25% of papers published in cancer biology journals contain signs of ‘data duplication’, which can be a sign of scientific errors or even misconduct that’s according to a remarkable paper just published in science and engineering ethics by a norwegian cancer researcher, morten p oksvold. Deduplication works by creating a data fingerprint for each object that is written to the storage array as new data is written to the array, if there are matching fingerprints, additional data copies beyond the first are saved as tiny pointers if a completely new data item is written – one that the array has not seen before – the full copy of the data.
