For those unclear on what exactly bioethics encompasses, the Nuffield Council on Bioethics website is a great place to become acquainted with this field. Visitors can click on "Further Information" at the top right hand side of the page to find the "Faqs" link, and then click on "What is Bioethics?" The study of bioethics includes topics such as xenotransplantation, which is an animal to human organ transplant, prenatal screening, genetically modified crops, and patient confidentiality. The Council's current work, found under the link "Our Work" at the top of any page, addresses online medicine and dementia. The Council's members include physicians, theologians, lawyers, philosophers, and scientists. Each bioethics issue the Council has addressed has an accompanying paper, which can be found under "Publications" near the top of the page. Each paper can be downloaded free of charge for one week after publication.
