Tightening Cloud Computing Security

Imagine sharing a backyard with your neighbor. Security concerns would abound, from unwanted visitors to missing tools and unruly pets. Sheng Wei, assistant professor of computer science and engineering, said the perils of a shared backyard illustrate potential security challenges of a high-speed computing platform: the CPU-FPGA hybrid, an architecture that boosts cloud computing’s speed. […]


Easing People’s Discomfort with Drones

Drone sightings are becoming more common, but many people are still apprehensive being around them. Nebraska computer scientist Brittany Duncan aims to ease discomfort by enabling drones to communicate their intentions, such as taking photos, and maintain comfortable distances. Communication also could make drones valuable coworkers. Duncan, assistant professor of computer science and engineering, earned […]


Engineering Flawless 3D Printing

Nebraska engineer Prahalada Rao envisions 3D printing no less than revolutionizing the world. But first the process must overcome a tendency to create flaws. “People call it ‘print and go.’ I call it ‘print and pray,’” said Rao, assistant professor of mechanical and materials engineering. To produce flawless items every time, Rao is improving the […]


Controlling Elasticity with Magnetism

Insights into a thermodynamic duo could inform engineering decisions and improve the functionality of designs featuring elastic components. Nebraska physicist Christian Binek found that, under certain conditions, the magnetism of certain materials can predict the relationship between their temperature and elasticity. His finding could allow engineers to control the elasticity of those materials by strategically […]


Cranking Up Fuel Cell Efficiency

Cars powered by hydrogen-based fuel cells have been environmentally friendly options for several years in California. But their hefty price tags are far less friendly, curtailing widespread adoption. Nebraska engineer Shudipto Dishari aims to both reduce fuel cell costs and improve energy efficiency. She earned a five-year, nearly $600,000 Faculty Early Career Development Program award […]


Aging Brains Look on Bright Side

Even as your knees get creakier and your hair grays, chances are you’re putting an increasingly positive spin on life. Nebraska’s Maital Neta, assistant professor of psychology, aims to understand why people interpret ambiguous everyday events (are they whispering about me?) more favorably as they age. Her research could one day help inform treatment options […]


Resilience Training Tackles Food, Water, Energy Issues

• 409 parts per million of carbon dioxide in the atmosphere. • 18.7 million acres deforested annually. These and other numbers hang above Daniel Rico’s laboratory desk – daily reminders of the urgent resilience and climate change problems he aims to tackle in his career. With support from a new National Science Foundation-funded interdisciplinary graduate […]


Workshops Focus on Arctic Changes

Participants devised strategies for managing rapid […]


Protecting Crops in a Warmer World

Higher temperatures caused by climate change aren’t just increasing the number of daytime scorchers. Nights are getting warmer as well, stressing plants and decreasing yields of vital crops worldwide. Nebraska plant pathologist Harkamal Walia aims to make wheat and rice, two major cereal crops, more resilient to the stress from higher nighttime temperatures. He and […]


Genetic Strategies Help Species Thrive Where They Live

As climate change leads to warmer winters, earlier springs and later autumns, many plants and animals are becoming out of sync with their environment. Some species may adapt, but will they adjust in time? The answer lies, in part, with the connection between information encoded in a species’ genes and the traits they evolved to […]
