When scientists have an interesting idea, the result is usually a joint publication. At the Institute of Nuclear Physics of the Polish Academy of Sciences in Cracow, it has been shown that tracking the dependencies between co-authors, one can not only see the paths along which scientific ideas flow, but also reconstruct the structure of scientific cooperation and detect emerging communities. Interestingly, the proposed method of analysis can be an effective tool to fight terrorists and... dishonest politicians.

The elementary particles of ‘new physics’ must be so massive that their detection in the LHC, the largest modern accelerator, will not be possible. This none- too-optimistic conclusion comes from the most comprehensive review of observational data from many scientific experiments and their confrontation with several popular varieties of supersymmetry theory. The complicated, extremely computationally demanding analysis was carried out by the team of the international GAMBIT Collaboration – and leaves a shadow of hope.

The Nuclear Physics European Collaboration Committee (NuPECC) has launched today its fifth Long-Range Plan (LRP 2017) for nuclear physics in Europe. This was marked formally at an event in the Brussels-based University Foundation. The event was attended by leading figures from the worlds of research, academia and European institutions.

There are too many high-energy positrons in the cosmic rays reaching the Earth. These positrons (particles that are antimatter equivalents of electrons) could be being produced by pulsars in our vicinity. The most recent measurements from the HAWC Observatory in Mexico have practically excluded this possibility, strengthening the competing and much more exotic hypothesis concerning the origin of the excess positrons.

Collisions of lead nuclei in the Large Hadron Collider (LHC) particle accelerator take place at such great energies that quarks that are normally confined inside nucleons are released and, together with the gluons that hold them together, form a stream of particularly exotic fluid: quark-gluon plasma. A new, more detailed theoretical model for this plasma, presented by a group of physicists from Poland and the USA, predicts that it has a much lower viscosity than previously estimated.
