Researchers have identified the set of tools an infectious microbe uses to persuade a plant to open the windows and let the bug and all of its friends inside. The microbe is Pseudomonas syringae, a successful bacterial pathogen that produces characteristic brown spots in more than 50 different species of plant. The signal it uses is a molecule called coronatine, which to the plant looks just like its own jasmonic acid, a signal that is part of the plant's immune system. The pathogen...

No matter how much time you've spent training your brain to multitask by playing "Call of Duty," you're probably no better at talking on the phone while driving than anybody else. A study by the Visual Cognition Laboratory at Duke University wanted to see whether gamers who have spent hours in front of a screen simultaneously watching the map, scanning doorways for bad guys and listening to the chatter of their fellow gamers could answer questions and drive at the same time. The finding:...

Experimental drug and genetic difference both indicate how people deal with fear and stress Researchers at Duke University and the National Institutes of Health have found a way to calm the fears of anxious mice with a drug that alters their brain chemistry. They've also found that human genetic differences related to the same brain chemistry influence how well people cope with fear and stress. It's an advance in understanding the brain's fear circuitry that the research team says may...

Treating adolescents for major depression can also reduce their chances of abusing drugs later on, a secondary benefit found in a five-year study of nearly 200 youths at 11 sites across the United States. Only 10 percent of 192 adolescents whose depression receded after 12 weeks of treatment later abused drugs, compared to 25 percent of those for whom treatment did not work, according to research led by John Curry, a professor of psychology and neuroscience at Duke University. "It...

While the Statue of Liberty and old pennies may continue to turn green, printed electronics and media screens made of copper nanowires will always keep their original color. Duke University chemists created a new set of flexible, electrically conductive nanowires from thin strands of copper atoms mixed with nickel. The copper-nickel nanowires, in the form of a film, conduct electricity even under conditions that break down the transfer of electrons in plain silver and copper nanowires, a...

A Duke University-led study of North Carolina toddlers suggests that exposure to potentially toxic flame-retardant chemicals may be higher in nonwhite toddlers than in white toddlers. The study also suggests that exposure to the chemicals is higher among toddlers whose fathers do not have a college degree, a proxy measure of lower socioeconomic background. Hand-to-mouth activity may account for a significant amount of the children's exposure to the contaminants, according to the study,...

A team of Duke University engineers plan to send us even further into the future as they have compiled a “master ingredient list” to create the next generation of quantum electronics. The teams list includes more than 2,000 compounds in this master list and hopes to drive the study of quantum physics even further. At the center of their studies are topological insulators (TI). These man made crystals serve multiple purposes as they are able to generate electricity on their...

Scientists at Duke University Medical Center have shown the ability to turn scar tissue that forms after a heart attack into heart muscle cells using a new process that eliminates the need for stem cell transplant. The study, published online April 26 in the journal Circulation Research, used molecules called microRNAs to trigger the cardiac tissue conversion in a lab dish and, for the first time, in a living mouse, demonstrating the potential of a simpler process for tissue regeneration....

Increased intake of dietary calcium may be key to addressing widespread dental health problems faced by millions of rural residents in Ethiopia's remote, poverty-stricken Main Rift Valley, according to a new Duke University-led study. As many as 8 million people living in the valley are estimated to be at risk of dental and skeletal fluorosis as a result of their long-term exposure to high levels of naturally occurring fluoride in the region's groundwater. Fluoride is essential for...
