Forgetting visualized in brain cells
There is a growing understanding of what happens in the brain when it is afflicted with Alzheimer's disease. Due to the death of nerve cells, people with Alzheimer's become increasingly forgetful, confused and disoriented. To date, Alzheimer's is incurable. But there are many approaches to getting the disease under control. One of these is an understanding of the neuronal processes that take place in our thinking organ. A team led by Prof. Paola Coan from the Department of Medical Physics and the Department of Radiology at the LMU Hospital in Munich has now gained new findings concerning this process with the help of X-ray phase-contrast computed tomography. Using this imaging technique, the scientists have gained unique insights into the ageing and neurodegeneration of brain cells in mice suffering from Alzheimer's disease.

Fast-moving processes in the microcosm
How incredibly short are attoseconds? And how can such ultrashort laser pulses enable innovative approaches, both now in the field of basic research and in the future in practical applications in the field of medical diagnostics? Prof. Ferenc Krausz explores these questions in his online lecture held in German.
What is a photon?
What is a photon? What sounds like a basic physics course turns out in Prof. Rempe's lecture to be a question not easily answered in the course of the history of science. Nevertheless, there is an amazingly catchword-like answer at the end of the video! The talk is in German language. However, the accompanying text and images are in English.
The world´s first functioning laser
On May 16, 1960, the laser was born. The device that Theodore Maiman built, still exists. Together with Ted Maiman's lab book, the historic laser is on display at the Max Planck Institute of Quantum Optics. Dr. Matthew Weidman, group leader of the attosecond metrology 2.0 team in attoworld, explains the individual components and the principle of how a laser works.
