An Interview with Mark Plotkin, Ph.D., Executive Director, Ethnobiology and Conservation Team, and author of Tales of the Shaman's Apprentice.

In this interview, conducted at the 1996 Access Excellence Summit, Dr. Plotkin gives some background on the field of ethnobotany and describes both the process and romance of seeking out healing substances in the tropical rain forests.


Dr. F.A. Murphy & Mad Cow Disease, the BSE Epidemic in Great Britain

The announcement by British health authorities that bovine spongiform encephalopathy (BSE), also known as mad cow disease, may have been transmitted to humans has led to a chaotic situation in the UK with ripple effects occurring throughout Europe and the rest of the world. What is BSE and what is its relation to scrapie in sheep and Creutzfeldt-Jakob disease (CJD) in humans?


Dr. Dennis Bier & USDA Diet Guidelines

Every five years the USDA releases new dietary guidelines. Every time they do this the guidelines are different from the ones before. This is because a panel of experts from across the country considers thousands of new studies and forms a consensus based on that data. I spoke with one of the panel members, Dennis Bier, M.D. about the new guidelines. Check the resource guide at the end of the interview for more information.


Food For Thought: An Interview with Nutrition Scientist Dr. Paul Saltman

We are barraged by the media with endless claims and promises about the value or risks of what we eat and drink and what we take in the way of dietary supplements. Where is the science? I spoke with nutrition science authority Dr. Paul Saltman, professor of biology at UCSD, and author of various texts and popular books about the science of nutrition, in an effort to separate some nutrition facts from food fiction.


I. Persson Discusses Hormone Replacement and Cancer Risk

Even the most complicated scientific studies depend on the fundamentals of good design and methodology. When the studies are epidemiological in nature, the picture becomes even more complex. Recent epidemiologic studies have produced contrasting results regarding the potential risk of hormone replacement therapy and risk of breast cancer in menopausal women. How does one go about sifting the scientific wheat from the statistical chaff? I asked noted breast cancer researcher and epidemiologist Ingemaar Persson, M.D., of the department of cancer epidemiology, University of Uppsala, Sweden, to clarify some of these issues.


An Interview with Dr. F. A. Murphy, Ebola Virus expert

The book "The Hot Zone" and the film "Outbreak" have seized the public's imagination and brought into focus many issues regarding the very real threats posed by new and emerging diseases. In this interview we talk with Frederick A. Murphy, D.V.M., Ph.D., Dean of School of Veterinary Medicine, UC Davis.

At the time of the 'Reston incident', Dr. Murphy was the director of the National Center for Infectious Diseases at the CDC in Atlanta. Dr. Murphy is considered one of the world authorities on viruses. He was the first one to look at Ebola virus 'face-to-face' in the electron microscope. Dr. Murphy appears in "The Hot Zone" and his now famous photo of the Ebola virus appears in the film "Outbreak".


An Interview with Epidemiologist Dr. Charles Hennekens

An interview with noted epidemiologist Charles Hennekens, M.D., Professor of Medicine, Harvard Medical School, and Chief, Division of Preventive Medicine, Brigham and Women's Hospital, Boston, MA.

We are bombarded with endless, sometimes conflicting, media reports announcing that this food is good for you or that activity is bad for you. Where do these claims originate and how much scientific merit do they have? For example, most of us have heard that low doses of aspirin taken over the long term significantly reduce the risk for heart attack. Dr. Hennekens is the director of the Physicians' Health Study, the large long-term study which demonstrated conclusively that aspirin did reduce the chance of a first heart attack in middle-age men. Another part of that trial is evaluating the potential role for the antioxidant vitamin beta-carotene in protecting against heart disease and cancer, and will be completed next year. I caught up with Dr. Hennekens at the annual meeting of the American Heart Association in Dallas and asked him to elaborate on the science of public health.
