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 ...

Sticky spots on cell membranes hold onto the master regulator of cell polarity, helping to ensure that the regulatory protein accumulates in high enough concentrations to trigger cell polarity. Over ...

The American Biology Teacher, a nationally recognized journal, offers articles on recent advances in biology and life science, instructional activities for the classroom and laboratory, and ...

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 ...

ABSTRACT: The Goldman Hodgkin and Katz equation (GHK) is regarded as a cornerstone in the field of biology. The GHK equation expands upon Bernstein’s hypothesis. Bernstein had originally employed the ...

Neuroscientists at the University of Cambridge have identified five "major epochs" of brain structure over the course of a ...

Light and electron microscopes allow us to see inside cells. Plant, animal and bacterial cells have smaller components each with a specific function. Enzymes - Edexcel Enzymes are biological catalysts ...
