First intensive investigation of early agriculture in Liangchengzhen suggests rice was prevalent


Archaeologists from the University of Toronto, the Field Museum, and Shandong University announce the results of the first intensive investigation of early agriculture in Liangchengzhen, Shandong in Northern China. The results are published in the April 2005 issue of Current Anthropology. Several thousand crop and weed seeds were recovered by the team at the 4000 year-old Liangchengzhen site, a regional political center in Shandong.

Prior to the investigation, Longshan agriculture was thought to have been millet-based, with rice having little importance. However, nearly half the grains collected in the study were from rice while the remainder was from fox-tail millet. According to radiocarbon dating, the grains removed from the pit date to 2000 B.C.

Modern grain agriculture in China is a successful combination of local rice and Near Eastern wheat. Several wheat grains were found at the site, indicating that the crop had come across Asia to eastern China prior to any other evidence of western contact in that region. The Liangchengzhen research shows that the rice-wheat complex developed even before the emergence of writing.

"Not only does rice appear to have been more significant for eastern Longshan people than previously suspected but the presence of wheat foreshadows more modern agriculture based on both rice and wheat. Wheat is rare at Liangchengzhen and was likely just being introduced to the region," the researchers contend.

A significant study of this kind has been needed. "Understanding of Late Neolithic food production in China has been hampered by a lack of palaeoethnobotanical research, "attest the scholars. "Setting such studies in an interdisciplinary framework is essential if we are to understand not only Late Neolithic agriculture but the origins of food production in China as well."

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
