The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the formula FeS2. This mineral's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.

Capturing this unique connection is Indonesian artist Elicia Edijanto, who depicts small, vulnerable children alongside creatures of the wild like elephants, wolves and bears. Created in stark black and white imagery, and using only watercolors, Edijanto creates dreamlike-scenes that are both tranquil and contemplative.

For more than 2,000 years, women from the Baiga tribe in the highland district of Dindori, in central India’s Madhya Pradesh state, have been tattooed.

As an American in 1990s Cuba, Tria Giovan risked being branded a traitor. But the photographer continued to visit and, from the dance hall to the hair salon, she captured the resilient spirit of the Cuban people.

Her trip required lots of planning – and patience. (Photo by Tria Giovan/The Guardian)

The tiny portions feature cuisine from all over the world, from ultra-American apple pie to Japanese ramen. The 22-year-old confines himself to cooking in a 2ft by 2ft box, so the only heat he can use comes from a tea light. Here: Jay cooks the ingredients of the tiny spaghetti on the tiny stove.
