    The tiniest fragments of bacteria are enough to trigger a defense response from plants to parasites. Researchers from the universities of Würzburg and Basel are now able to describe the molecular details of this response.

    Stimuli that regularly appear in connection with unpleasant situations are rated by people as negative, as would be expected. However, as researchers from the University of Würzburg are now showing, these stimuli can also subconsciously be rated positively – depending on the chronology of events.

    Durch Lichtpulse lässt sich der Spin eines Elektrons in eine genau definierte Position bringen. Physikern der Uni Würzburg ist es gelungen, die „Lebensdauer“ dieser Position deutlich zu verlängern – ein Fortschritt auf dem Weg zu Quantencomputern

    Ultrafast operation and high performance: This is what is expected of quantum computers. But there are still some obstacles to the technical implementation of this new type of computer. Physicists of the University of Würzburg report on their progress in this research area in "Nature Photonics".

    World first: chemists from the University of Würzburg have, for the first time ever, succeeded in creating a stable triple bond between the elements boron and oxygen. This success is reported in the leading journal “Science”.

    The photograph of a lit cigarette arouses a desire for nicotine in smokers. “Not necessarily,” say psychologists from the University of Würzburg. As they found out, some photographs even manage to trigger processes in the brain that are likely to suppress craving for this drug.

    Schließzellen der Pflanzen

    When plants protect themselves against drying out, processes take place in which calcium plays an important role, just as it does in muscle contraction in humans. Now for the first time, Dietmar Geiger and Rainer Hedrich from the Department of Molecular Plant Physiology and Biophysics at the University of Würzburg have shed light on exactly what happens.

    Flach und wabenförmig muss die Struktur aus Kohlenstoff oder Silizium sein, an der erstmals die Simulation einer so genannten Spinflüssigkeit gelungen ist. Dabei nehmen die Elektronen einen dynamischen Zustand ohne jegliche Ordnung ein. Thomas Lang, Phy

    Electrons in honeycomb structures can switch over to a very rare state, referred to as "spin liquid" by researchers. This has been demonstrated by physicists of the Universities of Würzburg and Stuttgart in a publication in the scientific journal Nature.

    The physical laws governing the world of atoms and electrons are different from those applicable to macroscopic phenomena. Scientists intend to make use of these laws, e.g. to develop new methods of storing and exchanging information. The necessary material for this is provided by Würzburg physicists.

    Angriff einer Immunzelle auf eine Nervenzelle

    With diseases such as multiple sclerosis, cells of the immune system attack nerve cells in the brain and spinal cord. Scientists from the University of Würzburg have now managed to observe and describe this attack in detail.

    Die roten Flächen mit gesundem Gehirngewebe zeigen es: Mäuse ohne T-Zellen (Rag1-/-) entwickeln kleinere Schlaganfälle als normale Mäuse (WT). Versorgt man Mäuse, denen die T-Zellen fehlen, von außen mit T-Zellen, dann werden beim Schlaganfall wiede

    Strokes are less damaging if certain immune cells are absent in the blood. This previously unknown mechanism will be presented by researchers from the University of Würzburg in the science journal “Blood”.

    When a patient has lost his ability to communicate with his environment, is it possible that he might have retained some level of consciousness? And which technique could assist him in expressing his requests or thoughts? These questions are to be tackled by a new research network coordinated by psychologist Andrea Kübler.

    Zelle aus einem Blatt der Ackerschmalwand (Arabidopsis thaliana), befreit von ihrer Zellwand (A). Wird auch noch die Zellmembran entfernt, bleibt die große Vakuole übrig (B), die dann für Pumpstrommessungen mit der Patch-Clamp-Technik zugänglich ist.

    If it were not for proton pumps in plants, there would be no acid in wine. These pumps are important generally for plant vitality, as researchers from Würzburg and Heidelberg report in the renowned journal “Proceedings” of the Academy of Sciences in the USA.
