Elastin as artificial muscle material - 02/03/2022

Artificial muscle from proteins for diverse future applications

As far as diversity and complexity are concerned, proteins are nature's smallest marvels. Biotechnologists have already used natural proteins as a basis for the development, bespoke design and production of artificial systems. This is what the livMatS cluster of excellence at the University of Freiburg has been doing. Researchers in the cluster have successfully produced an artificial muscle from elastin that functions autonomously.

A quantum sensor that can register nerve impulses without contact opens up new possibilities in prosthetics. Researchers at Fraunhofer IPA are developing together with the industrial partner Q.ANT the prototype of one Prosthetic arm that is controlled by neural commands like healthy limbs.

A research team led by PD Dr. Justus Marquet and from the Hertie Institute for Clinical Brain Research has developed two methods that allow muscle activity and training-induced adaptations to be measured completely contactlessly. The studies demonstrate that magnetic fields generated during muscle activity can be captured using highly sensitive quantum sensors - without the need for electrodes or skin contact.

Scientists at the Max Planck Institute for Intelligent Systems, the University of Tübingen and the University of Stuttgart under the Bionic Intelligence Tübingen Stuttgart (BITS) collaboration developed a biorobotic arm that can mirror human tremors.

Electrophysiology from cardiac pacemakers to drug discovery

Electrochemical reactions are involved in many processes in the human organism. Electrophysiology is the study of the central processes of electrical and chemical interaction and communication between neurons and muscle cells, including the transmission and processing of signals in the nerves and the subsequent contraction of the muscles. For example, electrophysiology studies examine the rhythm which which our heart pumps blood through the body.

Antibodies can improve the rehabilitation of people with acute spinal cord injury. Researchers at 13 clinics in Germany, Switzerland, the Czech Republic and Spain have investigated this with promising results. For the first time, it was possible to identify patient groups that displayed a clinically relevant treatment effect. A follow-up study will start in December 2024.

Dr. Stefan Schiller and Dr. Matthias Huber from the University of Freiburg’s livMatS Cluster of Excellence have succeeded in developing a muscle solely on the basis of natural proteins. The autonomous contractions of the material, which the researchers presented in the journal Advanced Intelligent Systems, can be controlled with the help of pH and temperature changes.

Augmented reality for visual orientation - 15/11/2023

Fall prevention with the help of balance-enhancing AR glasses

As we age, our eyesight deteriorates and we have increasing difficulties with orientation. This can lead to balance problems and fatal falls. A team led by Dr. Lorenz Assländer from the University of Konstanz is currently developing a prototype of augmented reality (AR) glasses that use superimposed patterns to facilitate visual orientation in space, thereby helping to improve balance control and prevent falls.

Zebrafish can completely replace damaged heart muscle cells: The affected organ becomes fully functional again. Researchers at Ulm University have discovered that a specific cell-to-cell communication signal helps them to cope better with replication stress. This stress inhibits tissue regeneration in humans and mammals as they age. In Zebrafish a signalling protein ensures that the cells of the damaged organ continue to divide and thus multiply.

Inflammation of the heart muscle, also known as myocarditis, is a serious consequence of a viral infection. This can impede the heart’s ability to pump blood in the long term. In a current study, researchers of the Faculty of Medicine of the University of Freiburg have discovered a new approach for treating myocarditis.

Bakteriocins - 24/05/2022

New antibiotic alternatives from soil bacteria

Bacteria are not the greatest of friends among themselves: many release antimicrobial substances into their environment in order to gain an advantage in their ecological niche. Researchers at the University of Ulm are making use of such bacteriocins by creating a genetically modified soil bacterium that can be used as a biotechnological platform organism to produce alternatives to antibiotics in pure form and in large quantities. The fact this…

Project SMARTGAIT - 13/09/2023

Safe and cost-effective analysis of neurological gait disorders with AI

Stroke, Parkinson's disease and multiple sclerosis often resulting in gait disorders in those affected. Gait analyses play a crucial role in the successful evaluation and therapy of such disorders. Current measurement methods are costly and time-consuming. The SMARTGAIT project is therefore developing an innovative AI-based system aimed at performing meaningful gait analyses with the help of simple smartphone video recordings.

3D tumor models, simulations of drug responses or plant stems used for testing heart stents: the 3R-BioMedicUS center at the University of Stuttgart is developing innovative biomedical approaches to improve preclinical studies, to be seen in the new video.

Researchers of the Heidelberg University, Heidelberg University Hospital (UKHD) and Heidelberg Institute for Theoretical Studies (HITS) have developed a synthetic peptide based on the natural protein S100A1, a nearly universal “fuel” for weakened hearts. The researchers combined computer-aided methods with lab studies to investigate the therapeutic effect of the so called S100A1ct peptide molecule.

The progression of multiple sclerosis (MS) can usually be slowed down with medication, but a cure is currently not possible. It is now established that Epstein-Barr viruses are involved in the development of MS. However, it is not known how the pathogens trigger the disease. The European Union is now funding the international research consortium BEHIND-MS as part of its HORIZON Europe program.

Treating a weak heart – for example after a heart attack – at the GP’s surgery with a single intravenous injection, without causing serious side effects: what sounds almost too good to be true is actually already under development. The Heidelberg-based biotech company AaviGen is working on a platform technology based on adeno-associated viruses that can help introduce therapeutic genes in a highly specific way into diseased heart muscle cells.

Inovedis GmbH’s innovative implant - 28/03/2023

Next-generation minimally invasive shoulder surgery

The treatment of shoulder injuries such as rotator cuff tears is one of the most common orthopaedic interventions. It is therefore quite surprising that the surgical procedure has not changed much for decades - although it is relatively complicated. The start-up Inovedis has now developed a completely new surgical technique based on an implant that can be performed simply, safely, quickly and cost-effectively with minimal stress for patients.

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.

Patients have 30 percent fewer serious side effects when medication doses are tailored to their genetic profile. This is what an international research consortium has found out, including the Dr. Margarete Fischer-Bosch Institute of Clinical Pharmacology at the Bosch Health Campus.

Using neuromedical artificial intelligence responsibly

Brain-computer interfaces are the latest developments in the neurotechnology field. They are used to record brain activity, which is then decoded with artificial intelligence techniques and converted into control signals for robots or computers. While this brings hope to severely paralysed people, it also implies risks due to the interest of companies like Google and Facebook in this type of data.

In the medicine of the future, tiny robots will navigate independently through tissue and medical instruments will indicate their position inside the body during surgery. Both require doctors to be able to localize and control the devices precisely and in real time. Scientists from the German Cancer Research Center (DKFZ) have now described a signaling method based on an oscillating magnet that can significantly improve such medical applications.

Together with colleagues from Israel and USA, HITS researcher Frauke Gräter investigates the effects of physical force on the collagen protein in two different animal model systems. Their goal is to measure the effects of mechanoradicals on the integrity of the tissue and the well-being of the organism, with impact on health and aging.
