Heavy Metal-Eating "Superworms"
| Quote From Source: | Newly evolved "superworms" that feast on toxic waste could help cleanse polluted industrial land, a new study says.
These hardcore heavy metal fans, unearthed at disused mining sites in Britain and Wales, devour lead, zinc, arsenic, and copper.
The earthworms excrete a slightly different version of the metals, making them easier for plants to suck up. Harvesting the plants would leave cleaner soil behind.
"These worms seem to be able to tolerate incredibly high concentrations of heavy metals, and the metals seem to be driving their evolution," said lead researcher Mark Hodson of the University of Reading in England.
