Max Planck Society
"The Max Planck Society is Germany's most successful research organization. Since its establishment in 1948, no fewer than 18 Nobel laureates have emerged from the ranks of its scientists, putting it on a par with the best and most prestigious research institutions worldwide. The more than 15,000 publications each year in internationally renowned scientific journals are proof of the outstanding research work conducted at Max Planck Institutes – and many of those articles are among the most-cited publications in the relevant field."

Max Planck Institute for Nuclear Physics
The Max-Planck-Institut für Kernphysik (MPIK) is one out of 83 institutes and research establishments of the Max-Planck-Gesellschaft zur Förderung der Wissenschaften (MPG) (Max Planck Society for the Advancement of Science). The MPG was founded in 1948 as successor to the Kaiser-Wilhelm-Gesellschaft (established in 1911) and is committed to basic research.
The MPIK has been founded in 1958 under the leadership of Wolfgang Gentner. Its precursor was the Institute for Physics at the MPI for Medical Research led by Walther Bothe from 1934 to 1957. The initial scientific goals were basic research in nuclear physics and the application of nuclear-physics methods to questions concerning in the physics and chemistry of the cosmos. Since 1966 the MPIK is led by a board of directors. Today, the activities concentrate on the two interdisciplinary research fields quantum dynamics and astroparticle physics. (Source)
Theoretical models suggest that a large part of our universe is made up of dark matter - this has not yet been directly observed but the existence of dark matter is inferred from its gravitational effects such as the rotation of galaxies. Currently researchers work on directly detecting these particles instead of just predicting them theoretically. In this video MANFRED LINDNER describes the detector used by the team of the XENON Dark Matter Project: Essentially, it is a vessel filled with liquefied xenon and equipped with highly sensitive light sensors. When a particle enters the detector, it will generate light pulses which enable the researchers to pinpoint the exact location of the interaction as well as the type of particle. The high sensitivity of the instrument requires that extreme care is taken to eliminate any background signals.
