While genetic tests can reveal the ancestry of enslaved individuals, strontium analysis can now home in on where they actually grew up.

The map is available for public use through open access. It is the first bioavailable strontium isotope map to show predicted strontium isotope ratios across all of Sub-Saharan Africa. Strontium ...

and the sum of the protons and neutrons gives the atomic mass, the number of neutrons defines the isotope of that element. For example, most carbon (≈ 99 %) has 6 protons and 6 neutrons and is written ...

The CUBES-SIL lab has three magnetic sector, gas-source, isotope ratio mass spectrometers designed to measure the relative abundance of stable isotopes of light elements and molecules. These ...

Unlike other stable isotopes, which require analysis on a species-by-species basis, deuterium signatures can be used to create a continental isotopic map, which is applicable to all migratory ...

Researchers mapped predicted bioavailable strontium isotope ratios across Sub-Saharan Africa. Matching values from the map against those observed in artifacts and plant, animal, and human remains will ...
