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 -
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 -
Electrical Engineers Develop Microplasma Device to Detect Toxins
Electrical engineers have developed a new, portable lab that identifies chemicals by their unique color signatures. It is the first such device to be portable, allowing scientists to recognize ... > 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, 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 -
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 -
Entomologists Design Environmentally-Friendly Lawns, Golf Courses
The PGA Golf course at San Francisco's Harding Park is an environmental model, using fewer pesticides than any other PGA course in the country. Taking a cue from entomologists and other scientists, ... > 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
