Rapid advances in the field of molecular and cellular biology have unwillingly unleashed the potential for creating viruses and bacteria more virulent than nature's worst. In the summer of 2002, Researchers at the State University of New York at Stony Brook described the first de novo biochemical synthesis of a virus, based on published gene sequence information and using "off the shelf" commercially available DNA material. After they pieced together genetic sequences to form a full-length poliovirus, they successfully replicated and translated this material cell-free in test tubes. The resulting nucleic acids and proteins were then able to assemble spontaneously into fully infectious viral agents. The scientists began their work from genetic blueprints that exist in the public domain, that is, in published journal articles and on internet databases. The ability to manufacture an infectious agent from scratch using preexisting, published knowledge is an unsettling development. The theoretical possibility that current knowledge could permit the creation of potential agents of biological warfare generated intense media interest around the world. As a result of studies like that at Stony Brook, an ethical debate has arisen over whether such research should be pursued, and if so, whether the details of such research should be published. Some argue that the pursuit and publication of such research unwittingly aids would-be terrorists; others argue that the dissemination of information is necessary for the effective sharing of research within the scientific community and for science to progress.
In 250-300 words, explain which side of the debate you support and why (TYPE ANSWER PLEASE).

Visit or call a store with a plant nursery (Walmart, Home Depot, etc.) and describe the planting of spinach to an associate or customer as if you were really having this issue. Ask them what they recommend you should do. Do not mention the scientific method or even imply any of these steps while discussing your 'problem.' Listen closely to see if the associate/customer's recommendations align with what is expected for the scientific method.
