Mercury isotopic compositions of amphipods and snailfish from deep-sea trenches reveal information on the sources and transformations of mercury in the deep oceans. Evidence for methylmercury ...

Scandium-44 is a promising medical isotope for positron emission tomography (PET) imaging. PET allows doctors to measure the activity of the cells in the body to help identify cancer, heart disease, ...

Isotopic analysis primarily involves the separation of isotopes based on the significant differences in mass. The method is effective for identifying the isotopic signature within the inorganic and ...

A new electron microscopy technique that detects the subtle changes in the weight of proteins at the nanoscale -- while keeping the sample intact -- could open a new pathway for deeper, more ...
