No change in epoch has shaped the history of the human race like the Neolithic Revolution. The cultural transition from the gathering to the producing economy and the settling of communities took place around 11,000 years ago in the Near East, and reached central Europe around 7,500 years ago with the most significant Neolithic culture, the Linear Pottery Culture (LPC).
In controversial hypotheses, there have long been speculations attempting to explain the spread of the farming lifestyle from the Fertile Crescent to Europe: via idea transfer and acculturation, or even through different forms of infiltration by foreign civilizations in central Europe.
As a "neolithic package", the immigrants didn't just import new species such as domestic cattle and cultivated plants such as einkorn. By mixing with the local population, they also left traces in the genetic pool of central Europe. These traces are still evident today in the form of allochthonous DNA markers (mtDNA and Y-chromosome lineages).
The present interdisciplinary study analyzed samples of old DNA (aDNA) from a burial ground at the Early Neolithic Derenburg-Meeresstieg II site in the Middle Elbe-Saale region. The main finding of the study is the first molecular genetic proof indicating that the genetic profile of the early neolithic settlers from Derenburg has strong similarity with populations currently living in the Near East.
This means that, in this case as least, the first farmers immigrated to central Europe, instead of the hunter-gatherer populations previously prevalent in the region simply adopting a farming lifestyle. The genetic signa- tures also provide clues to the immigration route via South East Europe and the Carpathian Basin to Central Europe. Based on the information gained, it is now possible to reconstruct the settlement processes that have been so influential for early European history.
In addition to the actual historical findings, the conclusions drawn are also of major relevance to the current debate surrounding immigration: "Out of Africa" marks the beginning of the spread of the Homo species throughout the world over two million years ago. Humans are migrants by nature and it is clear that mobility and migration have been part of our behavior for all time. Increases in population density and the rise in hierarchy in society, a strongly regimented access to natural resources, human intervention in nature and war have gradually led to a rise in economic and social pressure within and between societies - with obvious results.
The emotionally charged discussion surrounding integration in Germany could be diffused if politicians used the tools available to demonstrate the joint roots shared by locals and immigrants. The task has surprisingly fallen to the discipline of archaeometry to make these connections clear. The most significant economic transformation in the history of the modern humans - the Neolithic Revolution - began in a region that is thought to be the birthplace of all Europeans, who spread outwards in waves of migration. These findings are not a completely unexpected development for traditional pre-history research. The scientific proof, however, has only just been found in a combined effort between archeology and anthropology.

Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...

The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
