A podcast at the crossroads of microbiology, immunology, evolution, computational biology and more. Through informal interviews with researchers and students, I explore how biological organisms are "holobionts": super-organisms formed by a host and all of its communities of micro-organisms ( bacteria, viruses, fungi...)

    #22 Can (and should) we patent DNA ? (Jorge L. Contreras)

    Jorge L. Contreras is a Professor of Law at the University of Utah, specialising in Intellectual Property and Technology Law. He is the author of 150+ scholarly publications, alongside praised non-fiction books including “The Genome Defense: Inside the Epic Legal Battle to determine who owns your DNA” (2021). This book explores the AMP vs Myriad Case, which was sparked by patents litigations on the breast cancer gene BRCA for diagnostics, and historically determined that naturally occuring genes cannot be patented.

    #21 The Tangled Story of H.pylori (Barry Marshall)

    #21 The Tangled Story of H.pylori (Barry Marshall)

    Barry Marshall is a Professor of Clinical Microbiology at the University of Western Australia. Alongside Robin Warren, he received the Nobel Prize in Physiology or Medicine in 2005 for first showing that Helicobacter pylori bacteria, rather than acid, were the cause of stomach ulcers. For this, Marshall did a self-experiment where he ingested H.pylori and gave himself acute gastritis, establishing a first link between the infectious agent and the development of gastric disorders. 

    We also embark on (a few) tangents:

    [11:10]  Self-experiment ingesting H.pylori

    #20 Philosophy of Immunology and the Biological Self (Thomas Pradeu)

    Thomas Pradeu is a CNRS Research Director in Philosophy of Science, leading a group at the ImmunoConcept called Conceptual Biology and Medicine. His group explores conceptual aspects spanning immunology, evolutionary biology, ageing and the microbiome. 

    We discuss:


    What Philosophy of Immunology is 
    How to assess the influence of an idea
    Misconceptions about the immune system
    The usefulness of the self/non-self framework
    Definitions of cancer in multicellular organisms
    How to integrate philosophy in science

    #19 Stochastic Models of Evolution (Amaury Lambert)

    Prof Amaury Lambert is a mathematician, leading a research group called SMILE (Stochastic Models for Inference of Life Evolution) at the Collège de France in Paris. He is also a Professor at the Ecole Normale Superieure in Paris. 



    In this conversation, we discuss


    Mathematical definition of species
    Modelling the birth and death of species
    Using DNA sequences to infer common ancestors and species history
    Contingency in evolution
    Beauty in mathematics vs biology

    #18 Tracking Emerging Viruses (Miles Carroll)

    Miles Carroll is leading a research group on High Consequence Emerging Viruses at the University of Oxford, and has previously worked at Oxford Biomedica and as head of research at Public Health England (PHE).

    This episode focuses on emerging viruses, which are viruses like coronaviruses and Ebola virus that have rising incidence or are increasing in distribution. We discuss:


    What makes an emerging virus successful
    Fieldwork during the West African Ebola outbreak (2013-2016)
    Using Nanopore sequencing and molecular epidemiology to track emerging viruses
    How to deal with the threat of future spillover events

    #17 Bacteriophage Therapy against Cholera (Minmin Yen)

    #17 Bacteriophage Therapy against Cholera (Minmin Yen)

    Dr Minmin Yen (PhD) is the co-founder and CEO of PhagePro, an early stage bio-tech company spun out of the Camilli lab at Tufts University developing bacteriophage prophylactics against cholera, a diarrhoeal disease caused by Vibrio cholerae. Minimin Yen has been recognised by the MIT's Tech Review as 35 innovators under 35 for her work bridging biological engineering and public health. 

    In this conversation we discuss:


    The evidence that bacteriophages play a role in cholera epidemics
    The strategy of delivering lytic bacteriophages to prevent person-person transmission
    How we can compound the emergence of resistance in cholera bacteria
    Building trust in communities for adoption of experimental therapies
    The challenges of developing a biotech and manufacturing bacteriophage prophylactics
