1) A 70-kilogram adult human body contains roughly 0.2 milligrammes of gold. The element has been discovered to have key health benefits, including aiding in the maintenance of our joints and facilitating the transmission of electrical signals throughout the body.
2) According to Weatherley and co-author Richard Henley of the Australian National University in Canberra, the water inside the void instantly vaporises, flashing to steam and forcing silica, which forms the mineral quartz, and gold out of the fluids and onto nearby surfaces.
3) The gold is buried roughly 100 feet underground at both sites. During periods of dryness, when the tree's roots stretch down further and deeper for a drink, the team believes that ionic gold gets absorbed through the tree's deep roots. The ions are subsequently dispersed throughout the tree's cells, where they crystallise.
4) The gold medal is constructed of pure silver that has been gold-plated, with approximately 6 grammes of gold out of a total weight of 556 grammes. If you melt down a silver medal, it's worth roughly $450.
5) Scientists eventually estimated that the Sun has over 2.5 trillion tonnes of gold, enough to fill the oceans of the Earth and more. Still, that's only eight gold atoms for every trillion hydrogen atoms, a negligible quantity when compared to the Sun's mass.
6) Dubai's cash-rich government has devised an unorthodox method of incentivizing individuals to lose weight: rewarding them in gold for each kilogramme lost.
7) 'Aurophobia' refers to a fear of gold. People who suffer from this phobia frequently have panic episodes when they come into contact with or near the precious metal.
8) The only metal that is yellow or "golden" is gold. Other metals may turn yellow after they've oxidised or reacted with other chemicals, but only after they've oxidised or reacted with other chemicals.
9) Metallic gold with a high purity is odourless and tasteless. Because the metal is non-reactive, this makes sense. Metallic elements and compounds get their flavour and odour from metal ions.
10) Nearly all of the gold on Earth originates from 200 million-year-old meteorite impacts.
