On Sunday (10.12.2017), the Americans Jeffrey C. Hall, Michael Rosbash, and Michael W. Young were awarded the Nobel Prize for Medicine and Physiology for their research on the biological clock. They discovered the molecular mechanisms controlling biological rhythms. A new ‘research_tv’ report describes how scientists at Bielefeld are also advancing research on the biological clock. The biochemist Professor Dr. Dorothee Staiger from Bielefeld University explains what the three Nobel Prize winners have achieved and reports on the discoveries her research team has made together with collaborators.[Weiterlesen]

Spin current from heat: new material increases efficiency

Published 20. November 2017
Study published by physicists from Bielefeld University

Electronic devices such as computers generate heat that mostly goes to waste. Physicists at Bielefeld University have found a way to use this energy: They apply the heat to generate magnetic signals known as ‘spin currents’. In future, these signals could replace some of the electrical current in electronic components. In a new study, the physicists tested which materials can generate this spin current most effectively from heat. The research was carried out in cooperation with colleagues from the University of Greifswald, Gießen University, and the Leibniz Institute for Solid State and Materials Research in Dresden. Their findings are being published today (20.11.2017) in the research journal ‘Nature Communications’.[Weiterlesen]

In December, the Nobel Prize for Medicine and Physiology will be awarded for the identification of genes that control the biological clock. The honoured academics examined fruit flies to investigate the molecular basis of biological rhythms. Biochemist Professor Dr. Dorothee Staiger (Photo) of Bielefeld University has been investigating the biological clock of plants for twenty years. Her team has now published a new study in the research journal “Genome Biology”. One finding: not only the biological clock, but also a protein acting as an "auxiliary clock" ensures that recurring routines take place in the cells.[Weiterlesen]

A Specialist in Sensory Integration

Published 2. November 2017

Dr. Christoph Kayser accepts professorship at Bielefeld University / 2 Million Euro Funding from European Research Council

Whether it is the lively activity of a festival, the vibe at the beach, or the chaos at the scene of an accident, the brain classifies these situations at lightning speed. To do this, the brain continuously sorts and combines the information it receives through the eyes, ears, and other sensory organs. Professor Dr. Christoph Kayser, a biologist and mathematician, researches how, and where in the brain, sensory information is integrated. Prof. Dr. Kayser previously headed a research group at the University of Glasgow (Great Britain), and has now accepted a professorship in Cognitive Neuroscience at Bielefeld University. His research is well known internationally: the European Research Council (ERC) provides 2 million Euros to fund his work through 2020.

A Social Robot and Data Sonification in the Caring Apartment

Large-scale project at Cluster of Excellence CITEC nearing completion

What makes an intelligent apartment socially competent, allowing it to provide optimal support to its guests? Researchers at Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC) have been investigating this question in a large-scale project.  The main result of this project has been the creation of an intelligentapartment in the CITEC Building, which can be used around the clock as a research apartment. Among the innovations developed by the researchers include an “emotional” robot head, a sound-based energy consumption notification system, and a light signaling system in the kitchen. The project, called the “caring apartment,” will officially be concluded at the end of October. The researchers are presenting the results of their project this week at the international conference “Human Agent Interaction” (HAI), which is being held at CITEC. A new video gives a glimpse into the research on the cognitive robot service apartment.[Weiterlesen]

New Sensor System Ensures a Safe Harvest

Published 27. Oktober 2017

Cluster of Excellence CITEC and the company CLAAS introduce research

Tractors and combine harvesters are frequently operated on difficult terrain. Crops such as canola and corn grow at different densities; the field is sometimes muddy and is rocky at other times; and plants often obscure the view of potential impediments. In order to enable harvesting machinery to efficiently and safely harvest crops despite changing conditions, a new system for environment detection has been developed by Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC) and CLAAS, an agricultural machinery manufacturing corporation located in Harsewinkel, Germany. The joint project is being funded as an innovation project within the it’s OWL technology network. The results of the project have been presented on 24 October at a workshop in the CITEC Building.[Weiterlesen]

Psychologist at Bielefeld University presents successful treatment method

They are suffering from nightmares, flashbacks, depression, or anxiety disorders: refugees coming to Germany from conflict areas are frequently traumatized. ‘Realistic estimates state that up to 40 per cent of refugees have mental problems. Hence, for the period since 2015, we are talking about several hundred thousand people who are in real need of psychological support,’ says Professor Dr. Frank Neuner from Bielefeld University. The psychologist is one of the team responsible for developing ‘Narrative Exposure Therapy’ (NET]. It has been applied over the last 15 years in conflict zones from East Africa to Sri Lanka. What is special about this therapy is that it shows success after only a few sessions. In a new ‘research_tv’ programme at Bielefeld University, Frank Neuner talks about NET and explains the consequences of leaving refugees without treatment.[Weiterlesen]

Dancing electrons lose the race

Published 22. September 2017

Bielefeld physicists publish in the research journal ‘Science’

Atoms emit electrons when a material is irradiated with light at a sufficiently high frequency. Previously, physics had assumed that the motion of these photoelectrons is determined by the properties of the material. In a new study, physicists at Bielefeld University have shown that it is the interplay of the electrons within the atom that is decisive. ‘Dancing’ electrons orbit the nucleus of the atom and require more time than other electrons that shoot out in straight lines. The Bielefeld researchers are the first in the world to confirm the existence of this delay mechanism  in a solid. The study has been published this Friday (22.09.17) in the scientific journal ‘Science’.[Weiterlesen]

Filtering molecules from the water or air with nanomembranes

Published 14. September 2017
Bielefeld physicists producing and carrying out research on extra-thin foils

Free-standing  carbon membranes that are a millionth of a millimetre thin: these are a special research field of Professor Dr. Armin Gölzhäuser from Bielefeld University and his research group. The nanomembranes can serve as ultrafine filters and as a protective layer. The Bielefeld physicists have registered several patents for manufacturing such molecular foils. In their research, they are analysing which properties the nanomembranes possess – as a basis for future applications. In a new film produced by Bielefeld University’s ‘research_tv’, Armin Gölzhäuser explains what makes the membranes such multi-talents and assesses how significant they may become for the purification of water.  [Weiterlesen]
