Dopamine deficiency is indicative of serious diseases of the nervous system. Tests of dopamine concentration are expensive and require specialised equipment that is unavailable in doctors' offices. New electrodes coated with carbon nanoparticles deposited on silicate submicroparticles allow to detect dopamine in solutions easily and at low cost, even in the presence of interferences.

If quantum computers are ever to be realized, they likely will be made of different types of parts that will need to share information with one another, just like the memory and logic circuits in today's computers do. However, prospects for achieving this kind of communication seemed distant - until now. A team of physicists has shown for the first time how these parts might communicate effectively.

New research by engineers at the Yale School of Engineering and Applied Science demonstrates that nanomechanical resonators can operate at much higher amplitudes than previously thought. The results represent an advance in optomechanics, in which the force of light is used to control mechanical devices. The findings could have implications for future communications and sensing technologies.
