Digital technology has transformed the science of bioacoustics - the ways we hear and record animal life in the deep oceans, through the earth and in the skies. Vast leaps in computing power allow us to analyse hundreds of thousands of hours of chirps, whistles, clicks and rumbles. Some researchers say AI can help us understand how elephants communicate in the jungle, what whales are clicking to one another across the watery abyss, and what bats squeal when swooping through the sky. Can we, should we, become digital Dolittles? Maria Margaronis listens in to these ever-expanding realms and wonders what they tell us about our own place on the planet.

Our bodies are filled with bacteria that have rich social lives and, just like people, these microbial neighbours and families do not always get along. In some cases, it is the bacterial equivalent of The Sopranos. Dr Sally Le Page delves into the bacterial dramas of loners, crowd-lovers, backstabbers and do-gooders that are fighting it out in the world and inside our bodies. Co-operation, cheating and selfish behaviour can all lead to benefits or disease so scientists are studying this behaviour to help produce new medicines and clean up our environment.

Tens of thousands of Ukrainian army personnel have been killed since the Russian invasion of their country. Russian casualties could be as high as 250,000. But who rallies the troops when morale crumbles and fear creeps in? How important are religion and faith in the war effort? Lucy Ash hears from two military chaplains who live alongside troops on the Ukrainian side of the trenches. Forty-four-year-old Father Dmytro has lost some f his closest friends in the war and was himself injured in a Russian attack in 2022. But this has not shaken his faith. Lucy also hears from Sister Sasha who spends two weeks each month talking and listening to frontline soldiers. And she hears from Father Dmitry Vasilkenkov, head of the Russian military chaplains, about their role in the military. Most Russian clerics are too fearful to speak to foreign media, but one priest, opposed to the war, tells Lucy that some soldiers see faith and taking communion as “some kind of magic charm” offered to troops going into battle.
