Whether primordial black holes really do account for dark matter in the universe is still up for debate. Among the astronomical community it is generally accepted that they cannot account for all dark matter but probably account for up to 10% of dark matter in the planetary mass range Whether this is PBHs account for any of the dark matter in the universe requires further analysis.
In a paper published by Badal Bhalla from the University of Oklahoma and a team of astronomers they explore the way PBHs can lose energy when interacting with stellar binary systems. These interactions can result in any one of 5 possible outcomes;

Using small black holes to detect big black holesAn international team of astrophysicists with the participation of the University of Zurich proposes a novel method to detect pairs of the biggest black holes found at the centers of galaxies by analyzing gravitational waves generated by binaries of nearby small stellar black holes. The research is published in the journal Nature Astronomy.
