We’re talking about science. But not just any science...
Each episode, journalist Jo Marchant meets researchers who are doing things differently: challenging our assumptions, stretching our minds, and changing how we see the world.
We’ll be pushing boundaries from cosmology and quantum physics to neuroscience, archaeology, ecology… Jo’s guests are asking deep questions, chasing outrageous dreams, and exploring the world in completely new ways.
As well as learning about their pioneering ideas, we’ll hear their personal stories: what inspires their leaps of imagination; how they keep going despite the obstacles; the importance of thinking differently; and why we need creativity to survive. But most of all, Where The Wild Thoughts Are is about the wonder of peeking past supposed limits. Come into the wild with us, for a glimpse of what’s beyond…

In this first episode of Where the Wild Thoughts Are, I chat to Paco Calvo, prof of cognitive science from the University of Murcia in Spain. He’s author of the fascinating book Planta sapiens: Unmasking Plant Intelligence, and he researches the neurobiology of plants. From bean plants searching out supports to climb up, to parasitic vines chasing down prey, to slow-growing oak trees, Paco is convinced that not only are plants showing intelligent behaviour, they’re sentient, awake, aware.
Perhaps you’re convinced that of course plants aren’t thinking! But is that based on evidence? Could there be other routes to intelligence than the neurons we happen to find in our own brains?
Paco and I discuss how to tell if an organism is intelligent; some of plants’ most impressive abilities (my favourite is the chameleon vine); as well as the mechanics of botanical decision-making, including many of the same neurotransmitters found in animals.
And, of course, we talk about the ethical implications… What would it even mean to start considering our plant companions as sentient?

In the search for alien life, we don’t always hear much about the planet Venus. There’s a lot of effort going into detecting possible signs of life on Mars, and looking for potentially habitable planets beyond our solar system. But Venus seems a crazy place to look for aliens: its surface is burning hot, hot enough to melt lead; and it has clouds made of concentrated acid. But could a very different kind of life from ours be living in those cloud droplets?
My guest in this episode is astronomer Jane Greaves, from the University of Cardiff. A few years ago, she used a telescope in Hawaii to scan Venus’s clouds for a molecule called phosphine. On earth, phosphine is pretty rare, its only natural source is microbes in certain oxygen-starved environments. We don’t currently know of any way it could possibly be made on Venus, apart from life, but Jane figured why not just have a look anyway. And she found it…
Some findings immediately touch a nerve, and this was one of them. Researchers immediately criticised her work, attacking the team both scientifically and personally. But Jane and her colleagues have been working to gather more data and they’re building an ever-stronger picture that phosphine really is there in the clouds. That would mean either some really fascinating chemistry we’ve never thought of before – or potential life. And this just adds to a list of mysterious features on Venus, from strange particles in the clouds; to gases in amounts very different from what we’d expect; to something unexplained that is absorbing huge amounts of energy from the solar radiation hitting the planet...
Jand and I chat about her latest results, and what she thinks about the chances of life elsewhere, as well as the importance of going against the grain sometimes, to explore questions others might think are too crazy to even ask.

When physicists investigate the very smallest components of reality – atoms and subatomic particles – they famously find all sorts of things that make no sense. Particles can apparently be in different places at once, and they have different properties depending on how we measure them. Spooky effects seem to act instantaneously, across vast distances. The decisions we make can even alter journeys that particles have already made.
Researchers have come up with different interpretations for what these weird results might mean. Maybe mysterious waves we can’t measure are guiding the course of the entire universe. Or maybe there are countless parallel universes, hosting different versions of ourselves...
What if none of these ideas is wild enough? My guest in this episode, quantum physicist Chris Fuchs from the University of Massachusetts, thinks physicists are still being boxed in by their assumptions about reality. Chris has pioneered a new interpretation of quantum mechanics, called QBism, which says that the probabilities and predictions of quantum physics were never describing physical entities out there in the world. Instead, he says, they are telling us about… us.
QBism is seen by many physicists as extreme, but it’s also wild, lawless, freeing and I love it! Our tour of the QBist universe took us from starships and black holes to party games, gambling and free will. Enjoy.
