Radiation damage to biological macromolecules: some answers and more questions

Introductory overview to the special issue papers on radiation damage to biological macromolecules.

To scavenge or not to scavenge, that is STILL the question

The reasons for the conflicting results on the efficacy of scavengers in macromolecular crystallography are examined in the light of some new results.

Optimizing the spatial distribution of dose in X-ray macromolecular crystallography

Simulated dose distributions for helical and translational macromolecular crystallography data-collection strategies are compared with that of a `standard' protocol as a step towards giving robust definitive guidelines to experimenters for optimizing the diffraction lifetime of crystals.
