...etle, Titaneus giganteus . This study is a first step toward understanding what controls body size in insects. It's the legs that count in the beetles studied here, but what matters for the other hundreds of thousands of beetle species and millions of insect species overall is still an open question, sa...New, more direct pathways from outside the cell-to-cell nuclei discovered
...us." Therefore, his discovery means that "one less step is needed for extracellular material to get into the nucleus, and so it is far easier than previously thought for this material to get into the nucleus."

...occurring in human egg cell development. The first step in the development of an egg cell is the division of its progenitor cell, the oocyte. Unlike other cells in the body, an oocyte does not divide equally to produce two identical daughter cells.

In fact, the authors suggest that this second interaction either involves dissociation from syntaxin or a conformational change in the N-terminal domain of Munc18. 2.
