Four papers that expand upon the record on the origins of agriculture will appear in a supplement, guest edited by O. Bar-Yosef, Director of the Stone Age Lab at the Peabody Museum of Harvard University, to the August/November 2004 issue of Current Anthropology. Taken as a set, they demonstrate the maturation of the study of agricultural origins through fine-grained regional analyses and new methodological techniques.
Peter Rowley-Conwy in "How the West Was Lost: A Reconsideration of Agricultural Origins in Britain, Ireland, and Southern Scandinavia" shows that the data accumulated during the last 15 years in northwest Europe draws a different scenario from that commonly accepted at present. Rowley-Conwy asserts that rather than the gradual establishment of an agricultural subsistence economy in Ireland, Britain and southern Scandinavia, the process was a rapid "revolution," perhaps due to depletion of local resources or rapid environmental changes.
Natalie D. Munros paper, "Zooarchaeological Measures of Hunting Pressure and Occupation Intensity in the Natufian Implications for Agricultural Origins," presents plausible background for a sequence of events leading to intentional cultivation, by demonstrating the depletion of animal tissue resources during the Younger Dryas (13,000-11,600 cal BP) in the southern Levant.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
