Scientists just built a detector that could finally catch dark matter
Physicists have unveiled a new superconducting detector sensitive enough to hunt dark matter particles smaller than electrons. By capturing faint photon signals, the device pushes the search into uncharted territory.
Date: September 10, 2025 Source: University of Zurich Summary: Physicists have unveiled a new superconducting detector sensitive enough to hunt dark matter particles smaller than electrons. An international team led by Laura Baudis, Titus Neupert, Björn Penning and Andreas Schilling from UZH's Department of Physics has now been able to probe the existence of dark matter particles across a wide mass range below one mega electron volt (MeV). Using an improved superconducting nanowire single-photon detector (SNSPD), the researchers reached a sensitivity threshold of about one-tenth the mass of an electron, above which dark matter particles are highly unlikely to exist.
