Increased productivity, not less energy use, results from more efficient lighting
More light, rather than lower costs, should be the result of increased efficiencies of LED lighting. But productivity will increase.

Quantum physics: New insights into the remote control of quantum systems
An international collaboration led by physicists of the University of Vienna shines new light on the question of the resources required for achieving quantum information processing. The scientists demonstrate that less demanding resources, which are easier to prepare and to control, can be used for quantum-enhanced technologies. In the experiment, which is published in Nature Physics, the researchers achieve remote quantum state preparation without requiring entanglement as a resource.

Reluctant electrons enable 'extraordinarily strong' negative refraction
Researchers at the Harvard School of Engineering and Applied Sciences have demonstrated a drastically new way of achieving negative refraction in a metamaterial. The advance, reported in the Aug. 2 issue of Nature, results in an "extraordinarily strong" negative refractive index as large as -700, more than a hundred times larger than most previously reported.

A giant step in a miniature world: UZH researcher measures the electrical charge of nano particles
Nano particles are a millionth of a millimeter in size, making them invisible to the human eye. Unless, that is, they are under the microscope of Prof. Madhavi Krishnan, a biophysicist at the University of Zurich. Prof. Krishnan has developed a new method that measures not only the size of the particles but also their electrostatic charge. Up until now it has not been possible to determine the charge of the particles directly.

Breakthrough by U of T-led research team leads to record efficiency for next-generation solar cells
Researchers from the University of Toronto (U of T) and King Abdullah University of Science & Technology (KAUST) have made a breakthrough in the development of colloidal quantum dot (CQD) films, leading to the most efficient CQD solar cell ever. Their work is featured in a letter published in Nature Nanotechnology. The researchers, led by U of T Engineering Professor Ted Sargent, created a solar cell out of inexpensive materials that was certified at a world-record 7.0 percent efficiency.
