Study unveils how proteins control information processing in brain ANI | Updated: May 09, 2021 15:29 IST Halle [Germany], May 9 (ANI): A complicated interaction between different proteins is needed for information to pass from one nerve cell to the next. A team of researchers now managed to study this process in the synaptic vesicles, which play an important role in this process. The study led by a team at the Martin Luther University Halle-Wittenberg (MLU)T appeared in the journal Nature Communications. Several billion nerve cells communicate with each other in the body so that humans and other living beings can perceive and react to their environment. A host of complex chemical and electrical processes occur within a few milliseconds. Special messenger substances - known as neurotransmitters - are released at the synapses of the nerve cells. They transmit information between the individual nerve cells, explains Dr Carla ....

In addition to their structural function, some lipids also play a regulatory role and decisively influence cell growth. This has been investigated in a new study by scientists at Martin Luther University Halle-Wittenberg (MLU). The impact of the lipids depends on how they are distributed over the plasma membrane. The study was published in ....
E-Mail Credit: Panagiotis Kastritis A new method has enabled the natural structure of particularly large and complex enzymes to be revealed. Scientists at Martin Luther University Halle-Wittenberg (MLU) and TU Berlin have published their findings in the journal Cell Reports. They investigated a multi-enzyme complex that plays an essential role in metabolism and have discovered that it functions differently than previously thought. This will help scientists better understand certain diseases. Enzymes are a cell s biocatalysts. They accelerate chemical reactions in the body or ensure that these reactions even take place at all. As a result, they play an extremely important role in metabolism. Individual enzymes frequently form a complex with many subunits, as in the case of the pyruvate dehydrogenase complex. It occurs in all human, animal and plant cells, as well as in fungi and even in some bacteria. It is vital for energy production in cells, explains Dr Pana ....
Nanocomposite-Based Method to Create Highly Efficient Solar Cells Written by AZoNanoFeb 3 2021 A new technique to develop unique solar cells could considerably enhance their efficiency. Apart from being made of thin layers, the cells also include nanoblocks that are specifically arranged. This schematic representation shows the new structure: nickel oxide stripes run perpendicular to the actual material, serving as a passing lane for the electrons. Image Credit: Lutz Mühlenbein. This has been demonstrated by an international team of researchers led by the Martin Luther University Halle-Wittenberg (MLU), in a new study published in Nano Letters, a scientific journal. Solar cells available in the market are chiefly made of silicon. “ ....
Sponsored by Park SystemsJan 21 2021 Ferroelectrics found extensive uses in industrial applications because of their unparalleled electromechanical and electrical characteristics, for example, as actuators, sensors and capacitors [1], [2]. The suitability of ferroelectrics for modern communication technology is currently investigated by researchers, including 5G [3] and as active layers in photovoltaics [4, 5] among other applications [6]. Ferroelectricity is the consequence of an alteration in crystal symmetry during a phase transition. A sudden electrical polarization is introduced by an off-centering of the center ion or tilting of ionic groups. The crystal forms domains of parallelly aligned polarization in order to reduce the electrostatic energy. Without an external electric field, these domains are randomly oriented so that the macroscopic electrical polarization of the crystal stays fixed at zero (Figure 1a). ....
