Isotope results from the Middle Neolithic reveal that sheep were likely grazing on the shore and that humans relied on a diet ...

The Center for Isotope Geochemistry is a world-class facility for high-precision analysis of both radiogenic and stable isotopes on a wide range of materials. The Center is spread over two ...

The application of Stable Isotopes measurements can be used to integrate, indicate, record and trace fundamental ecological processes. Rapid technological advances over the past decade have greatly ...

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 ...

A potential problem is that nitrogen is a building block of proteins and therefore may succumb to protein catabolism occurring during migration, which can cause increased nitrogen isotope ...

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 ...

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3 He) emitted from the sun. A Southwest Research Institute-led team of scientists sought the ...

Stable isotope techniques are useful for the evaluation of food fortification programmes or dietary diversification strategies. Protein bioavailability from plant foods to maintain and optimize the ...

Stable isotopes are non-radioactive forms of atoms. Although they do not emit radiation, their unique properties enable them to be used in a broad variety of applications, including water and soil ...
