The Mini: Living Underground

The crew revisits living underground, lunar lava tube safety, and drops into a science hole about a Stanford discovery that rewrites how we think life produces DNA

In Episode 65: “The Mini,” Joe, Nick, and Georgia recap Episode 64: Living Underground: Terrestrial and Extraterrestrial and still talking about their excitement for the Artemis II mission, which successfully flew around the Moon and back, with only a minor toilet malfunction along the way. They preview the upcoming planetary defense episode with guest Charles Blue, and break down what comes next in the Artemis program on the road back to the Moon.

Joe talks about the Catacombs of Paris, where a major renovation effort is modernizing one of the world’s most macabre tourist destinations, and the crew discusses lava tubes, moonquakes, and Georgia wonders what an atmosphere even is.

In Science Holes (the name of the current science research), Joe dives into a Stanford discovery that is challenging the foundations of molecular biology, a newly discovered bacterial defense system that breaks one of biology’s most fundamental rules. The crew connects it to CRISPR, bacteriophages, and Georgia has questions about gene editing approaches to treating sickle cell disease.

The crew closes out with what media they been consuming: For All Mankind season five, Daredevil: Born Again season two, Widow's Bay, Spaceballs, Community, the video game Phasmophobia, Free Comic Book Day at 10th Planet Comics, and books including Strange Animals, Strange Buildings, The Art Cure, Havana Hangover, and Absolution by Jeff VanderMeer. And Joe celebrates being named by the Guild Literary Complex as one of the 35 Writers to Watch!

The crew will be at the 5th Annual Mai Fest - Blue Island, IL (May 9th 12-5pm)

Joe will be one of 4 authors opening for a Blues Band: Avondalia Night Out - Rosa’s Lounge in Avondale, Chicago IL (May 14th 2026 7-8pm)- Joe reading

Science Holes:

1) Can a Renovation Breathe New Life Into Paris’s Home for the Dead?

For more than two centuries, tourists have descended beneath the streets of Paris to visit the Catacombs — a labyrinth housing the remains of up to six million Parisians. Over the past five months, architects, designers, technicians, and masons have been renovating the vast tomb, installing new lighting and ventilation systems, restoring the bone walls, and preparing new audio guides. Some areas previously unlit will now be visible to visitors for the first time.


2) Scientists Stunned by ‘Fundamentally New Way’ Life Produces DNA

Protein-templated synthesis of dinucleotide repeat DNA by an antiphage reverse transcriptase Authors: Pujuan Deng, Hyunbin Lee, Carlo Armijo, Haoqing Wang, and Alex Gao Published: April 16, 2026

A Stanford University team discovered a bacterial enzyme, Drt3b, that synthesizes DNA using its own protein structure as a blueprint — bypassing the traditional DNA→RNA→Protein central dogma entirely. Found in a bacterial defense system called DRT3, the enzyme protects bacteria from viral infection by producing repetitive DNA sequences without a nucleic acid template. Senior author Alex Gao called it “a fundamentally new way that life produces DNA.” The discovery could have practical applications in creating customized DNA strands and advanced biomaterials like DNA hydrogels.


3) Lyfgenia — FDA-Approved Gene Therapy for Sickle Cell Disease

Source: Infectious Disease Advisor

Lyfgenia (lovotibeglogene autotemcel) is a one-time FDA-approved gene therapy from bluebird bio for sickle cell disease in patients 12 and older. Unlike CRISPR-based approaches, it uses a lentiviral vector to insert a functional modified beta-globin gene into a patient’s own stem cells, which are then reintroduced into the bone marrow to produce healthy red blood cells.


4) The crew also noted that a separate CRISPR-based medicine for sickle cell was approved by the FDA in 2023.


Science Terms:

  • Amino acids — the building blocks of proteins; humans produce 11 of the 20 needed, the rest must come from food

  • Atmosphere — a layer of gases surrounding a planet, held in place by gravity, that provides protection, insulation, and the ability to retain water

  • Autosomal recessive — a pattern of inheritance where two copies of a mutated gene are needed to cause a disorder; sickle cell anemia is autosomal recessive

  • Bacteriophages — viruses that infect bacteria

  • Central dogma of molecular biology — the standard flow of genetic information: DNA is transcribed into RNA, which is translated into protein

  • CRISPR — a bacterial immune defense system that recognizes and cuts viral DNA; adapted by scientists as a precision gene editing tool

  • DNA (Deoxyribonucleic acid) — the hereditary material in cells that carries the genetic instructions for life

  • DNA hydrogels — advanced biomaterials made from DNA strands; a potential application of the Drt3b discovery

  • Drt3b — a newly discovered bacterial enzyme that uses its own protein structure as a template to synthesize DNA, bypassing the traditional rules of base pairing

  • Gene therapy — a medical technique that introduces, alters, or replaces genetic material within a person’s cells to treat disease

  • Hemoglobin / HBB gene — the protein in red blood cells that carries oxygen; a mutation in the HBB gene causes sickle cell anemia

  • Lentiviral vector — a modified virus used to safely deliver new genetic material into a patient’s cells

  • Lyfgenia (lovotibeglogene autotemcel) — an FDA-approved one-time gene therapy for sickle cell disease that uses a lentiviral vector to insert a functional beta-globin gene into a patient’s own stem cells

  • Messenger RNA (mRNA) — a molecule that carries genetic instructions from DNA in the nucleus out to the ribosomes where proteins are made

  • Moonquakes — seismic activity on the Moon, caused by factors including tidal forces from Earth and thermal expansion; different from earthquakes in origin and intensity

  • Phenotype — the observable physical traits of an organism resulting from its genetic makeup and environment

  • Protein — large molecules made of amino acid chains that carry out most of the work in cells, including building structures, catalyzing reactions, and regulating processes

  • Reverse transcriptase — an enzyme that synthesizes DNA from an RNA template; used by some viruses to replicate inside host cells

  • Ribosome — the cellular machinery that reads mRNA and assembles proteins from amino acids

  • RNA (Ribonucleic acid) — a molecule involved in coding, decoding, regulation, and expression of genes; messenger RNA carries instructions from DNA to ribosomes

  • Sickle cell anemia — a genetic disorder caused by a mutation in the HBB gene that causes red blood cells to form rigid crescent shapes, blocking blood flow and causing pain and organ damage

  • Stem cells — pluripotent cells that have not yet specialized and can be coaxed to develop into many different cell types; used in the Lyfgenia therapy

  • Transcription — the process by which DNA is copied into messenger RNA inside the cell nucleus

  • Translation — the process by which ribosomes read messenger RNA and assemble a corresponding chain of amino acids to build a protein
