Signals, seaweed and space

BBC World Service - Unexpected Elements, Signals, seaweed and space

The anniversary of the telegraph sparks an unexpected conversation about bioelectricity.

On the anniversary of the first telegraph being sent, the team discover how the telegraph was used as a colonial tool in Ghana, and how an eccentric Brazilian emperor helped spark a communications revolution.

They also reveal how tiny worms have helped scientists work out how our hearing works, and how bioelectricity might help focus your mind and heal your wounds.

There’s a tale of evil seaweed causing havoc for coastal communities, a scientist studying misophonia makes a pitch for The Coolest Science in the World, and there’s a listener question about how chickens fly.

And Marnie delves into a lesser known history of space flight, with the tale of a Zambian man who dreamt of being an astronaut.
