When light hits organic molecules, it triggers processes that are of considerable interest to scientists. But the individual steps of the reaction are very hard to identify. A study group at the University of Würzburg has now accomplished this task – with a sophisticated approach.


03.04.2013 Surprising Findings in Fish Genome

It is a popular aquarium fish: the platyfish, Xiphophorus maculatus. It is valued by researchers as an important model organism in the search for genetic trigger factors of skin cancer. Together with colleagues from the USA, University of Würzburg biochemist Manfred Schartl has decoded the genome of this fish species.


03.04.2013 Mit Stammzellen gegen Arthrose

Kann eine Therapie mit Stammzellen Patienten helfen, die an einer Arthrose leiden? Das untersuchen Mediziner der Universität Würzburg. In dieser bundesweit ersten Phase-1-Studie werden sie insgesamt sechs Patienten behandeln. Die derzeitigen Ergebnisse klingen vielversprechend.


02.04.2013 Suddenly Magnetic

The fact that non-magnetic tin atoms on a silicon substrate suddenly become magnetic is attributable to regularly ordered patterns of electron spin. (Graphics: Jörg Schäfer)

It came as a surprise: If tin atoms are arranged on a silicon substrate in a special way, the material becomes magnetic. University of Würzburg physicists have successfully conducted such an experiment. This research might open up a new way of processing information.

The blue-light pigment cryptochrome is important in regulating the circadian clock of many organisms. Scientists have now discovered that in the fruit fly Drosophila it also intervenes in the visual process. The central experiments involved were conducted at the University of Würzburg’s Biocenter.


22.03.2013 Festgala für ausgezeichnete Physiker

Ende 2012 hatte die Fundamental Physics Prize Foundation die Preisträger des Physics Frontiers Prize bekannt gegeben. Darunter war auch der Würzburger Experimentalphysiker Professor Laurens Molenkamp. In einer Gala in Genf wurde der Preis jetzt offiziell übergeben.


15.03.2013 Can the canine distemper virus infect humans?

The structural model shows how, after just one mutation, an envelope protein (pink) of the canine distemper virus can bind to the CD150 receptor (blue) of human immune cells. This would give the virus access to the cell interior. (Graphic: Bieringer et al. PLoS ONE 8(3): e57488)

Eradicate measles – this is one of the goals of the World Health Organization. If it succeeds, this might open the door to another pathogen: the canine distemper virus.


14.03.2013 Fibromyalgia: First Proof Found

The fibromyalgia syndrome is characterized by chronic pain in several body regions. Researchers at the University Hospital of Würzburg now have found clear proof of damage to patients' small fibers. (Foto: Benjamin Thorn / pixelio.de)

Fibromyalgia has a reputation as a mysterious illness: The symptoms are diverse, the causes are unknown and the diagnosis is difficult. For the first time, researchers at the University Hospital of Würzburg now have found clear proof of damage to patients' small fibers.


13.03.2013 Tapeworms: Genome Mapped

In this stage, the larva of a fox tapeworm enters the fox that has eaten an infected mouse. In the centre of the globular structure, we can see more clear-cut bends: This is the set of hooks the tapeworm uses to attach to the intestinal wall of the fox. (Photo: Klaus Brehm)

For the first time, scientists have mapped the entire genome of four tapeworm species. Their publication in "Nature" magazine reveals new weak spots of the parasites – they seem to be susceptible to standard cancer drugs.


08.03.2013 Good Grades for Gifted Student Classes

For quite a few years now, special classes for gifted students have been implemented at grammar schools in the German states of Bavaria and Baden-Württemberg. Researchers from Würzburg, Trier and Erlangen have studied them to determine whether they live up to expectations. The results are definite.


07.03.2013 Dialysis: Blood Protein as a Risk Factor

Christiane Drechsler and Professor Christoph Wanner from the University Hospital of Würzburg have gained new insight into the treatment of dialysis patients. (Photo: Robert Emmerich)

A modified blood protein increases the mortality risk in patients undergoing dialysis treatment. This has been reported by researchers from Würzburg and Boston in the journal "Science Translational Medicine". They also have an idea about how the risk factor might be successfully dealt with.

Viele Kulturpflanzen müssen von Insekten bestäubt werden, um hohe Erträge zu bringen. Dabei spielen Wildbienen eine weitaus größere Rolle als bislang angenommen. Das berichtet ein internationales Forschungsteam in „Science“.


28.02.2013 News on Immunotherapy

T lymphocytes are cells of the immune system with the ability to destroy cancer cells. Their activity is reflected in the graphics, which shows an increase in the death of tumor cells on the right-hand side. (Picture Matthias Wölfl)

Some T cells of the immune system are natural enemies of cancer cells. How they are prepared for their deployment in the organism appears to be very decisive in determining their effectiveness in cancer treatment.


26.02.2013 Communication in an Indirect Way

If a monolayer of organic molecules is deposited on a metal substrate, the conductivity of the organic material is significantly enhanced – as University of Würzburg physicists have just found out. (Graphics Peter Puschnig, Michael Wießner)

Organic materials are comparatively poor conductors of electricity. Under certain conditions, however, this can change significantly. University of Würzburg physicists have now experimentally determined how exactly such a change in conductivity works in a two-dimensional layer.


21.02.2013 Photonen im Paartanz

Durch resonante Anregung senden Halbleiterquantenpunkte auf Knopfdruck ununterscheidbare Photonen aus. (Grafik: Lehrstuhl für Technische Physik)

Photonen, die in ihrer Eigenschaften absolut identisch sind, sind ein Schlüssel für Quantennetzwerke und Quantencomputer. Einem internationalen Wissenschaftler-Team ist jetzt die Produktion solcher Photonen auf Knopfdruck gelungen. Physiker der Uni Würzburg haben den zentralen Baustein geliefert.
