Unexpected Elements looks for the science behind the news, and this week the news is glittery and pink with the release of the Barbie movie. The movie has very pink aesthetic, so we get philosophical about the colour pink – does it actually exist and if so, how come it isn’t in the rainbow? We also discover how this iconic doll has performed some actual valuable science, helping cryogenic researchers design space suit technology to help future missions to the moon. In Ask the Unexpected this wee...

As French citizens protest against the raising of the state pension age, we look at the figures – are we really living longer? And if so, why? We take notes from the naked mole rat - it’s born looking wrinkled but this rodent is apparently ageless. And moving on from mere creatures, we’re asking if every state, society or civilisation has a lifespan, and if we can prevent it ending on our watch. Also, as South Africans battle to live their best lives against almost daily power cuts, we look at l...
