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 ...

Some atoms are stable, while others seem to fall apart. Lead-208 will probably last forever, while the synthetic isotope technetium-99 exists for ... are spontaneously emitted from heavier, unstable ...

Stable isotope analyses of tissues have been used to help delineate natal regions and routes of migratory animals. The foundations of such studies are isotopic gradients or differences representing ...

The U.S. Department of Energy is investing an additional $527 million into a cutting-edge isotopes research facility at Michigan State University, where scientific breakthroughs are coming ever more ...

Radioactive decay is a fundamental process in nature by which an unstable atomic nucleus loses energy by radiation. Studying nuclear decay modes is crucial for understanding properties of atomic ...

Scientists may have just caught their first glimpse of an ultra-rare version of nitrogen containing five more protons than it can stably hold. Scientists discovered hints of the new isotope, called ...

A new study uses carbon isotope science to show that marked tusks in a seized ivory shipment were more than 30 years old and likely had found their way from a guarded government stockpile into the ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Our Universe is old: 13.8 billion years old, to be precise. Many of the ...
