Wilson has suggested that the methodological orientations of the political science discipline might account for political science' s lagging behind history and sociology in the publication of mainstream journal articles on African American topics. He explained these relative disciplinary differences regarding publication as partially resulting from pressure to do large-scale voter studies; this pressure placed those interested in African American politics at a disadvantage, because the relevant empirical data on the Black population were insufficient to render findings that were externally valid and generalizable. Wilson' s second explanation pointed to the discipline' s traditional focus on politics and decision-making processes at levels to which African Americans have historically had limited access—a narrow focus reflected in the types of research articles favored in mainstream political science journals.

Researchers suspect that meteorites (particles of matter that fall to Earth' s surface from space) are pieces of asteroids, the many minor planets primarily inhabiting the region between Mars and Jupiter called the asteroid belt. The most common meteorites are ordinary chondrites-rocks containing tiny flecks of metal. By analyzing the spectrums of sunlight reflected by asteroids to determine the asteroids' chemical composition, researchers have found that most of the brighter asteroids contain the same silicates and other compounds that dominate chondrites. These silicaceous, or S-type, asteroids are the most abundant type in the inner asteroid belt, the part of the asteroid belt from which objects are most likely to escape and travel to Earth. However, S-type asteroids reflect red and infrared light much better than they reflect green, blue, and violet light, suggesting that they have a higher metal content than do ordinary chondrites. This has led at least one researcher to posit that meteorites come from other types of asteroids that are too small and too dim to be detected. However, S-type asteroids could be ordinary chondrites that have been weathered by the effects of the space environment, making them seem redder and more metallic than they really are.

Ecologists tend to focus on pristine environments and ignore urban areas. Human beings, and especially their cities, fail to fit neatly into ecological theory-they are seen as an exogenous, perturbing force in nature. Yet people are a global force capable of affecting every ecosystem on the planet. In cities, people mobilize some nutrients and deplete others, create habitats that never before existed, increase temperatures, and, by intent or by accident, manipulate the communities of other species found within city boundaries and beyond. If there is a laboratory where ecological change can be viewed at close hand, it is the city. The processes and dynamics within cities, however, largely elude understanding based on traditional ecological theories.
