Bacteriology podcasts

The hosts discuss research linking bacterial signatures to colon-cancer recurrence and a separate study of bacteriophage-derived proteins that trigger bacterial pilus detachment. The episode works through the scientific papers and experimental questions; the cancer findings concern an association rather than proof of causation.

Bonnie Bassler explains how bacteria detect signals from their surroundings and coordinate behaviour through quorum sensing. Chemical communication allows microbes to sense nearby populations and undertake collective activities that individual cells could not accomplish alone. The discussion examines bacterial information processing and the consequences of these coordinated behaviours, including within the human body.
