In a single day, a solitary grad student at a lab bench can produce more simple logic circuits than the world's entire output of silicon chips in a month. So says a Duke University engineer, who believes that the next generation of these logic circuits at the heart of computers will be produced inexpensively in almost limitless quantities. The secret is that instead of silicon chips serving as the platform for electric circuits, computer engineers will take advantage of the unique properties...

Children normally experience flights of fancy, including imaginary friends and conversations with stuffed animals, but some of them are also having hallucinations and delusions which might be the early signs of psychosis. A study of British 12-year-olds that asked whether they had ever seen things or heard voices that weren't really there, and then asked careful follow-up questions, has found that nearly 6 percent may be showing at least one definite symptom of psychosis. The children who...

DURHAM, N.C. -- A group of scientists who have studied the life history of primates for decades got to thinking about their own life histories and decided they had better do something to preserve their work for posterity. The conversation started after University of Wisconsin-Madison anthropologist Karen Strier experienced the unexpected deaths of two friends and academic colleagues "“ one a UW-Madison professor, the other a Brazilian graduate student. She approached Susan Alberts, a...

As airport security employees scan luggage for a large variety of banned items, they may miss a deadly box cutter if they find a water bottle first. According to new research at Duke University, identifying an easy-to-spot prohibited item such as a water bottle may hinder the discovery of other, harder-to-spot items in the same scan. Missing items in a complex visual search is not a new idea: in the medical field, it has been known since the 1960s that radiologists tend to miss a second...

New delivery platform may become a therapy for patients with vascular disease Scientists and engineers have used uniform magnetic fields to drive iron-bearing nanoparticles to metal stents in injured blood vessels, where the particles deliver a drug payload that successfully prevents blockages in those vessels. In this animal study, the novel technique achieved better results at a lower dose than conventional non-magnetic stent therapy. Conducted in cell cultures and rats, the research is the...

Energy-efficiency measures in the southern U.S. could save consumers $41 billion on their energy bills, open 380,000 new jobs, and save 8.6 billion gallons of water by 2020, according to a new study from the Nicholas Institute for Environmental Policy Solutions at Duke University and the Georgia Institute of Technology. The study concludes that investing $200 billion in energy efficiency programs by 2030 could return $448 billion in savings. The researchers modeled how implementation of nine...

A new study reconstructing thousands of years of fire history in the southern Appalachians supports the use of prescribed fire, or controlled burns, as a tool to reduce the risk of wildfires, restore and maintain forest health and protect rare ecological communities in the region's forests. Duke University researchers used radiocarbon analysis of 82 soil charcoal samples dating from 1977 to more than 4,000 years ago to reconstruct the fire history of a 25-acre site in the Nantahala National...

Duke University researchers have devised a method to dry and preserve proteins in a glassified form that seems to retain the molecules' properties as workhorses of biology. They are exploring whether their glassification technique could bring about protein-based drugs that are cheaper to make and easier to deliver than current techniques which render proteins into freeze dried powders to preserve them. Duke engineer and chemist David Needham describes this glassification process as "molecular...
