Publicly available cell-phone applications from application markets are releasing consumers' private information to online advertisers, according to a joint study by Intel Labs, Penn State, and Duke University. Researchers at the participating institutions have developed a realtime monitoring service called TaintDroid that precisely analyses how private information is obtained and released by applications "downloaded" to consumer phones. TaintDroid is an extension to the Android mobile-phone...

Duke University bioengineers have not only figured out a way to sneak molecular spies through the walls of individual cells, they can now slip them into the command center -- or nucleus -- of those cells, where they can report back important information or drop off payloads. Using silver nanoparticles cloaked in a protein from the HIV virus that has an uncanny ability to penetrate human cells, the scientists have demonstrated that they can enter the inner workings of the nucleus and detect...

While scientists have spent the past 40 years describing the intricate series of events that occur when one mammalian cell divides into two, they still haven't agreed on how the process begins. There are two seemingly contradictory theories, which now may be reconciled by a third theory being proposed by Duke University bioengineer Lingchong You. These findings could provide insights into the initiation of disease, such as cancer, which is marked by uncontrolled cell proliferation. During...

Under the microscope, the bacteria start dividing normally, two cells become four and then eight and so on. But then individual cells begin "popping," like circus balloons being struck by darts. This phenomenon, which surprised the Duke University bioengineers who captured it on video, turns out to be an example of a more generalized occurrence that must be considered by scientists creating living, synthetic circuits out of bacteria. Even when given the same orders, no two cells will behave...

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior. Contraception alters the chemical cues these scent-reliant animals use to determine genetic fitness, relatedness and individuality. And, as a sort of double whammy to birth-control efforts, male lemurs were shown to be less interested in females that were treated with...

In the record books, the swiftest sprinters tend to be of West African ancestry and the faster swimmers tend to be white. A study of the winning times by elite athletes over the past 100 years reveals two distinct trends: not only are these athletes getting faster over time, but there is a clear divide between racers in terms of body type and race. Last year, a Duke University engineer explained the first trend "“ athletes are getting faster because they are getting bigger. Adrian...

Faced with threats such as habitat loss and climate change, thousands of rare flowering plant species worldwide may become extinct before scientists can even discover them, according to a paper published today by a trio of American and British researchers in the journal Proceedings of the Royal Society B. "Scientists have estimated that, overall, there could be between 5 million and 50 million species, but fewer than 2 million of these species have been discovered to date," says lead author...

A study that examined 30 years of standardized test data from the very highest-scoring seventh graders has found that performance differences between boys and girls have narrowed considerably, but boys still outnumber girls by more than about 3-to-1 at extremely high levels of math ability and scientific reasoning. At the same time, girls slightly outnumber boys at extremely high levels of verbal reasoning and writing ability. Except for the differences at these highest levels of performance,...
