Science Weekly · Can a world-first gene therapy reverse ageing? · 16 Jul 2026 podcast

Totally. matched

And let me give you a bit of context. matched

I mean, over the past decade or so, we've seen a really dramatic increase in longevity research. matched

And look, a lot of this is funded by very wealthy individuals, but much of it is based on really interesting advances in biology. matched

And what it's led to is this huge effort to build, often drugs, that will slow or reverse ageing. matched

What this trial is all about is this really radical idea, extremely interesting idea of being able to rejuvenate cells and actually rewind the clock on cells and make adult, old cells work like young ones. matched

So obviously, as we age, as our cells get older, they become less good at doing all those functions that they need to do to keep us healthy. matched

And there's a whole bunch of processes that drive this, right? matched

But things like, you know, your... matched

Your DNA accumulates damage over time because the way cells repair DNA isn't perfect. matched

The mitochondria, which are these sort of the power plants in our cells that give them energy, those become less efficient. matched

What's most important for this study is something else. matched
