What does this achievement mean for you and how will it influence your next steps?</strong></h5><p>Thank you. It’s&nbsp;a huge achievement to receive this prestigious grant. It gives me the opportunity to establish my own research group here at UCT Prague. The JUNIOR STAR program supports talented young scientists in building their teams and accessing resources. This means I&nbsp;now have the support to focus fully on my research about tubular MXenes and their application in supercapacitors.</p><h5><strong>Why are tubular MXenes so innovative for energy storage?</strong></h5><p>MXenes are a family of 2D materials with a layered, accordion-like structure and known for their excellent electrical conductivity. Our innovation is to produce them with a tubular morphology, combining the high conductivity and redox activity in superior ion-transport tubular architectures. Their open, hollow structure increases surface area, ion diffusion and charge transport. This could translate to faster, more efficient supercapacitors, critical for sustainable energy technologies.</p><h5><strong>How did your scientific interest lead you to this field?</strong></h5><p>Global challenges around green energy made me focus on materials that can improve energy storage. MXenes stood out because changes in the composition and structure can significantly change their properties. I&nbsp;was curious about how tuning different metallic elements in a&nbsp;tubular morphology can impact how MXenes perform and how to optimize them for practical applications.</p><h5><strong>What challenges have you encountered?</strong></h5><p>One major challenge is their stability: MXenes oxidize quickly which deteriorates performance. Another challenge is understanding how synthesis conditions of both MXenes and their precursors (MAX phases) must be adapted to create and preserve tubular morphologies since their synthesis mechanisms differ from conventional MXenes. Additionally, effectively communicating the project in the funding proposal to show to reviewers why I&nbsp;should obtain this funding was also a&nbsp;challenge, but thanks to mentorship and collaboration, I&nbsp;overcame these hurdles.</p><h5><strong>What motivates you most about working at UCT Prague?</strong></h5><p>The support from colleagues and the excellent technical infrastructure make it a&nbsp;great place to work. Also, being a&nbsp;former member of Professor Sofer’s&nbsp;leading group in 2D&nbsp;materials is inspiring and led me to this achievement.</p><h5><strong>How do&nbsp;you see your professional development going in the future?</strong></h5><p>The grant will help me build my own team, acquire equipment, and develop collaborations. My long-term vision is to contribute significantly to sustainable energy solutions and scientific progress both locally and internationally.</p><h5><strong>You are looking for new team members. What kind of students or scientists do&nbsp;you need?</strong></h5><p>We are currently welcoming enthusiastic master's&nbsp;students, PhD candidates, and postdocs who are passionate about materials science and eager to explore new frontiers in MXenes and energy storage. If you love curiosity-driven research and want to be part of a&nbsp;growing international team, we encourage you to join us.</p><h3><strong>Interview with Stella Gonsales: Catalysis as a&nbsp;key to polymer recycling</strong></h3><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/VSCHT_Praha_V_prestizni_soutezi_GACR_uspely_dve_zahranicni_vedkyne_z_VSCHT_3_3d0ded6274.jpeg" alt="VŠCHT Prague: JUNIOR STAR Grants at UCT Prague: Two talented women from abroad driving innovation in science: Stella Gonsales" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_VSCHT_Praha_V_prestizni_soutezi_GACR_uspely_dve_zahranicni_vedkyne_z_VSCHT_3_3d0ded6274.jpeg 233w," sizes="100vw" width="1499" height="1000"></p><h5><strong>Congratulations on your JUNIOR STAR grant and also being awarded the Dagmar Procházková Fund. What does receiving both mean to you and how will they shape your work?</strong></h5><p>Thank you. Both grants are hugely important. The JUNIOR STAR grant allows me to expand my group and resources for research into catalytic recycling of polymers, while the Dagmar Procházková Fund supports complementary projects such as synthesizing new biodegradable polymers. Together, they help tackle the plastic waste problem from multiple scientific angles.</p><h5><strong>Could you explain your research in layperson’s&nbsp;terms?</strong></h5><p>Most plastics have strong carbon-carbon bonds. We insert more cleavable double bonds into polymers that can be broken down by catalytic reactions called olefin metathesis, making recycling on a&nbsp;molecular level more feasible.</p><h5><strong>What makes the JUNIOR STAR grant particularly important for your research and career development?</strong></h5><p>The JUNIOR STAR grant is a&nbsp;prestigious and highly competitive funding opportunity aimed at excellent early-career scientists within eight years of completing a&nbsp;Ph.D. It provides up to 25&nbsp;million CZK over five years, allowing recipients to establish independent research groups and pursue innovative scientific topics. This grant is crucial for building a&nbsp;solid foundation, acquiring necessary equipment, and recruiting talented team members, enabling the pursuit of ambitious projects that can significantly contribute to both the Czech scientific community and global challenges.</p><h5><strong>What collaborations support your research?</strong></h5><p>The collaboration between UCT Prague and the Institute of Organic Chemistry and Biochemistry (IOCB) of the Czech Academy of Sciences primarily provides financial and technical support. The cooperation helps with funding, access to advanced equipment, and operational resources needed for running research projects.</p><h5><strong>What advice would you give young scientists aiming to succeed?</strong></h5><p>I&nbsp;encourage thinking outside the box and combining diverse knowledge you acquire during your career to address complex problems that are exciting and relevant to you.</p><h5><strong>Your laboratory bears the name of Otto Wichterle and was ceremonially opened in the presence of Professor Kamil Wichterle.

If you want to contribute to transformative research in sustainable chemistry and join a&nbsp;dynamic team, this is a&nbsp;great opportunity.</p></div>

JUNIOR STAR Grants at UCT Prague: Two talented women from abroad driving innovation in science

News from LabRulezGCMS Library - Week 06, 2026

<p><strong>Scientists at IOCB Prague are uncovering new details of gene transcription. They have identified a previously unknown molecular mechanism by which the transcription of genetic information from deoxyribonucleic acid (DNA) into ribonucleic acid (RNA) can be initiated. The researchers focused on a specific class of molecules known as alarmones, which are found in cells across a wide range of organisms and whose levels often increase under conditions of cellular stress. The results were published in the prestigious scientific journal </strong><i><strong>Nature Chemical Biology</strong></i><strong>.</strong></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_bc2bfffa6c.jpg" alt="IOCB Prague/Tomáš Belloň: Research from IOCB Prague reveals a previously unknown mechanism of genetic transcription: Dr. Hana Cahová, head of the Chemical Biology of Nucleic Acids research group." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_bc2bfffa6c.jpg 234w," sizes="100vw" width="2000" height="1335"></p><div><p>Molecules of ribonucleic acid can carry a variety of chemical modifications at one end, known as caps. In eukaryotic organisms, including human cells, the best-known cap plays an important role in RNA stability and in regulating its subsequent fate. In recent years, however, it has become clear that alternative, non-canonical RNA caps also exist, although their formation and the mechanisms by which they are attached to RNA remain only partially understood. These include alarmone caps, formed by dinucleoside polyphosphate molecules, that protect cellular RNA at moments when the cell is under threat.</p><p>In their study,<strong> </strong><a target="_blank" rel="noopener noreferrer" href="https://cahova.group.uochb.cz/en"><strong>Dr. Hana Cahová</strong></a> and colleagues examined bacterial RNA polymerase and investigated how this enzyme can initiate transcription using dinucleoside polyphosphates (NpNs) instead of the standard RNA building blocks. For the first time, the scientists described, at the atomic level, how RNA bearing an alarmone cap can be generated directly at the initiation of gene transcription. They also observed that NpNs bind through a different type of base pairing than is typically observed.</p><p>The work was significantly shaped by <strong>Valentina Serianni from Hana Cahová’s team</strong>, who demonstrated the ability of dinucleoside polyphosphates to initiate gene transcription, and by <strong>Jana Škerlová</strong>, who focused on the structural analysis of RNA polymerase. Using cryogenic electron microscopy data, she showed how dinucleoside polyphosphate molecules bind within the active site of RNA polymerase – that is, the core of the enzyme where genetic information is transcribed. Together, their findings help to elucidate the processes that accompany the transcription of genetic information from DNA to RNA.</p><p>Hana Cahová adds: <i>“We’re describing something that truly occurs in cells and that we’re now able to observe directly at the level of individual molecules. This allows us to answer fundamental questions about cellular processes, such as how cells adapt to stress. RNA plays a central role in this, as it carries the cascade of information underlying any cellular response – for example, to threatening conditions caused by nutrient deprivation or temperature shock.”</i></p><p><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg" alt="IOCB Prague/Tomáš Belloň: Research from IOCB Prague reveals a previously unknown mechanism of genetic transcription: Dr. Tomáš Kouba, head of the Cryogenic Electron Microscopy core facility." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_UOCHB_Vyzkum_z_UOCHB_odhaluje_dosud_nepoznany_zpusob_prepisu_geneticke_informace_2_0fe88ff9e9.jpg 234w," sizes="100vw" width="2000" height="1335"></p><div><p>Cryogenic electron microscopy (cryo-EM) was central to the project.

The likely mechanism of this specific capping involves direct incorporation of dinucleoside polyphosphates by RNA polymerase as noncanonical initiating nucleotides. However, how these compounds bind into the active site of RNA polymerase during transcription initiation is unknown. Here, we explored transcription initiation in vitro, using a series of DNA templates in combination with dinucleoside polyphosphates and model RNA polymerase from <i>Thermus</i> <i>thermophilus</i>. We observed that the transcription start site can vary on the basis of the compatibility of the specific template and dinucleoside polyphosphate. Cryo-electron microscopy structures of transcription initiation complexes with dinucleoside polyphosphates revealed that both nucleobase moieties can pair with the DNA template. The first encoded nucleotide pairs in a canonical Watson–Crick manner, whereas the second nucleobase pairs noncanonically in a reverse Watson–Crick manner. Our work provides a structural explanation of how dinucleoside polyphosphates initiate RNA transcription.</p></div></div>
