Previous crystal structures of membrane-spanning enzymes called ATPases have revealed that the enzymes undergo complex movements. The movements, it now emerges, involve rocking in place in the ...

Researchers have, for the first time, harnessed the molecular machinery of living systems to power an integrated circuit from ATP, the energy currency of life. They achieved this by integrating a ...

Ions move across cell membranes through either ion channels or ion pumps. Ions flow passively through ion channels, down electrical and concentration gradients, at speeds that can approach the ...

How a transport protein obtains its driving force from the energy storage molecule ATP, has been tracked dynamically. Using time-resolved infrared spectroscopy, they measured the structural changes in ...

Machines running on human energy? Yes, it can happen, according to Dan Nicolau, Jr. from the Department of Integrative Biology at the University of California. Nicolau and his colleagues successfully ...

Creating artificial cells is one of the great visions in both biology and engineering. Some of the ambitious visionaries radically rebuild cells that already exist in nature. Others – like the Max ...

Mitochondria are the powerhouses in our cells, producing the energy for all vital processes. Using cryo-electron tomography, researchers at the University of Basel, Switzerland, have now gained ...
