Immune cells remember their location

A new AI-based method reconstructs spatial information about where immune cells were originally located in an organ, even after these cells have been removed from the tissue and analyzed individually. To accomplish this, Researchers at the University Hospital Bonn (UKB) and the University of Bonn use the transcriptome, i.e., the entirety of all messenger RNA transcripts produced by genes within a cell at a given time. The work has now been published in the journal Advanced Science and introduces the new MERLIN algorithm.

Mitochondria influence lipid storage in cells

The powerhouse of the cells – known as mitochondria – appear to be able to influence the number of lipid droplets in the cell. A mechanism that is actually intended for a completely different purpose plays a central role in this. This is shown by a recent study by the University of Bonn and University Hospital Bonn and the University of Freiburg. The results have now been published in the journal Nature Cell Biology.

New approaches to environmental peace in Colombia

Investigating and combining new and existing technologies with Indigenous knowledge systems – that is the aim of ‘iakumama 2050.’ The new research project by the Center for Development Research at the University of Bonn (ZEF) pursues the goal of developing scenarios for how humans and nature can live together in regions affected by armed conflicts and raw material extraction. The Volkswagen Foundation is funding the project, which begins in July 2026 and will then be funded for one and a half years.

What makes sea urchin and salmon sperm swim

A study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn has shown that pH value is crucial for sperm motility in sea urchins and salmon. An increase in pH activates the enzyme adenylyl cyclase (sAC), which produces the messenger substance cAMP, thereby regulating sperm motility. This mechanism may be widespread among many marine invertebrates and fish. The researchers' findings have now been published in the renowned journal Proceedings of the National Academy of Sciences.

New findings on infection with the Epstein-Barr virus

The Epstein-Barr virus (EBV) can cause certain types of cancer or autoimmune diseases, but how the body controls this common viral infection is largely unknown. Researchers at the University Hospital Bonn (UKB) and the University of Bonn have now identified genetic and non-genetic factors that help the body fight EBV. To do this, they evaluated genome sequencing data, which is actually intended for characterizing the human genome, in a new way. Using the new technique, they were able to estimate the amount of EBV in the blood and find correlations in large health data sets – for example, an increased viral load in people with HIV infections, but also in smokers. There were also indications of new genes that play key roles in EBV immunity. Their findings have now been published in the renowned journal Nature.

Stellar remnants solve the mystery of missing mass in galaxy clusters

Under the leadership of the University of Bonn, a research team led by Prof. Dr. Pavel Kroupa from the Helmholtz Institute for Radiation and Nuclear Physics has discovered that galaxy clusters are about twice as heavy as previously assumed. The additional mass comes mainly from neutron stars and stellar black holes and also explains the observed quantities of heavy elements.

Certification Boosts Sustainability in the Lab

Lab-based research is essential to advances in technology, but it is also one of the most resource-hungry areas of science. The University of Bonn and University Hospital Bonn introduced the internationally recognized Laboratory Efficiency Assessment Framework (LEAF) program last year in a bid to shrink the environmental footprint of its research laboratories in a systematic way. Five pilot laboratories have now passed their assessment and been awarded Bronze certificates.
