UD-led breakthrough may advance development of mid-infrared light sources, lasers
A research group at the University of Delaware has achieved a breakthrough in the emerging field of “Group IV Semiconductor Optoelectronic Devices.”
The UD research team, led by James Kolodzey, demonstrated that it is possible to use a combination of germanium and tin (GeSn) to create a light emitting diode (LED) that operates in the infrared spectrum, wavelengths invisible to the naked eye. (more…)
UD professor, scholar document culture of Peruvian community
As the elders of a small hunter-gatherer community told the story of how their people came to be, University of Delaware assistant professor of art Jonathan Cox and Summer Scholar Sarah Driver sat and listened, intrigued by the tale.
Over the course of seven days, they learned firsthand about the Ese’eja (ess-a-eha) Nation, a community of three distinct villages living in the remote areas of Infierno, Palma Real and Sonene, Peru. (more…)
UD alumna Windle sets off on professional journey with feed company
After a decade at the University of Delaware, Michelle Windle is beginning her professional career with Vita Plus, a premier agricultural feed company located in Madison, Wis. And to think that it all began with her knocking on the doors of professors in the Department of Animal and Food Sciences during her junior year as an undergraduate looking for a job.
As fate would have it, Windle ended up knocking on the door of Limin Kung Jr., the S. Hallock du Pont Professor of Animal and Food Sciences, and he offered her some hours in his laboratory. “To tell you the truth, at the time I had bright red dreadlocks. I don’t know what he saw in me, but I’m glad that he did,” said Windle. (more…)
Oceanography graduate student lands scholarship supporting wetland research
Growing up along Lake Pontchartrain in New Orleans, Brandon Boyd spent a lot of time hunting for waterfowl and fishing for speckled trout in marshes and swamps. There, wetlands are a way of life.
US Cyber Challenge puts UD student on fast track to outwitting hackers
“Cryptography enables you to send secret code and hide information within a network to keep it secure,” Billy Bednar, a University of Delaware senior, told U.S. Sen. Tom Carper during a conference call Wednesday, July 18.
Carper, who is chairman of the Senate Homeland Security and Governmental Affairs Committee, is working to help safeguard the nation’s cyber space. To accomplish this he will need to rely on today’s leading experts, but also ensure that future cyber sleuths currently in the pipeline have the proper training to meet emerging cyber challenges.

The deep biosphere—the realm of sediments far below the seafloor—harbors a vast ecosystem of bacteria, archaea, and fungi that are actively metabolizing, proliferating, and moving, according a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and the University of Delaware (UD).
“This is the first molecular evidence for active cell division in the deep biosphere,” says WHOI postdoctoral investigator Bill Orsi, who was the lead author on the study. Previous studies and models had suggested cells were alive, but whether the cells were actually dividing or not had remained elusive. (more…)
NASA telescope provides insights into unusual dwarf star
Astronomer John Gizis of the University of Delaware, working with data obtained by NASA’s Kepler telescope, is studying a highly unusual dwarf star and its powerful flares that may hold clues to the likelihood of life on other planets as well as to the behavior of our sun.
Gizis, associate professor in the Department of Physics and Astronomy, discovered the star two years ago using a ground-based telescope and now has conducted additional research using Kepler observations over the past two years. (more…)
Active microbes discovered far beneath seafloor in ancient ocean sediment
Microbes are living more than 500 feet beneath the seafloor in 5 million-year-old sediment, according to new findings by researchers at the University of Delaware and Woods Hole Oceanographic Institution (WHOI).
Genetic material in mud from the bottom of the ocean — called the deep biosphere —revealed an ecosystem of active bacteria, fungi and other microscopic organisms at depths deeper than a skyscraper is high. The findings were published in Nature on June 12. (more…)
