The Problems With Scheduled Power Outages

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 load shedding – why is their power being switched off and is there a light at the end of the tunnel? We continue our quest to find The Coolest Science in the World with a man using tiny microbes for big problems, and the launch of a new BBC World Service drama about Fukushima gets us thinking about the consequences.

All that plus your emails and whatsapps, a team in three different countries and the decadence of Marnie’s footwear choices.
