Cool Pacific Waters May Not Affect Upcoming Hurricane Season
Like their more dramatic cousins El Niños, La Niñas -- the periodic cooling of ocean waters -- can have a dramatic impact on hurricanes, meteorologists say. The current La Niña, ... > 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 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 -
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 -
Scientist Measures Land Used by Lawns
Using census data, satellite images, aerial photographs, and computer simulations, a NASA scientist estimated that turf grass is the single-largest irrigated crop in the United States, three times ... > 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 -
Environmental Toxicologists Link Household Bacteria to Asthma
Scientists have found that chemicals called endotoxins can inflame airways and trigger asthma. Endotoxins are shed by bacteria in household dust. Experts say better home hygiene, washing bed linens ... > more -
Environmental Engineers, Water Scientists Develop Children's Kit for Monitoring Water Health
Playing a role once reserved for environmental engineers, children are now helping to test the health of water in their local communities. A new kit comes equipped with everything needed to test the ... > more -
U.S.G.S., Caltech Seismologists Develop Online Tool to Predict Aftershocks
With a new online map, scientists can better forecast when and where aftershocks may happen. The maps calculate information based on historical earthquake patterns and known behavior of aftershocks. ... > more
