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 -

RFID-Based Recycling Technology Makes Philadelphia Greener
Electrical engineers have developed a system that identifies a recycling bin by its household, using Radio Frequency IDentification (RFID) chips embedded in the bins. Bins are scanned and weighed ... > more -
Physical Chemists Devise Quick Spectrometry-Based Mercury Test
Physical chemists have created a new, cheap test to detect mercury, an element known to harm the brain, kidneys, heart, lungs and immune system. A gold nanorod absorbs mercury from a sample and, then ... > more -
Acoustical Oceanographers Record Noises in the Deep
Manmade and natural sounds, from boat engines to rainfall, sound different below the sea surface. To study their impact of noise on marine life, scientists are submerging devices called Passive ... > more -
Cool Pacific Waters May Not Affect Upcoming Hurricane Season
Like their more dramatic cousins El Niños, La Niñas -- the periodic cooling of ocean waters -- can have a dramatic impact on hurricanes, meteorologists say. The current La Niña, ... > more -
Physicists Show "Antigravity" Mystery Spots Are Optical Illusions
At several hilly locations around the U.S., know as "gravity hills," objects such as cars left on neutral supposedly roll uphill, driven by unknown forces and against the force of gravity. Physicists ... > 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 -
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 -
Meteorologists, Atmospheric Scientists Perfect Next-Generation Weather Simulation
Three severe hurricanes hit the U.S. in 2005. Weather forecasters now hope to reduce the loss of lives caused by hurricanes with better computer modeling. With more precise predictions of a storm's ... > more -
Meteorologists, Wind Engineers Standardize Fujita Scale
The Fujita Scale rates tornadoes based on the damage inflicted upon buildings, so accurate rating requires knowing how resistant buildings were in the first place. Starting February 2007, the ... > more
