Feb 9, 2026 A historical hunt for soil microbes that yielded most modern antibiotics. Tales of serendipitous mold finds and systematic streptomyces screening. Global expeditions and massive manual plate testing that peaked then waned. The rise of resistance, pivots to semi-synthesis, and the widening gap between scientific need and economic incentives.

Episode notes
Golden Age Condensed Into Two Decades
- Over half of today's therapeutic antibiotics were discovered within a 20-year window in the mid-20th century.
- That burst began after penicillin's therapeutic success and a systematic screening approach emerged.
Fleming's Accidental Observation
- Alexander Fleming noticed mold killing bacteria in 1928 but failed to isolate it, so his paper went largely ignored.
- Oxford scientists later purified penicillin and turned it into a lifesaving therapeutic in 1943.
Waksman's Systematic Soil Campaign
- Selman Waksman organized systematic soil screening and urged students to isolate streptomyces for new antibiotics.
- His team discovered streptomycin but a dispute over credit led to lawsuits and Nobel controversy.
