A research team led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has discovered ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

An atom in which both the protons and the neutrons ... 208 Pb is the heaviest known stable isotope of any element; as such, it's considered an important cornerstone of nuclear physics, and key ...

Living organisms need nitrogen as a central building block for protein formation, for example. However, although our ...

New research reveals that hydrothermal vents provided early Earth with abundant nitrogen, challenging previous theories.

Einsteinium-255, produced through irradiation in ILL’s high-flux reactor, provided a continuous supply of fermium-255, ...

In heavy water, each hydrogen atom is indeed heavier, with a neutron as well as a proton in its nucleus. This isotope of hydrogen is called deuterium, and heavy water's more scientific name is ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...

This Section implements all activities of the IAEA's Water Resources Programme, which promotes and transfers know-how on the use of isotope hydrology as an effective tool for water resources ...

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 ...
