Shedding light on Anderson localization

Waves do not spread in a disordered medium if there is less than one wavelength between two defects. Physicists from the universities of Zurich and Constance have now proved Nobel Prize winner Philip W. Anderson's theory directly for the first time using the diffusion of light in a cloudy medium.

The secret of nanoparticle packing in cement

Cement production is responsible for 5% of carbon dioxide emissions. If we are to invent a "green" cement, we need to understand in more detail the legendary qualities of traditional Portland cement.

Photons emitted by quantum dots can be made indistinguishable through quantum frequency conversion

An international collaboration has demonstrated the ability to make photons emitted by quantum dots at different frequencies identical to each other by shifting their frequencies to match. This "quantum frequency conversion" is an important step for making solid-state, single photon sources, including quantum dots, more useful light sources for photonic quantum information science.

Super-fine sound beam could one day be an invisible scalpel

A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound approach say it could lead to an invisible knife for noninvasive surgery.

Preventing heat buildup within 3D integrated circuits

In the effort to pile more power atop silicon chips, engineers have developed the equivalent of mini-skyscrapers in three-dimensional integrated circuits and encountered a new challenge: how to manage the heat created within the tiny devices.

Pocket test measures 50 things in a drop of blood

A new device about the size of a business card could allow health care providers to test for insulin and other blood proteins, cholesterol, and even signs of viral or bacterial infection all at the same time - with one drop of blood.
