Misha lived her whole life in zoos, but this elephant’s teeth are now helping scientists reconstruct wildlife migrations. University of Utah geologists show how strontium isotopes found in teeth or ...

At the BIG we use Sr/Ca as a proxy for dietary intake and Sr isotopes as a proxy for transhumance and migration. Strontium isotopes that vary with the underlying geology are incorporated into teeth ...

Oelze and her team focused on the isotopes strontium 86 and 87, which show up in the ancient bedrock of Angola. (A quick refresher from chemistry class: Isotopes are variations of an element that ...

A sophisticated new map of Africa, using a little-known element, helps reveal where rare animals exploited by the illegal ...

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 ...

This space is also home to two IsotopX Phoenix Thermal Ionization Mass Spectrometers. These TIMS’ were installed in 2016 and 2022 and are primarily used for high-precision analysis of small sample ...

For the first time, scientists have directly measured a weak r-process reaction using a radioactive ion beam, shedding light ...

"Our study not only adds to our understanding of how tooth enamel records an animal's Sr isotope exposure, but also helps to reconstruct animal migrations from Sr isotope analysis," lead author ...
