Scientists have identified the genes related to leaf angle in corn (maize) "“ a key trait for planting crops closer together, which has led to an eight-fold increase in yield since the early 1900s. (Nature Genetics, Jan. 9, 2011.) The study, led by researchers from Cornell and the U.S. Department of Agriculture "“ Agricultural Research Service (USDA-ARS) at Cornell and North Carolina State University, is the first to relate genetic variation across the entire maize genome to...

Researchers at North Carolina State University have created the first coils of silicon nanowire on a substrate that can be stretched to more than double their original length, moving us closer to incorporating stretchable electronic devices into clothing, implantable health-monitoring devices, and a host of other applications."In order to create stretchable electronics, you need to put electronics on a stretchable substrate, but electronic materials themselves tend to be rigid and fragile,"...

Matt Shipman, North Carolina State University The so-called "superstreet" traffic design results in significantly faster travel times, and leads to a drastic reduction in automobile collisions and injuries, according to North Carolina State University researchers who have conducted the largest-ever study of superstreets and their impacts. Superstreets are surface roads, not freeways.  It is defined as a thoroughfare where the left-hand turns from side streets are re-routed, as is traffic...

A new study from researchers at North Carolina State University sheds light on how a technique that is commonly used for making single-metal nanoparticles can be extended to create nanoparticles consisting of two metals "“ and that have tunable properties. The study also provides insight into the optical properties of some of these nanoparticles. Tuning the optical properties of nanoparticles is of interest for applications such as security technology, and for use in making chemical...

Researchers from North Carolina State University have developed a sensor that allows engineers to assess the scour potential of soils at various depths and on-site for the first time "“ a technology that will help evaluate the safety of civil infrastructure before and after storm events. Scour, or erosion of soil around structures due to water flow, is responsible for a wide range of critical infrastructure failures "“ from unstable bridges to the levees that gave way in the wake...

New research from North Carolina State University shows that most online news stories about cancer contain language that likely contributes to public uncertainty about the disease "“ a significant finding, given that at least one-third of Americans seek health information online. "Previous studies show that more than 100 million Americans seek health information online, and that their findings affect their health decisions," says Dr. Kami Kosenko, an assistant professor of communication...

By Mick Kulikowski, North Carolina State University In a finding that upends decades of scientific theory on reptile reproduction, researchers at North Carolina State University have discovered that female boa constrictors can squeeze out babies without mating. More strikingly, the finding shows that the babies produced from this asexual reproduction have attributes previously believed to be impossible. Large litters of all-female babies produced by the "super mom" boa constrictor show...

Republican claims of political corruption in North Carolina's Democratic Party have made little impact on public opinion among potential voters in the state, according to new polling data analyzed by North Carolina State University researchers. The findings show that highlighting actual corruption is not necessarily an effective electoral strategy. "The North Carolina Republican party has tried to brand state Democrats as corrupt, but we don't know whether voters respond to this strategy,"...

By Matt Shipman, North Carolina State University Researchers from North Carolina State University have found a way to optimize the development of DNA self-assembling materials, which hold promise for technologies ranging from drug delivery to molecular sensors. The key to the advance is the discovery of the "Goldilocks" length for DNA strands used in self-assembly "“ not too long, not too short, but just right. DNA strands contain genetic coding that will form bonds with another strand...

A new study from North Carolina State University finds that fish located near coal-fired power plants have lower levels of mercury than fish that live much further away. The surprising finding appears to be linked to high levels of another chemical, selenium, found near such facilities, which unfortunately poses problems of its own. "We found that fish in lakes located at least 30 kilometers (km) from a coal-fired power plant had mercury levels more than three times higher than fish of the...
