Humble fungi found in most back gardens could help clean up battlefields contaminated with depleted uranium.
At present, sites can be partial decontaminated by physically collecting and disposing of fragments from shells. However, radioactive particles and dust from explosions remain in the soil, preventing full reclamation.
Now, a research team in Scotland has established that common fungi can grow on and chemically lock away the offending uranium. As their hyphal filaments sprawled across fragments of depleted uranium, the tubules gradually became coated in a yellowy mineral.
