Octopus Camouflage, Orcas vs. Sharks, Civet Coffee & Sub-Diffraction Telescope Tech (EP. 16)

From First Principles · Nov 13, 2025 · 1h 17m · transcript

Hosted by Lester Nare and Krishna Choudhary, this super-episode spans four wildly different frontiers: bioengineers hijacking bacterial evolution to mass-produce octopus camouflage pigment; orcas developing cultural hunting strategies against great white sharks; the bizarre chemistry behind civet-processed luxury coffee; and a UCLA breakthrough that pushes telescope resolution beyond the classical diffraction limit.

Summary

UCSD’s biosynthesis breakthrough — how researchers engineered a growth-coupled, plug-and-play metabolic pathway to mass-produce xanthomatin, the cephalopod pigment behind…
