EU supports team led by molecular biologist Brigitte Pertschy with around ten million euro

The European Research Council (ERC) is funding the snoOPERA project with around ten million euros to research the structure of cellular protein factories. The four researchers involved want to clarify how tiny RNA-protein complexes control the formation of ribosomes—a key to understanding diseases such as cancer and Alzheimer's.

Proteins are essential for the survival of all cells. They are continuously produced in the body’s protein factories — the ribosomes. How ribosomes are assembled is at the heart of a cutting-edge research project funded by the EU and coordinated by the University of Graz. Partners in Germany, France, and the USA are also involved. The European Research Council (ERC) is supporting the project “snoOPERA” with a total of around ten million euros over six years.

Rector Peter Riedler expressed his delight about of the most demanding and prestigious research grants in Europe: “Awards such as the ERC Synergy Grant demonstrate that our researchers are working at the highest international level and making important contributions to understanding fundamental biological processes.”

A Look into the Molecular Orchestra

Errors in ribosome formation can have serious consequences, explains Brigitte Pertschy from the Institute of Molecular Biosciences at the University of Graz: “If something goes wrong during assembly, protein production is disrupted. And that, in turn, is suspected to be involved in diseases such as cancer or neurodegenerative disorders.” However, the project is still focused on basic research: “We want to understand how these cellular machines are properly formed in the first place.” The researchers are focusing on specific small RNA–protein complexes called snoRNPs.

“These molecules are like invisible conductors in a gigantic orchestra,” Pertschy says. “We have discovered that a whole group of these small particles has far more functions than previously thought — they actively assist in ribosome assembly.” Using state-of-the-art techniques such as cryo-electron microscopy as well as genetic, biochemical, and biophysical analyses, the team aims to trace how these processes occur inside cells. Beyond the scientific objectives, the project also emphasizes the exchange of technologies and methods between participating laboratories.

“Our doctoral students and postdocs will travel between Graz, Munich, Toulouse, and Baltimore — this is international collaboration in action,” Pertschy adds.

66 Research Teams Awarded Synergy Grants

The snoOPERA project is among the 66 proposals selected this year by the ERC from more than 700 submissions. In total, 239 researchers will receive funding amounting to 684 million euros. The Synergy Grants enable scientists to join forces and tackle particularly complex research questions.

Fair distribution: Researchers determine just greenhouse gas budgets for all EU regions

Ten years ago, on 12 December 2015, the Paris Climate Agreement was signed at the UN Climate Conference. In order to limit global warming to well below two degrees, only a certain amount of CO2 may be emitted worldwide. While the focus was originally on national emission targets, more than 200 subnational regions and almost 300 cities have now adopted their own targets. But how many emissions are they fairly entitled to? Researchers at the University of Graz have now developed transparent criteria for fair distribution at the subnational level for the first time and determined corresponding greenhouse gas budgets for all European regions. The paper was published today in the scientific journal Nature Communications.

Chemical Christmas show at the University of Graz: An explosive evening at the Schauspielh

At the beginning of December, the University of Graz transformed the theater into a laboratory: as part of “Chemical Life,” teacher training students staged a chemical Christmas show for Styrian school classes—complete with ethanol rockets, nitrogen snow, and glowing effects. An evening designed to inspire interest in studying chemistry.

Lectures at the University of Klagenfurt in the morning, seminars at the University of Graz in the afternoon: Austria's longest tunnel and a journey time of around 45 minutes make it easy. The Koralm railway increases the speed of networking between the two university locations. The collaboration builds on existing cooperation - for example in the areas of teacher training, Slavic studies and as employers, the universities are well coordinated.
