What does the body of evidence say on microplastics and their impact on our health? Plus: we talk about what we have learned about long COVID since 2020, and we discuss the very first approval for a clinical application of the gene-editing technology known as CRISPR.   A Block: Microplastics (0:58) What are micro- and nanoplastics; microplastics in the environment and in our bodies; how they get into humans and animals; the infamous study that was retracted; occupational exposure to microplastics versus casual exposure; eating microplastics by consuming seafood; can they cause infertility; BPA and BPS; the latest study on microplastics; are plastic water filters bad; should you avoid bottled water; alternatives to single-use plastic bottles. B Block: Long COVID Update (37:55) The problems with diagnosing it; how to treat it; the involvement of the mitochondria; probiotics for long COVID; should people with long COVID exercise; the COVID vaccine protects against long COVID; direct-to-participant digitized clinical trials. C Block: CRISPR Therapy Approved (56:22) CRISPR therapy approved in the UK and US for sickle cell disease and transfusion-dependent beta thalassemia. Jonathan initially mischaracterizes the therapy as repairing the mutation. Chris corrects him.
