Moving a step closer toward quantum computing, a research team in the Netherlands recently fabricated a photodetector based on a single nanowire, in which the active element is a single quantum dot with a volume of a mere 7,000 cubic nanometers. The device is described in the journal Applied Physics Letters.

Manufacturing semiconductors for electronics involves etching small features onto wafers using lasers, a process that is limited by the wavelength of the light itself. The development of a new, intense 13.5-nm light source will resolve this issue by reducing the feature size by an order of magnitude or so, according to Purdue researchers writing in the Journal of Applied Physics.

One of the rarest metals on Earth may be an excellent option for enabling future flash memory chips to continue increasing in speed and density, according to a group of researchers in Taiwan, who describe incorporating nanocrystals of iridium into critical components of flash memory in the journal Applied Physics Letters.

Over expressing a transcription factor that promotes increase in number of mitochondria greatly improves neurological function of transgenic mice models for Huntington's disease.

The first few days after birth is an important time when babies learn to recognize the sound of their parents' voice and the parents in turn bond with their children. However, the separation between parents and newborns admitted to the NICU can disrupt the early development of this relationship. The MUHC led an innovative research that suggests reading to newborns in the NICU allows parents to feel closer to their babies during this difficult period.

For patients with glioma, the most common primary brain tumor, new findings may explain why current therapies fail to eradicate the cancer. A UCSF-led team of scientists has identified for the first time that progenitor rather than neural stem cells underly a type of glioma called oligodendroglioma.

New study says post-9/11 "security zones" in major American cities blight landscape, create "architecture of fear" and safety effects may be negligible.

With the holidays fast approaching and consumers in full shopping mode, new research shows a single luxury item purchase can lead to an unintended shopping spree.

Managers in the private and public sectors must consider work environment when rationalizing production to obtain sustainable systems. A research study published in the journal Applied Ergonomics reveals that rationalization measures often have a major negative impact on both the physical and psychosocial work environment. "However, the review also presents scientific evidence on how to reduce this problem," says one of the researchers, at the University of Gothenburg.

Seeing bad things happen to other people is scary. One way to respond to this is to blame the victim -- to look for some reason why it happened to them. But there's another common response, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The researchers found that people who believe in justice in the world also believe that a tragedy gives the victim's life more meaning.

UC Irvine researchers have identified a novel mechanism in the brain that boosts memory.

Enormous uncertainty. These two words describe the condition of Phoenix's climate and water supply in the 21st century. Reservoirs have dipped to their lowest levels, continuous drought has plagued the state and forecasts for even warmer summers are predicted. Despite this uncertainty, professors at Arizona State University say there's no need to be fearful because positive impacts can be made.

Genetically modified cells can be made to communicate with each other as if they were electronic circuits. Using yeast cells, a group of researchers at the University of Gothenburg, Sweden, has taken a groundbreaking step towards being able to build complex systems in the future where the body's own cells help to keep us healthy. The study was presented recently in an article in the scientific journal Nature.

A novel project using cameras mounted on unmanned aircraft flying over the Arctic is serving double duty by assessing the characteristics of declining sea ice and using the same aerial photos to pinpoint seals that have hauled up on ice floes.

Living in an area where amenities of daily life -- groceries, playgrounds, post offices, libraries and restaurants -- are within walking distance is linked to higher levels of social capital, new research finds.
