Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This ...

Potassium isotope compositions of minipig brain regions indicate heavy K isotope enrichment coincident with amyloid beta accumulation, suggesting a mechanistic linkage and potential for downstream ...

In nuclear physics so-called magic number are such nuclear proton and/or neutron numbers, for which the nucleus is more stable compared to neighboring isotopes on the nuclear chart. Researchers in ...

Here’s what you’ll learn when you read this story: Our Earth as we know it had a “proto-Earth” phase that didn’t survive long before it was pummeled by an asteroid. Researchers who compared levels of ...

Measuring the size of atomic nuclei has sometimes been useful to probe aspects of nucleon-nucleon interaction and the bulk properties of nuclear matter. The charge radius of atomic nuclei, which can ...

Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium ...

The lunar basalts brought back by China's Chang'e-6 mission carry an unexpected chemical signature. Their potassium isotopes are noticeably heavier than those from Apollo mission samples or lunar ...

The Potassium Decay (KDK) Collaboration used the KDK array to detect a previously unmeasured process in the radioactive decay of potassium-40 to argon-40 involving a rare type of electron capture.
