Bacteriology podcasts

Anna Truzzi and Luca Pellegrino discuss experiments on a historical antibacterial preparation and the sources of bias in AI systems. An external segment with Ian Scott and Ilaria Zanardi explores elephant communication, including low-frequency sound, long-distance signalling and the evidence for individually distinctive calls.

Hosted by Anna Truzzi, Luca Pellegrino

Vincent Racaniello, Kathy Spindler and Brianne Barker discuss research using generative AI to design complete bacteriophage genomes, including reported viable phages active against antibiotic-resistant bacteria. They also examine a study linking recombinant shingles vaccination with lower cardiovascular-event risk. The discussion connects genome modelling, experimental virology and vaccine research, alongside listener letters and weekly selections.

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.

Hosted by Vincent Racaniello, Michael Schmidt

Nature's podcast explores genetically engineered probiotic bacteria that sense elevated glucose and release therapeutic factors, lowering blood sugar in animal studies. The episode also covers ecological research on pumas, geological erosion, and how a solar eclipse can help researchers probe the Sun's magnetic corona.

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.

Melissa and Jam examine wool, lanolin and claims about resistance to odour and bacteria. The episode connects their chemical structures with water-repelling behaviour, processing and interactions with microbes, distinguishing observed odour reduction from broader claims about antimicrobial activity.

Markus Covert discusses comprehensive bacterial cell simulations and what whole-cell modelling could contribute to future studies of neurons.

Lars Bakken discusses using bacteria to reduce nitrous-oxide emissions associated with agricultural fertilizer. Conversation in Norwegian.

Jessica Lønn-Stensrud discusses bacteria, their roles in everyday life and the balance between beneficial and harmful microorganisms. Conversation in Norwegian.
