• Resumen

  • The article presents questions and answers about how long a person can survive without food and how scientists detect new elements. How long can a person survive without food? Alan D. Lieberson, an attorney and the author of "Treatment of Pain and Suffering in the Terminally Ill and Advance Medical Directives," explains: The duration of survival without food is greatly influenced by body weight, JOURetic variation, other health considerations and, most important, the presence or absence of dehydration. A 1997 article in the "British Medical Journal" by Michael Peel, senior medical examiner at the Medical Foundation for the Care of Victims of Torture, cites well-documented studies reporting survivals of other hunger strikers for 28, 36, 38 and 40 days. How do scientists detect new elements that last only milliseconds? Todd M. Hamilton, associate professor and chair of the department of chemistry at Adrian College, provides an answer: Even elements that exist only briefly before decaying leave behind a calling card, in the form of an energy signature.
