Is your inbox burning you out? Then take heart - research from the University of British Columbia suggests that easing up on email checking can help reduce psychological stress. Some of the study's 124 adults -- including students, financial analysts, medical ...

Research could improve nuclear power plant safety

December 4, 2014 4:30 pm | by EurekAlert! | Comments

Taking inspiration from nature, researchers have created a versatile model to predict how stalagmite-like structures form in nuclear processing plants - as well as how lime scale builds up in kettles. "It's a wonderful example of how complex mathematical ...

Achieving electron pairs on demand

December 4, 2014 4:25 pm | by EurekAlert! | Comments

In quantum optics, generating entangled and spatially separated photon pairs (e.g. for quantum cryptography) is already a reality. So far, it has, however, not been possible to demonstrate an analogous generation and spatial separation of entangled electron ...

December 4, 2014 4:19 pm | by EurekAlert! | Comments

A University of Texas at Dallas professor applied robot control theory to enable powered prosthetics to dynamically respond to the wearer's environment and help amputees walk. In research available online and in an upcoming print issue of ...

When noise gets electrons moving

December 4, 2014 4:16 pm | by EurekAlert! | Comments

Studying the motion of electrons in a disordered environment is no simple task. Often, understanding such effects requires a quantum simulator designed to expose them in a different physical setup. This was precisely the approach adopted by ...

EU companies must boost R&D to stay globally competitive

December 4, 2014 4:12 pm | by EurekAlert! | Comments

Investment in research and development by companies based in the EU grew by 2.6% in 2013, despite the unfavourable economic environment. However, this growth has slowed in comparison to the previous year's 6.8%. It is also below the 2013 world ...

Pulsars with black holes could hold the 'holy grail' of gravity

December 4, 2014 3:58 pm | by EurekAlert! | Comments

The intermittent light emitted by pulsars, the most precise timekeepers in the universe, allows scientists to verify Einstein's theory of relativity, especially when these objects are paired up with another neutron star or white dwarf that interferes with ...
