Researchers reveal structure and function of a molecular motor

Molecular motors are complex devices composed of many different parts that consume energy to perform various cellular activities. In short, molecular machines transform energy into useful work. Understanding the mechanistical ...

All wound up: A reversible molecular whirligig

Over the last few decades, researchers have built minuscule molecular machines that rotate or shuttle other molecules. However, it's difficult to determine the mechanical work and forces that these tiny contraptions produce, ...

How monitoring a quantum Otto engine affects its performance

Heat engines are devices that use waste heat to perform mechanical work and generate power. The invention of heat engines ushered in an era of the industrial revolution 250 years ago. The Otto engine, which uses distinct ...

Protocells spring into action

A University of Bristol-led team of international scientists with an interest in protoliving technologies, has today published research which paves the way to building new semi-autonomous devices with potential applications ...

Researchers create powerful unipolar carbon nanotube muscles

For more than 15 years, researchers at The University of Texas at Dallas and their collaborators in the U.S., Australia, South Korea and China have fabricated artificial muscles by twisting and coiling carbon nanotube or ...

Researchers create morphing crystals powered by water evaporation

Water evaporation, as observed when a puddle of water disappears on a summer day, is a remarkably powerful process. If it were harnessed, the process could provide a clean source of energy to power mechanical machines and ...
