rebounded shockingly fast after the asteroid that killed the dinosaurs.SummaryAI and personalized medicine — a striking case study in how AI tools may help accelerate highly customized treatments, starting with a rescue dog named Rosie.Evolution gets weird — the Amazon molly fish appears to challenge the usual assumptions about why asexual reproduction should fail over long time scales.Why ketamine works so fast — new PET imaging research points to brain-region-specific changes in AMPA receptors in treatment-resistant depression.Life after catastrophe — microscopic plankton may have evolved into new species within just a few thousand years after the Chicxulub impact.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesAI-designed dog cancer vaccine storyhttps://finance.yahoo.com/news/mans-dog-riddled-tumors-dying-210500037.html?guccounter=1Amazon molly / gene conversion paperhttps://www.nature.com/articles/s41586-026-10180-9Ketamine / AMPA receptor PET imaging paperhttps://www.nature.com/articles/s41380-026-03510-wPost-asteroid plankton recovery paperhttps://www.yokohama-cu.ac.jp/english/news/20260306takahashi.html
• Can Human Neurons Really Play Doom? The Science Behind Wetware (EP. 33) 24.03.2026 1Std. 13Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a deep dive into one of the strangest science stories of the year: a dish of human neurons allegedly learning to play Doom. We go back to the original 2022 DishBrain paper out of Cortical Labs, unpack how biological neurons can be read and written with multi-electrode arrays, and then compare the peer-reviewed Pong result to the much newer Doom claim. The result is a story that is both genuinely impressive and, in places, probably overhyped.SummaryWetware engineering — replacing artificial neurons with real biological neurons plus electronics, and why some people think this could become a new computing paradigm.How DishBrain worked — human stem-cell-derived cortical neurons grown on a multi-electrode array, trained through sensory encoding and a “minimize surprise” feedback loop.Where the Doom story gets messy — the newer system appears to include a reinforcement-learning layer in the loop, raising the key question: are the neurons actually doing the learning?The big idea underneath the hype — even if Doom is overstated, the broader platform is still a remarkable step toward programmable biocomputing.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / Facebook
• 5,000-Year-Old Bacteria, Solar Storms, Dogs, and Meta’s AI War (EP. 32) 20.03.2026 38Min.

  Hosted by Lester Nare and Krishna Choudhary, this is our first standalone rundown episode — a faster, looser format where we hit several stories we didn’t have room to turn into full deep dives. This week: bacteria revived from a Romanian ice cave after 5,000 years, a speculative but fascinating theory linking solar storms to earthquakes, new evidence that dogs and humans share genetic roots for personality traits, and the increasingly dramatic fight over the future of AI after Yann LeCun leaves Meta to build a new billion-dollar company focused on world models.SummaryAncient bacteria, modern resistance — a microbe revived from a 5,000-year-old Romanian ice cave resists modern antibiotics and may even contain compounds useful against present-day superbugs.Solar storms and earthquakes? — a Kyoto University theoretical paper suggests space weather could perturb electric fields in Earth’s crust enough to influence faults already near critical stress.Dogs and humans, genetically — a Cambridge / Morris Animal Foundation study finds shared gene pathways that map to personality-like traits in both golden retrievers and humans.The Meta AI split — Yann LeCun leaves Meta to pursue AI systems that model the physical world, arguing that simple scaling of LLMs may never reach real general intelligence.Support the showDonate: FFPod.com/donateFollow: @FFPod (X / Instagram / TikTok / Facebook)Show NotesStory 1 — Ancient bacteria in Romanian ice cave (Frontiers in Microbiology)Story 2 — Solar storms and earthquakes (Kyoto University / International Journal of Plasma Environmental Science and Technology)Story 4 — Dog and human personality genes (PNAS)Story 5 — Yann LeCun leaves Meta / world-model AI (Wired)
• Optovolution: Teaching Proteins to Think Like Computers (EP. 31) 18.03.2026 55Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a deep dive into a new synthetic-biology breakthrough out of EPFL: OptoEvolution. The big idea is simple but powerful — traditional directed evolution is great at making proteins that are always “on,” but biology is full of proteins that need to switch states, respond to stimuli, and behave more like logic gates than static tools. This paper takes directed evolution and couples it to light and the cell cycle, creating a new way to evolve dynamic proteins that can toggle, compute, and respond with far more control.SummaryWhy directed evolution needed an upgrade — classic methods select for proteins with continuous function, not proteins that toggle between active and inactive states.OptoEvolution — using light as a control signal and the cell cycle as a built-in oscillator to evolve proteins that must turn on and off to survive.Color-multiplexed biology — engineering proteins to respond to different wavelengths of light, opening the door to finer control of gene expression.Single-protein logic gates — proof-of-concept AND-gate behavior inside a single protein, hinting at a future where biology can be programmed with much more software-like precision.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookShow NotesOptoEvolution / dynamic protein control (Cell)
• Can We Stop an Asteroid? The Physics Behind NASA’s DART Mission (EP. 30) 16.03.2026 54Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode is a full deep dive on planetary defense. We break down NASA’s DART mission, why the goal was never to “blow up” an asteroid but to gently nudge it, and why the newest result is even bigger than the original headline: scientists can now directly detect that the Didymos–Dimorphos system changed not just locally, but in its heliocentric path around the Sun.Summary DART actually worked — not just by shortening Dimorphos’s local orbit around Didymos by 33 minutes, but by measurably changing the motion of the whole binary system around the Sun. Planetary defense is a measurement problem — the new result hinges on detecting a velocity shift of just 11 microns per second in an asteroid system moving tens of kilometers per second. Why ejecta matters — the impact transferred more momentum than the spacecraft carried in, thanks to debris blasting off the asteroid and boosting the total deflection. Why this matters for Earth — for the first time in our planet’s history, life on Earth may actually have the tools to alter its own cosmic fate.Support the showDonate: FFPod.com/donateFollow: @FFPod on X / Instagram / TikTok / FacebookChapters 00:00 New single-story format 01:53 DART mission setup 18:26 Why the binary asteroid system matters 31:36 Measuring the heliocentric deflection 46:28 Planetary defense implications 53:37 OutroShow Notes DART heliocentric deflection result — Science Advances NASA DART mission overview ESA HERA mission
• Astrobiology’s Biggest Survival Test + A Vaccine Against Everything? (EP. 29) 12.03.2026 2Std. 4Min.

  Hosted by Lester Nare and Krishna Choudhary, this episode starts in astrobiology with a fresh experimental challenge to one of the biggest objections to lithopanspermia: can life actually survive the violence of being blasted off a planet by an asteroid impact? Then, after a packed Rundown, we pivot hard into immunology with a radical Stanford paper asking whether we could build one nasal vaccine that doesn’t target a specific pathogen at all—but instead makes the lung itself a stronger fortress against whatever shows up.SummaryLithopanspermia gets less crazy — a Johns Hopkins / PNAS Nexus study tests whether extremely resilient microbes can survive the initial shock of ejection from a planet, potentially closing the last major bottleneck in rock-to-rock transfer of life.The universal-vaccine idea — instead of training the adaptive immune system on one pathogen, Stanford asks whether the lung itself can be preconditioned to respond broadly and rapidly to many threats.The Rundown — AI for materials science, orbital nuclear conflict simulations, and other frontier stories the guys wanted to hit even without full deep dives.Support the showDonate: FFPod.com/donateFollow: @FFPod (X / Instagram / TikTok / Facebook)Show NotesLithopanspermia / impact survival (PNAS Nexus, Johns Hopkins)https://academic.oup.com/pnasnexus/article/5/3/pgag018/8503064Pathogen-agnostic nasal vaccine (Science, Stanford)https://www.science.org/doi/10.1126/science.aea1260
