Max Planck Institutes and Experts

With the exception of humans, chimpanzees show the most diverse and complex tool using behaviors of all existant species. Primatologists at the Max Planck Institute of Evolutionary Anthropology are using new research methods to study chimpanzee tool use in the dense forests of the Congo Basin. They are discovering complex technological skills among these apes that expand current perceptions of chimpanzee cognition and material culture.

Researchers at the Max Planck Institute for Social Anthropology examine how biomedicine is shaped through its engagements in Africa. Biomedicine is regarded as a circulating set of technologies, practices, and ideas that – as a by-product of prevention and healing – links individual bodies to the political order. Africa is central for understanding global shifts in the making of social, political, and juridical forms of governance because the continent is marginalised in the global political economy and thus represents a site of intense conflict and experimentation.

Life in concentrated brines under extreme conditions of nutrition requires extreme adaptation. By molecular and functional analysis of cellular constituents of halophilic archaea it is possible to gain insight into the biology of these fascinating organisms on a systems level of the cell.

Nature hasn’t made things easy for mammals. Admittedly, as any other vertebrate – they develop from a fertilised egg, but unlike fish or frogs, the embryo cannot prosper by itself. Only if it succeeds, after having divided a couple of times, in implanting with its outer cells in the womb, its inner cells will create a foetus. It has long been unclear as to when and how the cells of an embryo pursue various lineages. Scientists of the MPI for Molecular Biomedicine in Münster have now advanced a great deal towards unravelling this mystery.

The atomic structures of a bacterial succinate:quinone oxidoreductase and of mechanistically interesting variants have been determined by X-ray crystallography. Together with complementary functional studies, these results have yielded unequivocal evidence for a novel type of essential transmembrane proton transfer driving transmembrane electron transfer in this protein complex.
