Fractures in focus: predicting rather than waiting

Bone fractures are generally healed by the body without any issues. However, there are hundreds of thousands of cases each year in which a fracture either fails to heal or only does so slowly. To reduce the number of cases where this happens, a start-up called OSORA medical has developed methods to predict the healing process and, if necessary, make preventative adjustments.

Her ground-breaking research studies on the regulation of gene activity have earned Dr Angelika Feldmann the Hella Bühler Prize for 2026, which is endowed with 100,000 euros.

Brain metastases are among the most serious complications of breast cancer. Researchers at Heidelberg University, DKFZ, and UKHD have concluded an investigation of the immune cells in the brain tissue surrounding these breast cancer brain metastases. Their findings: spatial distribution patterns of immune cells are associated with prolonged patient survival. These findings could help to guide use of immunotherapies for breast cancer patients.

The cities of Heidelberg and Mainz want to work closely together in the future: Their aim is to further develop the Neckar-Rhine-Main region as an international innovation and biotech region. To this end, Heidelberg Mayor Würzner and Mainz Mayor Haase signed a MoU at Heidelberg City Hall on Friday, April 24, 2026. Those responsible for the central innovation and development structures of both cities also took part in the signing.

Prof. Dr. Halbritter has served as the new Medical Director of the Department of Nephrology at the Medical Center – University of Freiburg since April 2026. With his expertise, he is enhancing care for patients with kidney disease: The goal is to prevent kidney failure through early diagnosis and the implementation of strategies to slow disease progression. For cases where kidney failure has already occurred, the focus is on organ replacement.

Within biological cells, molecules are constantly in motion. Investigating these motions, however, is still difficult, due to the fact that these processes occur on very small length and time scales. To overcome these challenges, researchers from HITS and MPI-P have developed a simulation method that works rapidly and can predict chemical processes in cells with high precision. Their findings have been published in Nature Communications.

Not only actual chronological age, but also individual aging at the molecular level is a key factor in the development of cancer. This was discovered by scientists at the DKFZ and the Saarland Cancer Registry. If the so-called “epigenetic clocks” indicate accelerated biological aging, the likelihood of a cancer diagnosis increases. This finding could help identify at-risk groups and make early detection screenings more targeted

Genome duplication probably gave biodiversity a decisive evolutionary boost. A Chinese-German research team led by Axel Meyer from the University of Konstanz has now investigated the early phases of the process known as re-diploidization. The results show that the fusion of chromosome sets is asynchronous.

A novel biomimetic tissue substitute combines precisely tunable mechanical properties with biological functionality and is now ready for applications in medical technology. The material was developed in the »PolyKARD« project by Fraunhofer IAP and the NMI Natural and Medical Sciences Institute. From 20.-24.04, 2026, the material will be presented together with further developments at the Hannover Messe, Fraunhofer joint booth.

Estrogen does more than regulate reproduction — it helps brain cells handle stress. When levels decline after menopause, this ability is reduced, and these hormonal changes are believed to contribute to the increased risk of Alzheimer’s disease in women. MPI-IE researcher María José Pérez Jiménez has received the Klaus Tschira Boost Fund to investigate why — and whether these cellular responses can be restored.​

How can you charge electric cars without plugging them into the power grid for hours on end? How can industrial robots be “refueled” during operation? And how does wireless energy transfer improve medical technology? These questions have occupied Prof. Nejila Parspour, Director of the Institute of Electrical Energy Conversion (IEW) at the University of Stuttgart, for more than twenty years.

Brain-computer interfaces can read neural signals and influence brain activity. We spoke with Pascal Fries about how this technology can benefit people with neurological and psychiatric conditions, future developments, and his views on ethical boundaries.

Chronic infections cause long-term changes in key immune cells. T helper cells suppress their immune function to ensure their survival. New targets for vaccines and cancer immunotherapies.

Europe’s dependence on fossil fuels is not only making the continent economically and politically vulnerable, it also has consequences for the population’s health. Growing air pollution, heat damage and the climate-related spread of infectious diseases are looming, warns the 2026 Europe Report of the Lancet Countdown on Health and Climate Change, which its co-directors are about to present to the public.

A recent study published in the European Respiratory Journal provides important new insights into the early identification and monitoring of chronic obstructive pulmonary disease (COPD). The focus is on airway wall thickness as an imaging marker for structural remodeling processes in the lungs.

A team of researchers from the Department of Integrative Evolutionary Biology at the Max Planck Institute for Biology Tübingen has discovered that vitamin B12 plays a key role in transmitting behavioural memories across generations. The study shows for the first time how a nutrient from the diet can, without altering the genome, influence behaviour over multiple generations.

Desmoplastic small- and round-cell tumor is rare, aggressive, and difficult to treat. Researchers at the National Center for Tumor Diseases (NCT) Heidelberg and the German Cancer Research Center (DKFZ) have comprehensively analyzed 30 tumors and identified potential personalized treatment options for nearly all patients. In some patients, new targeted approaches were able to halt the disease for a surprisingly long time.

Can Aztekin and his team have discovered how oxygen-sensing explains why amphibians regenerate limbs and mammals do not.

Switching off tumours with light: how photons can be used to target prostate cancer

Prostate cancer is the most common cancer among men in Germany. Relapses and the harsh side effects of traditional treatments remain a major challenge, even with advanced surgical techniques. At the University of Freiburg, Dr. Wolf is pioneering the development of photoimmunotherapy. Photoimmunotherapy combines light, antibodies and a specialised dye to precisely target tumour cells - simultaneously 'waking up' the immune system.

For over a decade, a class of drugs called BET inhibitors has been tested in cancer trials with high expectations. The biology looked promising. Many cancers depend on oncogenes that (BET) proteins help activate, so blocking BET proteins should slow tumor growth. In the lab, it often did. In patients, results were mostly disappointing: limited responses, significant side effects, and no clear way to predict which tumors would respond at all.

How does sugar affect relaxation exercises? A new study carried out by researchers from the University of Konstanz provides revealing insights into the connection between blood glucose and the autonomic nervous system: The intake of sugar counteracts relaxation.

Computer simulations and Artificial Intelligence are the main pillars of the “SIMPLAIX” collaboration, initiated by the Heidelberg Institute for Theoretical Studies (HITS). Together with colleagues from Heidelberg University and Karlsruhe Institute of Technology, HITS researchers are addressing challenges in the simulation of biomolecules and molecular materials by pooling their expertise in multiscale computer simulation and machine learning.

The Volkswagen Foundation is supporting the Ulm scientist Professor Walter Karlen with more than 940,000 euros from the funding initiative "Momentum - funding for first-time researchers". The engineer has headed the Institute of Biomedical Engineering at Ulm University since 2021. Karlen conducts research in the field of mobile health on so-called Medicine Wearables, i.e. portable technology for recording health data.
