University of Minnesota Cools Dark Matter Experiment to Near Absolute Zero

4/8/2026

Summary

Story summary

University of Minnesota scientists have cooled the Super Cryogenic Dark Matter Search (SuperCDMS) experiment at the Sudbury Neutrino Observatory Laboratory in Canada to just above absolute zero, enabling dark matter detection.
Dark matter is theorized to constitute about 85% of the universe's mass.
SuperCDMS will enable exploration of rare isotopes and new particle interactions.
The team will calibrate and optimize the detectors for months before operation.
