A team of engineers and biotechnologists at the University of Freiburg has for the first time shown in mammals that the concentration of antibiotics in the body can be determined using breath samples. The breath measurements also corresponded to the antibiotic concentrations in the blood. The team’s biosensor – a multiplex chip – will in future enable personalized dosing of medicines against infectious diseases on-site.

Christiane Opitz, scientist at the German Cancer Research Center, is being awarded this year's Ita Askonas Prize of the European Federation of Immunological Societies. Opitz has discovered how tumor cells use certain metabolites to protect themselves against the immune system. Her research findings may provide important clues for the development of new therapeutic concepts.

On the one hand, blood vessels supply tumors with nutrients and, on the other, enable cancer cells to spread throughout the body. The settlement of circulating tumor cells in a distant organ is promoted by factors whose production is induced by the primary tumor itself. Scientists have now identified a new growth factor produced by blood vessels that enables tumor cells to metastatically colonize organs.

Scientists use super-resolution microscopy to study previously undiscovered cellular worlds, revealing nanometer-scale details inside cells. This method revolutionized light microscopy and earned its inventors the 2014 Nobel Prize in Chemistry. In an international collaboration, AI researchers from Tübingen have now developed an algorithm that significantly accelerates this technology.

Health Data Scenarios - many possibilities for the future?

The digitization of healthcare is progressing slowly but steadily. In addition to simple telemedical applications, data such as electronic patient records are forming the basis of digitization. The ‘Health Data Scenarios’ project aims to model the future of healthcare data by using scenarios. Lucas Scherdel, Healthcare Innovation Director at DayOne, and Dr. Alexander Fink, founder and CEO of ScMI AG, explain how this will work.

EMBL scientists pave the way for reducing the harmful side effects antibiotics have on gut bacteria. Antibiotics help us to treat bacterial infections and save millions of lives each year. But they can also harm the helpful microbes residing in our gut, weakening one of our body’s first lines of defence against pathogens and compromising the multiple beneficial effects our microbiota has for our health.

New multispectral imaging technology improves endoscopic tumour detection capabilities

The quality of minimally invasive surgery depends to a large extent on the imaging properties of the endoscopes used. The Mannheim-based company Thericon GmbH has developed a multispectral imaging technology that overlays views from multiple light channels in real time to create a detailed image on which tumours can be better identified.

An international study with about 3000 patients confirms the validity of a new classification system for meningiomas. It combines tissue characteristics (histology) with molecular analyses and thus improves therapy planning.

A pioneering technique developed by the Prevedel Group at EMBL allows neuroscientists to observe live neurons deep inside the brain – or any other cell hidden within an opaque tissue. The technique is based on two state-of-the-art microscopy methods, three-photon microscopy and adaptive optics. The paper reporting on this advancement was published on 30th September 2021 in Nature Methods.

International research collaboration explores the properties of different neuron types in the brain motor cortex of mice, monkeys and humans using novel experimental and data analysis techniques.

CureVac N.V., a global biopharmaceutical company developing a new class of transformative medicines based on messenger ribonucleic acid (“mRNA”), today announced the strategic decision to focus its COVID-19 vaccine development towards the development of second-generation mRNA vaccine candidates in collaboration with GSK and to withdraw its first-generation COVID-19 vaccine candidate, CVnCoV, from the current approval process.

The mechanisms by which the body measures temperature and regulates its own body heat are vital, but still poorly understood. The discovery of the first heat sensor on nerve cells in the skin, for which the U.S. molecular biologist David Julius received this year's Nobel Prize for Medicine, was therefore pioneering.

Microorganisms can increase their host’s ability to adapt to the environment and reproduce – evolutionary biologists are now studying the underlying molecular mechanisms. A research team headed by Dr. Fabian Staubach and Yun Wang from the Institute of Biology I at the University of Freiburg has now studied the relationship of Gluconobacter bacteria and fruit flies. They have found that specific Gluconobacter variants supply the flies with vitamin…

Acetate supports immune cells to fight against sepsis

Blood poisoning is the most dangerous complication of bacterial infections and often leads to death. Researchers at the Interfaculty Institute of Microbiology and Infection Medicine at the University of Tübingen have now identified acetate as a potent agent for stimulating innate immune system cells, supporting their ability to destroy bacteria.

Prof. Dr. Harald Gießen from the Institute of Physics (4) as well as Prof. Dr. Alois Herkommer and Dr. Simon Thiele from the Institute of Applied Optics at the University of Stuttgart received the Gips Schüle Research Award 2021 on October 19, 2021. The researchers were awarded the prize, which is valued at EUR 50,000.

Rolandic epilepsy is a common form of epilepsy in children which occurs primarily during sleep. Short sounds played during sleep can partially suppress the neuronal discharges characteristic of epilepsy. That’s according to a research team from the University of Tübingen and Tübingen University Hospitals. The team is headed by Dr. Hong-Viet Ngo and Professor Jan Born from the Institute of Medical Psychology and Behavioral Neurobiology.

Doctors and scientists from the German Cancer Research Center (DKFZ) and from Heidelberg University's Medical Faculty Mannheim have successfully tested a neoantigen-specific transgenic immune cell therapy for malignant brain tumors for the first time using an experimental model in mice.

Nanoparticles are omnipresent in our environment: Viruses in ambient air, proteins in the body, as building blocks of new materials for electronics, or in surface coatings. Visualizing these smallest particles is a problem: They are so small that they can hardly be seen under an optical microscope.

Plastic products can be found everywhere in daily life, soft plastic in particular often being used for packaging or children's toys. These often contain so-called plasticizers which ensure that the material remains flexible. Because plasticizers are not bonded permanently to the plastic, they can escape from the material, meaning they can be absorbed by humans.
