Researchers from the University of Zurich have demonstrated that the thickness of the left brain areas is reduced while the areas on the right hand side that compensate for the injury increase in size. The fine motor skills of the compensating hand also improve considerably. The results of the study are significant for the treatment of strokes, in which the immobilization of an arm or a leg is central.
What happens in the brain of right-handed people if their dominant hand is immobile for two weeks? This is the question addressed in the latest study led by Professor Lutz Jäncke and the Trauma Surgery Department at Zurich University Hospital. For the study, ten right-handed people with broken upper right arms were examined. Because of the plaster or sling, the test people’s right hands were restricted to little or no movement for fourteen days.
Therefore they used their left hands for daily activities such as eating, brushing their teeth or writing. The participants were given two MRI brain scans: one 48 hours after injury and a second 16 days after the arm was immobilized. Based on the scans, the neuropsychologists analyzed the test people’s gray and white brain matter. They calculated the thickness of the cerebral cortex and the values of the corticospinal tract and measured the fine motor skills of the left, free-moving hand.

Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.

Microelectronics as a key technology enables numerous innovations in the field of intelligent medical technology. The Fraunhofer Institute for Biomedical Engineering IBMT coordinates the BMBF cooperative project "I-call" realizing the first electronic system for ultrasound-based, safe and interference-resistant data transmission between implants in the human body.
When microelectronic systems are used for medical applications, they have to meet high requirements in terms of biocompatibility, reliability, energy...
Thomas Heine, Professor of Theoretical Chemistry at TU Dresden, together with his team, first predicted a topological 2D polymer in 2019. Only one year later, an international team led by Italian researchers was able to synthesize these materials and experimentally prove their topological properties. For the renowned journal Nature Materials, this was the occasion to invite Thomas Heine to a News and Views article, which was published this week. Under the title "Making 2D Topological Polymers a reality" Prof. Heine describes how his theory became a reality.
Ultrathin materials are extremely interesting as building blocks for next generation nano electronic devices, as it is much easier to make circuits and other...
