Stable isotopes are safe, non-radioactive forms of common elements such as carbon, nitrogen and hydrogen that occur naturally in small amounts in the foods and water we consume every day. Because they ...

An international study published in the Journal of Geophysical Research: Atmospheres has provided new insights into global ...

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 “workhouse” mass spectrometer can measure stable isotopes of purified organic tissues such as ... fossils, methane and hydrogen gas, & bulk organic matter, volcanic glass ...

In general, the lighter isotope of an element tends to be more abundant in nature – for example, 98.9% of the Earth’s carbon is 12 C, with 13 C making up the remaining 1.1%. Generally, stable isotope ...

The Austedo approval is notable for two reasons: One, it is the first deuterated drug (i.e., a drug containing the stable isotope — deuterium — in place of a hydrogen atom) to be approved by ...

Finding hydrogen’s footprints in cancer Hydrogen leaves a small ... now a research associate at the University of Colorado-Boulder Earth Systems Stable Isotope Lab. “So during the pandemic, I learned ...

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 ...
