Hundreds of regular patterns spontaneously emerge on a small germanium chip. A curiosity about tiny dots on a germanium wafer with metal films led to the discovery of intricate spiral patterns etched ...

A lab mistake led to self-forming spiral patterns on metal surfaces, revealing chemical-mechanical interactions.

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

Even the little-understood Oort Cloud, at the outer edges of our solar system beyond view, has a partly spiral structure.

On a whim, she looked at the dots under a microscope and couldn't believe her eyes. Beautiful spiral patterns had been etched into the germanium surface by a chemical reaction. Wong's curiosity ...

The spiral is composed of billions of icy bodies surrounded by a shell of comets called the Oort cloud. Even though the Oort cloud lurks at the edge of our own planetary system and is about 99,000 ...

If confirmed, this discovery would indicate that the Sun’s gravitational reach is not the only factor shaping our solar system’s outer shell. The unexpected spiral formation is likely the ...
