Dual-Sex Butterfly and the Risks of ... Oxygen

The video discusses two main topics: the discovery of a rare bilateral gynandromorph butterfly at Britain's Drexel University, and a study linking oxygen levels at different elevations to cancer risk. The butterfly, with male and female characteristics on opposite sides, highlights a rare genetic condition. The study suggests that higher oxygen intake at lower elevations may increase lung cancer risk due to reactive oxygen species, though it does not establish causation.

What are reactive oxygen species and how can they affect human health?

What precautions should one take based on the findings of the study regarding oxygen levels and cancer?
