It's science, but not as you know it. The Naked Scientists.

Hello, robot helping to clear minefields much more quickly.

Also, raindrops on roses, I won't sing anymore,

but scientists have discovered why dewdrops cling on to rose petals,

though they look pretty.

And also, it's on the tip of my tongue.

We've all had that experience of not being able to find the word we want, but why does it happen and how can you stop it?

More's the point. That's all on the way, Helen.

Thanks, Chris. Also this week we're looking at the science behind the sparkle because we're delving into diamonds

and other precious stones to find out how they form, how they can be faked, how to spot a dodgy diamond

and how they can be used to make high-powered lasers, cutting-edge scalples, ha ha, and even superior sounding

speakers for your hi-fi.

So that's all on the way.

Plus in Question of the Week, we'll be drilling for the answer to this.

During the 1970s we were told that oil would run out by the year 2000.

Then new reserves were discovered and now they say 2,100 is when we will be starved of oil.

Is it possible that we'll find more oil reserves in time to come?

And obviously the answer to that question doesn't apply if you live in Grange mouth in Scotland.

That could be a bit different under those circumstances.

Thank you, Helen.

So if you've got any questions for us about the science of diamonds or

other geological marvels, then do get in touch.
