Stripping down science, the naked scientists.

Hello, welcome to this week's naked scientists with Helen Scales.

Hi Helen, hi Helen, and with me Chris Smith.

Now this week coming up is a new way to rewrite

road markings just by pressing a button. Also we'll be finding out how

researchers have come up with a strategy to make sure that you execute the perfect penalty shootout

and also how scientists have solved a 100-year-old mystery by identifying strange

infection strange infectious crystals that appear inside the cells of insects and they make them change color.

Helen. And also this week we are unraveling the mystery of mummies and other ancient archaeological

discoveries that have been dug up in Peru by London University's Lawrence Owens

brace yourself because we'll be hearing some gruesome stories of diseases stillbirths

and abuse but on a lighter note Durham University's Keith Dobley will be explaining where all of our domestic animals come from, including man's best friend, the humble pooch.

First up this week, scientists have cracked a rather interesting puzzle which is it's rush hour.

You've got lots of cars on the road and they're fighting for space.

How do we make the roads more efficient places for cars to be so that we can rewrite road markings in such a way that we can make most use of the road?

Well, wouldn't it be really good rather than having to put loads of signs and barriers and that kind of things,

if you could just click a mouse button and the road markings would change so that some lanes would become one direction

and some lanes another. Well that's what's on the mind of electricity and engineering giant Phillips because

they filed a patent this week for these literally re-writeable road markings.

Now here's how it works, very clever.
