From November 11 to 13, the LSC hosted the first workshop dedicated to Radon R&D&I, with a wide participation of experts and scientists. The objective of this meeting was to bring together the different groups working on research projects related to the Radon problem in Spain. The conferences promoted scientific exchange and underlined the importance of fostering new projects that generate knowledge and solutions for the benefit of society as a whole.

On November 7th, the director of Walqa and the mayor of Huesca welcomed the LSC to the Walqa ecosystem, Huesca’s technology park, where the LSC has established a new logistics center. At this center, the PMT covers of the Hyper-Kamiokande experiment will be stored and undergo quality control before being shipped and installed in Japan in 2026.

On November 5th and 6th, the 35th meeting of the LSC Scientific Advisory Committee took place. The Committee heard presentations from the DArT, BabyIAXO, TREX-DM, and NEXT experiments and reviewed written reports from the other experiments. In addition, researcher Juan José Gómez Cadenas (DIPC) shared the future plan for the NEXT experiment, which includes the development of NEXT-HD: a TPC with 1 ton of enriched xenon, designed for the search for neutrinoless double beta decay.

During the week of October 7th, the first experiment with vertebrates was conducted at the LSC, led by researcher Laia Ribas, one of the crew members of the Hypatia I project. The aim of the experiment is to study the impact of microgravity and the absence of radiation on two species: zebrafish, a key model in biomedical research, and sea bass, a species commonly used in aquaculture. The results of GraCosFish will bring us closer to the possibility of raising fish in space.

Iván Coarasa, a researcher from the University of Zaragoza and a member of the ANAIS collaboration, has presented the results after 6 years of data taking on the dark matter signal modulation with ANAIS. The results show an incompatibility with the DAMA/LIBRA signal at nearly 4σ. ANAIS-112 is leading international efforts in the search for this signal in a model-independent way, with a projected sensitivity of 5σ by the end of 2025.

Next Sunday 27th October, we invite you to discover the Canfranc Underground Laboratory with activities for the whole family. Free entry! Enjoy: · Museum Room visits · Experimental Workshops · Workshops for Kids We look forward to seeing you from 11 am to 2 pm! Don't miss it!

After 6 months at the LSC, the first experiment with Sphaeroforma arctica, a single-celled organism related to animals, has been completed. The objective of this group is to study the origin of multicellularity, and for this purpose, the growth and morphology of both above and underground cultures have been evaluated. In the next phases, genetic analysis of frozen samples will be carried out to deepen our findings. We continue to make progress!

Pipo Bayo and Beatriz Hernández reunited with the students who participated in the 1st LSC Scientific Classroom for ESO students in 2023. The event took place on October 3rd at IES Elisa y Luis Villamil in Vegadeo (Asturias). During the session, they gave a talk on the origin of matter in the Universe and led a hands-on activity on natural radiation.

The Low Radioactivity Techniques (LRT2024) workshop was held in Krakow (Poland) from 1 to 4 October. The aim of this workshop is to present and discuss low-radioactivity techniques and materials that are fundamental for rare-event experiments. Our colleagues Laura Cid and Silvia Borjabad presented the latest developments and results of the ‘Mass Spectrometry (ICP-MS)’ and ‘Copper Electroforming’ services of the LSC.
