Summary

Story summary

The QROCODILE experiment, led by the University of Zurich and Hebrew University of Jerusalem, seeks to detect light dark matter.
It employs superconducting detectors cooled to near absolute zero, achieving sensitivity to energy deposits as low as 0.11 electron-volts.
During a 400-hour run, the experiment recorded unexplained signals, setting new limits on dark matter interactions.
Future upgrades will improve signal directionality detection, aiding in distinguishing dark matter from background noise.
The NILE QROCODILE phase will move the experiment underground to minimize cosmic ray interference.
