Addendum, May 2005

After I had received the Prize in 1989 until my retirement in October 2002 I continued my single electron and single ion work with my associates. In the 1990s, stimulated by the life extension work of Roy Walford I shifted my main effort more and more into this and the Health and Nutrition fields.

Hans Dehmelt

On my University website http://faculty.washington.edu/dehmelt/ are some examples of work in progress. I also published 2 papers, Re-Adaptation Hypothesis: Explaining Health Benefits Of Caloric Restriction & Healthiest Diet Hypothesis: How to Cure Most Diseases? in the peer-reviewed journal Medical Hypotheses. Recently the Karolinska Institute invited me to nominate candidates for the 2005 Prize which I did. Also the journal Theoretical Biology and Medical Modeling asked me to publish my expanded next paper The Healthiest Diet: It Cures Most Diseases with them which I will do. My retirement from teaching was celebrated by a Fest & Festschrift An Isolated Atomic Particle at Rest in Free Space: A Tribute to Hans Dehmelt, Nobel Laureate, E. Norval Fortson and Ernest M. Henley, Editors.
