Lipids, or fats, are essential to life. They form the membranes around cells, protecting them from the outside. In nature, ...

“Understanding the structure of axons is important for understanding brain cell signaling,” says Shigeki Watanabe, Ph.D., ...

Cell structure Description Function Cell type Cell wall Freely permeable layer surrounding cell membrane. The cell wall of plant cells is made from cellulose. This gives them a rigid structure.

The electron microscope reveals the structure of this gossamer layer, which not only constitutes the exterior of the cell but also folds inward to make up much of its internal architecture ...

A new study challenges the long-held belief that axons, brain cell extensions, are tube-like, revealing instead a "pearl-on-a ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, ...

Biology textbooks may need a revision, say scientists, who present new evidence that an arm-like structure of mammalian brain cells may be a different shape than scientists have assumed for more than ...

GC-A's elongated structure and relatively thin anchoring in the cell membrane make it "floppy," with a shape that is difficult to capture. It usually has a different conformation in each cryo-EM ...
