Although some historical accounts may support this view, a new article by Dr. Michael Frachetti (Washington University, St. Louis) illustrates a considerably different image of prehistoric pastoralist societies and their impact on world civilizations more than 5000 years ago.
In the article, recently published in the February issue of Current Anthropology, Frachetti argues that early pastoral nomads grew distinct economies across the steppes and mountains of Eurasia and triggered the formation of some the earliest and most extensive networks of interaction in prehistory. The model for this unique form of interaction, which Frachetti calls "nonuniform" institutional complexity, describes how discrete institutions among small-scale societies significantly impact the evolution of wider-scale political economies and shape the growth of great empires or states.
Around 3500 BC, regionally distinct herding economies were found across the Eurasian steppes. In some regions, these societies were the first to domesticate and ride horses. Over the next 2000 years, key innovations introduced by steppe nomads such as chariots, domesticated horses, and advanced bronze metallurgy spread across the mountains and deserts of Inner Asia and influenced the political and economic character of ancient civilizations from China to Mesopotamia, Iran, and the Indus Valley.
Although the mobile societies that fueled these networks came to share certain ideological and economic institutions, in many cases their political organization remained autonomous and idiosyncratic. Still, these regional economic and social ties forged between neighboring mobile communities helped new ideologies and institutions propagate over vast territories, millennia before the fabled "Silk Road."

Current Anthropology is a transnational journal devoted to research on humankind, encompassing the full range of anthropological scholarship on human cultures and on the human and other primate species. Communicating across the subfields, the journal features papers in a wide variety of areas, including social, cultural, and physical anthropology as well as ethnology and ethnohistory, archaeology and prehistory, folklore, and linguistics. It is published through a partnership between the Wenner-Gren Foundation for Anthropological Research and the University of Chicago Press.

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.
A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...
Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
