Heidelberg Researchers Investigate Cytotoxic Effect of Ebola Virus
Heidelberg Researchers Investigate Cytotoxic Effect of Ebola Virus
In the course of basic research in membrane biochemistry scientists at Heidelberg University have gained new insight into the cytotoxic effect of the Ebola virus. Employing biochemical and cell biological methods they have shed light on the molecular relationships between the Ebola glycoprotein and its role in mediating cytotoxicity.

Global collapse in huge songbird population
Global collapse in huge songbird population
With its canary-yellow colouring, the yellow-breasted bunting - about the size of a sparrow - is one of the more striking species of songbirds. Until a few years ago it was one of the commonest birds found in northern Europe and Asia. Since then, however, ornithologists have recorded sharp declines in many regions.

The Regulating Hand in Ribosome Formation
Ribosomes, which use a fixed genetic programme to manufacture cell proteins, also form according to a strict hierarchical plan. In an interdisciplinary approach, the research teams of Ed Hurt of the Heidelberg University Biochemistry Center (BZH) and André Hoelz of the California Institute of Technology (Caltech) in Pasadena (USA) have decoded the mechanism that regulates this process.

Signal replicas make a flexible sensor
LMU researchers have shown how signals from the spinal cord adjust the sensitivity of hair cells in the inner ear to accommodate shifts in head position associated with active locomotion - thus ensuring that balance is maintained. Fluorescence image showing two nerves (stained in red and green), which are responsible for transmitting information from the hair cells to the brain and from neurons (small green dots) that alter hair cell sensitivity, respectively.

New Findings: Variability Helps Mammals to Become Invasive From the time humans began discovering and conquering new continents, they also started transporting animals and plants around the world and releasing them in locations where they had never been before. Most of these alien species died out quickly, but many established populations and some even multiplied and became invasive, causing tremendous economic and environmental harm.

Revolution averted
Who came first - sponges or comb jellies? A new study by an LMU team reaffirms that sponges are the oldest animal phylum - and restores the classical view of early animal evolution, which recent molecular analyses had challenged. The answer to the question of whether the sponges or the comb jellies (also known as sea gooseberries) represent the oldest extant animal phylum is of crucial importance to our understanding of organismic evolution.

Invasion to the inside
In order to multiply, influenza viruses are dependent on cells of a human or animal body. They board those cells, for example all along the lung surface, and their genetic material migrates into the nucleus, where it is replicated. As a result, new viruses come to life. A team led by scientists from the Cells-in-Motion Cluster of Excellence (CiM), University of Münster, has now, for the first time, succeeded in visualizing structures of the viral genome inside of human cells by light microscopy.

Schleimige Computer: Künstlerisch-wissenschaftliche Studie zu Schleimpilz-Forschung
Der Computer der Zukunft könnte um einiges schleimiger sein als die Silizium-Geräte, mit denen wir es heutzutage zu tun haben. Genau damit befasst sich die Studie, die Theresa Schubert (Bauhaus-Universität Weimar, Professur Gestaltung medialer Umgebungen) und Andrew Adamatzky (University of the West of England, Bristol) in dem renommierten Journal 'Materials Today' veröffentlicht haben.

Unique snapshot of an enzyme in action
Unique snapshot of an enzyme in action
Göttingen scientists unravel fundamental mechanisms of biochemical reactions (pug) Enzymes are the molecular catalysts of life performing vital metabolic functions in every cell. To date, it has been speculated that enzymes literally bend and break their substrates during biochemical reactions. For the first time, scientists at the Göttingen Center for Molecular Biosciences (GZMB) succeeded in experimentally confirming this hypothesis with certainty.

Spin-off Eliminates Animal Testing
Chemical, medication and cosmetic manufacturers are obligated to test their products for possible health risks using appropriate means, as stipulated by various European guidelines. Animal testing is frequently used to determine the dangers of such products to the human eye. Aside from ethical reasons, arguments against this form of testing include high costs, delays due to approval procedures, and concerns whether the results from animal testing can be extrapolated safely to human beings.

The Import Business of Cellular Power Plants Freiburg Scientists Reveal Newly Discovered Communication Path in Cells
Scientists from Freiburg's two Excellence Institutions Centre for Biological Signalling Studies (BIOSS) and Spemann Graduate School of Biology and Medicine (SGBM) have discovered a new signaling path in cells: a mechanism which enables the transport of proteins into mitochondria to be adjusted depending on the current metabolic state of the cell.

Proteins Need Chaperones
Freiburg Biochemist Describes Newly Discovered Processes in Production of Proteins in 'Nature' Freiburg, 07.01.2011 The chaperone ZRF1 helps the ribosome to regulate protein synthesis. A new study shows that it also participates in the regulated translation of DNA segments into transcripts in the nucleus.

No Phenylketonuria in the Moss Physcomitrella patens
International Team Discovers New Metabolic Pathway Freiburg, 14.12.2010 Phenylketonuria is the most common metabolic disease in humans. It occurs when the so-called PAH gene is defective, thus preventing the amino acid phenylalanine from being metabolized to the amino acid tyrosine. This leads to an accumulation of phenylalanine and to severe developmental disorders.

Do traffic lights in the brain direct our actions
Delayed inhibition between neurons identified as possible basis for decision making Freiburg, 25.11.2010 The timing of exciting (red curve) and inhibiting (blue curve) signals could be a way to control the ‘traffic flow' of activity in the brain. (Illustration: Bernstein Center Freiburg) In every waking minute, we have to make decisions - sometimes within a split second.

A new Concept in Microscopy:
Self-reconstructing Laser Beams - published in ‘Nature Photonics' Researchers at the University of Freiburg are developing a microscope with illuminating beams that actively refocus in a light-scattering medium. Freiburg, 12.10.2010 It's a familiar situation for all car drivers. In the autumn, when the roads are foggy, visibility drops below 50 metres.
