Love is in the air(waves) as Brian and Robin trawl through the Monkey Cage archive. From using maths to find a boyfriend or girlfriend, to why birds and bees have far more exciting sex lives than you might imagine, this week’s episode is all about passion.

Number crunching might not sound sexy but mathematician Hannah Fry tells Robin Ince and Brian Cox why research shows it pays to be proactive when you’re searching for a partner, even when that means risking total humiliation. But when it comes to the world's most extraordinary mating rituals the best place to look is… in the garden. Female bees go on a special nuptial flight, where they’re impregnated by males mid-air, and we hear how cockerels are surprisingly picky when it comes to which chicken they choose to cosy up with.

New episodes will be released on Wednesdays. If you’re in the UK, listen to the full series on BBC Sounds: bbc.in/3K3JzyF
