Welcome to The World, the Universe and Us, a weekly news podcast from New Scientist.
I'm Rowan Hooper.
But you're not Penny Sarche.
No, I'm Sam Wong.
On today's show, we talk with a professor of tectonics about the recent Russian earthquake,
which is the sixth biggest quake ever recorded.
And we have the startling news that a bacterium has been created with more than 100,000 changes to its genome.
So we can almost say we've created a life form.
Almost, but not quite.
But it's definitely the most unnatural thing we've ever created.
And that's coming up.
But we're going to start with the equally exciting news that the weight loss drugs Ozempic and Wegovi,
they slow down biological ageing.
Now, we've all heard of Ozempic and Wegovi.
They use a hormone mimic called semaglutide to dramatically help people lose weight.
And it's been... extraordinary how the use of these drugs has taken off over the last few years.
It's transformative.
I think I've said on the podcast before,
I can't think of another drug that's had quite as big an impact as those.
