Within the world’s oldest crystals, collected from the Jack Hills in Western Australia, lie the remains of even older rocks—some of which have been reprocessed by magma into the remaining crystals. Using machine learning, geologists have revealed that a third of these ancient rocks were sedimentary. This means that more than four billion years ago, … Read more
The path to quantum supremacy is complicated by a fairy tale challenge: how do you carry a cloud without changing its shape? The possible solution sounds almost as fantastic as the problem. You could make the cloud dance as it travels, to the beat of a unique material known as a time crystal. Krzysztof Giergiel … Read more
Grenades have fascinated humans for millennia. The ancient Egyptians decorated their jewelry with garnets, and the Greeks called them “lamp stones” because they believed they could help them see in the dark. Recently, crystallized garnet particles have highlighted a fascinating geological link between Australia and Antarctica, uncovering an ancient Antarctic mountain range now under ice. … Read more
A new technique that produces 3D models of individual crystals has opened a window for scientists to see the subtle deviations that emerge from their otherwise perfect patterns. Researchers at New York University (NYU) went back to the drawing board to look deep into solids made up of repeating units and determine how they grow. … Read more
The world’s oldest crystals show evidence of exposure to both fresh and salt water during their formation, a new study reports. This indicates that the very early Earth had both oceans and land on which rainwater could collect. Although it is hell in many ways, it indicates a planet much more similar to the one … Read more
