Scientists have created a groundbreaking map of strontium isotopes found across sub-Saharan Africa—which could help ...

Ancient pollen, silicified plant remains, known as phytoliths, and leaf wax isotopes from site sediments ... such as this is vitally important in being able to further study the history and evolution ...

While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in nutrition research, nitrogen-15 is the most common stable isotope used in agriculture. Many other stable isotopes ...

before being introduced into a mass spectrometer for identification and analyses. With standard single quadrupole GC/LC-MS, accurate detection of isotopic abundance is limited to ∼0.1 atom percent ...

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 ...
