Computer tool opens up new ways to address antibiotic resistance - 02/07/2025

PhARIS identifies effective phages against multi-resistant bacteria

Bacteriophages - viruses that specifically attack and destroy bacteria - are emerging as promising alternatives to antibiotics in the fight against drug-resistant infections. To speed this effort, researchers have created PhARIS, a computational tool that mines genomic data to pinpoint phages that are effective against S. aureus. By rapidly matching phage and pathogen, PhARIS can accelerate the development of targeted phage therapies.

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.

Computer scientist Annika Reinke from the German Cancer Research Center (DKFZ) has been awarded the Hector Foundation Prize 2025, endowed with €10,000, for her outstanding work in the field of AI-supported medical image analysis. She received the award for the project Metrics Reloaded, which can significantly improve the quality and reliability of AI-supported image analysis.

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.

Cell-based solution in place of animal testing - 05/06/2025

Innovative cell-based test to detect pyrogens in drugs

Drug safety testing for microbial contaminants and fever-inducing substances (pyrogens) still frequently uses animal experiments. InnoZell, a start-up that will soon be spun off from the University of Konstanz, has developed a compelling alternative: an animal-free, human cell-based assay that is faster, more sensitive and more reliable than traditional methods – and can be customised to meet user-specific needs.

The reservoir of blood stem cells shrinks with age. It becomes increasingly dominated by stem cells that produce immune cells associated with chronic inflammation. Almost all of the 60-year-olds studied show this change. The new discovery could help explain the chronic inflammation that occurs with age and makes us more susceptible to disease. It could also help identify early warning signs of unhealthy aging processes.

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.

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.

The Max Planck Society and the Dieter Schwarz Foundation (DSS) have embarked on a groundbreaking initiative. On March 13, 2025, they signed an agreement through which the foundation will support an innovative approach by the Max Planck Institute for Medical Research in Heidelberg to translate basic research findings into practical applications. As part of this endeavour, two new departments of the institute will be established in Heilbronn.

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions have hardly been studied to date. Researchers from the German Cancer Research Center, the Mannheim Medical Faculty and Columbia University have now published that hepatic stellate cells control liver metabolism as well as liver regeneration and size. The results of the study could contribute to new therapeutic approaches for liver diseases.

Donating blood saves lives – but what long-term effects does this practice have on our bodies? Researchers from the German Cancer Research Center (DKFZ), the HI-STEM stem cell institute* and the German Red Cross Blood Donor Service, among others, have now discovered that frequent blood donations cause genetic adaptations in blood stem cells that promote the regeneration of blood cells.
