The department of physics at Bielefeld University receives a new high-performance compute cluster equipped with state-of-the-art graphics processors. The new facility will be used for research on properties of strongly interacting matter under extreme conditions of temperature and density. Such conditions existed in the early universe for only a fraction of the first second after the big bang but may still exist today in the interior of compact stars. The new high-performance compute-cluster is financed through a 1.9 million Euro grant of the Deutsche Forschungsgemeinschaft (DFG) and the state of North Rhine-Westphalia in Germany. The new facility will allow to significantly advance research projects which the particle physics group at Bielefeld University currently conducts within the Collaborative Research Center „Matter under extreme conditions“ (CRC-TR 211) – a research program of physicists at Bielefeld University, Technical University Darmstadt and Goethe University Frankfurt which also is funded by DFG. The inauguration of the new compute-cluster will take place on May 20, 2019, at 4pm in lecture hall 6 of the main building of Bielefeld University.[Weiterlesen]

How the Brain Integrates Sensory Input

Published on 30. April 2019
Bielefeld researchers publish study on the flexibility of sensory perception

Prof. Dr. Christoph Kayser
Hearing, sight, touch – our brain captures a wide range of distinct sensory stimuli and links them together. The brain has a kind of built-in filter function for this: sensory impressions are only integrated if it is necessary and useful for the task at hand. Researchers from Bielefeld University, Oxford University (Great Britain), and Aix-Marseille University (France) investigated this phenomenon of flexibility in perception, and have now published a study on their findings that appears in the scientific journal “Neuron” (29 April 2019). In their publication, the researchers reveal where sensory stimuli are integrated in the brain, and in which area of the brain this flexibility can be located. From Bielefeld University, Professor Dr. Christoph Kayser and Dr. Hame Park from the Cluster of Excellence CITEC were involved in the study.[Weiterlesen]

A poor deal for political education

Published on 18. April 2019
German schools place markedly less emphasis on political education compared to history or geography in their curricula. This is confirmed in the ‘2018 political education ranking’ presented by Professor Dr Reinhold Hedtke and Mahir Gökbudak from the Faculty of Sociology at Bielefeld University.[Weiterlesen]

Professor Dr Elena Esposito receives ERC Advanced Grant

Computers evaluate data that are then used to make predictions for medicine, insurance, or policing: what effect do these algorithms and their predictions have in society?  The Bielefeld academic Elena Esposito is receiving an ERC Advanced Grant from the European Research Council (ERC) for her sociological research on this topic. This grant is awarded to outstanding researchers who are already established, leading principal investigators in their field of research. It is worth 2.1 million euros over a period of five years. In the eleven-year history of the ERC Grants, Esposito is only the second person to bring an Advanced Grant in this field to Germany.[Weiterlesen]

New Algorithm Improves Control of Hand Protheses

Published on 28. März 2019
Bielefeld University exhibiting at 2019 Hannover Trade Fair

From 1-5 April, Bielefeld University will be exhibiting at the 2019 Hannover Messe (Hannover Trade Fair) with the Research Institute for Cognition and Robotics (CoR Lab) and the Cluster of Ex-cellence Cognitive Interaction Technology (CITEC). The researchers will be presenting their plat-forms and applications for machine learning. One example of their work is a new method for quickly adjusting hand prostheses: The system enables flawless control of hand prostheses – even if the measuring electrodes have moved on the user’s skin. This system is one of four presentations by Bielefeld University, one of which belongs to a new start-up company founded by CITEC researchers.

How antifreeze proteins make ice crystals grow

Published on 7. März 2019
International research team confirms twofold ability of molecules

Bacteria, plants, insects, or even fish use antifreeze proteins to protect themselves from the cold. The proteins block the growth of ice crystals. In a new study, a German–Israeli research team has confirmed that these proteins also possess an unusual second property: at low temperatures, they can promote rather than inhibit the growth of ice crystals. The study brought together researchers from Bielefeld University, the Hebrew University of Jerusalem, and the Weizmann Institute of Science in Rehovot (Israel). It is being published today (07.03.2019) in the ‘Journal of Physical Chemistry Letters’.[Weiterlesen]

Center for Advanced Studies explores crises in Latin America - and their solutions

Published on 1. März 2019
Bielefeld University coordinates joint project  / Main phase begins

Latin America is confronted with crises – from political unrest in Venezuela, the deforestation of the Amazon, violence against women (“feminicide”), the extreme divide between rich and poor, to the threat of a wall between the USA and Mexico. How do Latin American societies cope with crises? To answer this question, the German Federal Ministry of Education and Research (BMBF) is funding the CALAS cooperative project with a total of 12 million euros in the six-year main phase starting in March. Bielefeld University coordinates the "Maria Sibylla Merian Center for Advanced Latin American Studies in the Humanities and Social Sciences" (CALAS), headquartered at the University of Guadalajara, a strategic partner university of Bielefeld.

Astronomers publish new sky map detecting hundreds of thousands of previously unknown galaxies

Published on 19. Februar 2019

An international team of more than 200 astronomers from 18 countries has published the first phase of a major new radio sky survey at unprecedented sensitivity using the Low Frequency Array (LOFAR) telescope. The survey reveals hundreds of thousands of previously undetected galaxies, shedding new light on many research areas including the physics of black holes and how clusters of galaxies evolve. A special issue of the scientific journal Astronomy & Astrophysics is dedicated to the first twenty-six research papers describing the survey and its first results.[Weiterlesen]

The Algae’s Third Eye

Published on 18. Februar 2019
Scientists at the Universities of Würzburg and Bielefeld in Germany have discovered an unusual new light sensor in green algae. The sensor triggers a reaction that is similar to one in the human eye.

Just like land plants, algae use sunlight as an energy source. Many green algae actively move in the water; they can swim to the light or move away from it. For light perception they use special sensors (photoreceptors).[Weiterlesen]

Myth of Mona Lisa’s Magical Gaze Debunked

Published on 8. Januar 2019
Researchers from the Cluster of Excellence CITEC disprove scientific claim

In science, the “Mona Lisa Effect” refers to the impression that the eyes of the person portrayed in an image seem to follow the viewer as they move in front of the picture. Two researchers from the Cluster of Excellence Cognitive Interaction Technology (CITEC) at Bielefeld University demonstrate that, ironically enough, this effect does not occur with Leonardo da Vinci’s world-famous painting “Mona Lisa” – debunking a scientific legend. The researchers are presenting the results of their study in the scientific journal “i-Perception”.[Weiterlesen]
