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
you see in soap films and (surprisingly) in the mathematics
behind string theory. Then we hit a neuroscience twist: even
simple jellyfish need sleep—and the evidence points to sleep as a
repair cycle for DNA damage. We close with
Cloud9, a newly characterized, starless gas
cloud that could be a rare “reionization-limited”
RELHIC—potentially exposing a dark matter halo without the glare
of stars.

Summary

String theory… in your body? Why real-world
transport networks converge toward minimal-energy geometry—and
what that has to do with string-theory math and 120° branching
angles.

Jellyfish need sleep (and it’s not optional):
Evidence that sleep pressure tracks cellular stress and DNA
damage repair—even in a brainless animal.

Cloud9: A nearby starless cloud that may be a
dark matter halo in plain sight—plus what it implies about
“missing” galaxies and the post-reionization universe.

The Rundown: iron asteroids, artificial
metabolism (ReForm), scalable helper T-cells from stem cells,
and NASA’s Pandora exoplanet mission.
