PROF. SODDY'S letter in NATURE of February 4 would seem to lead to certain interesting conclusions about the structure of the atom. It is easy to show that two elements of different atomic weight must ...

Scientists have measured the half-lives of five never-before-seen isotopes in a first demonstration of a research facility that will help probe the nuclear structures of elements (Phys. Rev. Lett.

Researchers using the KEK Isotope Separation System (KISS) in Japan have created a new isotope of uranium with 149 neutrons to go along with the element’s 92 protons (Phys. Rev. Lett. 2023, DOI: ...

Millicurie quantities of 14 C do not present a significant external exposure hazard because the low-energy betas emitted barely penetrate the outer skin layer. The critical organ for uptake of many 14 ...

Astronomers at Leiden University have detected rare isotopes of carbon and oxygen in our neighboring stars for the first time, providing a new path toward better understanding the chemical evolution ...

A constant rain of tiny meteorites kicks up dust on the moon and helps generate the thin layer of atoms that form its exosphere. The moon doesn't have an atmosphere like the one that shields Earth ...
