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 -
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 -
Meteorologists See Future of Increasingly Extreme Weather Events
While raising average global temperatures, climate change could also bring more snow, harder rain, or heat waves, meteorologists say. Computer models based on climate data from nine countries ... > more -
Environmental Engineers Detect Turbines' Turbulence Effects
Wind farms may have an impact on local weather patterns. As environmental engineers have discovered, wind farm propellers create a lot of turbulence in their wake, mixing air up and down with effects ... > more -
Mechanical Engineering Students Develop High-Altitude Reconnaissance Airships
On a shoestring, and with off-the-shelf components, students are designing prototypes of robotic blimp that could one day be used by the Pentagon. Cheaper than spy satellites, blimps can hover in ... > more -
Meteorologists Can Now Issue Precise Local Excessive-Heat Warnings
Heat kills more people than tornadoes, hurricanes, lightning and flash floods -- combined. The National Weather Service now gives heat-wave warnings to better forecast local conditions for 16 ... > more -
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 -
Atmospheric Chemists Show Morning Fog Captures Particulate Matter
While it hassles commuters, morning mist removes a lot of airborne particles which are hazardous for people with respiratory health problems. The water droplets inside morning fog are of just the ... > more -
Meteorologists Use Weather Knowledge to Predict Path of Toxic Spills
Homeland security officials are tapping researchers' capability to predict the paths of toxic waste spills and hazardous airborne particles. Using computer science and mathematics, along with ... > more
