Biomedical engineers have developed a silk-based, ultrathin membrane that can be used in organ-on-a-chip models to better mimic the natural environment of cells and tissues within the body. When used ...

Cells do more than carry out chemical reactions. New theoretical work suggests they may also generate usable electrical energy through constant motion in their membranes, offering a fresh way to think ...

Cells have always hummed with activity. They make their own energy, package it into molecules like ATP, and spend it ...
