Researchers from North Carolina State University, Duke University and the University of Copenhagen have created the world’s largest DNA origami, which are nanoscale constructions with applications ranging from biomedical research to nanoelectronics.

“These origami can be customized for use in everything from studying cell behavior to creating templates for the nanofabrication of electronic components,” says Dr. Thom LaBean, an associate professor of materials science and engineering at NC State and senior author of a paper describing the work.

With their long, spiky legs and their propensity for eating anything, including each other, camel crickets are the stuff of nightmares. Research from North Carolina State University finds that non-native camel cricket species have spread into homes across the eastern United States.

“The good news is that camel crickets don’t bite or pose any kind of threat to humans,” says Dr. Mary Jane Epps, a postdoctoral researcher at NC State and lead author of a paper about the research. (more…)

Research Paves Way for Cyborg Moth ‘Biobots’

North Carolina State University researchers have developed methods for electronically manipulating the flight muscles of moths and for monitoring the electrical signals moths use to control those muscles. The work opens the door to the development of remotely controlled moths, or “biobots,” for use in emergency response. (more…)

Lack of Plant Diversity Spurs Cankerworm Damage in Cities

Research from North Carolina State University finds that a lack of plant diversity is a key contributor to the widespread defoliation caused by cankerworms in cities, and highlights the role that increasing diversity can play in limiting future damage.

Fall cankerworms (Alsophila pometaria) are caterpillars that are native to the eastern United States and hatch in early spring. The cankerworms defoliate trees and other plants, eating new leaves as they emerge – which is both unsightly and can ultimately kill the plants. (more…)

New Ultrasound Device May Aid in Detecting Risk for Heart Attack, Stroke

Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed an ultrasound device that could help identify arterial plaque that is at high risk of breaking off and causing heart attack or stroke.

At issue is the plaque that builds up in arteries as we age. Some types of plaque are deemed “vulnerable,” meaning that they are more likely to detach from the artery wall and cause heart attack or stroke. (more…)

Study: People Pay More Attention to the Upper Half of Field of Vision

A new study from North Carolina State University and the University of Toronto finds that people pay more attention to the upper half of their field of vision – a finding which could have ramifications for everything from traffic signs to software interface design.

“Specifically, we tested people’s ability to quickly identify a target amidst visual clutter,” says Dr. Jing Feng, an assistant professor of psychology at NC State and lead author of a paper on the work. “Basically, we wanted to see where people concentrate their attention at first glance.” (more…)

Researchers Grow Carbon Nanofibers Using Ambient Air, Without Toxic Ammonia

Researchers from North Carolina State University have demonstrated that vertically aligned carbon nanofibers (VACNFs) can be manufactured using ambient air, making the manufacturing process safer and less expensive. VACNFs hold promise for use in gene-delivery tools, sensors, batteries and other technologies.

Conventional techniques for creating VACNFs rely on the use of ammonia gas, which is toxic. And while ammonia gas is not expensive, it’s not free. (more…)

Researchers Describe Oxygen’s Different Shapes

Oxygen-16, one of the key elements of life on earth, is produced by a series of reactions inside of red giant stars. Now a team of physicists, including one from North Carolina State University, has revealed how the element’s nuclear shape changes depending on its state, even though other attributes such as spin and parity don’t appear to differ. Their findings may shed light on how oxygen is produced.

Carbon and oxygen are formed when helium burns inside of red giant stars. Carbon-12 forms when three helium-4 nuclei combine in a very specific way (called the triple alpha process), and oxygen-16 is the combination of a carbon-12 and another helium-4 nucleus. (more…)
