cornfields could play a role in recycling old electronics




a new biochemical leaching process has been developed that uses corn stover as feedstock, and recovers valuable rare earth metals from electronic waste.



toyota's next ev motor could use 50 percent less rare earth metals




toyota has designed a magnet that halves the amount of rare earths needed in its electric cars, which could help mitigate the fall out of a looming materials shortage. like other electric carmakers, toyota has traditionally used neodymium, terbium and dysprosium in its electric vehicles, but it beli...



rare metals on mars and earth implicate colossal impacts




new research has revealed that a giant impact on mars more than four billion years ago would explain the unusual amount of "iron loving" elements in the red planet.
