Physicists develop model that pushes limits of quantum theory, relativity
All of the matter in the universe -- everything we see, feel and smell -- has a certain predictable structure, thanks to the tiny electrons spinning around their atomic nuclei in a series of concentric shells or atomic levels. ...

Researchers discover why atoms in solids show a preference for certain structures
(PhysOrg.com) -- Nature likes some symmetries, but dislikes others. Ordered solids often display a so-called 6-fold rotation symmetry. To achieve this kind of symmetry, the atoms in a plane surround themselves ...

Computer memory takes a spin: Physicists read data after storing them in atomic nuclei for 112 seconds
University of Utah physicists stored information for 112 seconds in what may become the world's tiniest computer memory: magnetic "spins" in the centers or nuclei of atoms. Then the physicists retrieved and ...
