树确实可以摇下钱——至少在澳大利亚如此。澳大利亚研究人员在一些桉树的树叶里发现了黄金颗粒，显示这些树下埋藏着金矿。 他们认为这一发现提供了勘探金矿的新方法。研究人员使用澳大利亚的同步加速器在一些树的树叶、枝丫和树皮里发现了微量的金子。每棵树所含的金粒非常少。计算发现，一个金矿周围生长的500棵树上收集的金子才能打造出一个金戒指。研究人员说，这些树就像吸泵一样，从根部吸收水，因此将微量的金子吸收，树的脉络将金子一直送到树叶子上。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.
