The War in 1812
While Republicans, for the most part, still backed Jefferson's foreign policies, new elections were transforming the party. Older politicians who molded the Republican Party policy and put Jefferson and Madison in power were replaced by daring young go-getters, such as Henry Clay of Kentucky, who were intent on defending America's honor. These new leaders, called "War Hawks" by their Federalist opponents, were the primary force behind Madison's decision to call for war with Britain. The War Hawk

3.2 Io

Io is one of the most marvellous bodies in the Solar System, but the intense radiation bathing its surface (Figure 2) makes it unlikely that anyone will ever be able to visit. Even robotic spacecraft cannot survive this close to Jupiter for very long, so the Galileo Jupiter orbiter made very few close fly-bys of Io.

Until now, screening programmes have focused on one gene at a time, or one disease at a time, in cases where a mutated gene poses serious health problems and something can be done for those who are found to carry the mutation.
