Relativity matters: Two opposing views of the magnetic force reconciled
Our understanding of how a point-particle carrying a charge moves in presence of an inhomogenous magnetic field relied until now on two theories that were believed to differ. In a new study just published in EPJ C, the authors Johann Rafelski and colleagues from the University of Arizona, USA, succeeded in resolving this ambiguity. Their solution makes it possible to characterise the interaction of particles whose speed is close to the speed of light in the presence of inhomogeneous electromagnetic fields. (2018-01-29)

Cosmic x-rays may provide clues to the nature of dark matter
Researchers at Johannes Gutenberg University Mainz in Germany have presented a novel theory of dark matter, which implies that dark matter particles may be very different from what is normally assumed. In particular, their theory involves dark matter particles which are extremely light -- almost one hundred times lighter than electrons, in stark contrast to many conventional models that involve very heavy dark matter particles instead.

Leptons help in tracking new physics
Electrons with 'colleagues' -- other leptons - are one of many products of collisions observed in the LHCb experiment at the Large Hadron Collider.
