The precursors of heavy elements might arise in the plasma underbellies of swollen stars or in smoldering stellar corpses.

Potassium-Argon dating is similar to Carbon 14 dating because it uses radioactive decay, measuring the rate of change from an ...

Protecting water resources is an important goal for all countries, especially as we see the impacts of climate change becoming more and more pronounced. “Isotope hydrology is a really useful tool for ...

But the fusion reactors on Earth use deuterium and tritium, an unstable isotope of hydrogen that has two neutrons. Tritium has a half-life of around 12 years, and thus while it’s stable enough ...

But only one is stable and typically encountered: the naturally occurring gold that makes necklaces, rings and watches. Many unstable isotopes give off radioactive energy as they decay.

The International Atomic Energy Agency (IAEA), using isotope hydrology techniques, has pioneered a method to assess the contributions of different water sources to river flow in a new publication set ...

The isotopes of thulium, ytterbium and lutetium that the researchers created aren’t even the ones they’re really after. FRIB’s real goal is to go heavier.

Physicists studied nitrogen-9, an unusually high proton-to-neutron-ratio isotope, to check if it exists. Using a sophisticated setup, they bombarded an energised beam of oxygen-13 atoms at a ...

If you find an object with half as much carbon-14 relative to stable carbon isotopes as was in the historic atmosphere, it means it's 5,700 years old. A quarter as much means it's 10,400 years old.
