What are Isotope Fingerprints? How can we detect an Isotope Fingerprint? Where can Isotope Fingerprints be applied? What are examples of applications of Isotope Fingerprints for food integrity, ...

Stable isotopes have helped uncover migratory routes, trophic levels, and the geographic origin of migratory animals. They can be used on land as well as in the ocean and have revolutionized how ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

Deep-sea microbes that “breathe” sulfur prefer that sulfur to be light. In fact, the microbes will “fractionate” heavier sulfur into lighter isotopes. Learning the preferences of these microbes can ...
