From First Principles

Dark Galaxies, Fuzzy Dark Matter, and an Alzheimer’s Breakthrough (EP. 28)

Hosted by Lester Nare and Krishna Choudhary, this episode has two main stories: an astrophysics update on a candidate “dark galaxy” in the Perseus Cluster (a halo that’s ~99.9% dark matter), and a major Alzheimer’s mechanism paper tracing how exercise protects the brain by repairing the blood–brain barrier—with an actionable drug-like path already emerging.SummaryCandidate dark galaxy — Hubble + Euclid stacking and globular clusters reveal an ultra-faint halo that could test missing satellites and the cusp–core problem (and even “fuzzy dark matter”).Exercise → Alzheimer’s mechanism — UCSF links a liver enzyme (GPLD1) to BBB repair via TNAP regulation, plus an oral TNAP inhibitor (SBI-425) that mimics the effect in mice.Rundown — Rubin Observatory’s real-time alert engine, AI-accelerated magnet discovery, a climate-corrected Easter Island history, and the Boba-Kiki effect in baby chicks.Support the showDonate: FFPod.com/donateFollow: @FFPod (X / Instagram / TikTok / Facebook)

Dream Engineering, the Proton Radius Puzzle, and an ALS Breakthrough (EP. 27)

Hosted by Lester Nare and Krishna Choudhary, this episode has three main stories: interactive dream engineering (yes, two-way “communication” during lucid dreaming), the proton radius puzzle finally getting resolved by a precision lab measurement, and a sobering but hopeful look at ALS—including a breakthrough “ALS-in-a-dish” model that could finally make drug screening translate to humans.SummaryDream engineering — targeted cues + induced lucidity → dream-content biasing and measurable next-day performance gains.Proton radius puzzle — precision hydrogen spectroscopy resolves the decade-long discrepancy; normal hydrogen agrees with muonic hydrogen.ALS — a predictive iPSC motor-neuron model that correlates with patient survival and reveals a promising multi-drug synergy.Rundown — pulsar near the Milky Way center, AI decoding a Roman board game, hormones + evolution signals, and AI-in-the-loop protein engineering.Support the showDonate: FFPod.com/donateFollow: @FFPod (X / Instagram / TikTok / Facebook)

Winter Olympics Deep Dive: Ice Physics, Performance Pressure, and Climate Change (EP. 26)

Hosted by Lester Nare and Krishna Choudhary, this episode is a Winter Olympics deep dive from first principles—physics, neuroscience, and climate science in one ride.• Why ice is slippery: the “water layer” story is incomplete—new nanoscale measurements suggest a far more viscous, thicker interfacial film than textbook intuition.• Choking under pressure: how high stakes can disrupt neural control—reward signals can push brain states out of the “optimal zone.”• Climate change vs winter sports: why artificial snow has limits, why some legacy venues may become unreliable, and what “snow farming” is trying to solve.• Rundown: AI doing physics proofs, cat vocalizations, immune epigenetics, origin-of-life genetics, and an “impossible” exoplanet system.Support the show: FFPpod.com/donateFollow: @FFPod (X / Instagram / TikTok / Facebook)00:00 Intro00:32 Episode setup02:15 Why is ice slippery?33:23 Rundown + housekeeping + donate01:09:11 Choking under pressure (neuroscience)01:32:32 Climate change & the Winter Olympics + potpourri01:43:47 Wrap-up + closing

Plants, Quantum Sensors, and Predicting Cancer Evolution (EP. 25)

Hosted by Lester Nare and Krishna Choudhary, this episode jumps from plant biochemistry to quantum metrology to cancer evolution. We start with a University of York breakthrough that solves a ~50-year mystery in alkaloid biosynthesis—identifying the “missing” enzyme behind a key asymmetric step plants use to build powerful defensive (and pharmaceutically useful) molecules. Then we go deep on quantum sensing with entangled atomic clouds, showing how correlated measurements can beat the standard quantum limit. Finally, we close with ALFA-K, a new tool that maps local fitness landscapes to predict how aneuploid cancers may evolve under pressure from therapy.SummaryPlants making medicines — the “phantom enzyme” in alkaloid biosynthesis and why solving this pathway matters for scalable drug production.Quantum measurements with entangled atom clouds — squeezed/entangled states, noise reduction, and why correlations unlock better sensing.Predicting cancer evolution — ALFA-K and measurable fitness landscapes for aneuploidy-driven trajectories under treatment.Show NotesStory 1 — Plant alkaloid biosynthesis (University of York)Paper — New PhytologistStory 2 — Quantum measurements with entangled atomic clouds (University of Basel)Paper — ScienceStory 3 — Alpha-K (Moffitt Cancer Center)Paper — Nature Communications

Artemis II, Apollo, and the Physics of Going Back to the Moon (EP. 24)

Hosted by Lester Nare and Krishna Choudhary, this episode is a full-spectrum moonshot: why Artemis II matters, how the mission actually works (SLS, Orion, translunar injection, free-return trajectories), and a first-principles teardown of the most common Apollo “hoax” claims—Van Allen belts, waving flags, shadows, and “why aren’t there stars?”We also run a quick Rundown of wild science headlines (ancient cave art, elevation-dependent warming, dogs and vocabulary, and peptide bonds in deep space), before coming back to the core question: what it takes to send humans safely around the Moon—again.SummaryArtemis II mission profile — what “free return” means, why TLI timing matters, and what Orion is doing in high Earth orbit before the Moon.SLS vs Saturn V — the engineering and risk trade-offs behind modern human-rated heavy lift.Apollo myths, explained — radiation belts, camera exposure physics, and why the “flag,” “shadows,” and “no stars” arguments don’t survive basic mechanics and optics.Proof Apollo happened — retroreflectors, orbital imagery, and the reality that the world was watching.Show NotesNASA Artemis ProgramNASA Orion SpacecraftNASA Space Launch System (SLS)NASA Apollo 11 Mission Overview
