...a combined satellite remote sensing and vegetation modeling approach. "The symposium will comprise of 22 talks and 6 poster presentations, and conclude with discussion of the main scientific questions that need addressing and how this international research can be funded in the future in a joined up way."...Predicting species abundance in the face of habitat loss

"It's likely that the forces between S-layer proteins are highly anisotropic, and we suspected this was also a feature of the nanoparticles," Glotzer said. "Computer simulations allowed us to further develop and tes...Yale and NFCR launch Research Center for Cancer Drug Design and Discovery

...ni and colleagues rely on a tool called stochastic modeling to take into account real-world unpredictability, as well as many factors about the disease and the affected population. In constructing these models, Longini and colleagues begin with assumptions about how people interact and how the virus spreads. ...Researchers reveal mystery of bacterial magnetism
...searcher Dr. Paul Sheehan adds, "by mathematically modeling their motion, we determined that being magnetic actually makes the bacteria much more sensitive to oxygen when in a magnetic field, so that they swim away from oxygen at much lower concentrations." It is as if the climber gets tired and turns around...Researchers add to understanding of how brain cells communicate

They used computer modeling to show that variation in how ions interact with receptors combined with variation in the structure of receptors is responsible for specialization of receptor function.
