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

Tracking Pollution From Space
Engineers processed data
from NASA's Aura satellite
in order to track and
predict the movement of
airborne pollution. Using
satellite data to measure
ozone concentrations over

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 Scientists Fume About Disappearing Flower Fragrances
Biochemists have shown that air pollution inhibits the distance that flower's fragrances can travel. Scent molecules usually travel easily in the air, but pollutants break them apart, which destroys ... > 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 -
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 -
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 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 -
