Physicists at the RUB, working in collaboration with researchers from Grenoble and Tokyo, have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a semiconductor and to select a single electron from one of them using a sound wave, and then to transport it to the neighbouring QD. A single electron "surfs" thus from one quantum dot to the next like a fish on a
How Researchers Teach Bacteria New Behaviors
Researchers working in the field of synthetic biology use components that occur in nature and combine them in a new way. This is how bacteria acquire functions that they hadn't previously possessed. This offers great potential for biotechnology. Bacteria respond to temperature and metabolic products
Folding Molecules into Screw-shaped Structures
Artificial molecules are like sheets of paper. Chemists can fold them into specific shapes. Transferring the shape of one molecule to another, however, poses a significant challenge. An international research team describes the methods of winding up molecules into screw-shaped structures in the journal Angewandte Chemie. With the aid of artificial molecules, the researchers imitated the principles underlying the assigning a specific function to biomolecules in nature.
Novel Optogenetic Tool
Blue on, yellow off: using different-coloured light, researchers are able to switch signalling pathways in the brain on and off.
Brain Processes Social Information at High Priority
Our brain automatically pays great attention to everyday actions linked to a social context. Researchers from Bochum have verified this fact with the aid of hypnosis. Brain is sensitive for social information
RUB Researchers Use Cyanobacteria for the Production of Chemicals
Prof Dr Robert Kourist from the junior research group Microbial Biotechnology and Dr Marc Nowaczyk from the Chair for Plant Biochemistry have succeeded in genetically modifying cyanobacteria, thus creating cells that produce enzymes for the manufacture of basic and fine chemicals. The bacteria also supply the energy required by the enzymes - by performing photosynthesis. A report on their work has been published in the renowned journal Angewandte Chemie.
When Memories Age
When we remember events which occurred recently, the hippocampus is activated. This area in the temporal lobe of the brain is a hub for learning and memory. But what happens, if we try to remember things that took place years or decades ago? Neuroscientists at the Ruhr-University Bochum and the Osaka University have been able to give some answers to this question. They reveal that the neural networks involved in retrieving very old memories are quite distinct from those used to remember recent
New Electrode for Ion Concentration Analysis
For the purpose of blood analyses and industrial tests, it is often necessary to measure the concentration of specific ions. At present, the relevant devices are large and cannot be produced at low costs. A new dry electrode could change all that. Mini analysis systems for ion concentrations have posed a considerable challenge for developers to date. They had to find a compromise between size, costs and reproducible results.
Novel Blood Test for Alzheimer's Diagnosis
Today, Alzheimer's disease is diagnosed too late. In collaboration with a research team at the university and German Center for Neurogenerative Diseases (DZNE) in Göttingen, Researchers at Ruhr-Universität Bochum (RUB) have developed a blood test that may potentially facilitate detection of Alzheimer's at an early stage. It is based on an immuno-chemical analysis using an infrared sensor. The sensor's surface is coated with highly specific antibodies which extract biomarkers for Alzheimer's from the blood or the cerebrospinal fluid, taken from the lower part
