The Hello, welcome to the naked scientist with me Chris Smith and also with Catani.

This week we're peeling away at plastics which are seemingly everywhere in

modern-day life but what exactly is a plastic? How is it affecting the fish in the

ocean and us here on dry land? Plus we look at whether the stats on recycling really are rubbish

and is recycling plastic worth the effort.

And look into the future, could farmers one day be growing plastic in their fields?

Also in the news this week how scientists are... farmers one day be growing plastic in their fields?

Also in the news this week how scientists have found a way to read the

burned Roman scrolls buried by the eruption of Asuvius 2,000 years ago.

We tour a new exhibition which explores the scientific legacy of Winston Churchill 50 years after he died,

and how scientists are reading the magnetic signatures of meteorites to find out how they and our planet formed 4.5 billion years ago.

Roman Scruels, burned and buried 2,000 years ago when Mount Vesuvius erupted are being read successfully

by Italian scientists using a new technique

that uses one of the brightest lights in the universe, an X-ray synchrotron beam

based in Grenoble, France. Science reporter Jonathan Webb has been taking a look at the story.

These were dug up a couple of centuries ago from Herculaneum, which is sometimes called the

other Pompeii. It's a village that was similarly buried by the eruption of Mount Vesuvius in about 79 AD,

but these scrolls are actually the only surviving library from those classical times.

The tricky thing is working out what's inside them because as soon as you try and

unroll them, they start to fall apart.

And there were various attempts to try and unroll them to varying degrees over the centuries,
