Tid Bit: Gold Really Does Grow on Trees!


I noticed this article earlier in the week and, although it’s not strictly chemistry, it’s a very interesting piece of science.

Australian scientists have published a paper in Nature Communications showing that eucalyptus plants 40 metres above gold deposits incorporate the precious metal in their leaves.

It’s a very interesting an surprising discovery, as gold is toxic to plants. This work gives an insight into the mechanism of gold uptake into plants, and could also pave the way for a new method of finding gold deposits in areas where traditional drilling isn’t a convenient option.

With gold reserves becoming increasingly sparse and the demand for gold increasing all the time, new techniques for gold discovery are a real need, and this work could make a real difference in this area.
