Women well informed about breast cancer, yet lacking knowledge about current treatments

...erage, women with breast cancer would benefit from more information about advances in treatments after surgery.” According to the survey, nearly all respondents were aware of chemotherapy and radiation. However, fewer than one out of four had heard of newer therapies such as aromatase inhibitors or mo...

Australian wins prestigious prize in biodiversity informatics

...hical areas. This helps biodiversity scientists be more efficient in their efforts to discover and conserve species. The GBIF Science Committee noted when it announced the 2007 Prizewinner, “Paul Flemons has been a key figure in developing a robust and accessible biodiversity data infrastructure that...

Genetic factors are linked to fever following smallpox vaccination

...igned to identify ways we might make vaccines even more acceptable in the future by discovering ways to further reduce the chance of minor adverse events.” In an accompanying editorial, James E. Crowe Jr., MD, of Vanderbilt University Medical Center, echoes Dr. Stanley’s sentiments that the findings ...

Small, self-controlled planes combine plant pathology and engineering

...entland Farm, Schmale and his colleagues collected more than 500 viable colonies of Fusarium, representing at least a dozen species. “For 11 of these Fusarium species, this is the first report of their ability to be transported great distances above the surface of the earth,” Schmale said. “Our work ha...

The experiments looked at how the chimpanzees used rakes in order to retrieve a fruit yoghurt reward. The overall study examined not only whether the chimpanzees understood the properties of the ...

"With other techniques, you can usually incorporate only one copy of your gene cargo to each bacterium or virus particle," Akin said. In the new approach, bacteria can car...

...del, such as a pig, which has a coagulation system more similar to that in humans. The advantage of our approach is that the graft could utilize the patient’s own stem cells and be ready for implantation almost immediately or, at most, after a relatively short culture period. This suggests that we could m...

Oscillation can become chaotic in states of consistent lighting or lack of lighting, but it never stops. Comparing the complex system in which the genes function to an AC power...
