Nanoscale plasmonic motor drives micro-sized disk

While those wonderful light sabers in the Star Wars films remain the figment of George Lucas' fertile imagination, light mills - rotary motors driven by light - that can power objects thousands of times greater in size are now fact. Researchers have created the first nano-sized light mill motor whose rotational speed and direction can be controlled by tuning the frequency of the incident light waves.

European Commission publishes reference report on definition of nanomaterials for regulatory purposes

Despite the growing utilisation of engineered nanomaterials in consumer products and innovative technological applications, there is at present no widely accepted definition of the term "nanomaterial" that is suitable as a basis for legislation on their safe use. Responding to a request of the European Parliament, the Joint Research Centre (JRC) published today a reference report entitled 'Considerations on a definition of nanomaterial for regulatory purposes".

Search for the bridge to the quantum world

Science fiction has nothing over quantum physics when it comes to presenting us with a labyrinthine world that can twist your mind into knots when you try to make sense of it. A team of Arizona State University researchers, however, believe they've opened a door to a clearer view of how the common, everyday world we experience through our senses emerges from the ethereal quantum world.
