That lumpiness, reasoned theorists, must have evolved from some original lumpiness in the primordial cloud of matter that gave rise to the background radiation. Slightly denser knots of matter within the cloud--forerunners of today's superclusters--should have been slightly hotter than average. So some scientists began looking for subtle hot spots...
...women with much greater frequency than men--in some studies as much as four to six times as often. But that's no reason to brush it off as "their" disease. It's a mere stroke of gender luck that men's bones tend to grow larger, stronger and denser. Also paying dividends are those sports that boys (and, increasingly, girls) play as children--running up and down basketball courts, soccer fields and baseball diamonds. As it happens, physical activity is one of the more important ways to increase bone density and protect bone health...
...issue this warning to all students intending to enroll in History 1653: "Baseball in American Society"-- Professor of History William E. Gienapp now has the ammunition to make his lectures even denser than they were before. It has been 44 years since a National League team and an American League team have met in a Subway Series. The historic moment has finally arrived...
...high Arctic rise just a few degrees, the sea ice could disappear entirely, but even a partial melting could devastate the northern hemisphere's climate. A combination of melting ice, increased precipitation and runoff from melting glaciers on land could leave a layer of buoyant freshwater floating atop the denser salt water, at a point in the North Atlantic where water ordinarily cools and sinks. The lighter freshwater wouldn't sink, interrupting the vertical circulation at a crucial point in the cycling of heat through the ocean--as if you're grabbing a conveyor belt and slowing it down...
...argument hinges on the Gulf Stream, the ocean current that brings warm surface water north and east and heats Europe. As it travels, some of the water evaporates; what's left is saltier and thus denser. Eventually the dense surface water sinks to the sea bottom, where it flows back southward. And then, near the equator, warm, fresh water from tropical rivers and rain dilutes the salt once again, allowing the water to rise to the surface, warm up and begin flowing north again...
