A huge search is underway for the killer of the influential conservative US activist and ally of President Trump, Charlie Kirk. We hear from our correspondent at the university campus in Utah where the shooting happened. Also: Britain's prime minister has sacked the UK ambassador to Washington, Peter Mandelson, over his ties to the late convicted paedophile, Jeffery Epstein; a BBC investigation has revealed the scale of an international charity’s involvement in the systematic disappearance of children during former Syrian President Bashar al-Assad's regime, and the dark DNA that could explain the extraordinary dancing peacock spider.

In an extended version of the programme that was broadcast, Melvyn Bragg and guests discuss the influential book John Maynard Keynes wrote in 1919 after he resigned in protest from his role at the Paris Peace Conference. There the victors of World War One were deciding the fate of the defeated, especially Germany and Austria-Hungary, and Keynes wanted the world to know his view that the economic consequences would be disastrous for all. Soon Germany used his book to support their claim that the Treaty was grossly unfair, a sentiment that fed into British appeasement in the 1930s and has since prompted debate over whether Keynes had only warned of disaster or somehow contributed to it.

Spanning history, religion, culture, science and philosophy, In Our Time from BBC Radio 4 is essential listening for the intellectually curious. In each episode, host Melvyn Bragg and expert guests explore the characters, events and discoveries that have shaped our world.

One of Donald Trump's leading supporters -- the right-wing activist, Charlie Kirk -- has been shot dead. He was taking part in an outdoor debate at a university in Utah when he was hit by a single bullet. Video footage showed him slump in his seat on a stage in front of a large crowd at Utah Valley University in Orem. President Trump described him as legendary. He has ordered flags to be flown at half mast until Sunday. Also: Life on Mars? 'Leopard-spot' rocks could be biggest clue yet, and are you a hugger?

Rodrigo Medellin loves bats. The Mexican conservationist has been obsessed with the often maligned creatures for over six decades. As a child, he kept blood in ice cube trays in his parents' freezer, to feed to his pet vampire bats. He went on to create Mexico City’s first ever bat festival, and to work with governments, universities, NGOs and researchers all over the world. To many, Rodrigo IS the "bat man."

Like many Mexicans, he is also fiercely proud of the country’s native spirits: tequila and mezcal. The agave spirits are hugely important for Mexico’s economy, especially in the states of Jalisco and Oaxaca. Exports of the drinks are worth billions. Tequila and mezcal have become increasingly popular in recent decades, with sales boosted by big budget celebrity-owned brands designed to appeal to the US consumer. From Kendall Jenner to George Clooney, US celebrities have been riding high on the mass market appeal of the liquor.

But the boom in these industries has had unintended consequences for Rodrigo's beloved bats. Often the agave the spirits are made from is harvested early, before the slow-growing plant can flower. This means bats cannot feed from the nectar, and critically, they can’t do their job as pollinators. This contributes to agave monocultures which are susceptible to disease and blight.

Rodrigo explains how he wanted to change the way the industry works, creating a “bat-friendly” certification for tequila and mezcal producers who leave 5% of the agave untouched, to bloom. But why have so few brands been certified, why is the programme controversial for some producers, and why are bats a tricky sell as far as conservation for many people and communities? Sarah Treanor spends time with Rodrigo in Mexico City and Oaxaca to find out.
