Arsenic (As) cycling in flooded rice paddies is driven by soil microbes which among other transformations can cause conversion between inorganic and organic As species. Silicon (Si)-rich amendments increased methylated species, particularly DMA, grain likely because they influence the microbial community responsible for methylation, but mechanism remains unclear. To investigate how Si-rich infl...

In the wooded landscapes on last northern slopes of mountain Cer, a very well-preserved palisade ditch enclosure small dimensions and regular circular shape was discovered (site Sancina, Desic village). Over few years, archaeological excavations at this site have focused inner space, bordered by massive ring-shaped earthen rampart. An unusually wide deep surrounds high embankment flattened coni...

Prostate cancer’s incidence, prevalence, etiology, and risk factors, and the influence of clinical trials on imaging technology development are discussed. One in seven Western men older than 70 will develop prostate cancer. The advent of prostate-specific antigen (PSA) screening means most men will now be diagnosed with early disease (85% not palpable on digital rectal exam (DRE), fewer grade 8...

This paper describes experiments in which the combustion of animal tissue (pork) was measured under a variety of conditions that may be encountered in fire scenes. Combustion depends on substantial preheating of the tissue by an external heat source and the availability of a porous wick (such as charred cellulosic material). Combustion of moderate-size samples can proceed at a moderate rate of ...

Our understanding of the evolution of domestication has changed radically in the past 10 years, from a relatively simplistic rapid origin scenario to a protracted complex process in which plants adapted to the human environment. The adaptation of plants continued as the human environment changed with the expansion of agriculture from its centres of origin. Using archaeogenomics and computationa...
