In the Spotlight this week, we revisit a recurring theme to explore whether a paper claiming no advantage for males who identify as women has any validity, and we cover some news from the world of sport and health.

17:31 Our main focus is on a systematic review, published last week, claiming that evidence suggests no physical differences and thus no sporting advantages in trans identified males. We explain why the paper is misleading, and how the authors and journal ignored very obvious flaws in the research to arrive at their conclusion.

1:31 We also discuss an interview given by Imane Khelif in which the Algerian boxer confirms what was already widely known about male advantage, as well as some surprising details about suppressing testosterone, and defiance and denial about male advantage.

36:44 In sports action, Femke Bol made an 800m debut indoors - we discuss the performance and what it tells us of her ceiling.

43:20 Serena Williams is making a return, but appeared in a Superbowl halftime advertisement to promote ozempic for weight loss, which triggered a wave of criticism and fear about the displacement of exercise, diet and responsibillty for weight loss. We consider the arguments.

50:52 Continuous glucose monitors are in the spotlight, after a range were recalled for providing inaccurate data, which has lead to death and injury in people misled by dodgy data. We discuss the matter in the context of how wearables have to, at a minimum, provide accurate information when decision making will change on the basis of that information.

And finally, a Lance Armstrong movie is imminent, and Hollie Davidson referees a Six Nations match at the weekend. We end with brief thoughts.
