...truth about Bush that he prefers to guide by the big picture and the bottom line. While Gore enjoyed playing at the molecular level, Bush is annoyed by it. Every aide tells you this is the key to understanding his leadership approach. And it is the way to understand how he rules the ranch too. The stuff has to be cleared to get the broader view, cleared so that you can see from the land on top of his property down into the greener valley. We stop at an overlook he has just thinned out so that he can show...
...invaded our DNA and became a permanent part of us. Says Smith: "We hope over the years to get a clear picture of how our genome was put together and even see where it might be going." Not just how, but when. For example, the genome evidently contains a molecular clock in the form of sequences of letters that are repeated between the genes and have mutated over time. The rate of these changes could serve to time-stamp specific traits. We may someday be able to pinpoint the epoch in which the traits that make us uniquely human emerged...
Once activated, the T cell transforms itself into a sort of commander-in-chief of immunity, activating the B cell-which secretes antibodies-and prompting the release of a farrago of molecular signals that lead to inflammation...
Drugs are molecular saboteurs. They exert their curative effects by gumming up the works of key proteins in the body. The compounds with the fewest side-effects are the ones that drop their monkey wrenches selectively, slotting into grooves on the surface of their target proteins-and no other proteins-as snugly as feet fit into socks...
...design drugs that choose their targets this efficiently. In fact, it’s so difficult that drug companies have hardly ever tried. They’ve relied instead on trial and error, testing hundreds of potential drugs in animals to find a few that actually cure without killing. But these molecular crapshoots are terribly wasteful, which is why drug designers are today turning to a computer science known as bioinformatics to fuel their endless quest for newer drugs and better targets...
