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 ...

Brazil nuts are an especially nutrient-rich source of food: They contain important minerals like calcium and magnesium, essential amino acids and unsaturated fatty acids. Brazil nuts are characterized ...

Astatine is one of the least-studied elements of the periodic table, because all isotopes of astatine are unstable, with the longest half-life barely exceeding 8 hours. Thus, only radiochemists at the ...

The Rhisotope Project is embedding radioactive isotopes in the horns of rhinos in an effort to prevent poaching. Rhinos previously injected with the isotopes during Rhisotope's test phase turned out ...

MOKOPANE, South Africa (AP) -- A South African university launched an anti-poaching campaign Thursday to inject the horns of rhinos with radioactive isotopes that it says are harmless for the animals ...
