The Dishevelled protein regulates many developmental processes in animals ranging from Hydra to humans. Here, we discuss the various known signaling activities of this enigmatic protein and focus on the biological processes that Dishevelled controls. Through its many signaling activities, Dishevelled plays important roles in the embryo and the adult, ranging from cell-fate specification and cel...

Expanded fluorescent protein techniques employing photo-switchable and fluorescent timer proteins have become important tools in biological research. These tools allow researchers to address a major challenge in cell and developmental biology, namely obtaining kinetic information about the processes that determine the distribution and abundance of proteins in cells and tissues. This knowledge i...

Phenotypes are the products of developmental processes whose dynamics are controlled by genes. In many developmental processes there is a nonlinear relationship between genetic variation and phenotypic variation. These nonlinear relationships can result in the emergence of dominance among alleles that control the developmental process. We explore the properties of dominance relationships in a s...

A recent workshop brought together a mix of researchers with expertise in optical physics, cerebral hemodynamics, cognitive neuroscience, and developmental psychology to review the potential utility of near-IR spectroscopy (NIRS) for studies of brain activity underlying cognitive processing in human infants. We summarize the key findings that emerged from this workshop and outline the pros and ...

homeobox (hox) genes are contributed in the genetic control of development of the body plan, pattern formation, and cell fate determination and the other several key developmental processes. hox genes are also known as selector genes because expression within a given section of the embryo will cause its cells to choose a particular developmental path. hox genes encode transcription factors that...

The technological component is now freely and intensively penetrating the format of modern journalism. New concepts methods have emerged. nature mass media has changed, a synthetic, multifunctional world systematically demonstrated in information space. Now journalistic community come close to perceiving social environment through lenses pluralistic scientific knowledge. It clear that new think...
