The Guardian’s science editor, Ian Sample, talks to Madeleine Finlay about three eye-catching science stories from the week, including a study that explores the link between exercise and brain health. Also on the agenda: the discovery that hedgehogs can hear high-frequency ultrasound and what this could mean for their conservation, and new research examining how biased AI autocomplete tools can influence the beliefs of users.
