Data acquisition starts at the JUNO experiment

On 26 August 2025, the international collaboration of the JUNO experiment officially announced the completion of filling the central detector with 20 thousand tonnes of liquid scintillator at the Jiangmen Underground Neutrino Observatory on the south of China. The collaboration also started the detection of physical events. The aim of the experiment is determination of the hierarchy of neutrino masses and precision measurement of neutrino oscillation parameters.

Long term remote reactor power and fuel composition monitoring using antineutrinos

In July 2025, a new paper titled "Long term remote reactor power and fuel composition monitoring using antineutrinos" was published in Physics Letters B. It presents the results of seven years of antineutrino flux measurements from a nuclear reactor at the Kalinin Nuclear Power Plant in the DANSS experiment. DLNP staff members play a key role in the experiment, ranging from the development of the first detector prototypes to ensuring the described long-term measurements at the Kalinin NPP.

Comparative analysis of enriched mesenchymal stem cells conditioned medium fractions obtained by ultrafiltration

The July-September 2025 open-access issue of the Natural Science Review journal featured an article by researchers from JINR, Lomonosov Moscow State University, and the National Medical Research Center for Rehabilitation and Balneology. The article presents a comparative analysis of various components produced by mesenchymal stem cells into the conditioned medium, obtained using serum-based and serum-free culture methods and isolated via ultrafiltration techniques.

“It is a great honour for me to receive the V. P. Dzhelepov Scholarship”

This year Elena Sergeevna Kurakina has been awarded the V. P. Dzhelepov Scholarship. The Group of Scientific Communication asked Elena Kurakina about her work, experiments and plans for the upcoming scholarship year.

“Dzhelepov for me is an example of the scientist who not only pursued science but also created conditions for it to develop over decades”

This year Vladislav Andreevich Rozhkov became the laureate of the V. P. Dzhelepov Scholarship. The Group of Scientific Communications asked Vladislav about his work at the laboratory, scientific achievements, and plans for the future.
