Who cannot marvel at the beauty of moss – nature’s carpet?
Since a teen I have been in wonder of moss – of the thousands of varieties, of the glorious range of greens and its amazing habit of carpeting walls, trees and banks in a luxurious type velvet or ferny down. So you can easily imagine my joy when I found out that scientists use it as a bio-indicator for measuring air pollution.
Here is a specimen of moss photographed using the scanning electron microscope, even at only forty times magnification it is a joy to behold.
The next photograph shows James, senior lab technician, putting the tiny piece of moss into the machine to cover it with a fine layer of gold particles to avoid any moisture, still present in the specimen, reacting with the electricity.
