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
Cleaning Up Our Beaches
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

Possible Fix For Global Warming?
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

Tracking 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

Meteorologists, Atmospheric Scientists Perfect Next-Generation Weather Simulation
Three category-5 hurricanes hit the U.S. in 2005 -- a record. Weather forecasters now hope to reduce the loss of lives caused by hurricanes with better computer modeling. With more precise ... > 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 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 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 -
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 -
Turning Old Plastic Bottles Into Valuable Recycled Materials
Chemical Engineers developed a way to break down plastic bottles made from polyethylene terephthalate -- or PET, and recycle it back into high value uses like more soda bottles, water bottles, beer ... > 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 -
Students Help Meteorologists Make Sense of Satellite Radar Data
One hundred schools in 11 countries are participating in a program to help NASA calibrate the measurements from CloudSat, a remote-sensing satellite. Students record the type of clouds and ... > more -
Are Bioluminescent Bacteria Behind Milky Seas Legend?
For centuries, sailors in the Indian Ocean have told stories of seas glowing with a dim, white light at night. Satellite images have now confirmed the appearance of what seem to be bioluminescent ... > more -
Soil Chemists Plant Ferns to Soak Up Backyard Poisons
Planting ferns can be a cheaper, greener way to soak up poisons such as arsenic from the soil. Ferns absorb arsenic through their roots and store it in their leaves, which can then be cut off. ... > more
