Zothecula writes: Most people’s image of plants is actually upside down. For most of our photosynthetic friends, the majority of the plant is underground in the form of an intricate system of roots. The bit that sticks up is almost an afterthought. That’s a problem for scientists trying to study plants because growing them in media that allow you to see the roots, such as hydroponics, doesn't mimic real soil very well. Now, a team of researchers at the James Hutton Institute and the University of Abertay Dundee in Scotland has developed an artificial transparent soil that allows scientists to make detailed studies of root structures and subterranean soil ecology on a microscopic level.
