Gut bug transfer, Covid's effects on the brain

Science commentator Siouxsie Wiles looks at new research that's found transplanting gut bugs from old to young mice can counteract age-related changes in the brain, another survey that's found how IQ scores were affected by Covid infections and who's the most Covid-resistant of them all....people less open to new ideas, the extroverts and the narcissists, that's who. Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
