The issue focused on medical education and research in medicine, science and technology. The researchers looked at studies published between 1998 and 2012 that studied scientific literature from academic medical centers or biomedical research labs. They found only 11 studies about genetic engineering research into specific diseases. In six of those studies, scientists gave laboratory animals genetic material created by molecular biology techniques to study how it affected their physiology. But researchers used genetic engineering for experiments involving genetic engineering research into genetic engineering research into Alzheimer's disease, autism, diabetes, obesity, HIV
