A tiny light source and sensors at the end of an endoscope may provide a more accurate way to identify pre-cancerous cells in the lining of the esophagus. Developed by biomedical engineers at Duke University and successfully tested on patients during a clinical trial at the University of North Carolina at Chapel Hill, the device holds the promise of being a less invasive method for testing patients suspected of having Barrett's esophagus, a change in the lining of the esophagus due to acid...

A key focus of the health care debate has involved immigrants and their impact on the U.S. health care system. A new study shows that Mexican Americans most integrated into the culture -- including those born in the United States -- are more likely to require resources to manage their health conditions than more recent immigrants to the U.S., according to researchers at Duke University, Rice University and the University of Colorado Denver. "The implications of these findings run counter to...

Using lasers to contain some ultra-chilled atoms, a team of scientists has measured the viscosity or stickiness of a gas often considered to be the sixth state of matter. The measurements verify that this gas can be used as a "scale model" of exotic matter, such as super-high temperature superconductors, the nuclear matter of neutron stars, and even the state of matter created microseconds after the Big Bang. The results may also allow experimental tests of string theory in the future. Duke...

The brain's visual neurons continually develop predictions of what they will perceive and then correct erroneous assumptions as they take in additional external information, according to new research done at Duke University. This new mechanism for visual cognition challenges the currently held model of sight and could change the way neuroscientists study the brain. The new vision model is called predictive coding. It is more complex and adds an extra dimension to the standard model of sight....

What sets mankind's closest relatives "” monkeys, apes, and other primates "” apart from other animals? According to a new study, one answer is that primates are less susceptible to the seasonal ups and downs "” particularly rainfall"” that take their toll on other animals. The findings may also help explain the evolutionary success of early humans, scientists say. The study appeared online in the November 30 issue of American Naturalist. "Wild animals deal with a...

Long a staple of nature documentaries, the somewhat bizarre development of a grub-like pink marsupial embryo outside the mother's womb is curious in another way. Duke University researchers have found that the developmental program executed by the marsupial embryo runs in a different order than the program executed by virtually every other vertebrate animal. "The limbs are at a different place in the entire timeline," said Anna Keyte, a postdoctoral biology researcher at Duke who did this...

The ability to tell the difference between crystals that formed naturally and those formed by human activity can be important to archaeologists in the field. This can be a crucial bit of information in determining the ancient activities that took place at a site, yet archaeologists often wait for months for the results of laboratory tests. Now, however, an international team of physicists, archaeologists and materials scientists has developed a process that can tell in a matter of minutes the...

Leaks from carbon dioxide injected deep underground to help fight climate change could bubble up into drinking water aquifers near the surface, driving up levels of contaminants in the water tenfold or more in some places, according to a study by Duke University scientists. Based on a year-long analysis of core samples from four drinking water aquifers, "We found the potential for contamination is real, but there are ways to avoid or reduce the risk," says Robert B. Jackson, Nicholas...
