Researchers measure heat flow: from active metabolic forces inside cell to flickering cell membrane
Entropy is often associated with disorder and chaos, but in biology it is related to energy efficiency and is closely linked to metabolism, the set of chemical reactions that sustain life. This research was led by the Universities of Barcelona and Padua, with the participation of Göttingen University and the Universities Complutense and Francisco de Vitoria in Madrid. This international research team has developed a novel methodology for the measurement of entropy production at the scale of a nanometer, meaning one-billionth of a meter. The new approach enabled the scientists to measure the heat flow, known as the entropy production rate, of single red blood cells. ...
