Vagus Nerve Memory, Cat Cancer Genes, Inherited Intelligence, Mulberry Microbes, and Vitamin D : 1548

Host Dave Asprey examines new research on vagus nerve stimulation for cognitive impairment, genetic similarities between cat and human cancers, a twin study on inherited intelligence, mulberry compounds and the gut microbiome, and the complex relationship between magnesium and vitamin D metabolism. The episode separates promising biological mechanisms from proven interventions, cautioning listeners not to extrapolate lab findings to consumer products or health claims. Several studies discussed predate this week’s coverage; this is a research roundup, not a list of newly published trials.
