Physicists Show "Antigravity" Mystery Spots Are Optical Illusions
At several hilly locations around the U.S., know as "gravity hills," objects such as cars left on neutral supposedly roll uphill, driven by unknown forces and against the force of gravity. Physicists ... > more -
Exhibit Makes Big One's Risks Tangible
At San Francisco's Exploratorium, a scaled-down model of the city made with Jell-O helps visitors visualize how the city would shake during a major earthquake. In another display, a bowl filled with ... > more -
Meteorologists Are Getting Better at Forecasting
The U.S. experiences more severe storms than any other country in the world. Recent improvements in forecasting technology -- especially in computer simulations have brought five-day weather ... > more -
Meteorologists Describe Little-Known Giant Windstorms
Derechos are elongated, straight-lined windstorms that often have bands of rapidly moving thunderstorms associated with it. These little-known atmospheric phenomena often stretch for hundred of miles ... > more -
Veterinarians Show Consoling Dogs Does Not Relieve Their Panic
A new study shows that dogs can get very upset during thunderstorms, whether or not their owner holds them. The study measured the stress hormone cortisol to be up to three times normal levels while ... > more -
Environmental Engineers Replace Chemical-Laden Building Insulation with Recycled Denim
A medical center is insulating its walls with recycled blue jeans instead of fiberglass. The new construction material is more environmentally friendly, as fiberglass contains formaldehyde, which is ... > more -
Meteorologists, Atmospheric Scientists Fly Through Storms to Gather Data
During hurricane season, scientists fly aboard NOAA aircraft to pinpoint the precise path of the eye of a storm, and to take data to send back to the National Hurricane Center. The planes are now ... > more -
Meteorologists, Atmospheric Scientists Perfect Next-Generation Weather Simulation
Three severe hurricanes hit the U.S. in 2005. Weather forecasters now hope to reduce the loss of lives caused by hurricanes with better computer modeling. With more precise predictions of a storm's ... > more -
Meteorologists, Wind Engineers Standardize Fujita Scale
The Fujita Scale rates tornadoes based on the damage inflicted upon buildings, so accurate rating requires knowing how resistant buildings were in the first place. Starting February 2007, the ... > more -
Physicists, Engineers Capture Lightning with Tethered Rockets
To study lightning, scientists use rockets connected to the ground by wires. They fire the rockets into clouds, triggering electrical discharges, and storing their power. They have found that ... > more
