Ten years after terrorists slammed a pair of fuel-laden jetliners into the iconic twin towers in lower Manhattan, engineers around the world are designing stronger skyscrapers to resist the worst that nature and evil minds can throw at them.

A prime example is 1 World Trade Center under construction at Ground Zero itself.

The sky-piercing, 1,776-foot-tall spire takes into account everything investigators learned from the collapse of the World Trade Center’s twin towers on Sept. 11, 2001, making it “an outstanding building for terrorist resistance,” said Gene Corley, a lead investigator of the federal study and a vice president at engineering firm CTL Group.

8.7 ideas in earthquake prediction

Earthquakes are notoriously difficult, if not impossible, to predict. “You are dealing with a very complex physical system that behaves very differently in many places,” says David Schwartz, a geologist with the U.S. Geological Survey’s San Francisco Bay Area Earthquake Hazards Project. Nevertheless, researchers are trying to improve earthquake probability forecasts and working toward, maybe one day, prediction and prevention. Learn about eight of their ideas.

Wouldn’t it be nice if airline pilots turned on the “fasten seat belt” sign before the person standing in the aisle toppled onto your lap because of turbulence?

Publication: National Geographic News   Date: December 6, 2006   View Article

Beginning today pilots will have more reliable information about the threat of dangerous icing conditions as they fly across the continental U.S.

The information could save the airline industry more than $20 million a year in aircraft damage and fuel by guiding pilots away from areas in the atmosphere where icing can take place, according the National Center for Atmospheric Research (NCAR) in Boulder, Colorado.
