Hello, welcome to this week's naked scientists with me Chris Smith

and also with Helen Scales.

Hello Helen.

Now in this week's show how scientists have found a better way to conquer allergies

like hay fever, and that's using a short course of

injections so a piece of research not to be sniffed at also you've heard of music

for your ears music to your ears but what about music for your heart scientists have

found that certain types of music

can be better for you than others and will be hearing what they are and also

researchers have uncovered what controls the way that certain things taste and

you're not going to like it but under certain circumstances it's all down to the

bacteria that live in your mouth yum and on that tasty note Helen. Thanks Chris

also this week we're looking at how science is helping archaeologists to dig into the past.

We'll be hearing how scientists have found out a bit more

about what went on when stone henge was first built

and what the DNA of animals and crops is telling scientists

about how humans domesticated plants and livestock.

We'll also be delving into the fate of the people who made the Nazca lines.

Now these are huge markings carved into the desert in South America over a thousand years ago. But what happened

to the people who made them and then disappeared? Well scientists now have

uncovered some clues and will be finding out what they were and what they

thought went on a bit later on in the show.
