Unexpected Elements is all about finding the surprising science angles to everyday news.
Mind absolutely blown.
Amazing.
To me, that's Unexpected Elements from the BBC World Service.

Welcome to the World Book Club podcast.
I'm Harriet Gilbert and this month we've been reading a rather unusual love story, an internationally best selling novel called the Time Traveller's Wife.
And joining us to answer questions about it from BBC listeners around the world is its American author, Audrey Niffenegger.
Audrey, welcome to BBC World Book Club.
Thank you so much.
Am I right in saying that you began your working life actually not as a writer, but as an artist?
Yes, and I'm still a practicing artist.
I was making artists books and so I was writing and making images and at some point I had an idea that I thought, oh, this involves moving time around in a way that still images aren't really going to suffice for, and perhaps it should be a film.
And I thought, no, I don't have any money, I can't make a film.
And I thought, I'll write a novel.
Well, Indeed.
Of Audrey's 15 or so books, eight are either artists books or graphic novels.
But it was her first purely verbal novel, the Time Traveller's Wife, that earned her international fame.
Translated into 44 languages to date, it's sold more than 8 million copies and been adapted for the cinema, for TV, even for the stage.
I've described it as a love story, and it is.
