That little bead right there? That’s all the gold in four and a half pounds of electronics waste. And it took so very much work to get there.
Metallurgist Grigory Raykhtsaum shows Smithsonian three different ways to test if something is solid gold: a color test, a thermal conductivity test, and a particle test. It’s all computerized now so all he has to do is scan the object to get a read on the color, zap it with an electrical current to measure the…
Gold is so malleable that a single gram of it can be stretched into a strip nearly two miles long. A tiny little coin can be pressed into a 0.0001-millimeter-thin golden rectangular sheet the size of a tatami mat. So leave it to the talented artisans of Japan to transform a tiny bit of gold into shimmering gold leaf…
Over the last year, Apple processed 90 million pounds of electronics that were unwanted or broken. It turns out they were nearly worth their weight in gold—a substance which is used heavily in electronics for its conductivity and resistance to corrosion.
This is the least dense gold nugget in the entire world. It can be held up with a feather. And it’s supported by a space-age material often dubbed “frozen smoke.”
Where does gold come from? The answer: space, basically. Supernovae, specifically. Alchemy, sort of. So gold doesn’t actually originate from the core of Earth but actually from a star explosion that showers the universe with debris and well, gold. That means there’s not that much of it actually on Earth (all the gold…
Android Wear watches are cool and all, but none of them are especially fancy. (Even the new Moto 360, with its flat tire screen.) Until now, at least. An alligator leather wristband, 23-karat gold plating, and a $1000-plus price tag mean the LG Watch Urbane Luxe is a particularly niche geek accessory.
Starting today, you can buy a gold iPod Touch. It’s actually not as lame as it sounds. Beneath its golden shell, the iPod is starting to look a little bit like the low-cost phones that so many of its competitors are working on, too.
One of the reasons I desperately want to time travel is to blow the minds of people in the past with just the simplest of things today. Imagine going back hundreds of years and baking this gold 24 'carrot' cake. With a few drops of food coloring and a few edible gold leaf sheets, I'd be hailed as the greatest…
The picture above is terrible. It shows the catastrophic effects of the deforestation caused by the current gold rush in the tropical forests of South America. The consumption of gold worldwide is increasing in the last years due to the global economic crisis and the instability in the financial markets.
As far as Apple announcements go, today's "Spring Forward" event was decidedly lacking in big reveals. The only real curveball was Apple's reveal of a brand new MacBook—one that comes in both gold and space gray, no less. Still, there were some fun little surprises thrown in the mix.
Nearly half the gold ever mined comes from the Witwatersrand Basin, a layer of gold-flecked rock that spreads out under South Africa. The mines there are famously deep and prolific. Why is there so much gold concentrated in this one small part of the Earth's crust?
There's gold in them thar sewers—and silver and platinum and copper, too. A study by Arizona State University (ASU) researchers estimates there is $13 million worth of precious elements in the sewage produced by a million-person city every year. Never think of sewage as stinky worthless waste again.
First it was there. And now it's not. On Friday, a Redditor spotted a new addition to the Moto 360 lineup though a link emailed out by Motorola itself. The curious timepiece in question is the gold-rimmed device on the top row center.
Black and white are so passé. The new hotness is $13,700 gold Xbox Ones and PS4s, now for sale in Dubai.
Your gadgets contain tiny specks of precious and rare earth metals—we rely on these dust-sized particles, which are so small they're often not recycled because the cost of recycling outweighs the value of the metals. But according to the American Chemical Society, the overall value of these minute materials is massive.
Before the Emmy winners are announced tonight and they grasp their shiny trophy on stage in front of millions, each one of those statuettes began as a pool of pure virgin metal, liquified at 700 degrees. That's hot.
