Biological processes that govern our lives are many, intertwined, and often difficult to understand. They involve countless ...

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic ...

For life to evolve on Earth, a bunch of complex organic molecules had to evolve a way to assemble into cells. So how did ...

Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

Cancer cells have softer membranes than healthy cells. New nanoparticles exploit this physical difference to fuse selectively ...

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines ...

The plasma membrane is what isolates the cell’s interior from its surroundings. It is made up of a lipid bilayer and other macromolecules, such as carbohydrates, glycoproteins, and membrane proteins, ...

The upper size limit on cell-penetrating drug molecules may be much higher than medicinal chemists had thought. A research team reports that molecules believed to be much too large to diffuse across ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...
