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 ...

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 ...

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, ...

Like everything we see in the world, isotopes are a type of atom, the smallest unit of matter that retains all the chemical properties of an element. Isotopes are forms of a chemical element with ...

If you’ve ever studied a periodic table of the elements (see below), you’re probably already aware that this table reveals a great deal about the chemical properties of the atoms that make up our ...

Separating different versions of elements—isotopes—is an excruciatingly difficult task: They differ by just one or two extra neutrons, an infinitesimal difference in mass. But University of Chicago ...

Light stable isotopes are widely used in forensic sciences (in the broadest sense) to determine habitats, biochemical processes, diets, the hydrological cycle, and climate change. The goal of this ...
