More bad news for controversial 20-year-old claim of dark matter detection

Over 20 years ago, a team running an underground experiment in Italy announced that it had detected evidence of dark matter—a claim the collaboration maintains to this day. Housed deep underground in South Korea, COSINE-100 also uses detectors made of sodium iodide crystals, and is large and sensitive enough to hunt for the same dark matter signal supposedly detected by DAMA/LIBRA. The results: “We didn’t find dark matter, and we discovered that the DAMA/LIBRA measurements aren’t consistent with the standard model for the dark matter halo,” said co-author Nelson Carlin Filho of the University of Sao Paulo in Brazil.
