This week on the show that brings you the science behind the news, there are lots of stories about inflation in economies across the world. When inflation happens your money doesn’t go as far, so what does psychology say about how much money you really need to make you happy? We humans aren’t the only ones experiencing inflation either, trees are suffering from it too. We find out what happens when the balance of supply and demand of nutrients between trees and fungi is disrupted by climate change. And then we take a look at the bigger picture - the much bigger picture - as cosmologist Ghazal Geshnizjani tells us about how the entire universe once existed in a space smaller than a marble. Plus, are Romanian bear populations inflating? We probe a scientist about spider webs – why do they look the way they do? And we look at vaping – it’s illegal in some countries while smokers in other countries are encouraged to take it up. All that plus your emails, WhatsApps and some unexpected elephants. Presenter: Caroline Steel, with Godfred Boafo and Andrada Fiscutean. Produced by Ben Motley, with Alex Mansfield, Sophie Ormiston and Margaret Sessa Hawkins.

How does our brain process language? We speak to an expert who is using technology to turn narrative thoughts into text. Also on the show, what is happening in our brains when we switch languages? And what are the positives and perils of technology and translation? Also on the show, we look at internet connectivity in incredibly remote areas, whether carbon capture is realistic, and we continue to explore different foods from around the world.

In a week where global heat records have melted, we find out how that can make fish life-threateningly stupid. We also dive a little deeper to find the part of the ocean where a little heat proves life-enhancing. And we bring you boring science… no, not in that way. Find out what tree rings can tell us about ancient civilizations and past climates. Also, a new Japanese mission aims to park nice and neatly on the moon – how different is that from the famous first effort from the Apollo 11 team? We hear about an unwelcome Delhi resident that’s taking years off locals lives – air pollution. And what is a “supervolcano” and how likely is it that one ruins our run as dominant species on this planet? Presented by Marnie Chesterton With Chhavi Sachdev and Tristan Ahtone Producers: Alex Mansfield, Ben Motley, Sophie Ormiston, Emily Bird and Patrick Hughes

Following recent coups in Niger and Gabon, and with seven African coups in the last three years, some political commentators are suggesting that there might be an epidemic of coups. But are coups really contagious, and what does the political science say? Caroline Steel and the Unexpected Elements team across three different continents go on a quest to find the science lurking behind the news. We find out what trees in Chile can tell us about coups and we meet the wasp that performs a coup on a poor unsuspecting cockroach, turning it into a zombie and eating it alive. There’s light relief in the form of cows listening to classical music, the answer to a listener question about carbon capture and reflections on efforts to rid the world of plastic bags. All that plus your emails, whatsapps, and more fruit chat than you can shake a banana skin at. Presented by Caroline Steel Produced by Ben Motley, with Margaret Sessa Hawkins and Sophie Ormiston

India's successful moon landing has the Unexpected Elements team engaging in some serious lunacy. We look at where the moon even came from, how it helps us navigate, and whether it has a cultural and ecological heritage. Also on the show, is Dr. TikTok leading to a raft of self-diagnoses, should we be eating banana peels and worms, and we go back to the moon to see if it has any effect on our sleep.
