Breath test replaces invasive diagnostics - 30/07/2025

Novel smartphone sensor offers innovative breath test to detect Helicobacter infection

The stomach bacterium Helicobacter pylori is widespread and, if left undetected, can impact our well-being and also lead to serious health conditions. While effective treatments exist, a reliable diagnosis is essential. To address this, researchers have developed an affordable breath test that uses a mini-sensor to detect the presence of the bacterium. They are currently working on a smartphone-compatible version for self-testing.

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.

Structured management of health data - 14/08/2025

Data governance in the healthcare sector

The healthcare sector generates an increasing volume of data, yet much of it remains underutilised or inadequately secured. Implementing robust data governance - a structured framework for collecting, managing and protecting data - could unlock this untapped potential and lay the foundation for improved patient care.

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.

Medical technology plays a key role in health and makes a contribution to improving quality of life. The spectrum of medical technology ranges from disposable products, IT-based applications to innovative technologies. In Baden-Württemberg, 836 companies are active in research, development and/or production in this field, making medical technology one of the most important economic sectors in the state.

Baden-Württemberg is currently home to 193 biotechnology companies, most of which specialise in so-called ‘red biotechnology’ - i.e. applications in the medical and pharmaceutical sectors. The biotech sector includes not only traditional biotechnology companies, but also companies from the fields of bioinformatics, diagnostics, analytics and biotechnological production.

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.

Until now, the early phase of drug discovery for the development of new therapeutics has been cost- and time-intensive. Researchers at KIT have developed a platform on which extremely miniaturized nanodroplets with a volume of 200 nanoliters per droplet and containing 300 cells per test can be arranged. This platform enables the researchers to synthesize and test thousands of therapeutic agents on the same chip, saving time and resources.

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.

Enhancing human perception of the imperceptible - 28/08/2025

AI-driven imaging expands possibilities in surgery

Doctors frequently experience a restricted view of the surgical field, particularly during endoscopic procedures. A novel technique developed by Prof. Dr. Lena Maier-Hein's team at the DKFZ in Heidelberg integrates spectral imaging with AI-driven data analysis. This innovation facilitates accurate tissue differentiation and delivers real-time insights into organ function.

A team of scientists from the German Cancer Research Center (DKFZ) and the Netherlands Cancer Institute has discovered a previously unknown vulnerability in cancer cells: When cell division is blocked with chemotherapeutic agents such as Taxol, cancer cells produce small immunogenic peptides that could open up new avenues for immune-based cancer therapies.

The maturation process of oocytes remains paused for several years. Researchers from Konstanz and Göttingen have now found out which protein ensures this state is maintained over such a long period.

Researchers from the German Cancer Research Center (DKFZ) have collaborated with the SILVACX project group at Heidelberg University to develop a therapeutic vaccination concept that can mobilize the immune system to target cancer cells. The team showed that virus peptides coupled to silica nanoparticles can elicit effective T-cell responses against HPV-related tumors.

When embryos grow, cells and tissue are constantly bumping into each other. This creates mechanical tensions that could endanger their development. A team from University of Hohenheim and the Japanese RIKEN Center have discovered that fly embryos have strategies to deal with this pressure. The different species have developed two different solutions. This ability to control mechanical tension could be a key to why so many body plans have evolved.

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

The rapid increase in antibiotic-resistant bacteria is one of the most pressing challenges facing global health. A new transatlantic Fraunhofer research project aims to counter these threats with an innovative diagnostic approach: a microfluidic rapid test system using carbon nanotubes (SWCNT) will make bacterial resistance visible in just a few minutes, significantly faster than conventional methods.

Chordomas are rare bone tumors for which there are no effective drugs. A research team from the DKFZ and the NCT Heidelberg has now developed a promising approach: Tailor-made mini-proteins specifically block the driver of tumor development. In the result, slowing the growth of chordoma cells in the laboratory and in a mouse model, while also revealing further molecular vulnerabilities of the tumor that could be addressed with approved drugs.

Fluorescence and smartphones instead of laboratories - 11/09/2025

Mobile blood-analysis system for at home medication monitoring

For many medications, regular monitoring of drug concentrations in the blood is necessary to ensure efficacy and safety. Until now, this process has been time-consuming and required laboratory personnel and resources. The Heidelberg based start up QuantiLight has developed a mobile device with innovative sensor technology that enables quick, easy measurements at home or in a doctor's surgery.
