With great sadness, we share the news of the passing of Dr. Jan Kutner, our colleague and former PhD student. He was a dedicated researcher and a valued member of our scientific community. We extend our sincere condolences to his family and loved ones. (…)

How does Bacteroides fragilis adapt to the dynamic environment of the human gut? A newly published review paper by Daniel Ryan (IBB PAS) explores this question. Bacteroides fragilis employs a modular gene-regulatory network strategy to respond to its environment. Rather than relying on global regulators, it coordinates survival via modular switches such as DNA inversions, (…)

In the first half of October, two important scientific events took place at the Institute of Biochemistry and Biophysics PAS: IBB Day (October 7) and the IBB Scientific Session 2025 (October 8–10). This year’s IBB Day was more special than usual, as it was the final event of the Institute’s 70th anniversary celebrations. The program (…)

A new study reveals that the conserved ribosomal protein Rps29/uS14 links ribosome biogenesis with cellular stress adaptation. The results of this study, performed by Ulrike Topf’s team in collaboration with Rafał Tomecki at IBB PAS, were published in Nucleic Acids Research. The work describes that depletion of Rps29 disrupts the final cytoplasmic step of 18S (…)

The Board of Directors of the Institute, together with the Chairman of the Scientific Council, invite all employees, doctoral students and students of IBB PAS to “IBB DAY”, which will be held on October 7, 2025. The lectures will be held in Polish. For presentations and lectures, we invite you to the Conference Hall of IBiB (…)

Scientists from IBB PAS once again invite you to lessons and meetings as part of the 29th Warsaw Science Festival, which is lasting from Friday, September 19, until September 28, 2025. A detailed program is available at: http://www.festiwalnauki.edu.pl/ In total, IBB PAS has prepared 4 lessons and 3 festival meetings. (…)

IBB PAS co-organized ISSY38 in Warsaw, where yeast researchers from 36 countries met to share results. Two young IBB PAS scientists earned poster prizes. Last week was an exciting time for scientists working with yeast worldwide, as the 38th International Specialized Symposium on Yeasts (ISSY38): “Yeast – The Omni-Tool” was held here in Poland. The (…)

The Committee of Molecular Cell Biology of the Polish Academy of Sciences has awarded prizes and distinctions for publications from the year 2024. In the Prof. Kazimierz Bassalik competition for the best experimental work in the field of microbiology carried out in a Polish laboratory, the work of a team led by Dr. hab. Agata (…)

We are pleased to announce that Dr. hab. Tomasz Turowski (Laboratory of Transcription Mechanisms IBB PAS) and Prof. Christoph Engel (University of Regensburg, Germany) have been awarded a grant in the NCN Weave-UNISONO competition. Both teams will jointly pursue the project “Molecular mechanisms underlying the biogenesis of RNA polymerases I and III”. The aim of (…)

Researchers from the Institute of Biochemistry and Biophysics PAS and the International Institute of Molecular and Cell Biology have developed a new method for detecting RNA/DNA hybrids found in R-loop structures. R-loops are crucial nucleic acid structures that occur when a newly transcribed RNA molecule hybridizes with a complementary DNA strand. This process creates an (…)

A team led by Szymon Swiezewski from the Laboratory of Seed Molecular Biology at IBB PAS, in collaboration with the group of Artur Jarmołowski from Adam Mickiewicz University in Poznań, published an article in the journal Nature Communications. The work describes seed dormancy regulation by a new lncRNA MUSHER, which, in response to high temperature, (…)

During the 37th Annual Meeting of the Council of Managers of National Antarctic Programs (COMNAP), held in Warsaw on August 5–8, 2025, Agnieszka Kruszewska, Deputy Director of Administration at IBB PAS and Director’s Representative for the management of the H. Arctowski Station, was unanimously elected chair of COMNAP for the upcoming 3-year term. This distinction (…)
