Neutrinos are the most common elementary particles in the universe—and yet, of all particles, we know the least about them!
They are the only elementary particles that are uncharged and interact only through the weak force. But why can neutrinos transform from one type into another? What does all this have to do with their mass? And how can we measure this mass?

Animal experiments conducted on storage rings have shown for some time that healthy tissue becomes significantly more resistant to radiation doses when spatially microstructured X-rays are used. This makes it possible to effectively target cancer cells and minimize the negative side effects of radiation therapy.
Due to the size of the storage rings—at least several hundred meters in circumference—it has not been possible to date to exploit this effect in clinical practice. Here, the “line-focus X-ray tube” developed in Mainz has demonstrated that the transfer to clinical practice could be achieved with a system nearly two orders of magnitude smaller. The presentation will introduce some of the methods derived from Theoretical Nuclear Physics and accelerator physics and describe the challenges that still lie ahead.

Have you ever wondered how the world around you came to be? How did the universe evolve into what we see today? Thanks to two revolutionary scientific developments of the 20th century—quantum field theory and the general theory of relativity—we are able to understand the evolution of the early universe and make quantitative predictions that can be tested with increasingly precise experiments. Cosmology, once a field of speculation, has evolved into a precision science. Nevertheless, many questions remain unanswered, for we are only at the beginning of an exciting journey of discovery.

Are the fundamental objects of our world point-like particles …
… or do we need one more dimension?
