Perturbing electron spins in a magnet usually results in excitations called "spin waves" that ripple through the magnet like waves on a pond that's been struck by a pebble. In a new study, Rice University physicists and their ...

Dark matter does not emit or reflect light, nor does it interact with electromagnetic forces, making it exceptionally difficult to detect. Nevertheless, a research team from The Education University of Hong Kong (EdUHK) has ...

Our universe may feature large, macroscopic clumps of dark matter known as q-balls. These q-balls would be absolutely invisible, but they may reveal their presence through tiny magnifications of starlight.
