This is a picture of bacteriophage Epsilon15 taken at a 4.5 angstrom resolution, the highest resolution achieved for a living organism of this size. To give you a size scale about 1 million angstroms is the diameter of a human hair. That is incredibly small and the researchers want to push it to 3 or 4 angstrom resolution, which would allow them to visualize individual amino acids in a protein chain. This work will probably be invaluable in determining just how viral infections take place at the cell to virus surface. Stay tuned...
