Stable isotope mixing models are regularly used to provide probabilistic estimates of source contributions to dietary mixtures. Whilst Bayesian implementations of isotope mixing models have become ...

Over the past two decades stable isotope analysis has emerged as a cornerstone technique for verifying the authenticity and geographical origin of foodstuffs. By measuring the relative abundances of ...

Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of ...

The IAEA offers a variety of training courses in the fundamentals of isotope hydrology and isotopic analyses of stable isotopes, tritium, and noble gases. This course provides an overview of advances ...

Both radioisotopes and enriched stable isotopes are essential to a wide variety of applications in medicine, where they are used in the diagnosis and treatment of illnesses. In addition, extensive ...

Stable isotopes are safe, non-radioactive forms of common elements such as carbon, nitrogen and hydrogen that occur naturally in small amounts in the foods and water we consume every day. Because they ...

Examples of stable isotopes being used to support research include, studying water extraction methods from plants, to how habitat changes have incited more attacks by coyotes on humans. Stable ...

An international science team has made significant strides in understanding river flow dynamics. The findings leverage isotope hydrology techniques such as measuring stable isotopes in water molecules ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

Malnutrition manifests in various forms, from obesity and stunting to low weight for height, known as wasting. The World Health Organization (WHO) reports that undernutrition caused by several factors ...

The discovery of stable ''isotopes" began with J. J. Thomson's identification of neon-22 in 1912 (Bievre et al., 1984). More than 90 naturally occurring elements have been identified on the earth; ...
