All cells have an outer plasma membrane that regulates not only what ... to align side-by-side to form broad sheets (Figure 1). Glycerophospholipids are by far the most abundant lipids in cell ...

The fatty membrane surrounding every living cell is a vibrant environment where countless biological processes take place.

This is important because most signaling molecules are either too big or too charged to cross a cell's plasma membrane (Figure 1). Not all receptors exist on the exterior of the cell. Some exist ...

Light and electron microscopy have distinct limitations. Light microscopy makes it difficult to resolve smaller and smaller ...

A new study shows how an anticancer drug triggers an 'outside in' signal that gets it sucked into a cancer cell. The work reveals a new signaling mechanism that could be exploited for delivering other ...

A schematic of a polymer electrolyte membrane hydrogen-oxygen fuel cell is shown in Figure 1. Figure 1. Hydrogen-oxygen PEM fuel cell. Hydrogen molecules dissociatively adsorb at the anode and are ...
