Quantum-entangled light from a vibrating membrane

Entanglement, a powerful form of correlation among quantum systems, is an important resource for quantum computing. Researchers from the Quantum Optomechanics group at the Niels Bohr Institute, University of Copenhagen, recently ...

'Flapping wings' powered by the Sun

In ancient Greek mythology, Icarus' wax wings melted when he dared to fly too close to the sun. Now, researchers reporting in ACS Applied Materials & Interfaces have made artificial wings that are actually powered by the ...

Supercapacitors turbocharged by laxatives

An international team of scientists, including a professor of chemistry from the University of Bristol, has worked out a way to improve energy storage devices called supercapacitors, by designing a new class of detergents ...

Sheaths drive powerful new artificial muscles

Over the last 15 years, researchers at The University of Texas at Dallas and their international colleagues have invented several types of strong, powerful artificial muscles using materials ranging from high-tech carbon ...

Mechanical rice production

Growing rice is an intensive business. But in China where it is the primary food crop, mechanisation has not reached maturity, although it is as high as 90 per cent in some provinces. Writing in the International Journal ...
