A group of 64 scientists raised concerns over the panel selected by the National Academy of Sciences for its new study on genetically engineered crops, arguing that the group “does not contain the necessary expertise required” to fully answer the questions at hand. The panel put together for the study, entitled "Genetically Engineered Crops: Past Experience and Future Prospects,” falls short on biophysical science, social science and international expertise, and would benefit from farmer representation as well as a better gender balance among panelists, the scientists say in their August 4, 2014 letter.
