of the great storehouse of material remaining from populations such as the ancient Egyptians. Many thousands of skeletons survive as well. The dividing line between mummy and skeleton is not sharp. Most mummies are poorly preserved, often consisting almost wholly of skeletal material inside the wrappings. Similarly, dry desert environments frequently preserve some soft tissue in addition to ske...

Hans Spemann (1869-1941)

Hans Spemann [5] was an experimental embryologist best known for his transplantation studies [6] and as the originator of the ?organizer? concept. One of his earliest experiments involved constricting the blastomeres of a fertilized salamander [7] egg [8] with a noose of fine baby hair, resulting in a partially double embryo with two heads and one tail. Spemann continued changing variables such...

This paper presents a tunable optofluidic prism based on the configuration of two laminar flow streams with different refractive indices in a triangular chamber. The chambers with 70 and 90 apex angles are designed based on simulation results, which provide the optimum working range and avoid recirculating flows in the chambers. In addition, a hydrodynamic model has been developed to predict th...

The transmembrane protein Crumbs (Crb) functions in apical polarity and epithelial integrity. To better understand its role in epithelial morphogenesis, we examined Crb localization and dynamics in the late follicular epithelium of Drosophila. Crb was unexpectedly dynamic during middle-to-late stages of egg chamber development, being lost from the marginal zone (MZ) in stage 9 before abruptly r...
