DNA samples often convict criminals. But many of today's forensic tests are so polluted by soil, tobacco and food remains, for example, that they can not be used. Now researchers in Sweden have improved a critical part of the analysis process. The first findings indicate that the new method strengthens the DNA analysis so that previously negative samples yield positive and usable DNA profiles.
