Professor Peter Hofmann and his team at the Competence Center Electrical and Electronic (EE) Architecture at the Technische Universität Dresden (TU Dresden) have successfully developed the first self-organizing electronic components. These so called autonomous units form the basis for complex technical systems of the future. For this purpose, the scientists have adopted the knowledge of complex systems found in nature.
Organisms are structured according to the modular assembly concept – cells form tissue, tissue forms organs and these in turn form the organism. If individual cells die off, then the organism continues to function. This is because although the cells interact with their neighbouring cells, each individual cell is autonomous in its function. If necessary, it is even possible for other cells to step into the breach and take on a replacement function.
Engineers have been astonished about how effortlessly natural systems seem to adapt to new situations. As an example, a population of ants always finds the shortest way between food site and anthill without possessing a central instructional order. The mechanisms which take place in the human organism are equally fascinating, regarding for example injured skin cells or even entire organs which can regenerate themselves following an accident.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
