Invisible sheetlike structures, which might pervade space and contribute to dark matter or dark energy, could be revealed as they pass by Earth-based detectors.

Three major drawbacks to the ΛCDM dark matter model of the universe may be ameliorated if a proposed particle couples to dark matter and to neutrinos.

A new analysis shows that it is possible to look for dark-matter particles with mass far below 1 giga-electron-volt by using atomic ionization.
