I have you loud and clear.

Hello.

Hello.

Welcome.

Science and that is the same physics medicine nature or space time brain life the universe

This week we're taking a spin around the electron how does a fridge magnet stay stuck and how can quantum physics

help us in battling cancer? We'll be finding out. Plus in the news the chemistry

of breaking down microplastics exploring bacterial infections resistant to last line antibiotics,

and we're going back to school for you lessons.

I'm Isie Clark.

I'm Katie Haler and this is the Naked Scientists.

The Naked Scientists podcast is powered by UKfast.co. Hearts. Researchers from Carnegie Mellon University have developed

a way of 3D printing components of the human heart, which could be beneficial

considering there are around 7.4 million people in the UK with heart and

circulatory disease. The parts are made of collagen, the main structural protein in our bodies, and they work just like real heart tissue.

Printing collagen has been a major hurdle in biomedical engineering, but now the team has made a big leap forward.

Andrew Hudson, one of the lead authors on this paper, spoke to Phil Sansom.

A group of biomedical engineers at Carnegie Mellon University have been working on something amazing,

3D printed bits of human heart.

It's all thanks to their special 3D printing technique called Fresh.

Fresh stands for free form reversible embedding of suspended hydrogels, and this is a technique
