What's In Our Air?
Spectroscopic images from
remote-sensing satellites of
the Ohio River Valley over
10 years have revealed a
decreasing concentration of
nitrogen oxides and nitric
acid, precursors to ozone. ... > full story
Fog Cleans Air Pollution
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

Can Carbon Dioxide Be A Good Thing?
A physicist from Colorado
State University and his
colleagues from the North
American Carbon Program
(NACP) have discerned and
confirmed the unforeseen
advantages of rising carbon

Atmospheric Scientists Monitor Global Carbon
With the annual, steady increase of global warming and carbon discharge, atmospheric chemists are gathering air samples on behalf of the National Oceanic Atmospheric Administration (NOAA). Air ... > more -
Environmental Scientists Find Tree Combo For Carbon Sequestration
A research team found 31 hardy trees that sequester carbon efficiently for the New York region, mitigating against the impacts of high deforestation and carbon release into the atmosphere in that ... > more -
Environmental Engineers Link Contamination Levels to Tides
By washing decomposing plants into the ocean, high tides could contribute to the increased levels of Enterococci that are often responsible for beach closures. Scientists have now established a clear ... > more -
Statisticians Show that High Altitude Makes Hits Longer
Two mathematicians at the University of Northern Colorado are taking a fresh statistical look at the effects of elevation on hitting -- specifically at Coors Field in Denver, where the field is at a ... > 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 -
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 -

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 -
Environmental Engineers Use Algae To Capture Carbon Dioxide
Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae. A team at Ohio University created a photo bioreactor that uses photosynthesis to grow algae, ... > more -
Environmental Scientists Use Fish Behavior To Monitor Water Quality
Researchers are using bluegills to detect industrial and agricultural spills in water supplies. Changes in the environment cause the fishes' behavior and breathing patterns to change. Electrodes are ... > more -
Environmental Engineers Replace Chemical-Laden Building Insulation with Recycled Denim
A medical center is insulating its walls with recycled blue jeans instead of fiberglass. The new construction material is more environmentally friendly, as fiberglass contains formaldehyde, which is ... > more
