Hacking The Human Brain, Unlocking Our Ape DNA, Forging Unbreakable Diamonds & The Quantum Magician
This week we break down four big stories—no PhD required.Reading “inner speech”: Invasive brain–computer interfaces record neurons in motor cortex and decode attempted vs. inner speech into words. Results from Stanford even generalize to simple symbols and numbers. Cool science, huge privacy questions, and a proposed “brain password” to keep users in control.What makes us human: UC San Diego highlights human accelerated regions (HARs)—genomic control switches (promoters/enhancers) that tune when and where genes are used. We revisit classic HAR examples and a new result connecting a specific HAR to brain development.Diamonds get an upgrade: Scientists at HPSTAR (Beijing) grow stronger lab diamonds with clear industrial upside—from cutting tools to power electronics—and potential to reduce harmful mining incentives.International Year of Quantum (2025): A fast retrospective on 100 years of quantum mechanics and how today’s quantum tech is reshaping computing, sensing, and materials.Hosts: Lester Nare & Dr. Krishna ChoudharyShow: From First Principles Podcast

3rd Interstellar Visitor, Rubin’s Sky Camera, AI CRISPR Boost & T. rex Blood Vessels
Interstellar visitor #3 is here. We unpack 3I ATLAS (why it’s moving so fast, why we finally saw a tail, and how Hubble/JWST—and maybe even Juno—could nail down its makeup). Then we dive into the Vera Rubin Observatory, the 32-gigapixel camera that will turn the entire sky into a time-lapse movie and supercharge discovery. Next: AI just boosted CRISPR by predicting and guiding DNA repair (Pythia), making edits cleaner—especially in non-dividing neurons. And we close with a crossover of dinos + particle physics: preserved T. rex blood vessels revealed by a synchrotron. Mystery Box: the viral “Black aliens” meme.

Oldest Molecule, Programmable Proteins, Europa Radar & Light’s Double Life
We go from the universe’s first chemistry to tomorrow’s designer biology, swing by Mars to tune Europa Clipper’s ice radar, and finish with a fresh take on the double-slit experiment.In this episodeThe “oldest molecule” puzzle (HeH⁺), cooling the early universe, and why JWST’s findings matterProgrammable proteins: reassigning codons, recoding organisms, and real biosafetyEuropa Clipper’s REASON radar test at Mars: frequencies, ice thickness & ocean cluesDouble-slit, demystified: single photons, “which-path” info, and measurement realityChapters00:00 Intro • 01:26 First molecule • 22:27 Programmable proteins • 43:05 Europa radar • 55:00 Double-slit • 1:15:03 Sign-off

Earth’s 1-ms Day, Baby Solar Systems, Record Black Hole Crash, CRISPR Cancer Hack & AI Indiana Jones
Last week the Earth finished a full rotation one millisecond early – but that’s just the opener.In this week’s From First Principles we dive into six mind-bending headlines with our trademark mix of hard science and light-hearted banter:Earth’s fastest spin ever recorded – what shaved a millisecond off the day and why your chakras are still safe.ALMA spots a “baby Earth” forming 1,300 light years away – the first direct look at rocky planets in the making.Biggest black-hole merger on record – 15 ☉ of mass vaporized into pure gravitational waves, detected by LIGO/Virgo/KAGRA.CRISPR reveals a vitamin-D “kill switch” for tumors – how silencing one gene in pancreatic & colon cancers triggers 4,000 downstream changes.A star that died… then died again – the first confirmed “double-detonation” white-dwarf supernova.DeepMind’s Aeneas AI deciphers broken Latin tablets – giving historians new text, provenance and dating in seconds.👋 Hosts • Lester Nare – storyteller & professional curiosity machine • Dr. Krishna Choudhary – Princeton-trained physicist & cosmic tour guide👍 Like what you hear?
