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

Wind Farms Impacting Weather
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

Mechanical Engineers Create High-tech Solar Panels
Photovoltaic panels have a new design: concentric circles that focus the sun's rays on miniaturized modules. Having the panels automatically sense sunlight and turn towards it also makes these ... > 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 -
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 -

Biological Engineers Generate Natural Gas with Bacteria
A new kind of waste digester uses two different strains of bacteria in different tanks. This would normally take place in the same environment, but microbiologists have now separated it into two ... > more -
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 -
Meteorologists Discover How Monsoon Affects Summer Weather
Traveling to the coast of Western Mexico, U.S. researchers are studying the North American Monsoon, which brings humid air and heavy rain by blowing winds from the ocean. Studying the monsoon will ... > more -

Engineers Create Recycling Plant That Removes The Need To Sort
Engineers use the term single-stream recycling for their plant that takes the sorting out of the public’s hands. Trucks dump an unsorted mess of paper, plastic, and metal onto a conveyor belt. ... > more -
Physicist Explains Benefits Of Carbon Dioxide
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 dioxide levels. ... > 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 -
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
