The cellular environment of a tumor can either support or sabotage recovery. The most comprehensive study to date on the tumor microenvironment in low-grade gliomas, conducted by KiTZ, Jena University Hospital, the DKFZ, and Heidelberg University Hospital, shows what a supportive or obstructive “neighborhood” looks like in childhood brain tumors. The study also provides clues as to how tumor communication might be blocked.

Visual areas of the brain can reveal the colors a person is seeing while watching moving color rings. This was the result of a study by the University of Tübingen. Using MRI scanning they recorded images from the brains of subjects who were observing visual stimuli, and identified signals for red, green and yellow. The pattern of brain activity appeared similar in subjects, meaning that the color they saw could be predicted simply by comparison…

A joint team from the University of Stuttgart in Germany and the University of Melbourne in Australia has developed a new method for the straightforward analysis of tiny nanoplastic particles in environmental samples. One needs only an ordinary optical microscope and a newly developed test strip—the optical sieve. The research results have now been published in “Nature Photonics

Knowing how shrews loose brain volume over winter is the first step to understanding how they reverse this loss and regrow healthy brains in summer.

A molecular mechanism that contributes to the progression of Alzheimer’s disease has been discovered by a research team of Heidelberg University. The team, using an Alzheimer’s mouse model, demonstrated that a neurotoxic protein-protein complex is responsible for nerve cells in the brain dying off and the resulting cognitive decline. This finding opens up new perspectives for the development of effective treatments.

Researchers at the University of Freiburg, together with partners, have uncovered the mechanism of ultrafast transport by calcium pumps in nerve cells. These pumps, complexes of PMCA2 and neuroplastin proteins, operate at more than 5,000 cycles per second and terminate calcium signals within milliseconds – 100 times faster than previously known. They play a crucial role in rapid information processing in the brain.

Svenja Brodt uses MRI brain scans to investigate how impressions become memories. A better understanding of how long-term memories are formed could help Alzheimer's patients cope with their daily lives. Impaired memory formation could be compensated for by targeted repetition.

Every brain tumor is made up of cells in successive stages of activation. Researchers have now analyzed the individual structure of these activation pyramids in malignant brain tumors. In doing so, they discovered a signaling protein that slows down the transition from a dormant to an activated state by epigenetically reprogramming the cells. The hope is that this will permanently freeze cancer cells in a dormant state and thus halt tumor growth.

If the brain no longer responds properly to insulin (insulin resistance), this can lead to overweight, diabetes, and Alzheimer's disease. Researchers at the DZD in Potsdam and Tübingen have discovered small chemical modifications to genetic material (epigenetic changes*) in the blood that indicate how well the brain responds to insulin. These markers could help to detect insulin resistance in the brain – by means of a simple blood test.

The human brain ages less than thought and in layers – at least in the area of the cerebral cortex responsible for the sense of touch. Researchers at DZNE, the University of Magdeburg, and the Hertie Institute for Clinical Brain Research at the University of Tübingen come to this conclusion based on brain scans of young and older adults in addition to studies in mice.

FOXP1 syndrome is a congenital disorder in which the brain development of affected children is severely impaired due to a genetic variant. A research team from the Medical Faculty Heidelberg at Heidelberg University has now demonstrated in mice, that the inhibition of a specific enzyme in the brain can improve abnormal behavior and immune cell dysfunction in the brain. The results have been published in the journal Advanced Science.

Scientists at the Max Planck Institutes for Medical Research in Heidelberg with its new departments based in Heilbronn, and for Neurobiology of Behavior – caesar in Bonn, and at the Institute for Basic Science at Yonsei University in Seoul will pool their expertise in future. The aim of the new Max Planck Center is to visualize cellular processes deep within human tissue and influence them in a targeted manner — without damaging the tissue.

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body - not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This makes the enzyme an interesting candidate for potential future therapeutic approaches.

The ability of protein kinases to transfer a phosphate group to target proteins plays an important role in many cellular processes. Scientists at the Max Planck Institute for Medical Research have now developed a novel molecular tool that can monitor these kinase activities both spatially and temporally. This makes it possible to investigate the link between kinase activities and cellular phenotypes in heterogenous cell populations and in vivo.

Cancer can take decades for cancer-promoting changes in the genome to eventually lead to the formation of a malignant tumor. Researchers at the German Cancer Research Center have now developed a method that allows for the first time to reconstruct the temporal development—the evolution—of cancerous cells from a single tissue sample.

Felix Glang, of the Max Planck Institute for Biological Cybernetics in Tübingen, has been awarded the Otto Hahn Medal in recognition of his achievements in developing new magnetic resonance imaging (MRI) methods. Glang's methods enable clearer and faster brain scans.

For his outstanding achievements in his doctorate at the interface between chemistry and biology, Jonas Wilhelm is awarded an Otto Hahn Medal 2025 by the Max Planck Society. He wrote his thesis in the department Chemical Biology of Kai Johnsson at the Max Planck Institute for Medical Research. In his doctorate, Jonas Wilhelm developed a molecular tool, a biosensor that records and permanently stores biological activities at the cellular level.

Sarcomas in soft tissue usually occur in young people and are difficult to treat. Due to a lack of laboratory models, the causes of their development are poorly understood. A team of researchers has now succeeded in creating mouse models with a functioning immune system that replicate sarcoma types that remain unstudied. The method opens up new avenues for the targeted development of immunotherapies for children and adolescents with sarcomas.

Tübingen achieves remarkable success and has good chance of maintaining its University of Excellence title – Top research in three areas to be sustained from other sources of support.

Many people are infected with the Epstein-Barr virus (EBV), and most are unaware of it. However, EBV can sometimes cause cancer, and this pathogen also appears to play an important role in multiple sclerosis and other autoimmune diseases. Researchers have discovered that EBV increases the ability of infected immune cells to migrate. In this way, the pathogen promotes its spread in the body – a discovery that may have therapeutic implications.

Life-saving smartphone app delivers rapid help during cardiac arrest - 19/05/2025

Do smartphone-based first responder alerting systems increase the chances of survival in the event of cardiac arrest?

Every minute counts when the heart suddenly stops beating or pumps so weakly that the brain is no longer receiving enough oxygen. The HEROES trial, coordinated in Freiburg, is investigating whether the survival rate of patients requiring out-of-hospital resuscitation improves when qualified first responders are alerted via the ‘Region of Lifesavers’ app - enabling them to begin high-quality resuscitation measures as early as possible.

Dr Dr Varun Venkataramani and Dr Moritz Mall have been awarded this year’s Hella Bühler Prize for their outstanding research on the interaction between nerve and tumor cells and on tumor plasticity. The award granted by Heidelberg University goes to young researchers from the Heidelberg research location who have already drawn attention to themselves through the outstanding scientific quality of their cancer research.

Medulloblastomas, childhood brain tumors in children, are thought to develop between the first trimester of pregnancy and the end of the first year of life. Researchers have now published their findings in the journal Nature. They analyzed the genetic changes of each individual cancer cell in tumor samples in order to reconstruct which genetic changes occur first during tumor development and when.

A research team led by PD Dr. Justus Marquet and from the Hertie Institute for Clinical Brain Research has developed two methods that allow muscle activity and training-induced adaptations to be measured completely contactlessly. The studies demonstrate that magnetic fields generated during muscle activity can be captured using highly sensitive quantum sensors - without the need for electrodes or skin contact.

Individuals with a genetic predisposition to Alzheimer’s disease show altered blood levels indicating damaged neuronal contacts as early as 11 years before the expected onset of dementia symptoms. This is evident in the levels of the protein “beta-synuclein”. An international team report these findings in the journal “Alzheimer’s & Dementia”. The biomarker studied here could potentially help to detect neurodegeneration at an early stage.
