The cooler, denser water then sinks into great depths and travels to the Antarctic and finally circulates back up to the Gulf Stream. (Copyright …

Two-atom reaction smallest chemistry experiment ever performed | research

Chemical reactions are performed at all scales, from microreactors and laboratory bottles to huge industrial tanks. US researchers have now taken things to extremes and made a response as small as possible. They used optical tweezers to hold a single atom of sodium and one of cesium, and combined them into a new molecule, an alloy of these two metals. …
