“One [goal] was to look at the soil biology, see what is interacting with the phytate. The other was to explore and track oxygen isotopes in phytate using the Orbitrap IRMS.” The researchers incubated ...

Isotopes are versions of an element that differ in their atomic weights. For example, most oxygen atoms contain eight protons and eight neutrons and are represented by the symbol O-16.

The neutron-rich oxygen isotopes oxygen-27 and oxygen-28 exist as very short-lived resonances, report scientists based on the first observation of their decay into oxygen-24 and three and four ...

AMES, Iowa – The Earth of 3.2 billion years ago was a “water world” of submerged continents, geologists say after analyzing oxygen isotope data from ancient ocean crust that’s now exposed on land in ...

The paper, titled Distinct oxygen isotope compositions of the Earth and Moon, may challenge the current understanding of the formation of the Moon. Previous research led to scientists to develop ...

Isotopes of hydrogen and oxygen can also be used to date and study the movements of water, since water is made up of these two elements. For example, by comparing the ratio of certain oxygen isotopes ...
