The jury decision on awarding 2017 JINR Prizes for scientific, scientific-methodological, and scientific-technological applied researches was presented at the session of the Scientific Council.
An Encouraging Prize was awarded to V.A. Morozov (DLNP), N.V. Morozova (DLNP), and V.B. Zlokazov (LIT) for the series of works “Determination of scintillator decay time and study of spatial correlation of nuclear radiation by the autocorrelation method”.
We congratulate Dmitri Ponomarev and Alina Vishneva on successful presentation of their reports at the 123rd session of the JINR Scientific Council!
On 22–23 February 2018, the 123rdsessionoftheJINRScientificCouncilwasheld. On 23 February, by the recommendation of the PAC, reports were delivered by the young scientists working in our laboratory, winners of the PAC poster report sessions Dmitri Ponomarev, who spoke on the sensitive method for neutron detection using iodine-containing scintillators (http://indico.jinr.ru/getFile.py/access…), and Alina Vishneva, who spoke on the limit on the effective magnetic moment of solar neutrinos deduced from the Borexino data (http://indico.jinr.ru/getFile.py/access…). Our congratulations to Dmitri and Alina!
The DarkSide-50 experiment in operation at the Gran Sasso National Laboratories in Italy reported important new results on its search for dark matter, at the UCLA Dark Matter 2018 conference and at the Lake Louise Winter Institute 2018.
DarkSide-50 was designed as a search for high mass (>50 GeV/c2) Weakly Interacting Massive Particles (WIMPs) where the critical feature is background rejection. Analysis of a 530 day exposure has just been completed and the result is a convincing demonstration of the rejection capabilities of the technology. The discrimination achieved between natural radioactivity and nuclear recoils is a strong confirmation of the capabilities of the liquid argon technology. In addition to this achievement, a novel analysis of the ionization signal from low-energy events has been developed which demonstrates that the DarkSide-50 detector has outstanding capabilities in the search for lower mass (<10 GeV/c2) dark matter. These results encourage confidence that if a signal is eventually detected in a larger argon-based detector, like the upcoming DarkSide-20k, the signal will indeed be from something new in nature.
At DLNP, multidisciplinary investigations of genetic laws at the molecular level are being carried out using up-to-date instruments for the whole genome analysis of DNA and unique particle and radiation sources.
These investigations allow one to understand what kind of and how many mutations arise in DNA under the effect of radiation and what kind of radiation induces the largest changes in DNA. Mutations produced by ionizing radiation provide a lot of research material for studying the functioning of various genes and their regulation mechanisms, search for new regulation elements, and development of genetic-engineering structures with controlled gene functioning.
A possibility of working with both individual genes and whole genomes allows interesting experimental research to be conducted at JINR in the field of molecular genetics and radiobiology for studying the structure and functions of genes and the inherited changes in DNA resulting from the exposure to ionizing radiation.

In December 2017, DLNP purchased four Dell computing servers with Intel Xeon E5 processing units. The servers are already installed in the Laboratory of Information Technologies and will be used for simulation and analysis of the data from the Daya Bay and JUNO experiments within the LIT cloud infrastructure.
A new set of the Daya Bay data is prepared, which embraces the data-taking period of 1800 days and contains statistics of more than three million electron antineutrino interactions. Selection of events and statistical analysis of the extended data set will be performed by the DLNP group supported by LIT.
