3D Structure Of HIV Is "Revealed"

The 3D structure of the virus which causes Aids has been revealed for the first time, scientists say. The variable size and shape of HIV has made it hard to map, the team said in the journal Structure. So the UK-German team took hundreds of images of viruses, that are 60 times smaller than red blood cells, and used a computer programme to combine them. Oxford University's Professor Stephen Fuller said the 3D map would assist in understanding how the virus grows.
