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

Poachers are using a sneaky loophole to bypass the international ivory trade ban—by passing off illegal elephant ivory as ...

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

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

A new tool to detect elephant tusks disguised as legal mammoth ivory has been deployed in the battle against poaching. Stable ...

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 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 ...

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 ...
