RNA mimic destined for synthetic genome US scientists have taken another step towards the goal of creating self-replicating molecules like those thought to have spawned life on Earth. The researchers made RNA-like polymers capable of copying short sections of genetic code that they suggest could act as genomes in synthetic cells.   |

Rotaxane molecule seen in action Researchers from the US and Japan have directly observed the ring of a rotaxane molecule shuttling along its spindle. The behaviour of the rotaxane is influenced by its molecular environment, something that is significant if the molecules are to be used as molecular machines. |
