Transparent iron? For the first time, an experiment shows that atomic nuclei can become transparent
At the high-brilliance synchrotron light source PETRA III, a team of DESY scientists headed by Dr. Ralf Röhlsberger has succeeded in making atomic nuclei transparent with the help of X-ray light. At the ...

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 ...

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 ...
