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 the Science of Human History
"The Max Planck Institute for the Science of Human History conducts basic research in modern analytical methods with the aim of an integrated science of human history. It bridges the gap between history and natural sciences. Scientists from different disciplines such as biology, linguistics anthropology and history jointly work on innovative methods, in particular in the fields of cutting-edge genetic sequencing, bioinformatics, language documentation, and phylogeography. This thoroughly integrated, interdisciplinary approach will allow long-standing questions about human history that were previously deemed difficult, or even completely intractable, to be resolved."

Dental calculus, a calcified form of tooth plaque, can give detailed information about the diets, diseases and lifestyles of past humans. CHRISTINA WARINNER discusses how she gains new knowledge about the way human beings used to live, what they ate, and how their microbiome has evolved. Dental calculus is the richest known source of ancient DNA in the archaeological record, and it is the only part of the body that fossilizes during life. In this video, she explains how emerging technologies in genomics and proteomics are contributing to groundbreaking discoveries about past human health and diet. By combining genetic and protein data, she describes how ancient infections leave behind sufficient traces to reconstruct entire pathogen genomes, as well as a detailed snapshot of host immune response. She explains how studies of ancient dental calculus will help us understand how our microbiome has evolved and why understanding the human ancestral microbiome may shed light on current chronic health problems.
