Trees grow gold? Scientists reveal nature's surprising secret.
Gold can indeed be found in nature, not just in mines. Scientists have discovered that some trees can absorb gold from the soil.
The truth behind trees and treasure is stunning. Spruce trees in Lapland, Finland, are known to take up gold. Tiny gold nanoparticles are found in their needles.
This process happens when gold in the soil becomes soluble. The tree's roots can then absorb it. It moves up through the plant. This can happen over a year.
Researchers found up to 1.5 grams of gold per ton of soil. This is a small amount. But it shows a natural way gold moves. This discovery could lead to new ways to find and extract gold.
