The cell membrane is one of the most important components of a cell because it separates the interior from the environment and controls the movement of substances in and out of the cell. In a move that brings mankind another step closer to being able to create artificial life forms from scratch, chemists from the University of California, San Diego (UCSD), and Harvard University have created artificial self-assembling cell membranes using a novel chemical reaction. The chemists hope their creation will help shed light on the origins of life.
As the basic structural and functional unit of all known living organisms, the cell is the smallest unit of life that is classified as a living thing. Although there are various theories – meteorites, deep-sea vents, lightning – there is still no scientific consensus regarding the origin of the first cell.
