Money does grow on trees after all.

Australian scientists just discovered that eucalyptus trees, which can have roots more than 130 feet deep, sometimes have gold in their leaves. They suck up water from deep underground, and if there’s gold ore nearby, microscopic pieces of gold come up with it. That doesn’t make the trees a source of riches, but it does make it possible that prospectors could have a new way of locating gold. The same method will probably soon be applied to other valuable minerals in other parts of the world.

It also sounds like it offers a new reason to destroy forests to get at the stuff underneath them, which is a little less exciting.
