Crystals have been found along human remains in several archeological dig sites. Primates of all stripes really love their ...

Crystals have repeatedly been found at archaeological sites alongside Homo remains. Evidence shows that hominins have been collecting these stones for as long as 780,000 years. Yet, we know that our ...

They gave quartz, calcite and other types of crystals to chimpanzees in a rehabilitation center. The apes responded with great interest, and the researchers ended up needing to trade large amounts of ...

The study suggests that both humans and chimpanzees possess a “shared cognitive predisposition” for crystals. Whenever such a trait emerges as common between two related species, it’s likely that this ...

When looking at calcite under a microscope, a scientist would immediately recognize the crystalline form of calcium carbonate by its rhombohedral appearance. That is, calcite is shaped like a ...

Using single calcite crystals with varying surface roughness allows engineers to simplify the complex physics that describes fault movement. Researchers now show how this simplification may lead to ...
