A new tool in search for axions
Researchers from the international BASE collaboration at CERN, Switzerland, which is led by the RIKEN Fundamental Symmetries Laboratory, have discovered a new avenue to search for axions-a hypothetical particle that is one of the candidates of dark matter particles. The group, which usually performs ultra-high precision measurements of the fundamental properties of trapped antimatter, has for the first time used the ultra-sensitive superconducting single antiproton detection system of their advanced Penning trap experiment as a sensitive dark matter antenna.
If our current understanding of cosmology is correct, ordinary “visible” matter only makes up 5 percent of the total energy content of the universe. Another 26 percent is believed to be a mysterious substance called “cold dark matter”. Because this hypothetical “dark matter” does not interact strongly with ordinary matter, it is extremely hard to detect, and as a result it

An international research team succeeded in gaining new insights into the artificially produced superheavy element flerovium, element 114, at the accelerator facilities of the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. Under the leadership of Lund University in Sweden and with significant participation of Johannes Gutenberg University Mainz (JGU) as well as the Helmholtz Institute Mainz (HIM) in Germany and other partners, flerovium was produced and investigated to determine whether it has a closed proton shell. The results suggest that, contrary to expectations, flerovium is not a so-called magic nucleus . The results were published in the journal
