Objects younger than 500 years old are rarely radiocarbon dated.Natural and anthropogenic fluctuations in environmental radiocarbon levels mean that organisms living in different centuries within the past 500 years can have identical radiocarbon contents.It is recognized by the Australian government in the ERA as a peer-reviewed publication of international standing.View Journal | Current Issue | Register The Arizona Working Papers in Second Language Acquisition and Teaching is a publication of the University of Arizona Interdisciplinary Ph. Program in Second Language Acquisition and Teaching (SLAT).The ratio of radiocarbon to stable carbon in an organism depends on the environment until death, then decreases predictably over time. By measuring this ratio, we can calculate the age of a sample. But radiocarbon comprises only about one trillionth of the carbon in living organisms. Painstaking work is required to isolate and measure only the original sample carbon and produce a reliable radiocarbon date, one that is scientifically accurate and numerically precise. At Aeon Laboratories, we pursue this goal with innovative proprietary technology, the skill and discipline required to execute exacting procedures, and a thorough understanding of chemical and biological principles.

We also publish conference proceedings and monographs on topics related to our fields of interest.

In keeping with the University of Arizona’s mission as a public research university, this journal will continue to serve as a forum for innovative scholarship and research on the region.

At Aeon Laboratories, we use radiocarbon dating to answer this question for materials as old as 40,000 years, and in some cases, even older.

Plant remains, charcoal, shells, bone, and other materials that contain carbon are all potentially suitable for radiocarbon dating.

University of Arizona history students are able to work with the journal as both editors and authors.

Our purpose is to promote scientific achievements of University of Arizona College of Medicine students, to highlight cutting-edge research at Banner University, and to inform the student body of research opportunities. The University of Arizona Journal of Medicine is a biannually-released journal that showcases basic science, clinical and translational research, humanities essay and artwork.
