Strings of giant’s beads are being carefully submerged into the dark water of the deepest lake on Earth. Pulled out, they cover a distance of more than a kilometre. Even the Ostankino TV Tower would seem to be a dwarf near these self-floating units. Thick cables reach the shore: the neutrino observatory hunts after the most elusive particles in the Universe born in distant space accelerators.

We quote the article author Ilya Batsaev, “Scientists across the world go on arguing about how a subnormal level of radiation changes activity of human genes and what is the lower threshold of its harmful impact. Researchers of the Dzhelepov Laboratory of Nuclear Problems of the Joint Institute for Nuclear Research from Dubna, together with colleagues from the Baksan Neutrino Observatory, performed the Russia’s first experiment on the impact of the low radiation level on living organisms. The result invalidates all previous theories of foreign colleagues.”

Впервые в России в условиях уникальной подземной низкофоновой лаборатории Баксанской нейтринной обсерватории ИЯИ РАН проведены биологические исследования по оценке влияния пониженного радиационного фона на сложные модельные организмы. В качестве модели был использован классический объект генетических исследований — плодовая мушка Drosophila melanogaster. Проведенный эксперимент показал отсутствие влияния пониженного радиационного фона на этот модельный организм.

What microorganisms, capable of making the soil and atmosphere composition suitable for life, can be settled and where

 

Scientists have spotted the areas on Mars where colonies of lichen and autotrophic bacteria (organisms capable of synthesizing organic matter from inorganic one) can be settled. Microorganisms will be protected from temperature differences, strong wind and hard ultraviolet radiation in the Valles Marineris and in the Hellas Planitia located near the equator. They can multiply there and transform Mars with time making it suitable for life and colonization. Experts believe that it is reasonable first to make the conditions on the neighbouring planet milder, and only then to settle microorganisms there in order to finally transform the appearance of Mars.

The article about the Baikal Neutrino Telescope “Where do neutrinos come from?” by the researcher of the DLNP Experimental Department of Nuclear Spectroscopy and Radiochemistry Rastislav Dvornicki was published in the Science section of the August issue of the S7 airline inflight magazine.

Rastislav describes clearly and interestingly in the short article the neutrinos’ nature and functioning of the complex physics facility. The photographs from Lake Baikal by his colleague Bair Shaybonov illustrate the subject matter.

Neutrinos and neutrino physics are one of the “hottest” topics in explaining fundamental science to the general audience. And this is mainly owing to such articles by our researchers.

Один из наиболее интригующих вопросов современной физики — почему во Вселенной больше материи, чем антиматерии. Ответ может скрываться в понимании природы нейтрино: в одной из главных теоретических моделей эта частица идентична своей античастице. Если так, то становится возможным редчайший ядерный процесс, называемый двойным безнейтринным бета-распадом (0).

The interview with Dmitry Naumov (DLNP Deputy Director) and Elena Dubovik (DLNP SciCom Group) about the DLNP Group of Scientific Communication and science communication in general was published in the weekly newspaper “Dubna: Science, Community, Progress”.


On 8 September, the seminar “Group of Scientific Communication: Share Knowledge, Explain What is Going On, Keep the History” was held at the Dzhelepov Laboratory of Nuclear Problems. The DLNP Deputy Director of Science Dmitry Naumov led the seminar. The head of the Group Elena Dubovik talked about the results gained after one and a half years of work, about ongoing and upcoming projects. Later, Igor Ivanov, a noted science educator, theoretical physicist, DLNP researcher, joined the discussion. Since the questions were asked mostly by DLNP staff members, the weekly decided to ask the Group to tell us in more detail about their activities. We hope that this experience will be helpful to other JINR subdivisions.

Российские ученые разработали гибридный материал на основе пластика и редкоземельного металла гадолиния. Полученный материал сам не обладает радиоактивным фоном, но при этом может фиксировать и поглощать постороннее излучение. Эти уникальные свойства позволяют использовать его для изготовления оболочек детекторов для обнаружения частиц темной материи. Результаты работы опубликованы в журнале Materials. Материал предназначен для эксперимента по обнаружению темной материи DarkSide 20K, который планируют запустить в Италии в 2025-2026 годах.

— Уникальное микробное сообщество мы привезли из сверхглубокого подземного тоннеля Баксанской нейтринной обсерватории на Северном Кавказе, — рассказывает Елена Кравченко, кандидат биологических наук, начальник Сектора молекулярной генетики клетки Лаборатории ядерных проблем им. В.П. Джелепова Объединенного института ядерных исследований (ОИЯИ). Этот институт уже больше 60 лет работает в подмосковной Дубне.
