In this week's episode of Science Weekly, Madeleine Finlay is joined by co-host and Guardian science editor Ian Sample to discuss three notable science stories.
Sex differences from birth
The first story concerns a study that offers a clue in the long-standing debate over whether sex differences are present from birth or are a product of socialisation. The findings provide new insight into this age-old question.
Super El Niño forecast
The discussion also covers the super El Niño, which is predicted to lead to 450,000 deaths in the next six months. This significant climate event has major implications for global health.
UK meningitis outbreak
Finally, the episode addresses why the UK's meningitis outbreak earlier this year was so large, providing an explanation for the scale of the outbreak.
