From First Principles · Nov 27, 2025 · 1h 27m · transcript

Hosted by Lester Nare and Krishna Choudhary, this episode spans astrophysics, forensic chemistry, and neuroimmunology. We begin with a deep dive into 3I/ATLAS, only the third confirmed interstellar object to ever pass through our solar system — larger and stranger than ‘Oumuamua and Borisov, with new imagery released as NASA reopened operations. Then we break down a true-crime forensic breakthrough from Maynooth University that reveals how to recover fingerprints from fired bullet casings — a technique that could radically accelerate criminal investigations. And we close with a Max Planck…
