5,000-Year-Old Bacteria, Solar Storms, Dogs, and Meta’s AI War (EP. 32) 20.03.2026

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 fo...

Optovolution: Teaching Proteins to Think Like Computers (EP. 31) 18.03.2026

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. Thi...

Can We Stop an Asteroid? The Physics Behind NASA’s DART Mission (EP. 30) 16.03.2026

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 pa...

Astrobiology’s Biggest Survival Test + A Vaccine Against Everything? (EP. 29) 12.03.2026

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 vaccin...

Dark Galaxies, Fuzzy Dark Matter, and an Alzheimer’s Breakthrough (EP. 28) 04.03.2026

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. Summary Candidate dark galaxy — Hubble...

Dream Engineering, the Proton Radius Puzzle, and an ALS Breakthrough (EP. 27) 26.02.2026

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. Summ...

Winter Olympics Deep Dive: Ice Physics, Performance Pressure, and Climate Change (EP. 26) 18.02.2026

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 contro...

Plants, Quantum Sensors, and Predicting Cancer Evolution (EP. 25) 10.02.2026

Hosted by Lester Nare and Krishna Choudhary , this episode jumps from plant biochemistry to quantum metrology to cancer evolution.

Then we go deep on quan...

Artemis II, Apollo, and the Physics of Going Back to the Moon (EP. 24) 04.02.2026

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...

JWST’s “Little Red Dots,” TimeVaults, and the Dawn of Math (EP. 23) 27.01.2026

Hosted by Lester Nare and Krishna Choudhary , this episode runs from JWST’s “Little Red Dots” (and what they imply about early supermassive black holes), to a TimeVault method for recording gene expression over time , to 8,000-year-old Halaf pottery that may encode geometric sequences — plus a quick Cloud9 follow-up on the “starless dark-matter halo” debate. Summary JWST’s Little Red Dots — why th...

Cloud9 Dark Matter Halo, Jellyfish Sleep, and String Theory Hidden in Nature (EP. 22) 20.01.2026

Hosted by Lester Nare and Krishna Choudhary , this episode runs from the deep math of string theory to the biology of sleep—then out to a starless “ghost cloud” that may be a naked dark-matter halo. We open with a Nature paper showing that physical networks in nature (brains, blood vessels, fungal networks) appear to organize like energy-minimizing surfaces—spitting out the same branching rules yo...

Roman Concrete, Brain “Cognitive Legos,” DeepSeek, and Econophysics (EP. 21) 12.01.2026

Hosted by Lester Nare and Krishna Choudhary , this episode jumps from ancient engineering to modern AI and markets. We start with the newly uncovered Pompeii worksite that finally shows how Romans mixed their concrete — and why it “self-heals.” Then we pivot into a Princeton neuroscience idea that the brain builds complex thought like LEGO bricks (compositional neural subspaces). From there, we br...

The Physics Behind Fusion’s Biggest Problem (Season Finale) (EP. 20) 23.12.2025

Hosted by Lester Nare and Krishna Choudhary , this Season Finale closes out Season 1 with a deep dive into the physics behind fusion’s biggest bottleneck: fast magnetic reconnection . We unpack why classic models predicted reconnection should be slow, why nature (and tokamaks) disagree, and how modern “plasmoid” reconnection helps explain solar flares, plasma instabilities, and the real engineerin...
