The increased levels of carbon dioxide in the atmosphere predicted for later this century may reduce the damage that future ice storms will cause to commercially important loblolly pine trees, according to a new study. |

A new study has disclosed perhaps the strongest evidence to date for superfluidity in an exotic gas that mimics extreme behavior in Nature, ranging from high temperature superconductivity to the behavior of fundamental particles in the Big Bang,when the universe is believed to have begun in a huge burst of energy within a very small space. Although the gas was trapped by a laser beam within billionths of a degree of absolute zero, the lowest possible temperature, researchers said it behaved like a superfluid flowing at high temperatures. |

'The models we're developing will allow the Navy to predict whether or not whales are likely to be in testing areas on days when sonar tests are planned,' says Andrew Read. |

Simply asking survey participants if they intend to exercise or use illegal drugs in the near future can result in increases in both behaviors, according to researchers at Duke University, the University of Pennsylvania and Baruch College.
These findings should serve as a warning to public policy and health behavior researchers who routinely use surveys as a method to study risky behaviors, the researchers say. |

-dimensional ultrasound probes built by researchers at Duke’s Pratt School of Engineering have imaged the beating hearts of dogs. The engineers said their demonstration showed that the probes could give surgeons a better view during human endoscopic surgeries in which operations are performed through tiny “keyhole” incisions. |

“If I tell you there’s an island the size of Greenland, and I have buried 600 treasure chests somewhere on the island, you know nothing,” Hartemink explains. “We’ve identified genetic regions, or parts of the landscape, that are more likely to be where the ‘treasure’ of imprinted genes is buried. In that sense it’s like a treasure map.” |

Human activities have caused some 500 bird species worldwide to go extinct over the past 500 years, and 21st-century extinction rates likely will accelerate to approximately 10 additional species per year unless societies take action to reverse the trend, according to a new report. |

In light of the surgeon general's recent report on secondhand smoke, it's clear that the smokers aren't the only ones who bear the cost of their habit, says a Duke University health policy researcher. |

When a team of Duke researchers published a list of genes likely to contribute to human ailments ranging from Alzheimer’s and autism to diabetes and obesity, it shed light not only on diseases that afflict millions of people but also on how research that may lead to new treatments and cures is changing across the university. |

Tuan Vo-Dinh, a pioneer in the field of photonics at Oak Ridge National Laboratory, has joined the department of biomedical engineering at Duke University’s Pratt School of Engineering, where he will serve as director of the Fitzpatrick Institute for Photonics. |

Researchers at Duke University’s Fuqua School of Business have identified a pattern of behavior that provides new insights into the failure of business and government leaders to correct or cancel failing projects that initially had been expected to succeed. |

Researchers led by a Duke University psychologist have developed a new type of psychotherapy that is optimally designed to treat a particular type of depression. The new self-system therapy targets patients whose depression is linked to difficulty identifying and pursuing goals involving advancement, growth and achievement, according to Timothy J. Strauman, a co-developer of SST who is professor and co-chair of the Duke Department of Psychology and Neuroscience. About one-fifth of depressed patients fit this profile, Strauman said. |

Using a chain of molecules as an infinitesimal lanyard to tug on a chemical bond about to break, Duke University chemists have found they can speed a complex chemical reaction. |

The recent removal of high-profile pharmaceutical treatments from the market has focused the public’s attention on drug safety efforts by companies and the Food and Drug Administration. |

Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. Once devised, the cloak could have numerous uses, from defense applications to wireless communications, the researchers said. |

Scientists at Duke and Rutgers universities have developed a mathematical framework they say will enable astronomers to test a new five-dimensional theory of gravity that competes with Einstein's General Theory of Relativity. |

It turns out that parents are right to nag: To succeed in school, kids should do their homework. Duke University researchers have reviewed more than 60 research studies on homework between 1987 and 2003 and concluded that homework does have a positive effect on student achievement. |

Natural disasters such as mudslides and tsunamis bring massive media attention to impoverished nations, but the enduring problem of public health in those countries receives much less notice yet continues to endanger millions of lives each year. |

After an exhaustive data search for new compounds, researchers at Duke University's Pratt School of Engineering have discovered a theoretical 'metal sandwich' that is expected to be a good superconductor. Superconductive materials have no resistance to the flow of electric current. |

Duke University theoretical chemists are investigating a new computer method that could help scientists identify the best molecules for drugs, electronic devices or an array of other uses. Their method would address the 'daunting' fact that 'that there aren't enough atoms in the universe to make all the reasonable-sized molecules that could be made,' said Duke chemistry professor David Beratan. |

Predators are, ironically, the key to keeping the world green, because they keep the numbers of plant-eating herbivores under control, reports a research team lead by John Terborgh, a professor of environmental science at Duke University’s Nicholas School of the Environment and Earth Sciences. |

Cognitive neuroscientists have shown that babies have an abstract numerical sense, as demonstrated by their ability to match the number of voices they hear to the number of faces they expect to see. This numerical perception across senses demonstrates that babies have a truly abstract sense of numerical concepts, and not just one that is a function of a particular sense, even before they learn to speak. Previous experiments on this topic have yielded conflicting and equivocal results, said the researchers. |

By changing individual atoms in key places in proteins, Duke University chemists have found new evidence for the importance of comparatively weak 'hydrogen bonds' in enabling stringlike proteins to fold into the maximally stable shape they need to assume their roles as biological workhorses. Such protein folding immediately after proteins are synthesized is central to their function in the cell. |
