10 Million Deaths Predicted But Science Is Fighting Back! The Secret Gut Viruses That Attack Cancer, Fight Infection and Slow Aging

Prof. Martha Clokie, Prof. Tim Spector
Show Notes

Professors Martha Clokie and Tim Spector explore bacteriophages—viruses that live in the gut and attack bacteria—as a potential solution to antibiotic resistance, which could kill 10 million people annually if left unchecked. The episode examines how phages may fight infection, target cancer cells, and protect the microbiome, while discussing why antibiotic resistance has become a critical global threat and what everyday choices can support a healthier gut ecosystem.

Bacteriophages: Viruses That Attack Bacteria, Not Humans03:19
Bacteriophages are viruses that specifically target and kill bacteria, living in trillions throughout the human gut—more than stars in the observable universe.

•
Healthy Microbiomes Maintain Diverse Phage Populations14:42
Healthy guts have abundant and diverse phage populations that unhealthy guts lose, suggesting phage diversity is a marker of microbiome health.
