Gold growing on leaves? Scientists uncovered a strange forest phenomenon in Finland

Key points

• The strange forest phenomenon behind gold-filled leaves The significance of the discovery Gold in plants is not entirely new Why gold is unusual inside living organisms Could forests help future mining exploration?
• Deep inside the forests of northern Finland, scientists discovered something that sounded almost impossible at first: microscopic particles of real gold hidden inside ordinary tree needles.
• Researchers studying Norway spruce trees near the Kittila gold mining region found that the trees contained tiny solid gold nanoparticles absorbed from underground mineral-rich groundwater.
• The surprising discovery revealed a hidden partnership between tree roots, microbes and underground chemistry that slowly traps traces of gold inside plant tissues over many years.
• While the trees are not literally producing gold, the finding has opened new scientific discussions about how forests may help researchers locate hidden mineral deposits in a cleaner and less invasive way.The discovery took place in northern Finland near the Kittilä...
