Max Planck Institutes and Experts

The study of similarities and differences in behavior and physiology between humans and great apes allow for a better understanding of human evolution. Researchers of the Department of Primatology at the Max Planck Institute for Evolutionary Anthropology in Leipzig investigate with the help of behavioral observations and the measurement of physiological parameters in the urine of free living apes how competition and cooperation influence the excretion of a number of hormones.

In a successful global institution committed to the universal interest of humankind, national states and their demands remain important and have in recent years taken the shape of a North-South conflict. A research group at the Max Planck Institute for Social Anthropology studies the decision-making processes of the UNESCO World Heritage institutions and the local consequences of World Heritage inscriptions in the celebrated historical cities of Kyoto, Istanbul, Melaka and Xiʼan.

Using state-of-the-art technology and sophisticated data analysis tools, a team from MPIA has developed a new and powerful technique to directly determine the mass of a galaxy hosting an active supermassive central black hole at a distance of nearly 9 billion light-years from Earth. This pioneering method promises a new approach for studying the co-evolution of galaxies and their central black holes, which typically relies on mass determinations.

Astronomers at the Max Planck Institute for Astronomy have measured for the first time the alignment of magnetic fields in gigantic clouds of gas and dust in a distant galaxy. The results suggest that such magnetic fields play a key role in channelling matter to form denser clouds, and thus in setting the stage for the birth of new stars. The work was published in the November 24 edition 2011 of the journal Nature.

In the collision of neutron stars, the extremely compact remnants of evolved and collapsed stars, two light stars merge to one massive star. The newly-born heavyweight vibrates, sending out characteristic waves in space-time. Model calculations at the Max Planck Institute for Astrophysics now show how such signals can be used to determine the size of neutron stars and how we can learn more about the interior of these exotic objects.
