After demonstrating that light accurately detected pre-cancerous cells in the lining of the esophagus, Duke University bioengineers turned their technology to the colon and have achieved similar results in a series of preliminary experiments. This technology could be a non-invasive way for physicians to detect abnormal cells, or dysplasia, which have the potential of turning cancerous. These cells are in the epithelium, or lining, of various tissues, including the esophagus and colon....

Removal Of Restrictions Can Decrease Music Piracy
2011-10-08 05:24:32

New research from Rice and Duke challenges conventional wisdom that removal of restrictions would increase piracy levels Contrary to the traditional views of the music industry, removal of digital rights management (DRM) restrictions can actually decrease piracy, according to new research from Rice University and Duke University. Marketing professors Dinah Vernik of Rice and Devavrat Purohit and Preyas Desai of Duke used analytical modeling to examine how piracy is influenced by the...

In a first ever demonstration of a two-way interaction between a primate brain and a virtual body, two monkeys trained at the Duke University Center for Neuroengineering learned to employ brain activity alone to move an avatar hand and identify the texture of virtual objects. "Someday in the near future, quadriplegic patients will take advantage of this technology not only to move their arms and hands and to walk again, but also to sense the texture of objects placed in their hands, or...

Research gives insight into 50-year-old mystery -- zinc important for learning and memory Zinc plays a critical role in regulating how neurons communicate with one another, and could affect how memories form and how we learn. The new research, in the current issue of Neuron, was authored by Xiao-an Zhang, now a chemistry professor at the University of Toronto Scarborough (UTSC), and colleagues at MIT and Duke University. Researchers have been trying to pin down the role of zinc in the...

Copper nanowires may be coming to a little screen near you. These new nanostructures have the potential to drive down the costs of displaying information on cell phones, e-readers and iPads, and they could also help engineers build foldable electronics and improved solar cells, according to new research. Duke chemist Ben Wiley and his graduate student have developed a technique to organize copper atoms in water to form long, thin, non-clumped nanowires. The nanowires are then...

Accidental Sea Turtle Deaths Down, But Still Too High
2011-09-15 04:48:28

  Some 4,600 sea turtles are accidentally caught and killed in U.S. fisheries every year, a 94 percent reduction since 1990, according to a new study published this month in the journal Biological Conservation. However, the progress may not be enough to sustain turtle populations, according to researchers at Duke University's Project Global and Conservation International, who conducted the study. The use of turtle-excluder devices (TEDs), or large holes that allow the sea...


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
