A force that couples electrons and neutrons could be an addition to the Standard Model, and a new study places an upper limit ...

Isotopes, dinosaurs, and the redwood in the ravine. Isotopes are forms of an element that vary ever so slightly in their number of neutrons, leaving what you might call chemical ...

While the Standard Model (SM) describes all known fundamental particles and many of the interactions between them, it fails ...

Isotopes are atoms of the same element with the same number ... This is done using a two-step reduction, first with hydrogen, then with calcium. In short, enriching uranium is like trying to separate ...

Calcium isotope geochemistry examines the subtle variations in the 44Ca/40Ca ratio within ... Recent studies have further highlighted the interdisciplinary applications of calcium isotopes.
