Core Viewpoint - The discovery of rare earth elements in the plant species "Osmunda japonica" and their self-assembly into a mineral called "lanthanite" presents a new sustainable approach for rare earth resource utilization, potentially reducing ecological damage from traditional mining methods [1][5]. Group 1: Research Findings - Researchers found that rare earth elements are absorbed by Osmunda japonica and crystallize into lanthanite nanoparticles within the plant's vascular bundles and epidermal tissues [2][4]. - This process acts as a self-protection mechanism for the plant, effectively "packaging" toxic rare earth ions into a mineral structure, thereby detoxifying them [2][4]. Group 2: Implications for Sustainable Utilization - The formation of "biological lanthanite" in Osmunda japonica is pure and non-radioactive, offering a promising green extraction method compared to traditional mining, which often involves radioactive elements [4]. - The findings suggest that cultivating hyperaccumulator plants like Osmunda japonica could facilitate soil remediation and recovery of valuable rare earth elements, achieving a "repair and recovery" green cycle [5].
