Microbe Creates Gold, Paving Way for Sustainable Mining
Imagine a tiny bug living in super-toxic places.
This bug, called Cupriavidus metallidurans, eats gold and copper.
When it does, it changes the gold inside its body and poops out tiny pieces of real gold!
Scientists are studying this amazing bug to learn how it does this.
They think they can use this bug's tricks to get gold out of old electronics or mine waste without harming the environment.
This way, we can get gold in a cleaner and safer way.
Scientists discovered a microbe, Cupriavidus metallidurans, that converts toxic metals into gold.
The microbe survives in soil with high concentrations of heavy metals like copper and gold.
It transforms toxic gold ions into harmless particles, expelling them as solid gold nuggets.
The microbe's gold-making process could inspire new methods of biomimetic mining.
This could allow for safer and more sustainable gold extraction from waste and low-quality ores.
