At first, Professor Glen Jackson, who teaches forensic and investigative science at West Virginia University, had a hard time explaining to me what isotopes are. He told me he is used to speaking with ...

Isotope analysis, and in particular compound‐specific stable isotope analysis (CSIA), has emerged as an indispensable tool in the investigation of environmental biodegradation. By measuring the subtle ...

Archaeologists at UC Santa Cruz used predictive modeling to map strontium isotope ratios across all of modern-day Angola, a region in Southwest Africa that was once a major hub for the transatlantic ...

Carbon isotope analysis is an analytical method that quantifies the relative abundance of stable carbon isotopes, primarily ¹²C and ¹³C, in a sample to infer biogeochemical processes, sources, and ...

Demand for the ornaments, jewelry, and other luxury items carved from the ivory in elephant tusks has led poachers to decimate elephant populations. An international ban exists on the ivory trade, and ...

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 ...

The researchers’ forensic tool uses stable isotope analysis to identify the carbon and nitrogen values that reflect the differences in the diets of birds raised in captivity and those from the wild.

Isotope analysis reveals that social status and wealth had a profound impact on diet in medieval England, showing that people from different social groups in medieval Cambridge ate markedly different ...

Sometime around 660 CE, silver coinage replaced gold as the dominant form of currency in northwest Europe. But what was the source of all that silver? According to a recent paper published in the ...
