Growing Greener Lawns
Chemists and engineers
designed a technology that
protects soil. A polymer
encased in recycled paper
bonds to positive ions in
soil to form clumps. These
clods of dirt break up the
hard surface that can form

Danger in Your Backyard
Planting ferns can be a
cheaper, greener way to soak
up poisons such as arsenic
from the soil. Ferns absorb
arsenic through their roots
and store it in their
leaves, which can then be

Saving Marshes - Saving The Planet
Soil scientists spread
material dredged from
shipping channels over shore
areas to help rebuild marsh
areas. Wetlands along the
shore protect the land from
storm surges, create habitat

Building Better Dams
A group of U.S. civil
engineers and city officials
went on a recent trip to the
Netherlands -- a country
much of which is below sea
level -- to study the
country's storm surge
barrier system. The system

Using Radar, Meteorologists See Increase in Hurricane-Made Tornadoes
Tornadoes can form when hurricanes make landfall, as their winds at ground level slow down, while the winds near the top keep their momentum. Data from 2004 show this tendency seems to have ... > more -
Improving Structural Engineering with Earthquake Simulator
To develop designs that can survive extreme seismic events, and to devise retrofit solutions for older homes, civil engineers who specialize in structural design test realistic models of homes in ... > more -
Civil Engineers Improve Houses Against Hurricanes
Polystyrene blocks used to build the walls in the home have survived a direct hit from a tornado, and improved version used in houses incorporates concrete with steel reinforcing inside. On a ... > more -
Geologists Create Map Of Threat Of Volcanic Eruptions Throughout The United States
Geologists combined research from around the country with Google Maps to show where volcanoes could erupt in the United States. The website is constantly updated to reflect the current status of ... > more -
The Science Behind Wave Pools
Scientists gives us a sneak peek into the world of wave pools, and explain how these huge pools make constant waves. Waves are made by a huge compressor that feeds four gigantic air blowers. Then a ... > more -
Geophysicists Show That Crust Temperature Variation Explains Half Of Elevation Differences In North America
Geophysicists determined that tectonic mountain-building processes are not the only factor that determines elevation in North America. The temperature of the crust affects its density, and lower ... > more -
Physicist Calls for Airline Industry to Educate Workers about Radiation Levels
At the high altitudes and latitudes commercial airlines fly, crews are subjected to higher-than-normal radiation levels from the sun and cosmic rays. Physicist Robert Barish believes airline crew ... > more -
Geophysicists Discover Slippery Secret Of Weaker Underwater Earthquakes
Seismologists investigating undersea earthquakes have found that molten rock lubricates faults. This decreases the amount of friction between sides of the fault and decreases the intensity of ... > more -
Poultry Nutritionists Remove Pollutants From Watersheds By Adding Enzyme To Chicken Feed
Poultry nutritionists add an enzyme called phytase to chicken feed in an effort to decrease the amount of phosphorus that passes through them undigested. Research revealed the maximum amount of ... > more -
Engineers And Meteorologists Catalogue Weather Activity To Devise Green Energy Plan
Researchers installed weather stations to track the best locations for taking advantage of renewable resources. Tracking sunlight exposure helps pinpoint the ideal location for solar panels, and ... > more
