FBNCO: all the 2p-block elements in one molecule Scientists in Italy have made a molecule with one of each of the 2p-block elements. Well, almost. There's no neon in FBNCO but it would be a bit unfair to expect them to include an element with no known chemistry. |

Light makes molecule shine Researchers from Kyushu University in Japan have constructed a fluorescent molecule that can be repeatedly switched on and off. If a way can be found to switch individual, closely-packed molecules on and off, fantastic amounts of information could be stored in very small spaces. |
