Magnesium isotope geochemistry has emerged as a fundamental tool for decoding the complex pathways of elemental cycling in marine environments. The isotopic composition of magnesium (commonly reported ...

A new experiment using rare-isotope beams has provided new insight into the origin of proton-rich isotopes known as p-nuclei.

Analysis of meteorite Erg Chech 002 shows that the radioactive isotope aluminum-26 was unevenly distributed in the early Solar System, overturning previous theories. (Yuri Amelin) A little over four ...

Krypton, the noble gas better known for its fictional association with Superman, has become one of the most telling chemical tracers in planetary science. By measuring krypton isotopes locked inside ...

A research team led by Prof. SHEN Yan'an from the University of Science and Technology of China (USTC) has made significant progress in studying the sources and formation mechanisms of haze. Through ...

Researchers measured very precisely atomic masses of radioactive lanthanum isotopes and found an interesting feature in their nuclear binding energies. The discovery provides essential data for ...
