Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response. Nearly 80 percent of the species aren’t yet shifting their geographic distributions to higher latitudes. Instead, they’re staying in place – but speeding up their life cycles. The Duke University-led study, published online Wednesday...

Surface Mining Environmental Cost
2013-09-12 10:02:17

Brett Smith for redOrbit.com - Your Universe Online To satiate the United States’ fierce appetite for coal, miners often utilize a tactic called surface mining, which involves stripping away rock and topsoil to access the fossil fuel below. According to a new report from researchers from Duke University just published in the journal PLOS ONE, coal retrieved from the Earth through surface mining comes at a significant cost to the ecosystem. Study researcher Brian D. Lutz, currently...

Electronic devices with touchscreens are ubiquitous, and one key piece of technology makes them possible: transparent conductors. However, the cost and the physical limitations of the material these conductors are usually made of are hampering progress toward flexible touchscreen devices. Fortunately, a research collaboration between the University of Pennsylvania and Duke University has shown a new a way to design transparent conductors using metal nanowires that could enable less...

Listing Calories Online May Help Consumers Make Healthier Decisions

Michael Harper for redOrbit.com - Your Universe Online A new study from Duke University claims restaurants would do well to include caloric listings along with their healthier offerings on their websites and apps. As the nation discusses healthcare reform, there are those who are quite concerned with what role the obesity epidemic will have on the conversation. According to the Duke University study, Americans can only make healthier choices if they’re aware of them. If customers...

Autism Risk Factors From Induced Or Augmented Labor
2013-08-13 06:32:41

redOrbit Staff & Wire Reports - Your Universe Online Pregnant women who have labor induced or augmented may have an increased risk of bearing children who are autistic, according to the findings of a large retrospective analysis appearing in the August 12 edition of the journal JAMA Pediatrics. Researchers from Duke Medicine and the University of Michigan reviewed North Carolina state birth and educational records. They performed an epidemiological analysis of over 625,000 live...

Microscopic tears in a new kind of man-made material may actually help the substance bulk up like a bodybuilder at the gym. "We've shown how normally destructive mechanical forces can be channeled to bring about stronger materials," said Duke chemist Steve Craig, who led the research. "The material responses are like Silly Putty transforming into a solid as stiff as the cap of a pen or a runny liquid transforming into soft Jell-O." Scientists could one day use the stress-induced...

Mandating outpatient treatment for certain people with severe mental illness, while controversial, results in substantial cost savings by cutting hospitalizations and increasing outpatient care, according to a financial analysis led by researchers at Duke Medicine. The finding – focusing on a program in New York termed Assisted Outpatient Commitment, or "Kendra's Law" - provides a key piece of information in the ongoing policy debate about appropriate treatment approaches...

Duke researchers have devised a way to quickly and easily target and tinker with any gene in the human genome. The new tool, which builds on an RNA-guided enzyme they borrowed from bacteria, is being made freely available to researchers who may now apply it to the next round of genome discovery. The new method also has obvious utility for gene therapy and for efforts to reprogram stem or adult cells into other cell types – for example, to make new neurons from skin cells....

What Peahens Want
2013-07-25 14:55:11

Brett Smith for redOrbit.com - Your Universe Online Finding out what women want is a question that science may never answer. However, a team of biologists from the University of California, Davis and Duke University has gained new insight into what a typical peahen may be looking for in her mate. Peacocks are renowned for their colorful trains, which are grown during the mating season and used to attract females. But what about the train catches a female eye? To see how these...

Climate Change Harp Seals Abandon Pups
2013-07-22 15:20:51

Lee Rannals for redOrbit.com - Your Universe Online Duke University scientists have determined that young harp seals off the eastern coast of Canada are at a greater risk of getting stranded than adult seals due to climate change. Researchers wrote in the open-access journal PLOS ONE that declining sea ice is leaving baby harp seals stranded in greater numbers. "Stranding rates for the region's adult seals have generally not gone up as sea ice cover has declined; it's the...
