Science commentator Siouxsie Wiles joins Kathryn to look at the new studies into long Covid, including one that found patients could take up to a month to return to normal sleep and exercise patterns, and another that found poorer people are less likely to be tested for Covid and more likely to be hospitalised, enter ICU and die. She'll also look at how the tell-tale signs of a stroke may appear up to 10 years beforehand and how whale sharks can be tracked, just by testing water.
Associate Professor Dr Siouxsie Wiles is the head of Bioluminescent Superbugs Lab at the University of Auckland.
