Gage now believes that changes in behavior--like exercising more--can affect neurogenesis and alter the brain's wiring. "The idea is that we have control over who we are, even as adults," he says. We're used to thinking that our minds control our bodies. Could it be the other way around? Could what we do change the structure of our brains? It's a radical idea--one that turns on its head accepted ideas of nature vs. nurture. And since Gage has some experience toppling long-standing biological truths, it's probably worth considering...
...long history of failure. Dr. Nicholas Pace, co-founder of the Alcoholism Council of New York, agrees that such experiments are doomed because alcoholism, as abstinence advocates have drummed into the public's consciousness, is a disease. People who drink heavily over a long period of time permanently alter their livers, which means that they can no longer metabolize alcohol normally in the event that they do resume drinking. "The disease is progressive," says Pace. "If you put people on an island and give them alcohol every day, they will become alcoholics...
...issue that is now on the front burner dates back to 1992, when the FDA decided that biotech ingredients did not materially alter food and therefore did not require labeling. Nor, the agency declared, was premarket safety testing required, because biotech additives were presumed to be benign. Last March the Center for Food Safety and 53 other groups, including the Union of Concerned Scientists, filed a petition to force the FDA to change its policy...
...tossing sweet guys into wildly frustrating situations. Carrey plays Charlie, whose wife has left him with three fat black babies (we'll explain another time); he smiles and copes. But by repressing his rage, Charlie has let a demon grow inside him; finally it bursts out in an alter libido named Hank. That makes him bad company for Irene (Renee Zellweger), whom he must escort to upstate New York. You see, he's fallen in love. Both...
...swallowing them. They could also be directed to leave, so the process should be easily reversible. They will be programmable, in that they will be able to provide virtual reality one minute and a variety of brain extensions the next. They will be able to change their configuration and alter their software. Perhaps most important, they will be massively distributed and therefore can take up billions or trillions of positions throughout the brain...
