Cells are in constant competition with each other and so eliminate diseased or unwanted cells. Cell competition is therefore a central principle for maintaining the health of tissues and organs.

In response, a white blood cell arrives at the scene. This cell encircles the pathogen with its membrane, forming a tight, constricting ring. With remarkable force, the white blood cell yanks the ...

This is obviously far in excess of what a coin cell can put out instantaneously, but the key is in the surprising amount of potential energy stored in one of these batteries. If the cell is rated ...

This cell encircles the pathogen with its membrane, forming a tight, constricting ring. With remarkable force, the white blood cell yanks the pathogen off the wound’s surface. The white blood ...
