...doctors, most headache patients are a pain because there are dozens of possible causes. With migraine patients, the problem is quite different; while sufferers can pinpoint certain triggers (food, sleep patterns, stress, alcohol), no one's really sure what exactly causes the condition in the first place. The headaches can last hours - sometimes days - and often come with nausea, vomiting, sensitivity to sound and light, and, perhaps most strangely of all, distorted sensory perception, especially vision. Add to that a link with certain other blood conditions and neurological conditions, and it's no surprise that researchers are still perplexed about...
...much is happening all at once during a migraine that it has been hard to pinpoint what sets off the trigeminal nerve. Some scientists are focusing on a wave of electrical activity that spreads across the brain just before a migraine and triggers the aura--the shimmering light show experienced by 1 in 5 migraine patients. Others wonder wheth-er there is some kind of migraine generator buried deep within the brain stem. Even when researchers think they know the order in which different parts of the brain turn on during an attack, they can't always be sure...

Behind the motives of religion and rage at Israeli occupation, Palestinian women, far more than men, tend to choose self-sacrifice as an exit from personal despair, while others are pushed into it for having broken taboos in strict Palestinian society.

Perlman only allowed one runner past first base, when Santomauro singled in the fifth and advanced on a passed ball. Perlman showed pinpoint control in his shutout gem, using his blazing fastball to strike out five while walking none. “They were behind on the fastball all day,” he said. The Crimson gave Perlman all the run support he needed in the second. Sophomore outfielder Matt Rogers doubled with...
...seems commonsensical that sleep is a restorative phase for brain and body, and there's some evidence that the effects of sleep deprivation are the result of minor brain damage that would normally be repaired when we're asleep. But despite their best efforts, scientists have been unable to pinpoint what's going on in sleep that makes it essential...
