...shortcomings of fMRIs may be more serious. Physical anomalies such as evidence of a stroke or tumor can interfere with the scan's accuracy. And the test is administered in a decidedly unnatural way--with the subject lying down inside a giant magnet. Since speaking aloud activates regions of the brain that could swamp lie-detection results, subjects are asked yes-or- no questions and then instructed to push a button to answer. Maybe the brain operates the same way with a push-button fib as with a verbal one--but maybe it doesn't. And because...
...Coumadin is the "blood thinner" we use when you've had a stroke, heart valve replacement or blood clot. It works by poisoning an enzyme in your liver that helps produce clotting factors. Its blood thinning (anticoagulating) effect comes on slowly but can quickly become (dangerously) greater than we want when you take different drugs or even different foods. The anticoagulation we want can easily overshoot - with dire consequences. It also can render ineffective or too effective, other drugs that are processed in the liver. Getting you on just the right dose of coumadin takes about a week, then...
...Music button on the phone's right side is a stroke of convenience. Unlike other quick-access buttons I've seen, this one allows you to toggle.

Added Massachusetts Congressman Ed Markey: "This will be remembered as a Luddite moment in American history...
Elected Prime Minister in March in the wake of his predecessor Ariel Sharon's debilitating stroke, Olmert, 60, did not expect to define himself in this way--through the most dramatic outbreak of cross-border Arab-Israeli violence since the 1982 invasion of Lebanon. Voters brought him to power not as the man best equipped to fight Israel's enemies but as one explicitly committed to disengaging from Israel's foes, to walling them off by establishing borders demarcated by an imposing fence. Hizballah's incursion into Israel two weeks ago, in which eight soldiers were killed in addition...
