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 ...

Tabletop quantum experiment could detect gravitational waves

Predicted by Einstein's general theory of relativity, gravitational waves are ripples in space-time generated by certain movements of massive objects. They are important to study because they allow us to detect events in ...

Gold nanoparticles to save neurons from cell death

In a recent experiment, researchers have developed gold nanoparticles in the laboratory in order to reduce the cell death of neurons exposed to overexcitement. The study is the result of an international collaboration coordinated ...

The cascade to criticality

Combined theoretical and experimental work has resulted in a novel mechanism through which criticality emerges in quasiperiodic structures—a finding that provides unique insight into the physics on the middle ground between ...
