The first step in the repair of DNA damage is lesion detection. In this issue, Scrima et al. (2008) report the structure of the complex of DNA Damage-Binding Protein 1 (DDB1) and DDB2 bound to a DNA photodimer, providing critical insight into the repair of DNA damage caused by ultraviolet light.

A simple modification is made to the ultraviolet scanning technique for the detection of the tryptophan notch which is characteristic of haemoglobins of fetal origin. This involves a differential scan using Hb A solution in the reference compartment. This technique has all the advantages of the standard scan method but extends the scope of it by being much more sensitive and decisive.
