Doc Ruby writes "After an 8-year-long court battle, Welsh activists have finally been allowed to released a Russian study showing an increased cancer risk linked to eating genetically modified potatoes. While the victory of the Welsh Greenpeace members in the courtroom would seem to vindicate the work of the Russian scientists that did the original research, there are still serious questions to be answered. The trials involved rats being fed several types of potatoes as feed. The rats who were fed GM potatoes suffered much more extensive damage to their organs than with any other type; just the same, serious questions remain about the validity of the findings. The Welsh group wants to use this information to stop the testing of GM crops in the UK, tests currently slated for the spring of this year."
