Innovative tubular prosthesis enables reversible treatment for type 2 diabetes

Severe obesity is considered a major cause of type 2 diabetes. Building on gastric bypass surgery, the Mannheim-based company Trans-Duodenal Concepts has developed an endoscopically implantable tubular prosthesis that lines the duodenum. This both reduces food intake and can restore normal blood sugar metabolism.

It has only recently become known that two parallel systems of blood formation exist in the body. Researchers at the DKFZ have developed a method to examine both systems separately in mice for the first time. Their surprising finding: the majority of immune cells do not originate from classic blood stem cells in the bone marrow, but from precursor cells that are independent of blood stem cells and are already present in the embryo.

Physician and cancer researcher Mirco Julian Friedrich from the German Cancer Research Center (DKFZ), the stem cell research institute HI-STEM*, and Heidelberg University Hospital (UKHD) has received two awards for two independent research projects: his novel approach to preventing liver metastases and his research on T cells, which he modifies to better protect them from attacks by natural killer cells.

With victims numbering in the millions, malaria is an infectious disease caused by the bite of a mosquito carrying the malaria parasite. After penetrating the skin, the pathogen moves with helical trajectories. It almost always turns toward the right, as a team of physicists and malaria researchers from Heidelberg University recently discovered.

Researchers from the German Cancer Research Center and the University of Freiburg show how certain painkillers influence the iron metabolism of liver cancer cells and can thus contribute to iron deficiency and anemia in cancer patients.

Researchers have developed a new method that greatly improves the accuracy of brain-state classification with functional near-infrared spectroscopy (fNIRS). The brain-imaging technique fNIRS allows researchers to measure neural activity: Active brain cells need more oxygen, so variations in blood flow and oxygen saturation indicate which brain regions are at work. fNIRS detects these changes safely and without invasive procedures.

Ependymomas, brain tumors that occur particularly in young children, are especially difficult to treat and more than half of the children affected have an increased risk of relapse. As part of an international consortium, the KiTZ, the DKFZ, the MFHD and UKHD have received a grant of 1.5 million pounds sterling (GBP) from the British organization The Brain Tumor Charity to develop a new type of immunotherapy for ependymoma.

The Federal Ministry of Research, Technology and Space (BMFTR) is supporting the “Sleep-Neuro-Path” research network with around 1.6 million euros.

A method developed at the Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB enables bacterial, viral, fungal, or parasitic pathogens in sepsis patients to be identified much faster than before and with the highest precision. The approach is based on high-throughput sequencing of cell-free DNA circulating in the blood and was honored with the EARTO Innovation Award in the "Impact Delivered" category on October 14,…

Tumors are not a comfortable place to live: oxygen deficiency, nutrient scarcity, and the accumulation of sometimes harmful metabolic products constantly stress cancer cells. A research team from the DKFZ and the IMP in Vienna has now discovered that the acidic pH value in tumor tissue is a decisive factor in how pancreatic cancer cells adapt their energy metabolism in order to survive under these adverse conditions.

Human immunodeficiency viruses (HIV) are insidious. They can evade the immune defence and antiviral drugs by becoming "latent". In this state, they are largely invisible and unassailable. As long as these dormant viruses persist, there is no cure for HIV/AIDS. However, researchers at Ulm University Hospital have discovered a new way to reactivate latent HI viruses.

Powerful AI systems using synthetic training data

AI systems for image analysis are only as good as the data on which they are trained. The Göppingen-based start-up MIRA Vision has developed a novel method for generating synthetic, photorealistic images, enabling the efficient creation of large, high-quality training datasets. An intuitive platform also allows researchers to evaluate microscopy images with ease.

Why is blood cancer particularly aggressive in some patients? Researchers at Ulm University Hospital have characterised a mutation in the so-called NOTCH1 gene that significantly influences the prognosis of chronic lymphocytic leukaemia (CLL). Remarkably, this mutation is located in the non-coding region of the gene – an area of DNA long considered less relevant for disease mechanisms.

Researchers have discovered part of the answer to why some people with obesity or diabetes develop fatty liver disease while others remain healthier. They showed that fat cells have their own protective mechanism that prevents them from dying prematurely under stress. If this mechanism fails, the fat cells disintegrate. This can lead to tissue damage, inflammation and serious metabolic disorders.

Scientists from the European Molecular Biology Laboratory (EMBL) and the German Cancer Research Center (DKFZ) have developed an AI model that assesses the long-term individual risk for more than 1,000 diseases. The model, which was trained and tested using anonymized medical data from the UK and Denmark, can predict health events over a period of more than a decade.

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.

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.

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

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.

Tumors of the pancreas seldom cause symptoms in their early stages. This means that in many cases, they are not diagnosed until late, when the chances of successful treatment are poor. A new non-invasive diagnostic method designed by Fraunhofer researchers is set to make it possible to detect this aggressive form of cancer early on with high accuracy, significantly improving the prognosis for treatment.

How can the transformation to increase sustainability in hospitals succeed? Participants in the SustainMed project presented their answers at the closing event on 27 June 2025 in Stuttgart. The Ministry of the Environment, Climate Protection and the Energy Sector Baden-Württemberg provided approximately 500,000 euros in funding to develop solutions for goals such as reducing volumes of waste in hospitals.

Stem cell-like leukemia cells are responsible for relapses in children and adolescents with a certain type of blood cancer, T-ALL. Researchers at the Hopp Children's Cancer Center Heidelberg (KiTZ), the Molecular Medicine Partnership Unit and the German Cancer Research Center were able to show this in a study. The results could help to overcome resistance in this form of blood cancer and prevent relapses.

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.

Diabetics have a higher risk of colorectal cancer and often a poorer prognosis after developing the disease. The biological mechanisms behind this association were largely unknown. A research team at the German Cancer Research Center (DKFZ) has now discovered that tumors with a low number of immune cells appear to be particularly susceptible to the harmful effects of diabetes.

Many people with cancer experience dramatic loss of muscle and fat tissue. In many cases, even the heart muscle is affected. This wasting syndrome, affects around half of all cancer patients. Researchers from Helmholtz Munich, in collaboration with Heidelberg University Hospital, the Technical University of Munich, and the German Center for Diabetes Research, have now identified a previously overlooked driver of cachexia: the liver.

Sepsis is one of the most dangerous medical emergencies. The condition is the result of a misdirected immune response to an infection, which can quickly lead to organ failure and death. Every hour counts – but early detection is difficult. A new study from Heidelberg now presents an innovative approach: artificial intelligence (AI) and hyperspectral imaging of the skin enable immediate and non-invasive sepsis diagnosis directly at the bedside.

Researchers from the Max Planck Institute of Immunobiology and Epigenetics in Freiburg and ETH Zürich have created the first integrated map detailing the metabolic and molecular changes in human blood stem cells as they age, specialize, or turn cancerous. Their innovative research, made possible by highly sensitive low-input techniques, identifies the nutrient choline, as a key player in preserving youthful stem cell traits.

Researchers at the German Centre for Cardiovascular Research (DZHK) have identified a key molecule involved in a form of heart failure that has so far been difficult to treat.

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.

Scientists have been working on the artificial production of blood for several decades. Making a new discovery, researchers from the Institute for Cellular Biology and Immunology Thurgau at the University of Konstanz, in collaboration with Queen Mary University of London, have come an important step closer to this goal.

The skeletal muscles of men and women process glucose and fats in different ways. A study provides the first comprehensive molecular analysis of these differences. The results possibly give an explanation why metabolic diseases such as diabetes manifest differently in women and men – and why they respond differently to physical activity.

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.

Colorectal cancer screening programs are currently underutilized in Germany. This also applies to testing for blood in the stool. The immunological stool tests can detect tiny amounts of blood in the stool. Scientists at the German Cancer Research Center (DKFZ) have investigated whether smartphone-based testing could be a meaningful alternative or supplement to traditional laboratory tests.

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.

3D bioprinting is a great hope in the field of regenerative medicine to produce miniaturized tissues and organ precursors with biological functionality. Today, however, scientists are still working on the challenge of producing a printable and at the same time compatible starting material.

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.
