Microscopic water droplets jumping from one surface to another may hold the key to a wide array of more energy efficient products, ranging from large solar panels to compact laptop computers. Duke University engineers have developed a new way of producing thermal diodes to regulate heat by bleeding it away or keeping it in. The method solves several shortcomings of existing devices. While thermal diodes can be made from solid materials, these solid-state diodes are not nearly as...

An attentive, nurturing mother may be able to help her children better resist the temptations of drug use later in life, according to a study in rats conducted by Duke University and the University of Adelaide in Australia. A rat mother's attention in early childhood actually changes the immune response in the brains of her pups by permanently altering genetic activity, according to Staci Bilbo, an assistant professor of psychology and neuroscience at Duke, who led the research. High-touch...

Clean energy can help meet growing electricity demand and minimize pollution in the Southern United States, but progress to adopt renewable energy strategies has been hindered by a number of myths, according to a new study by Duke and Georgia Tech researchers. These myths, encompassing both sides of the clean energy debate, may affect how the South responds to what is expected to be a 28 percent rise in population within the next 20 years. A study by researchers at Duke University and...

Young girls have been viewed as far more savvy than boys at navigating the emotional pitfalls of friendships. But a new report shows that when friends let them down, girls are even more devastated than boys, researchers from Boston College and Duke University report in the journal Child Development. Researchers examined whether or not girls cope better than boys when a friend violates a core expectation of friendships. The study of fourth- and fifth-grade children found that these...

Girls may be sugar and spice, but "everything nice" takes a back seat when friends let them down. In a Duke University study out Tuesday, researchers found that pre-teen girls may not be any better at friendships than boys, despite previous research suggesting otherwise. The findings suggest that when more serious violations of a friendship occur, girls struggle just as much and, in some ways, even more than boys. The girls in this study were just as likely as boys to report that they...

A new report by Duke University researchers offers several health and environmental measures for North Carolina lawmakers to consider as they debate legalizing horizontal drilling and hydraulic fracturing for natural gas. The study, which has been accepted for publication in the Duke Environmental Law and Policy Forum journal, looks at potential environmental hazards and how lawmakers in other states are factoring health and environmental risks into regulatory approaches targeting the...

In a finding that confirms what many obstetricians and gynecologists suspected, Duke University researchers report that younger women who undergo hysterectomies face a nearly two-fold increased risk for developing menopause early. The study, published in the December issue of the journal Obstetrics & Gynecology, is the largest analysis to track over time the actual hormonal impact of woman who had hysterectomies and compare them to women whose uteruses remained intact. "Hysterectomy...

The first predators that the cephalopods must be wary of are...
