Afghanistan has vast mineral resources that have long attracted interest from outside countries, but a lack of infrastructure and political instability means they’re unlikely to aid its economy now.
Manufacturers of dietary supplements aren’t required to provide warnings to consumers about their potential risks. Here’s what to look out for.
Fool’s gold, or pyrite, is made of worthless iron disulfide, but can contain tiny amounts of the real thing. Using an ‘atom probe’, research has uncovered a new way gold atoms can hide in pyrite crystals.
From orange juice, to tea and coffee, to alcohol — different drinks can have different effects on iron absorption. This is worth thinking about if your iron levels are low.
Wind turbines and fighter jets both rely on imported critical minerals.

Right now, the nation is almost entirely dependent on other countries for minerals that are used in everything from wind turbines to strike fighters and satellites.
4 billion years ago, the Earth was composed of a series of magma oceans hundreds of kilometres deep.
The rocks provide rare evidence of a time when Earth's surface was a deep sea of incandescent magma.
A copper mine in Phalaborwa, South Africa. The African continent is home to vast mineral resources.
It seems the production of Earth science knowledge in Africa is simply not progressing, despite the world’s interest in (and exploitation of) the continent’s mineral wealth.

Companies are eager to mine the deep ocean for valuable mineral deposits. But scientists are concerned about impacts on sea life, including creatures that haven’t even been discovered yet.
Weathering of rocks like these basalt formations in Idaho triggers chemical processes that remove carbon dioxide from the air.
To avoid global warming on a catastrophic scale, nations need to reduce emissions and find ways to pull carbon from the air. One promising solution: spreading rock dust on farm fields.

Researchers are turning microbes into microscopic construction crews by altering their DNA to make them produce building materials. The work could lead to more sustainable buildings.
This started as a mountain range.
Sand may seem abundant when your toes are buried in it, but it’s becoming scarce along many coastlines around the world.

Manufacturing minerals is an expanding field of study. Making more of them could help alleviate various pressures faced by our growing population. But how are they made, and where can they be used?
The view of our planet from aboard the International Space Station.
Of all the planets in the solar system, there’s a reason we call Earth home. It’s made of just the right stuff. It’s not too small, or too big, or too hot or too cold. It’s just right.
Are the celebrities onto something with their IV vitamin cocktails? Let’s look at the evidence before rushing to the therapy lounge.
If their social media accounts were anything to go by, celebrities can’t get enough of vitamin and mineral infusions, or vitamin drips. Now therapy lounges are popping up for everyone else to try.
One recent study revealed no evidence that selenium supplements help prevent diabetes, even in geographical areas where there are relatively low amounts of selenium in the natural diet.
Most vitamins and other nutritional supplements are unlikely to prevent chronic disease. Invest in good quality foods, sleep and exercise instead.
