...right behind the horses. That always happens in Vermont--it's a message, I guess. You have to watch your step, which is a pain because you want eye contact with the people." When the parade begins, Dean takes off--running, and I mean sprinting--from clump to clump of parade watchers. His face grows red; he sweats; people hand him Dixie cups of water as if he were in a marathon. John Kerry, by contrast, occasionally breaks into a stately jog, from one side of the street to the other...
...right behind the horses. That always happens in Vermont-it's a message, I guess. You have to watch your step, which is a pain because you want eye contact with the people." When the parade begins, Dean takes off-running, and I mean sprinting-from clump to clump of parade watchers. His face grows red; he sweats; people hand him Dixie cups of water as if he were in a marathon.

Precisely how these powerful chemicals affect the course of heart disease, cancer and other illnesses isn't well understood yet, but preliminary research has yielded some tantalizing clues. When serotonin circulates in the bloodstream, for example, it appears to make platelets less sticky and thus less likely to clump together in artery-blocking blood clots. For years, heart-attack survivors have been advised to take a children's aspirin daily for clot prevention; such drugs as Prozac, which keep serotonin in circulation, seem to have a similar effect...
Because of the current size of these catalyst particles, about 10 nm, and their tendency to clump together, platinum is not used efficiently. The world's entire annual output of platinum would not meet the demand if fuel cells were used by only 10% of cars produced worldwide. Hydrocarbon Technologies--which is owned by Headwaters, an alternative-energy company based in Draper, Utah--says it has found a way to create nanoscale platinum particles that won't clump together and slow down the process, as current ones do. The new particles are expected to keep fuel cells running...
...such an arrangement could just create seminars that have little student interest—continuing the tendency of students to clump around a few offerings...
