Finnish researchers discovered tiny gold nanoparticles within Norway spruce needles, a process seemingly driven by microbes. Specific bacteria, living in biofilms inside the needles, transform soluble gold from soil into solid particles. This groundbreaking finding could revolutionize gold exploration, making it greener and more sustainable by using plants as indicators and potentially for metal recovery.from Science News: Fresh Discoveries, Research & Breakthroughs https://ift.tt/aoRFPSN
