Every parents favorite line about how money doesnt grow on trees just became a little more irrelevant, thanks to a fascinating find down under. Researchers in Australia recently found gold—yes, real gold—in eucalyptus trees growing in the outback.A team of unlikely prospectors recently ventured into the arid land of the Goldfields-Esperance region in Western Australia, hoping to learn more about what was underneath its soil. The area earned its name for being rich in gold deposits—that were, however, notoriously difficult to find. So the researchers looked in an unlikely place: The trees.Eucalyptus trees in this region are known for their resiliency, and for roots that reach impossibly deep to find the groundwater needed to keep themselves alive. It just so turns out that the elusive gold deposits are down there, too.Chasing a longstanding rumor that the trees leaves get their gold luster from the deposits, the scientists analyzed the leaves of eucalyptus trees in the area—and sure enough, they found traces of gold. Apparently, the trees roots grew ten stories deep into the soil and absorbed gold particles from nearby deposits. To confirm that these particles came from the soil under the roots, they grew eucalyptus trees in gold-laced potting soil in a greenhouse. And sure enough—they found gold in those leaves, too.
