...ry for such mutualistic interactions. "I develop theoretical
models, equations that attempt to explain mutualistic relationships like the one between the moth and the cactus, and I take those models into the field and examine them empirically to find out how well they predict what really happens," Holland said...

...unction are currently not well understood. Several theoretical
models are available, but empirical data and detailed measurements of brain processes in humans are still rare. In the last years of research evidence has accumulated to regard the brain as a parallel system with highly specialized compartments, so t...

physicist Susan Coppersmith, the group turned to modeling to try to understand how such a structure could form. "By looking at the final result and comparing it to the result of different growth models, you get insight into what the actual mechanis...
