A new forensic test could help identify poached elephant ivory being disguised and smuggled as legal mammoth tusks.

One of the most abundant elements on our planet and in the human body is oxygen, in particular the isotope oxygen-16. With eight protons and eight neutrons, oxygen-16 has an extremely stable nucleus.

Stable isotope analysis could offer a new tool in the fight against wildlife poaching by helping differentiate legal mammoth ...

Demand for the ornaments, jewelry, and other luxury items carved from the ivory in elephant tusks has led poachers to ...

Wildlife forensic experts have developed a new approach to distinguishing between legal mammoth ivory and illegal elephant ...

They measured multiple types of sulfur isotopes from cores drilled into the rocks. “What we got was really cool and a little bit surprising,” he says. The sulfur isotopes showed several fluctuations ...

This measurement provides carbon, oxygen and “clumped” isotope ratios for carbonate minerals, which enables us to reconstruct the temperature at which the carbonate formed, along with information ...

Oxygen isotopes. Now, Paltiel and colleagues have shown that nuclear spins are also relevant to CISS. The researchers set up two experiments involving three stable isotopes of oxygen. These are oxygen ...

Stable isotopes are isotopes of chemical elements that do not undergo radioactive decay or are not susceptible to radioactive decay. ... Oxygen-18 (18O ) is a natural, stable isotope of oxygen and one ...

One of the most abundant elements on our planet and in the human body is oxygen, in particular the isotope oxygen-16. With ...

Earth's First Stable Dose of Oxygen Nearly Ended All Life The Great Oxidation Event likely went on for 100 million more years than scientists previously thought and it wasn't so stable after all. By ...
