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...

...predictable response to this, of course, is the claim that 16-celled—or eight-celled, or whatever number seems sufficiently small—embryos are not human beings at all. After all, we are told repeatedly, they are just a “clump of cells,” and killing them is no different from disposing of a patch of dry skin or clipping your toenails. Besides, they’re in petri dishes, and what kind of human beings live in petri dishes? Not you or I, certainly. Embryos don’t have feelings, they...
...MILL THE SPORES Once the spores are dry, they are ground down to the smallest possible particle size, anywhere from one micron (one spore) to 20 microns. The process adds electrostatic charges to the particles, which makes them clump together...
