'Real' computer virus

Digital life form.

Researchers in the US have constructed a virtual version of the satellite tobacco mosaic virus using more than a million 'digital atoms'. The researchers used one of the world's largest and fastest computers to simulate all the atoms in the virus and a small drop of water surrounding it. Because of the enormous computing power involved, the digital virus existed for only 50 nanoseconds.

The simulation and its implications for scientific research are detailed in the March issue of the journal Structure.
