These Tiny Diamond Nanothreads Could Someday Support A Space Elevator

A team of scientists just strung heaps of the world’s smallest diamonds into superstrong nanothreads. That makes for one impressive (and basically invisible) necklace, but the applications of these nanothreads don’t end there. They could someday help string up a lift to space — just like in science fiction.


Scientists Use World's Largest Laser To Recreate Jupiter's Core

It is not pleasant inside the core of Jupiter — or any other planet for that matter. However, gaining a better understanding of what’s going on in there is key for understanding how these planets form. That’s why a team of scientists at Lawrence Livermore National Laboratory recently used diamonds and lasers to recreate those very conditions.


The Huge Diamond Mine That Helped Build The Soviet Union

Building empires takes money. And building industrial empires takes diamonds, not just for cash, but for the machines and tools that need them to operate. In a remote corner of Siberia, the Mir diamond mine was responsible for funelling diamonds into building the USSR — and it left behind a pit that stretches almost 2km across the surface of the Earth.


Watch This Diamond-Dusted Robot Saw Through Marble Like It's Hot Butter

There are lots of fun ways to watch machines show-off: see them play massive Jenga games; ooh and aah as they draw peens and portraits; or, in the case of Carrara Robotics, check out a wire-saw saturated with diamond dust slice through a chunk of marble like it it’s absolutely nothing.


The Entrance To Hell Is In The Centre Of Asia, And It's Terrifying

You are looking at the city of Mirny, located right in the heart of Asia, in the Republic of Yakutia, an estate associated to the Russian Federation. That terrifying hole is an open quarry 525m deep and 1.2km in diameter right next to the city itself. It looks like the gates of hell to me.


Researchers Develop A Way To X-Ray Rocks To Find Hidden Diamonds

It’s no surprise that the diamond industry is willing to spend whatever it takes to make the process of mining precious gems even more profitable. And while it already relies on X-ray technology for spotting diamonds on the surface of mined ore, researchers at the Fraunhofer Institute’s Development Center for X-ray Technology EZRT have developed a way to now spot them buried inside rocks.


Rare Diamond Reveals Existence Of Water Deep Inside Earth's Mantle

This battered diamond has survived a journey to hell and back,” and it has a pretty specular story to tell. Spat out from deep inside the earth, it is our first direct evidence for a scientific theory that says that vast amounts of water are trapped deep inside Earth’s mantle.


Researchers Find New, Easy Way To Turn Graphite Into Diamond

Since graphite — the dark material used in regular old pencils — and diamonds are both made from carbon, it’s technically feasible to turn the former into the latter. You just need to apply a little pressure — about 150,000 times what the atmosphere on Earth’s surface is like. But researchers at Stanford University claim to have found a shortcut.


How To Tell Real Diamonds From Fake

The jewellery market has been flooded with synthetic stones over the last several years; not just lab-grown gems but flat-out fakes. Here’s how to tell if your rock is the real McCoy and not just a shiny bauble.


This Is The Oldest Fragment Of Earth Ever Found

You’re looking at the oldest fragment of Earth ever found: a zircon 4.375 billion years old, something that has deep implications in our understanding of the planet’s formation. While some scientists said other samples weren’t genuine, new research just published in the journal Nature Geoscience proves that this is the real McCoy.
