In the continuing game of dark matter hide-and-seek, new results from two experiments have helped the collaborations behind them rule out further hiding places for the elusive substance [1, 2]. The results come a year after the team behind another dark matter experiment reported tantalizing signals that could be interpreted as evidence for a hypothesized dark matter particle called an axion (see Viewpoint: Dark Matter Detector Delivers Enigmatic Signal). With neither of the new results indicating the existence of dark matter, the collaborations behind both experiments are now looking to expand their searches and further tighten constraints with future campaigns.
