In this week's episode of the Beta Sandwich Science Podcast Scott and the team discuss how we may be at a tipping point with gene therapy and what that means for you. In 'Science Blast' we discuss: how micromotors are being used to clean polluted water using platinum and iron; how the diversity of your gut bacteria is affected by the food you eat; and how low folate ( vitamin B9) has been linked to birth defects in mice. In 'The Meat of the Sandwich' Scott covers Gene Therapy. The government is being asked to lift restriction as the efficacy and reliability of gene therapy increases. Will you one day just get a shot to cure you of Alzheimer’s or other ailments?
