Researchers at the Niels Bohr Institute have demonstrated that photons emitted from light sources embedded in a complex and disordered structure are able to mutually coordinate their paths through the medium.
Investigators at the Virginia Tech Carilion Research Institute have invented a way to directly image biological structures at their most fundamental level and in their natural habitats. The technique is a major advancement toward the ultimate goal of imaging biological processes in action at the atomic level.
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.
While some miRNAs impact onset and progression of cancer, others can actually suppress the development of malignant tumors and are useful in cancer therapy. They can also serve as potential biomarkers for early cancer detection.
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.
A research team has confirmed long-standing suspicions among physicists that electrons in a crystalline structure called a kagome (kah-go-may) lattice can form a "spin liquid," a novel quantum state of matter in which the electrons' magnetic orientation remains in a constant state of change.
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.
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.
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.
