Somebody was absolutely minted back in medieval France!
I was never really a fan of gold, but knowing where it originates somehow makes it much more beautiful.
Putting the ‘physics’ back into ‘bling’.
Who said money doesn’t grow on trees? Take this grandpa!
The first images of Viking treasure, stashed in a pot more than 1,000 years ago and buried in a field in Galloway, have been made public by the conservators working to preserve them. The items, including six silver disk brooches, a gold ingot and Byzantine silk, are not currently on display.
In a time where virtually all labor was muscle-driven, having access to a material that can make your tools bend a bit instead of breaking or make your sword shatter an enemy’s weapon was like playing life with cheat codes.
Imagine a nugget of real, 20 carat gold floating merrily on the milk foam of your cup of warm cappuccino — scientists from ETH Zurich have found a way to do it. It’s not super-cappuccino, or diamond-strong foam — scientists led by Raffaele Mezzenga, Professor of Food and Soft Materials at ETH have produced a novel foam of gold, a three-dimensional material that is actually mostly…empty.
A team of archaeologists working in Denmark have made a puzzling discovery: they found nearly 2,000 spectacular gold spirals dating from the Bronze age. The reason why they were made, especially in such a large number, is a mystery and the trove baffled scientists. The spirals are made from pure gold, hammered down to just 0.1 millimeters thick, and measure up to
Research based on recent observations of a nearby gamma-ray burst, GRB 130603B, help explain how gold, silver and other heavy metal atoms are created.
At a recent meeting of the of the American Chemical Society, researchers proposed a novel source of valuable metals: waste water. They proposed a method that could be used to extract valuable metals like gold, silver or titanium which end up in waste water plants via the city’s sewage.
British researchers have demonstrated three ways gold nanotubes can be used against cancer: 1) high resolution in-vivo imaging; 2) drug delivery vehicles; 3) agents that destroy cancer itself. Their work shouldn’t be viewed as yet “another” hack that seeks to eradicate cancer. We need to be more realistic than this. Instead, the findings have the potential to be a great measure that both diagnoses and treats cancer at the same time, complementing conventional surgery and, hopefully, avoiding the need for chemotherapy.
There are millions of dollars in gold and other metals in the sewage sludge in major cities. A new study has found that in a city with 1 million inhabitats, there’s as much as $13 million worth of valuable metals, including gold and silver.
Why gold is important and where it came from. All your questions are answered in this article.
Whenever you buy an electronic, that ‘Made in [country]‘ label only shows where it was maufactured or put together – there’s no way of knowing where the materials for it came from; usually, they come from troubled countries, such as the Democratic Republic of Congo. But today Intel CEO Brian Krzanich promised at the Consumer Electronic Show (CES) in Las
A new theory based on a simple but viable geologic model claims that over 80 percent of all commercial gold deposits were formed in a flash. Gold seams are formed when mineral-rich waters flow through networks of cracks in rocks some 5-30 km deep. But the exact mechanism through which the gold is deposited is not really that well documented.
No, this isn’t some kind of reinvented alchemy or optical illusion. Scientists at University of Southampton have changed the colour of gold, silver and other metals without coating, by using a nanotechnology patterning technique. Applications may include harder to forge currency or encryption of valuable documents, among other. The team of researchers embossed the surface of metals with tiny raised or indented
The Israel Antiquities Authority said that archaeologists found a 2,000-year-old gold earring next to the walls of the ancient city, under what was a parking lot. This is not the first amazingly well preserved piece of jewelry found in Israel, but many jewish works of art are often found in other places (such as the earliest gold scroll found in
