Physicists at the National Institute of Standards and Technology (NIST) have for the first time coaxed two atoms in separate locations to take turns jiggling back and forth while swapping the smallest measurable units of energy. The technique directly links the motions of two physically separated atoms and might simplify information processing in future quantum computers and simulations.

To determine if a tissue biopsy reveals the presence of cancer, a histologist often screens for cells with an abnormal appearance or a specific visible trait such as a larger-than-usual nucleus. However, by the time a cancer is physically noticeable, the disease may be in its later stages and more difficult to treat. In an effort to identify the earlier-onset, more subtle chemical changes occurring in a cell heading toward malignancy, researchers have developed a technique that slices off the top of a cell and makes the structures accessible to spectroscopic examination of their chemical "signature."

Some recently developed bulk metallic glasses (BMGs) - metal alloys that have randomly arranged atoms as opposed to the orderly, crystalline structure found in ordinary metals - can be blow molded like plastics into complex shapes that can't be achieved using regular metal, yet without sacrificing the strength or durability that metal affords.
