An international team of scientists, including Aleksander Augustyn, a fourth-year doctoral student at the Doctoral School of the National Centre for Nuclear Research, has directly observed the exceptionally rapid alpha decay of tellurium-104 for the first time. The results of the study, published today in the prestigious journal Nature, show that this unstable atomic nucleus decays in a matter of nanoseconds. Tellurium-104 is the fastest known alpha emitter from the ground state.

Due to their high strength and thermal stability, refractory complex concentrated alloys (RCCA) can be used in applications where components are exposed to extreme conditions. However, a thorough understanding of their properties and behavior during operation is necessary before they can be implemented. A team of scientists from the NOMATEN Centre of Excellence and Materials Research Laboratory at NCBJ combined experimental methods with computer simulations to study the MoTaW alloy.

Scientists from the National Centre for Nuclear Research (NCBJ) have investigated the properties of a new scintillation material that could be used in advanced radiation detectors capable of simultaneously distinguishing between several types of radiation. The research results were published on 26 March 2026 in the international journal *Journal of Instrumentation* (DOI: 10.1088/1748-0221/21/03/P03049).

An international team studying data from NASA’s Fermi Gamma-ray Space Telescope concludes the mission detected a rare, unusually luminous supernova. The researchers say it likely received its power-up from a supermagnetized neutron star born in the stellar collapse that triggered the explosion. An astrophysicist from the National Centre for Nuclear Research took part in the project.

A meeting was held at the National Centre for Nuclear Research between NCBJ representatives and Prof. Kirk Atkinson from Ontario Tech University — one of Canada’s leading universities developing expertise for the nuclear energy sector and SMR technologies. The meeting was a planned return visit by the Canadian delegation to Poland, following last year’s meeting involving NCBJ representatives at OTU laboratories.

An international team of scientists has conducted the most precise measurements to date of CP symmetry breaking in hyperon decays. Researchers from the National Centre for Nuclear Research (NCBJ) — dr Varvara Batozskaya and Prof. Andrzej Kupść — made key contributions to the analysis.

An international team of researchers, including dr Krzysztof Hryniewicz of the National Centre for Nuclear Research, has developed a new model describing the hot gas surrounding the supermassive black hole in the active galaxy Mrk 509. The findings help to better understand the structure of matter in the vicinity of active galactic nuclei.

The energy transition is increasingly shifting from the realm of political declarations to the world of concrete technologies, precise definitions, investments, and industrial implementations. The director of the National Centre for Nuclear Research (NCBJ), who has assumed the role of Chair of the CIRE PowerUp Programme Council, is among the experts who combine scientific expertise with a practical perspective on the development of the energy sector. This is a clear signal that the voice of the NCBJ and nuclear energy are an indispensable part of the debate on the energy transition.

In the world of the energy industry and critical infrastructure, laboratories are increasingly becoming the birthplace of technologies of strategic importance. Representatives from the National Centre for Nuclear Research (NCBJ) and PERN S.A. discussed how science can support business at the National Centre for Nuclear Research. The programme for the visit included, amongst other things, presentations on research infrastructure and discussions on the potential for cooperation between the scientific and industrial sectors.

An international team of researchers, including Prof. Marek Biesiada of the National Centre for Nuclear Research and dr Aleksandra Piórkowska-Kurpas of the University of Silesia in Katowice, has conducted one of the most precise studies to test the so-called weak equivalence principle — a cornerstone of Albert Einstein’s general theory of relativity.
