The positions of all the atoms in a sample of a metallic glass have been measured experimentally — fulfilling a decades-old dream for glass scientists, and raising the prospect of fresh insight into ...

Hollow atoms are special atoms with multiple missing electrons in their inner shells, while their outer shells are still fully or partially filled with electrons. Studying the production mechanisms, ...

Add Yahoo as a preferred source to see more of our stories on Google. Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage Team ...

Vortices may conjure a mental image of whirlpools and tornadoes—spinning bodies of water and air—but they can also exist on much smaller scales. In a new study published in Science, researchers from ...

A cloud of ultracold atoms is like a motel with a neon “no vacancy” sign. If a guest at the motel wants to switch rooms, they’re out of luck. No vacant rooms means there’s no choice but to stay put.

Researchers at the Kastler Brossel Laboratory in Paris have made the most precise measurement of one of the fundamental constants, called the fine-structure constant, providing physicists with a vital ...

Matter is made up of very small parts called atoms. Atoms can combine in different numbers and in different ways to make different molecules. Atoms and molecules make up all of the different ...

Until now, atoms have never been imaged interacting freely in space, but a new technique known as non-resolved microscopy has changed that. MIT physicists were able to successfully capture images of ...

Cholesterol comprises carbon, hydrogen, and oxygen. It is a waxy, fatty substance that is solid and white or light yellow. Its chemical formula is C 27 H 46 O. This means it has 27 atoms of carbon, 46 ...
