No dark matter detected
Physicists from the GNOME collaboration did not detect particles
of axionic dark matter after analyzing data collected during the
second season of the global network of magnetometers. The results
of the analysis, however, allowed the researchers to set limits on
the mass of particles of axionic dark matter and the constant of its
interaction with ordinary matter. Scientists expect that the ongoing
modification of the network of detectors will help significantly
increase the accuracy of the experiment. The research is published
in Nature Physics (

The hypothesis that about 80% of the mass of all matter in the
Universe is invisible dark matter explains many astronomical
observations: both the anomalously high speeds of stars at the
periphery of galaxies and galaxies at the periphery of galactic
clusters, and the exact shape of the spectrum of inhomogeneities
in the temperature of the cosmic microwave background ... Despite
convincing evidence in favor of the existence of dark matter, not a
single ground-based experiment has succeeded in registering the
particles of which it is composed.
