...Sunspots tend to travel in pairs or groups of opposite polarity, like the ends of horseshoe magnets poking through the solar surface. During one eleven- year cycle, as the blemishes traverse the face of the sun in an east-west direction, the leading spots of each group in the northern hemisphere will generally have positive polarity, the trailing spots negative. In the southern hemisphere, the leading spots will be negative. During the next cycle, the hemisphere polarities will reverse. On average, then, 22 years will pass between solar maximums of the same sunspot polarity. This suggests to many astronomers that...
Most explanations of that phenomenon liken the sun to a dynamo. Mighty currents of electricity flowing in the solar interior generate magnetic-field lines that, like the earth's, tend to be oriented in a north-south direction. But because the sun, unlike the earth, is gaseous, it does not rotate uniformly: bands of gases around the equator circle the solar axis once every 27 days, compared with a 34-day rotation rate near the poles...
...careful not to extend my reach where I'm not welcome or where it's not really part of my role because one can tend to do damage there," she told a Crimson reporter...
Treatment patterns can vary among communities because doctors in different places have different methods. Within a given hospital, doctors tend to consult one another and reach a consensus on how to practice, but that consensus may not be the same in another city. In some areas, for example, the frequency of hysterectomies is three times as high as in other places. As discoveries like these accumulate, statistical evidence begins to raise doubts about the scientific certainty usually associated with medicine...
...iron fence that separates man and animal. With a deft twist of his heavy, pointed lips, Macho plucks a slice of apple from Bentsen's hand. Bentsen reaches through the bars to scratch the leathery muzzle. Rhinos are slow-witted, almost childlike creatures that when startled tend to charge first and ask questions later. But once it knows your voice, a captive rhino can be called like...
