Situated equidistant from Raleigh, Durham, and Chapel Hill, N.C.--smack in the middle of the Research Triangle--sits the only National Institutes of Health institutional campus outside of the Washington, D.C., Beltway. The National Institute of Environmental Health Sciences (NIEHS) is currently responsible for nearly 50 percent of all federally funded research on such subjects. It commands a diverse research agenda that covers populations and geographical boundaries far beyond the triangle or t

Researchers and bioethicists need to take advantage of events such as the recent publication of the HeLa genome to engage the public on topics of privacy, biobank regulation, and more.
A Science Publishing Revolution
Eugene Russo | Apr 15, 2001 | 7 min read
Scientists and publishers generally agree that the Internet is sparking a science publishing revolution.1 They have yet to agree, however, on how to cultivate that revolution without alienating one another. The latest effort to push the online publishing envelope has a sizable group of scientists threatening to boycott journals whose content is not freely available in a public database six months after publication. This call for a "public library of science" (PLOS) has already caused quite a sti

different things to different people. To the biomedical scientist it could include the crucial basic investigations that lead to a life- and cost-saving vaccine. By contrast, to a hospital's staff ethicist it could entail devising a policy of informed consent for experimental medical treatments. Health-care research, according to many experts, covers the spectrum from fundamental research projects like those in cell biology to such applied questions as how to lower costs yet maintain high-qua
