These are almost one-quarter of the periodic table and are mainly found in the first four periods. Of these, 11 are essential elements that our bodies need in larger amounts: oxygen, carbon ...

Where does the periodic table of chemical elements end and which processes lead to the existence of heavy elements? Researchers report on experiments to come closer to an answer. They gained insight ...

Axions: from soap to dark matter Protons, neutrons, electrons, photons -- most of us are familiar with the names of at least some of these tiny particles. The axion is lesser known, and for a good ...
