Where The Wild Thoughts Are
Podcast Description
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… Hosted on Acast.

This week, we’re digging into how living creatures – including us – sense and respond to magnetic fields with quantum biologist Margaret Ahmad of the University of Sorbonne in Paris.
For decades, biologists knew about striking examples of species apparently navigating by Earth’s magnetic field, from monarch butterflies to loggerhead turtles to racing pigeons. Yet for years, many physicists said any ‘magnetosense’ was impossible, insisting the Earth’s field is far too weak to affect any biological processes within living cells. And yet, life really had found a way, and Margaret was one of the key researchers who showed how.
Back in the 1990s, she discovered a blue light receptor in plants, part of a mysterious family of proteins called cryptochromes, and she has since has pioneered research showing how these receptors don’t just sense light but magnetic fields, too. Through quantum physical effects, these proteins magnify impossibly weak magnetic signals into measurable biological responses in a cell.
For Margaret, this connection with the magnetic fields around us is a fundamental characteristic of all life, that should transform our thinking about everything from bird migration, to plant growth, to health effects in humans – and might even lead to revolutionary medical treatments. I spoke to her about her research, what it’s like doing science ‘out on a limb’, as she puts it, and what to do when the evidence leads you off the beaten track…

Some bacteria sense magnetic fields via magnetite crystals. It’s possible these play a role in other species too, maybe even humans
