The posts on this blog site represent the collective views of leading experts in the fields of biotechnology, endocrinology (the study of hormones), food security, and food safety. The intent is to provide a public forum for presenting science-based facts about numerous issues that relate broadly to the use of biotechnologies and technologies for food production. Many science-based perspectives that relate to the use of biotechnology in animal and plant agriculture are discussed. Some topic areas pertain to the use of recombinantly-derived bovine somatotropin (rbST), animal cloning, and genetically modified (GM) crops.
