  • Episode 11 – Gut Microbiota
    This week’s episode discusses all those microbes living in your intestine — the gut microbiota! How can all these bacteria effect your behaviour? Listen here…   Here are a couple links to the papers I mention in this episode: 1. Gut/brain axis and the microbiota 2. Gut microbiome and depression: what we know and what … Continue reading "Episode 11 – Gut Microbiota"

  • Episode 10 – The New Cash Crop


    This week’s episode talks about the newly legalized (in Canada) Cannabis. Coming from a biological point of view, what work can be, or has been done with the Cannabis plant in order to improve crop performance and yield?

    Here are a couple links to the work done at the University of Guelph:

    Optimal Rate of Organic Fertilizer during the Flowering Stage for Cannabis Grown in Two Coir-based Substrates

    Vegetative propagation of cannabis by stem cuttings: effects of leaf number, cutting position, rooting hormone, and leaf tip removal

    This site gives a really good run down on the different terpenes, and how they could affect your experience: Leafly

  • Episode 9 -rBST in Dairy

    In Canada, this is the logo you’re looking for if you want to steer clear of rBST milk products.

    This week’s episode discusses how the new USMCA agreement affects the dairy market, specifically in regards to the use of rBST in cattle.

    Here’s the link to the meta-analysis I discuss:

    A meta-analysis review of the effects of recombinant bovine somatotropin 2. Effects on animal health, reproductive performance, and culling

  • Episode 8 – CRISPR Pt. 2

    Back at you with part two of the CRISPR discussion! On this episode I go through three recently published articles showing some of the applications of the CRISPR-Cas9 gene editing system.

    https://ia601504.us.archive.org/30/items/WABCRISPRPt2/WABCRISPRPt2.mp3

    Here are links to the three papers I discuss:

    1. Muscle-specific CRISPR/Cas9 dystrophin gene editing ameliorates pathophysiology in a mouse model for Duchenne muscular dystrophy
    2. Inactivation of porcine endogenous retrovirus in pigs using CRISPR-Cas9
    3. Development of broad virus resistance in non‐transgenic cucumber using CRISPR/Cas9 technology

  • Episode 7 – CRISPR Pt. 1

    This week you get part 1 of a two part podcast on CRISPR-Cas technology. In this first part I’m talking about what it is and how it works. Next episode I’ll go though some recent research articles using the CRISPR-Cas system!

    https://ia601502.us.archive.org/6/items/WABEpisode7/WABEpisode7.mp3

    A visual representation of how the CRISPR-Cas system works to combat a viral infection.

  • Episode 6 – Blood Types

    In this week’s episode I’m talking about blood types, and a technique that could be used to develop universal blood:

    https://ia601505.us.archive.org/5/items/WABEpisode6/WABEpisode6.mp3

    Here’s a good visual representation of the red blood cells of different ABO blood types, and the antibodies present in plasma associated with these types.

    This image allows you to visualize the sugar structures on the different blood type red blood cells. Each hexagon represents a different sugar type. Note how to A, B, and AB red blood cells have additional sugars that the O red blood cells do not. These are the desired targets of the enzymes. 

    As promised here’s the link to the abstract I discuss:

    Discovery of CAZYmes for cell surface glycan removal through metagenomics: Towards universal blood

    And here is an additional paper by the same group:

    oward Efficient Enzymes for the Generation of Universal Blood through Structure-Guided Directed Evolution

Each week I'll be discussing a different current biological research topic, explaining how it applies to the real world. There's so much research going on, but so little of it makes it to the general public -- I'm here to change this. Blog: wordsaboutbiology.wordpress.com
