Using nanostructures to fight bacteria - 09/10/2025

Inspired by insect wings: antibacterial surfaces for implants

What do dragonfly wings and dental implants have in common? Nothing yet but that could soon change. The Karlsruhe-based start-up nanoshape has developed a process for coating medical implants with nanostructures similar to those found on insect wings. The coating makes surfaces bacteria-repellent and is aimed at reducing the risk of post-surgical inflammation. The first product could be on the market as early as next year.

An imaging technique developed by Freiburg researchers provides insights into cardiac arrhythmias that can cause sudden cardiac death in animal models. The changes discovered could explain why even seemingly healthy people are sometimes affected.

Researchers from the Cluster of Excellence CIBSS have demonstrated that an actin scaffold stabilizes the cell nucleus upon mechanical stress. This protective mechanism helps cancer cells to avoid dying during their migration in the body. In the long term, targeted interventions in this mechanism could help to prevent metastases.

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.

Since their discovery in 2004, the grid cells in the brain, which are important for our orientation, have been regarded as a kind of “GPS in the head.” However, scientists at the DKFZ and Heidelberg University Hospital have now shown that grid cells work much more flexibly than previously assumed. In experiments with mice, the researchers found that the cells adapt their activity to different reference points depending on the situation.

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.

On the basis of the cooperative relations that have developed over time, Heidelberg University and Harvard University are going to deepen and expand their cooperation. They have signed a Memorandum of Understanding to that effect. As an institutional internationalization project, the state of Baden-Württemberg is providing ten million euros to support this initiative, which is part of the state’s “Global Partnership in Science” activities.

About five percent of lung adenocarcinomas, one of the most common forms of lung cancer, are driven by a faulty fusion of two genes, EML4 and ALK. This fusion results in different variants, and until now, clinicians have treated all patients with these fusions the same way. However, new research led by scientists from the German Cancer Research Center (DKFZ) and Stanford University shows that not all fusion variants behave alike.

With the FeMEA project – Ferroelectric Microelectrodes for Biomedical Applications – Hahn-Schickard is setting a pioneering course in bioelectronics research. The aim of the project is to develop novel microelectrode arrays in which ferroelectric materials are used as functional interfaces in CMOS chips for the first time.

The groninger Group has acquired Reinraumtechnik Ulm GmbH (RTU). With this strategic move, the family-owned company headquartered in Crailsheim not only expands its technological portfolio but also strengthens its expertise in a field that is crucial to the pharmaceutical industry: cleanroom and isolator technology.

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 2020 Nobel Prize in Chemistry was awarded for the development of CRISPR/Cas9, a method also known as “gene scissors”, which enables researchers to better understand how human cells function and stay healthy. Researchers at the University of Stuttgart have further developed CRISPR for this purpose. They present their CRISPRgenee method in Cell Reports Methods.

Researchers at Heidelberg Uni Hospital have decoded a previously unknown mechanism by which HIV-1 selects its integration targets in the human genome. A research team identified RNA:DNA hybrids as molecular signposts for the virus. These findings reveal a vulnerability in the life cycle of HIV and provide therapeutic approaches for specifically controlling HIV reservoirs in the body. This has been one of the obstacles to curative HIV therapies.

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.

Soft robots, robot systems made of soft materials, open up new perspectives for medical technology and industry. Jun.-Prof. Dr. Aniket Pal from the University of Stuttgart is conducting research into viscoelastic materials that have the potential to embed intelligent functions in soft robots. He is receiving 1.5 million euros in funding for this research as part of the Emmy Noether Program. The funding period began on September 1, 2025.

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…

In the human body, stem cells process genetic information in an exceptionally reliable and very fast manner. To do this, they access certain sections of the DNA in the cell nucleus. Researchers at KIT have investigated how the DNA-based information processing system works. Their results show that this process is comparable to processes in modern computers and could therefore serve as a model for new types of DNA-based computer chips.

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

Alumnus Bastian Linder discusses the origin of this start-up and how a tRNA mechanism is helping scientists understand the importance and use of various RNA modifications as they pertain to disease.
