    It is a well-known fact that organic solar cells can convert light into electricity. What has been puzzling scientists – at least from a physicist’s point of view – is how exactly this is done. Researchers at the University of Würzburg have now succeeded in clarifying the process. A report on their work has been published in the scientific journal “Physical Review Letter”.

    Small satellites are an exciting option for space projects because their launch costs are low. Before using them for Earth observation or other tasks, however, there are still technical challenges to be met. This is what scientists of the University of Würzburg are currently concerned with.

    Calcium controls the beating of the heart and is a trigger for heart growth. But how does the heart know when to beat at a faster rate and when to start growing? Researchers have now found an answer to this question. Oliver Ritter, medical scientist at the University of Würzburg, was also involved in the studies.

    Turkish girls obediently do what their parents tell them to do. And they are eagerly awaiting to play their role as stay-at-home moms – in Germany, stereotypes like these about young Turkish women are quite common. But now, they have been disproved by a study of the University of Würzburg.

    There are still gaps in our knowledge about the origin and course of complex diseases like multiple sclerosis. Now, researchers of the University of Würzburg have studied the interaction between two important factors – with a clear result.

    Computers with no need of cooling? They haven’t come into existence yet. However, physicists of the University of Würzburg are paving the way for them: In the American scientific journal “Science”, the researchers now present a semiconductor that transmits electric current without heating up in the process.

    The inflammatory process in the brain of multiple sclerosis patients is triggered by their own immune system. However, there is one type of immune cells that seems to fight against the destructive progress – and might be used for therapeutic purposes in future.

    Umbilical cord blood has a great potential to heal many diseases. A new research cooperation examines how to grow as many stem cells as possible that are responsible for this effect. Initiator and spokesman of this cooperation is the Würzburg stem cell researcher Albrecht Müller. The Federal Government is funding the project with 1.2 million Euros.

    Due to inflammations, blood vessels may become leaky: Blood plasma leaks into the tissue which might involve serious complications. Researchers from the University of Würzburg have now developed a kind of molecular adhesive sealing hyperpermeable blood vessels.
