On the evening of 26th September, researchers from LSC travelled to Huesca and Zaragoza to participate in the European Researchers' Night. Through workshops on cosmic rays and radioactivity, mass spectrometry and copper electroforming, as well as a new workshop on biology from home, the attendees were able to learn more about the science behind the laboratory. We hope you enjoyed it as much as we did!

On July 31, 2025, the Hyper-Kamiokande collaboration completed the excavation of the colossal cavern that will house the main detector volume of Hyper-Kamiokande, a next-generation ultra-pure water Cherenkov detector currently under construction in the city of Hida, Gifu, Japan.

A few weeks ago, we successfully completed a new hydrostatic test campaign to validate the protective covers for the sensors of the future Hyper-Kamiokande (HK) neutrino telescope. A team from the LSC traveled to the ITP facilities in Mòra d'Ebre (Tarragona) and tested 12 covers: two of them with acrylics aged with temperature and humidity to simulate transport to Japan, and another two submerged in water to study the effects of absorption on the final system. Another step forward for the LSC in this great international Project.

Last Friday 4th July we had the pleasure of receiving a visit from the children taking part in the summer camps organized by ONCE (Spanish National Organisation for the Blind), which this year focused on Science. During their time at the LSC, our outreach team offered them an introductory workshop about the fascinating world of neutrinos and the detection techniques used in low-background experiments. The day ended with an exciting tour of our underground facilities. Thank you for coming and sharing your curiosity with us!

The first article from the collaboration of researchers involved in the heavy water bacteria experiment at the Canfranc Underground Laboratory (LSC) has recently been published. This publication presents the first identification of bacterial communities capable of evolving in an environment considered hostile for most organisms.
