UD professor works to overcome challenges in harnessing power of multicore computer processors

Computer processors that can complete multiple tasks simultaneously have been available in the mainstream for almost a decade. In fact, almost all processors developed today are multicore processors. Yet, computer programmers still struggle to efficiently harness their power because it is difficult to write correct and efficient parallel code.

According to the University of Delaware’s John Cavazos, to effectively exploit the power of multi-core processors, programs must be structured as a collection of independent tasks where separate tasks are executed on independent cores.

The complexity of modern software, however, makes this difficult. (more…)

Jan. 8-22: ‘The Abolitionists’

UD’s Armstrong Dunbar a featured expert in PBS series ‘The Abolitionists’

The Abolitionists, airing on PBS this month, is timed to coincide with the 150th anniversary of the Emancipation Proclamation, but it offers viewers “a real understanding of the complexities of what it took to end slavery” beyond Lincoln’s proclamation itself, a University of Delaware historian featured in the series says.

Erica Armstrong Dunbar, associate professor of history with joint appointments in Black American Studies and in women and gender studies, was approached by creators of the three-part series to provide her perspective on the issues and individuals featured. The Abolitionists is part of the “American Experience” series and is scheduled to air Tuesday nights, Jan. 8, 15 and 22. (more…)

Wind, solar power paired with storage could be cost-effective way to power grid

Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today’s electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.

A well-designed combination of wind power, solar power and storage in batteries and fuel cells would nearly always exceed electricity demands while keeping costs low, the scientists found. (more…)

UD sociologist writes book about ‘betrayal’ of African American veterans

For the University of Delaware’s Benjamin Fleury-Steiner, research for his new book Disposable Heroes: The Betrayal of African American Veterans was uncomfortable and disquieting.

An associate professor of sociology, Fleury-Steiner spent months interviewing black veterans of Vietnam, Iraq and Afghanistan in the back streets of Wilmington, Del., to learn more about their service to their country and their experiences upon returning home.

The topic had long been on Fleury-Steiner’s mind, himself an Army veteran of Operation Desert Storm who had ducked Scud missiles in Saudi Arabia. (more…)

Nanotechnology for drug delivery shows promise in treatment of pediatric leukemia

Nanotechnology developed by Delaware scientists could potentially deliver chemotherapy to children in a way that attacks cancer cells without harming healthy cells, greatly reducing side effects.

The work, conducted by researchers in the University of Delaware’s Department of Materials Science and Engineering and Nemours Center for Childhood Cancer Research, was published this month in the journal Molecular Pharmaceutics. (more…)

Delaware Geological Survey discovers evidence of past earthquakes

Delaware Geological Survey (DGS) scientists have uncovered hard proof of faults in northern Delaware, indicating the occurrence of earthquakes millions of years ago.

The geologic evidence turned up in sediment samples removed during a well-drilling project this summer from depths ranging 137 to 251 feet down in Smyrna and the Woodland Beach Wildlife Area.

“People have postulated that there are faults in this area,” DGS Senior Scientist Scott Andres said. “Now we have evidence of it.” (more…)

UD researchers show how beneficial soil bacteria can boost plant immunity

With the help of beneficial bacteria, plants can slam the door when disease pathogens come knocking, University of Delaware researchers have discovered.

A scientific team under the leadership of Harsh Bais, assistant professor of plant and soil sciences in UD’s College of Agriculture and Natural Resources, found that when pathogens attempt to invade a plant through the tiny open pores in its leaves, a surprising ally comes to the rescue. Soil bacteria at the plant’s roots signal the leaf pores to close, thwarting infection. (more…)

Scientists studying ocean currents and oil spills with large-scale experiment

Scientists are releasing hundreds of floating GPS devices into the Gulf of Mexico this week near the Deepwater Horizon site to study the role of ocean currents in oil spills. The experiment is the largest in scale of its kind, deploying 300 satellite-tracked, untethered buoys, called drifters, over the course of two and a half weeks.

“We’re trying to use the drifters as a simulation of an oil spill,” said Dennis Kirwan, Mary A.S. Lighthipe Professor of Marine Studies in the University of Delaware’s College of Earth, Ocean, and Environment. “This is a big event in oceanography.” (more…)
