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]

Bielefeld University signs the Magna Charta Universitatum

Published 13. September 2017
Vice-Rector Angelika Epple: ‘a logical step’

At the end of August, Angelika Epple, Vice-Rector for International Affairs and Diversity, signed the Magna Charta Universitatum on behalf of Bielefeld University during a festive ceremony in the Hungarian city of Pécs. The Magna Charta is a manifesto. By signing it, an institution agrees to abide by fundamental principles such as academic freedom and institutional autonomy. This year, eleven universities have signed; up to now, more than 800 universities have signed worldwide.[Weiterlesen]

At roughly 3.7 million Euros, the European Commission has now confirmed funding for a new programme in physics and biomedicine. Fourteen young scientists will be studying healthy aging under the microscope: They will be developing new optical procedures to study the liver with high-resolution microscopy. The goal is to find out how medical drugs affect the liver and how the organ changes with advancing age. The project DeLIVER, coordinated by Bielefeld University, will start in January 2018. This is now the seventh Marie Skłodowska-Curie Action (European training network for young academics) at Bielefeld University.[Weiterlesen]

Start of ‘Lehrkräfte Plus’: New perspectives for refugee teachers

Published 31. August 2017
Bielefeld University and the Bertelsmann Foundation offer the first ever programme of its kind in NRW

Twenty-five trained teachers who had to flee from their home countries have started the ‘Lehrkräfte Plus’ programme at Bielefeld University. Over the coming 12 months, 8 women and 17 men from Afghanistan, Armenia, Guinea, Iraq, Pakistan, and Syria will be gaining further qualifications that will potentially qualify them to work in schools in North Rhine-Westphalia (NRW). ‘Lehrkräfte Plus’ is a joint training programme at Bielefeld University in cooperation with the NRW Ministry of Education and Training and the State Coordination Office for Local Integration Centres in NRW. A further partner in the first ever programme of its kind in the federal state is the Bertelsmann Foundation.[Weiterlesen]

How a robot is teaching language to preschool children

Published 26. Juli 2017
Team at Cluster of Excellence CITEC present progress made on EU project

Researchers at Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC) are investigating what a robot needs to be able to do to teach a second language to preschool children. Since 2016, they have been researching whether and how social robots are suitable for teaching language. This research is part of the international project L2TOR, which is funded as part of the European Commission’s Horizont 2020 research program. A preliminary finding, according to the researchers: robots can motivate children to learn, and help them retain more vocabulary. On 13 July 2017, the Bielefeld project team demonstrated how the robot supports preschool kids in their learning.[Weiterlesen]

Unresponsive Wakefulness Syndrome: System to help patients communicate

Published 29. Juni 2017
Researchers at Cluster of Excellence CITEC launch collaborative research project

A new device is meant to help people with severe brain damage to communicate with others. The NeuroCommTrainer is supposed to understand brain signals, and enable the patient to respond with a “yes” or a “no” using electroencephalogram (EEG) measurements.  Best of all, the system helps train patients to control their brain activity in a targeted way. The NeuroCommTrainer project begins this month and is funded with 1.87 million Euro. Neuropsychologist Professor Dr. Johanna Kissler, of Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC), is leading the new research. Three universities, two companies, and the v. Bodelschwingh Foundation Bethel are working together on this project.[Weiterlesen]

Self-Learning Robot Hands

Published 8. Juni 2017
Cluster of Excellence CITEC presents new system that learns how to grasp objects

Researchers at Bielefeld University have developed a grasp system with robot hands that autonomously familiarizes itself with novel objects. The new system works without previously knowing the characteristics of objects, such as pieces of fruit or tools. It was developed as part of the large-scale research project Famula at Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC). The knowledge gained from this project could contribute to future service robots, for instance, that are able to independently adapt to working in new households. CITEC has invested approximately one million Euro in Famula. In a new “research_tv” report from Bielefeld University, the coordinators of the Famula project explain the new innovation.[Weiterlesen]

Smart Glasses Replace Construction Manual for Bird House

Published 13. April 2017
New development from CITEC researchers at Bielefeld University

Instead of having to tediously search for the right part with one hand and flip through the pages of the instruction manual with the other hand, the smart glasses from the Adamaas system display what step comes next directly in the user’s field of vision. This works for both operating a coffee machine and assembling a bird house. Professor Dr. Thomas Schack, Dr. Kai Essig, and Dr. Matthias Schröder further developed the smart glasses at Bielefeld University’s Cluster of Excellence Cognitive Interaction Technology (CITEC). Using “computer vision”, the system can autonomously recognize objects and steps of an activity, and based on this, the glasses show appropriate step-by-step support directly in the display of the glasses. The Bundesministerium für Bildung und Forschung (BMBF, Federal Ministry of Education and Research) is providing the project with 1.2 million Euro in funding. A film about Adamaas can now be viewed online.

Nanoinjection increases survival rate of cells

Published 1. März 2017

Physicists at Bielefeld University develop new methods for microscopic research

How do tumours grow? And how do bacteria transform harmless substances into medical agents? When biophysicists want to understand what is happening in living cells, they have to introduce fluorescent probes  or other foreign molecules. There are several ways to overcome the cell wall without causing the cell permanent harm. Physicists at Bielefeld University have developed a particularly gentle method for this: nanoinjection. In a new study to be found in ‘Scientific Reports’ published by ‘Nature’, they show that with this method, nine out of ten cells survive being injected with foreign molecules.
