Thought that this might be of interest. Margaret ps Trying to attach page again. Fingers crossed! pps back to the drawing board - will try again. Still no success but if you are interested look on the BBC web page: news.bbc.co.uk in the "UK" section and then the "England" section. Sorry. Hope that I have not totally confused everyone. M
Here's the link from the Guardian: http://www.guardian.co.uk/science/story/0,,1876414,00.html (Margaret, links are handled differently from attachments - you can just cut and paste the URL (the part that starts with http:// ) into the message body)
