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.
