This is not to say that these and other studies, taken together, suggest that vaccines don't work for the elderly. The answer is a question mark. We don't know what protection, if any, vaccines offer. I don't think that's a bad thing. Uncertainty is the motor of science. We need large studies to find...
Some experts have suggested that the grizzlies might not stick around long enough to face off with the polar bears, says Rockwell, but he isn't buying that. The 4,000-plus-sq.-mi. park where hunting is banned is what Rockwell calls a "food mecca" for grizzlies.

He admits that the role of Goldman Sachs and other major banks in helping Greece disguise its mounting debts...
Begg sees a deeper purpose behind the blame game, as politicians try to mitigate the public criticism that will accompany the inevitable austerity measures needed to fix the Greek and Spanish economies. "There is an Italian concept of vincolo esterno, or external constraint," he says. "It is a device a canny politician can use to say, 'We must do this or we will be eaten alive.' Although the conspiracy theories are preposterous, they help prepare for the reforms which are needed...
