Nanorobotics is a scientific discipline gaining in popularity due to the numerous possibilities it provides. Materials science, space exploration, ecology, information technology, electronics, and communications are just a few of the domains where nano-robots can be used. Military weaponry and applications, on the other hand, are being transformed by these new nanorobotics applications. As a result, after a brief introduction to nanoworld theory, the remainder of this article focuses on military applications. The most recent breakthroughs in the military application of nanorobots have been summarised in this report. Military nanotechnologies have been suggested as more devastating weapons than nuclear weapons for the entire planet, with the potential for application in all military locations, due to their fundamentally revolutionary benefits.

AbstractMilitary enlistment is highly selective for reasons of both labor demand and supply. An early-twentieth-century evolution of military technology that shifted the demand for workers of different stature illustrates the importance of labor demand beyond the commonly discussed influences originating with labor supply. English-born soldiers in the Anglo-Boer War (1899–1902) were taller, on average, than those of World War I (1914–18), yet these differences cannot be attributed to standard of living or business cycle influences on the labor market. Rather, we argue, the mechanization and bureaucratization of warfare increased the relative value of shorter people permitting a decline in the average height of soldiers. Technological change over the period of these two wars affected labor demand in a way that must be recognized before using this evidence to test hypotheses about changes in population health.
