I have you loud and clear.

Hello.

Hello.

Welcome.

And that is the same.

physics, medicine, nature, space, time, brain, life, the universe.

This week, the discovery that's making waves

in the world of physics, gravitational waves, in fact, but what are gravitational waves and why are they set to change

how we see the universe in the future.

Plus we take a look at the week's leading science breakthroughs, including a way to see heart attacks

before they happen, fighting superbugs with door knobs, and is there such a thing as being

left or right brained? I'm Katani. And I'm Chris Smith and we're the

First this this week, heart disease. It's the commonest cause of death in the UK and it happens when the coronary arteries

that carry blood to the heart itself become furred up. Luckily nowadays doctors can reopen

narrowed arteries and prevent them from closing up again

by inserting metal cages called stents.

But knowing where to put the stent, in other, identifying the regions of the damaged blood vessels that are at

greatest risk of blocking and causing a heart attack can be very difficult.

Now help is at hand because Ramsey Camis, who's a British Heart Foundation cardiologist at Imperial College,
