As a human being, you are not a single organism but a thriving ecosystem home to trillions of invisible, living microbes. These microbial jungles within you and upon you are critical for your health and survival and may influence everything from your risk of cancer to your sexual attractiveness. In this podcast series (Biomes), Dr. Ruairi Robertson explores the fascinating new developments in our understanding of the human microbiome and talks to leading scientific experts around the world about the incredible ways microbes affect your body, from belly to brain. Season two of Biomes is sponsored by Microbiome Insights, a leading provider of microbiome sequencing and bioinformatics services (www.microbiomeinsights.com).

Vaginal Biomes | Prof. Doug Kwon | Season 3, Ep. 7
Tuesday Jul 16, 2024
Tuesday Jul 16, 2024
Some amazing evidence now shows that the vaginal microbiome can influence the risk of a woman giving birth prematurely and influence her risk of acquiring HIV or other sexually transmitted infections. This week, I speak with Prof. Doug Kwon all about this and about the evidence for probiotic or other microbiome therapies to improve women’s health.

Microbiome Myths | Profs Jens Walter and Alan Walker | Season 3, Ep. 6
Tuesday Jul 09, 2024
Tuesday Jul 09, 2024
Even though the microbiome field is very exciting, it is also unfortunately full of plenty of myths and hyperbole. It is important that we discuss these myths. In Episode 6, I speak to the two best Microbiome Myth Busters in the world, who take us through the inaccuracies that are prevalent in discourse about human microbiomes and why these can be detrimental for science and medicine.

CRISPR and gene editing biomes | Dr. Carlotta Ronda | Season 3, Ep. 5
Tuesday Jul 02, 2024
Tuesday Jul 02, 2024
Gene editing tools such as CRISPR are allowing scientists and medics to get rid of devastating genetic conditions, however they can also be used on microbes, meaning they could be used to alter the human microbiome. Dr. Carlotta Ronda is investigating how to gene edit microbiomes to benefit human and environmental health

Ultra-processed foods contain lots of additives to help with their shelf life. Emulsifiers are one type of additive included within many ultra-processed foods such as mayonnaise, chocolate, ice-cream etc. However, new research suggests that these emulsifiers may have a detrimental effect on the gut lining and the gut microbiome.

Breastmilk Biomes | Dr. Meghan Azad | Season 3, Ep. 3

Monday Jun 17, 2024
Humans can survive on human milk for at least the first 6 months of life yet surprisingly little has been researcher about this human superfood. Human milk contains prebiotic sugars, antibodies and live microbes, all of which can influence the gut microbiome of babies. I speak with Dr. Meghan Azad from the University of Manitoba about her research on human milk and the infant gut microbiome.

Increasingly, dietary sugar is being replaced by non-caloric sweeteners in our diets. But what effects do these sweeteners have on our health? Only last year, the World Health Organisation categorized the sweetener aspartame as "possibly carcinogenic to humans", yet lots of evidence suggest that sweeteners are beneficial for weight loss and blood sugar control if they replace high sugar intakes. In this episode, I speak with Dr. Jotham Suez who has conducted some ground-breaking research on the effect of non-caloric sweeteners on the gut microbiome and the potential detrimental effects this may have on metabolic health.

Season 2, Ep. 6: Infection Biomes | Prof. Brett Finlay
Wednesday Mar 03, 2021
Wednesday Mar 03, 2021
Infectious diseases have largely been replaced by chronic diseases such as diabetes, heart disease and cancer in the Western world. However, the COVID-19 pandemic has shown us that humans are still at significant risk from microbial-diseases. In this episode, Dr. Ruairi Robertson speaks with Prof. Brett Finlay from University of British Columbia, one of the world’s leading experts on infectious diseases. Prof. Finlay discusses his career studying infectious microbes and how this led him to shift focus to all of the other microbes in our body. He discusses the influence of the gut microbiome on infection susceptibility, fulfilling Koch’s postulates for the gut microbiome and the influence of early life gut microbes on ‘modern plagues’ such as asthma and allergies.
Prof. Finlay is one of the scientific co-founders of Microbiome Insights along with Dr. Bill Mohn. Between them, they have published more than 600 peer reviewed papers and they provide key scientific guidance to the Microbiome Insights team. Find out more at www.microbiomeinsights.com.

Season 2, Ep. 5: Fungal Biomes | Prof. Marie Claire Arrieta

Wednesday Feb 24, 2021
When you hear the phrase ‘gut microbiome’, you most often think about bacteria. However, a huge proportion of your intestinal microbes are viruses, archaea and fungi. These other microbes however, have been studied in much less detail and we know less about what they are doing to your body. In this episode, Dr. Ruairi Robertson speaks with Dr. Marie Claire Arrietta from University of Calgary, a leading researcher on fungal microbiomes. She discusses how gut fungi interact with the immune system, myths about Candida and how gut fungi may affect children’s lung health.
Microbiome Insights provide services to assess the fungal microbiome using ITS2 sequencing. Find out more at www.microbiomeinsights.com

Season 2, Ep. 4: Cancer Biomes | Prof. Wendy Garrett
Wednesday Feb 17, 2021
Wednesday Feb 17, 2021
Colorectal cancer is one of the most common cancers and cancer deaths worldwide and its rates are increasing in many countries around the world, especially in younger adults. Emerging evidence points to a role of certain gut microbes in the progression of colorectal cancer by acting as toxins to gut cells. On the other hand, other microbes have been identified as potentially protective against colorectal cancer. In this episode of Biomes, Dr. Ruairi Robertson speaks with Prof. Wendy Garrett of Harvard University. Prof. Garrett is a leading doctor and researcher in the field of the colorectal cancer and the gut microbiome. Her work has shown exciting links between microbes originating in the mouth and how they may contribute to cancer when they travel down to the gut. Prof. Garrett discusses this research and future potential of targeting the gut microbiome as an adjunctive therapy for colorectal cancer.
