Lipid bilayers form the thin and floppy membranes that define the boundary of compartments such as cells. Now, a method to control the shape and size of bilayers using DNA nanoscaffolds has been ...

A new method for manipulating macromolecules has been developed by researchers. The technique uses double-stranded DNA to direct the behavior of other molecules. A new method for manipulating ...

The three-dimensional structure adopted by biological macromolecules largely determines their role in different cellular processes. Several different imaging techniques ranging from X-ray ...

Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The ...
