Disaster Experts Map Risk Across the Nation
Disaster experts including meteorologists and seismologists have identified the types of catastrophic events the United States is most likely to face, quantifying the risk of earthquakes, urban ... > more -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > more -
Are Bioluminescent Bacteria Behind Milky Seas Legend?
For centuries, sailors in the Indian Ocean have told stories of seas glowing with a dim, white light at night. Satellite images have now confirmed the appearance of what seem to be bioluminescent ... > more -
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, 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, 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 -
Seismologists Use Ultrasounds to Assess Quakes Faster
Using ultrasound imaging, seismologists can now determine the epicenter and magnitude of an earthquake quake within 10 to 20 minutes, precisely imaging which fault ruptured and where the rupture ... > more -
Space Physicists and Atmospheric Scientists Can Now Predict Disruptions Caused by the Sun's Coronal Mass Ejections
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track ... > more
