New Orleans sits smack dab between the Gulf of Mexico and Lake Pontchartrain, and when a hurricane comes rolling in, those bodies of water tend to spill into the streets. This summer, the U.S. Army Corps of Engineers started construction on a barrier that can block a 16-foot swell blown in from the Gulf and a massive pumping station that will blast floodwaters back to sea.

Now bracing for category-4 mayhem means simply pulling down your shades. Storm-A-Rest manufacturer JHRG managed to turn a few pounds of .025-inch-thick fabric into stronger storm protection for windows than plywood. Faced with two-by-fours shot at 34 mph from an air cannon (one of the tests for category-4 certification in Florida), Storm-A-Rest panels survived undamaged; the boards punched right through plywood.

In London, Ontario, a team from the University of Western Ontario is bringing a fairy tale to life at the Insurance Research Lab for Better Homes. They don't have a wolf, but in their "Three Little Pigs" project they are literally trying to blow the roof off, subjecting full-scale houses to pressures that simulate wind forces matching those of a Category 5 hurricane: 200 mph. Researchers are looking to find the sources of structural weakness in house construction in order to improve building design in the future.

Tropical Cyclone Nargis slammed the Burmese coast with 130 mph winds and bursts of up to 160 mph—the equivalent of a category 3 or low-level category 4 hurricane. It reportedly led to thousands of deaths, and as of Monday, thousands more were missing. Now NASA has released a set of images that show how drastically the flooding has drenched Burma's coast.

MIT meteorologist Kerry Emanuel got a ton of attention in 2005 when he published a paper in Nature demonstrating a link between global warming and hurricanes—especially since Katrina hit New Orleans just three weeks later.
