Ancient metallurgy has long provided critical insights into the technological and cultural evolution of past societies. In recent years, isotope analysis has emerged as a powerful tool in elucidating ...

With the new grant, the Stable Isotope Lab will acquire a cutting-edge instrument called an isotope-ratio-monitoring mass spectrometer (IRMS). A major grant from the National Science Foundation (NSF) ...

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 ...

Isotope dilution is used to determine the quantity of a chemical substance in a sample. In this method, isotopically enriched material is added to a sample which leads to a "dilution" of the standard.

Plants need phosphorus, an essential nutrient, to grow. This nutrient is present in fertilizers and applied to crops to increase their yields. One downside of too much phosphorus in this agricultural ...
