Dealing deadly cancers a knockout punch

... four of five test animals. It is rare to see the virtual elimination of tumours as well as the long-lasting therapeutic effect that was observed in this study. "Combination therapy results for reovirus in animals are particularly encouraging because they suggest that Reolysin can improve the anti-tumor ...

Pacific Rim researchers to collaborate on distributed bioinformatics analysis of avian flu

...ontribute its natural compound database for use in virtual screening for new inhibitors and drug discovery. CNIC will also become the central repository for the project’s research data. The database will be distributed through the computational data grid, and accessible through web portals mirrored at...

The influence of the menstrual cycle on the female brain

Virtual duck bills demonstrate species coexistence

...rger particles." To test his idea, Gurd created virtual bills using computer software typically used by engineers to design complex machinery. "The software allowed me to create exact, three-dimensional replicas of duck bills complete with articulating joints" said Gurd. "The replicas allowed me to determ...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...sts ?within a community of 50,000. Members of this virtual community interacted the way people normally do: within households, neighborhoods, preschool groups, schools, a community hospital and the community at large. The age distribution and household sizes were based on the U.S. census for 2000. Predicti...

Where we change our mind

... aim was to analyze subjects' navigation through a virtual maze, to explore how different cortical regions function in solving "partially observable decision-making problems." "In navigation tasks, such as that investigated here, an individual must constantly maintain an estimate as to his/her current locat...

Air travel and pandemic flu

... flu outbreak in 1968?969. Using this information, virtual experiments were carried out by simulating worldwide outbreaks on a computer. The researchers looked at how the virus might spread from one city to another and how travel restrictions might reduce the rate of spread. Their calculations allowed for su...

Researchers discover how bacteria sense their environments

They discovered that even a crude network dramatically improves infrared imaging - which you might want to keep in mind if you ...

A new look at the state of the oceans

...Sciences (WDC-MARE). This data centre represents a virtual institute and is administered by the Alfred Wegener Institute and the Centre for Marine Environmental Sciences. Aside from WDC-MARE, there are more than 50 other global data bases worldwide that serve as long term archives and provide information for...

On the track of tiny larvae, a new model elucidates connections in marine ecology

...n ocean currents, while the second model gives the virtual larvae a genetic tag. The researchers then tested this new approach by comparing the new model's predictions to empirical genetic data for threatened staghorn corals. This test showed that combining the oceanographic and genetic models allowed the re...
