Using plants to help locate landmines
OTTAWA (CP) - Researchers working for the Canadian and U.S. militaries are making progress in developing genetically modified plants that could help people around the world avoid death and injury from landmines.
The researchers at the University of Alberta, Duke University in North Carolina and other schools are trying to develop plants that will alert people to the presence of landmines by changing colour if their roots detect compounds, such as TNT, commonly used in mines.

Reminds me of how hydrangea blossoms will turn either pink or blue, depending on the acidity of the soil.
Plants have given us life-saving medications. This would be another contribution.
