Quantum sensors for exoskeletons: can quantum physics beat paralysis?

Could people suddenly be able to move again decades after being paralysed? State-of-the-art quantum sensors integrated in exoskeletons could make this possible. Technology being developed as part of the BMBF-funded NeuroQ beacon project by researchers from organisations including the Fraunhofer IAF, the Charité in Berlin and the University of Stuttgart might achieve even more: besides facilitating movement, it could also help cure paralysis.

Tumour organoids facilitate drug discovery - 20/07/2023

Drug screening for children with cancer using patient-specific miniature tumours

Standard drugs often don’t work in children and adolescents with recurrent cancer. Researchers from the Hopp Children's Tumour Centre (KITZ) and the German Cancer Research Center (DKFZ) in Heidelberg have been looking to open up new therapy options for those affected, and have cultivated individual miniature tumours from biopsy samples to test the effectiveness of a variety of drugs within a few weeks.

On Tuesday, July 18, 2023, the Tübingen AI Center held a symposium to celebrate its permanent establishment as a national AI center. Since July 1, 2022, it has received 20 million euros a year in funding from the federal government and the state.

The function of mast cells, which are part of the immune system, is still a mystery. Scientists at the German Cancer Research Center (DKFZ) have now shown in mice: mast cells function as a sensor that signals the animals to avoid antigens, including harmful allergens, and thereby protect themselves from health-threatening inflammatory reactions. The findings were published in the journal Nature.

Tübingen researchers describe connection between action and feeling of authorship - finding sheds light on delusions of external control in schizophrenia

This month marks the launch of an outstanding project integrating artificial intelligence (AI) and neuromedicine – the Hertie Institute for Artificial Intelligence in Brain Health (Hertie AI). Founded on February 1 at the Medical Faculty of the University of Tübingen, it will be the first institute in Germany to research the prevention and early diagnosis of diseases of the nervous system using artificial intelligence methods.

Cancer immunotherapies often fail because the immune cells are paralysed by immunosuppressive conditions in the tumor. Scientists from Heidelberg, Mannheim and Tel Aviv have now shown on tissue samples from patients as well as on tumor models in mice that the functionality of the immune defence depends decisively on certain helper cells.

Brain-computer interfaces are able to restore some mobility to paralyzed people by controlling exoskeletons. However, more complex control signals cannot yet be read from the head surface because conventional sensors are not sensitive enough. A collaboration of Fraunhofer IAF, Charité – Universitätsmedizin Berlin, University of Stuttgart and other industrial partners has taken up this challenge.

Researchers at the University of Freiburg Medical School led by Prof. Dr. Johannes Letzkus and the Max Planck Institute for Brain Research have discovered that a little-studied area of the brain, the "zone of uncertainty" or "zona incerta," communicates with the neocortex in unconventional ways to rapidly control memory formation.

Neurodegenerative diseases - 12/12/2022

Blood-based biomarkers allow the early prediction of Alzheimer's risks

Most dementia diseases develop insidiously and are only detected at an advanced stage. Researchers at the University of Heidelberg and the German Cancer Research Center (DKFZ) have now identified the glial fibre acidic protein (GFAP) in the blood as a promising biomarker that can be used to determine an increased risk of developing Alzheimer's disease up to 17 years before diagnosis.

An interdisciplinary research team at the University of Freiburg has found important clues about the functioning of the sensorimotor cortex. The new findings on neuronal activities in this brain area could be helpful for the further development and use of so-called neuroprostheses. These have an interface with the nervous system and are intended to help compensate for neuronal dysfunctions.

The newborn's immune system is suddenly confronted with microorganisms, food and numerous environmental influences at birth. How do the baby's immune cells prepare for this moment during pregnancy and birth? How do external influences shape the immune system immediately after birth? And what influence does an event like a premature birth have?

DZNE researchers discover link between the protein medin and Alzheimer's disease. The protein medin is deposited in the blood vessels of the brains of Alzheimer's patients along with the protein amyloid-β. DZNE Researchers have discovered this so-called co-aggregation. They have now published their observation in the renowned journal Nature.

The health of nerve cells is closely linked to the auxiliary cells that surround them, the so-called glial cells. It still remains largely unknown what role glial cells play in age-related diseases.

Heidelberg University scientists are to receive three ERC Synergy Grants – three highly endowed grants of the European Research Council – for pioneering research projects by several teams working in collaboration.

In the brain of adult mammals neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell. A research team led by Dr Francesca Ciccolini at the Interdisciplinary Center for Neurosciences (IZN) of Heidelberg University recently discovered a second stem cell population in the mouse brain.

Hearing loss - 29/06/2022

Innovative micro loudspeaker brings back hearing

Hearing loss often severely restricts the lives of those affected and can only be partially reversed with conventional hearing aids. The innovative hearing aid developed by Vibrosonic GmbH from Mannheim transmits sound vibrations directly to the eardrum and can thus almost completely restore the natural hearing experience.

Alzheimer's, Parkinson's and other neurodegenerative diseases are associated with inflammatory processes in the brain. German researchers have succeeded in identifying a group of proteins in the liquor that could provide information about such inflammatory processes. As so-called biomarkers, the proteins could help to better understand disease processes in the future and to test the effect of potential drugs against brain inflammation.

Microrobots have the potential to revolutionize medicine. Researchers at the Max Planck ETH Centre for Learning Systems have now developed an imaging technique that for the first time recognises cell-sized microrobots individually and at high resolution in a living organism. This is an important step towards precise control of the robots and their clinical translation.

In order to develop approaches for the prevention and treatment of Alzheimer's dementia in clinical trials, it would be helpful to be able to identify people with a particularly high risk of developing the disease. But which biomarkers can indicate an increased likelihood of disease early on in symptom-free people who actually develop Alzheimer's later?

In the field of optogenetics, scientists investigate the activity of neurons in the brain using light. A team led by Prof. Dr. Ilka Diester and Dr. David Eriksson from the Optophysiology Laboratory at the University of Freiburg has developed a new method to simultaneously conduct laminar recordings, multifiber stimulations, 3D optogenetic stimulation, connectivity inference, and behavioral quantification on brains.

Parkinson's disease is characterised by a slow, progressive loss of nerve cells in certain brain areas. The disease is still incurable and the exact causes are unclear. The dopamine deficiency in the brain can only be controlled to some extent in the initial phase of the disease. Basic research is being conducted in an attempt to unravel the mystery of Parkinson's disease.

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.

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.

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.
