Spark

In honour of World Radio Day, we explore the magic behind one of the most important technological creations in history, the innovations it inspired and its enduring power in an increasingly digitized world.

Imagination is often dismissed as childish, or a frill. But it also lets us picture alternative futures, and technologies that haven't been invented yet. So how do we harness our imagination? And in an age where Big Tech promises to solve our problems for us, how do we use our imaginations to build the futures we want?

In a world where our digital tools keep an accurate record of handy facts and events, what is our fragile, fallible human memory good for?

The competition in sports equipment is heating up — with everything from high-tech "super shoes" for marathoners to "smart blades" for ice skating. Beyond the hype, how much difference can these innovations make to you and me?

Sure, the tech we use every day is littered with disinformation, bad behaviour and privacy violations…but it's not all bad news! To mark the 600th episode of Spark, we look at the surprising reasons to be optimistic in 2024 — from quantum computing to learning from video games.

Is it possible to control our compulsive—and reflexive—use of our digital tech so we can savour the space for rest, relaxation and restoration? We offer a start of the year check up, exploring tech overuse and how to restore some balance to our busy, digital lives.

The feeling of belonging is a core, human drive. And feeling excluded is painful. But has our desire to belong—and how we try to achieve that—changed in digital culture?

DNA-based technologies are increasingly used for real world, high impact purposes—from tracking biodiversity, to designing crops for climate change, to treating debilitating diseases. How do we democratize the availability while mitigating the risk?
