The history of developmental biology is interwoven with debates as to whether mechanistic explanations of development are possible or whether alternative explanatory principles or even vital forces need to be assumed. In particular, the demonstrated ability of embryonic cells to tune their developmental fate precisely to their relative position and the overall size of the embryo was once though…
In late April 2004, photographs taken in the Iraqi Abu Ghraib prison and electronically shared among American troops were leaked, causing outrage around the world. The images showed American military personnel torturing, humiliating, and sexu-ally abusing Iraqi detainees, in some cases to the point of mur-der, in flagrant violation of the Geneva Conventions. Among all the photographs, …
During the first half of the nineteenth century, some fundamental insights into pollen morphology and physiology were achieved. Purkinje made the first attempt for a palynological terminology by classifying pollen based on their morphology (Purkinje 1830). Wodehouse (1935) pointed out that “Purkinje’s system of nomenclature deserved much more attention than was ever given …
In principle, high-precision imaging of human vascular structures, including thoseinside the human hand, is a solved problem. Figure1.1a displays correspondingvessels using a Magnetic Resonance Angiography (MRA) medical imaging device,while Fig.1.1b shows the result of applying hyperspectral imaging using a STEM-MER IMAGING device using their Perception Studio software to visualise the datacapt…
d more in the development of science, particularly in Ethiopia, because the Italian language in which they are published is not more widely read. These results should be more widely known, and the present authors hope that this publication will help to remedy that problem. We provide commented translations of the papers that present the field observations and we analyse the update…
any people associate Building with Nature with its flagship project, the Sand Motor. This mega-nourishment redefined the role of natural processes in civil engineering projects, demonstrating that instead of ‘do no harm’ as the highest possible supporting goal of coastal infrastructure, the design could incorporate natural processes to attain societal and ecological goals. As such, the Sand…
