A New Rush to Find Gold in the Sierra Nevada Foothills.
Pummeling storms over the winter, along with copious spring snowmelt, have created optimal conditions for gold to emerge. In their lust for riches, the miners of the gold rush moved a gargantuan amount of dirt. A prominent geologist, Grove Karl Gilbert, calculated in the early…Read More
Earth’s gold came from colliding dead stars.
New observations confirm that colliding neutron stars produce short gamma-ray bursts. Such collisions produce rare heavy elements, including gold. All Earth’s gold likely came from colliding neutron stars. We value gold for many reasons: its beauty, its usefulness as jewelry, and its rarity. Gold is…Read More
Swiss researchers create unscratchable gold.
EPFL scientists have created 18-karat gold that’s harder than tempered steel and virtually unscratchable. By combining a gold alloy with boron carbide, an extremely hard ceramic that’s used in bulletproof vests, a team of EPFL researchers has succeeded in making the world’s toughest 18-karat gold…Read More
Research unveils birthplace of gold-rich stars by Royal Astronomical Society.
The simulated Milky Way-like galaxy at present taken from the simulation produced in the study. A team of researchers from the University of Notre Dame and Tohoku University have revealed the birthplace of so-called “gold-rich” stars-stars with an abundance of heavy elements beyond iron, including…Read More
Non-toxic technology extracts more gold from ore.
Study shows new chloride-based process recovers 84% of gold compared to the 64% recovered with traditional methods. Gold is one of the world’s most popular metals. Malleable, conductive and non-corrosive, it’s used in jewelry, electronics, and even space exploration. But traditional gold production typically involves…Read More
