Falling fertility: lessons learned from Botswana
2018-10-25 22:00:07

The weight is over: will kilograms get an upgrade?
2018-10-05 04:30:33
On 16 November, scientists vote on whether to update the way we measure the kilogram. This week, Ian Sample investigates the history of the metric system, and finds out how universal constants might now make it more robust

Opioid addiction: can the UK curb the looming crisis?
2018-09-20 22:00:17
The US has been in the grip of an 'opioid epidemic' since the 1990s, and now a rise in opioid prescriptions and deaths is being seen across the pond. Ian Sample investigates and asks: what can we do the curb the looming crisis?


Are fungi the secret to a sweet sounding violin?
2018-09-13 22:00:15
From making violins sound beautiful, to beer and bread, to creating life-saving medicine, fungi have an array of very useful attributes. This week, a report demonstrates just how little we know about this kingdom of life and what we are set to gain if we tap into fungi as a resource. Hannah Devlin investigates.

Now Playing: TED Radio Hour

Circular
We're told if the economy is growing, and if we keep producing, that's a good thing. But at what cost? This hour, TED speakers explore circular systems that regenerate and re-use what we already have. Guests include economist Kate Raworth, environmental activist Tristram Stuart, landscape architect Kate Orff, entrepreneur David Katz, and graphic designer Jessi Arrington.

#504 The Art of Logic
How can mathematics help us have better arguments? This week we spend the hour with "The Art of Logic in an Illogical World" author, mathematician Eugenia Cheng, as she makes her case that the logic of mathematics can combine with emotional resonance to allow us to have better debates and arguments. Along the way we learn a lot about rigorous logic using arguments you're probably having every day, while also learning a lot about our own underlying beliefs and assumptions.
