Sporulation may have given rise to the bacterial outer membrane: study
(PhysOrg.com) -- Bacteria can generally be divided into two classes: those with just one membrane and those with two. Now researchers at the California Institute of Technology (Caltech) have used a powerful ...

A surprising molecular switch: Lipids help control the development of cell polarity
In a standard biology textbook, cells tend to look more or less the same from all sides. But in real life cells have fronts and backs, tops and bottoms, and they orient many of their structures according to ...

Multi-compartment globular structures assembled from polymer-based materials may soon serve as cell prototypes
The cell is a host of many complex reaction pathways. These pathways usually do not interfere with each other because they are contained within membrane-bound compartments, known as organelles. The lipid membrane is extremely ...
