Understanding how morphogens promote three-dimensional patterning is an important issue in developmental biology. Recently, new insights have been gained into the mechanisms by which the Drosophila ...

This paper seeks to identify the factors which have the greatest effect on gas diffusion rates into animal burrows, and in turn on the maximum size of burrowing animals which may rely on simple burrow ...

Some components necessary for the eventual construction of a general model relating the concentration and diffusion of oxygen to the ecology of soil organisms are elaborated from biochemical and ...

Cell membranes are thin measuring around 5 nanometers thick and to put that into perspective you could fit about 10,000 membranes across one human hair. However, does understanding a cell membrane's ...
