Bringing Sunlight Inside
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

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

Turning Trash Into Power
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

Flying and Radiation Risk
At the high altitudes and
latitudes commercial
airlines fly, crews are
subjected to
higher-than-normal radiation
levels from the sun and
cosmic rays. Physicist

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 -
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 -
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 -
Space Physicists and Atmospheric Scientists Can Now Predict Disruptions Caused by the Sun's Coronal Mass Ejections
Solar activity can wreak havoc in communications systems -- particularly during coronal mass ejections, when plumes of electrically charged particles hit earth's atmosphere. Scientists can now track ... > 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 -
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 -
Engineers Design Nails To Better Resist Natural Disasters
Geometry and mathematical calculations were used to design a next-generation nail for building homes that are twice as resistant to high winds and nearly 50 percent more resistant to earthquake ... > more -
Electrical Engineers Create Money-saving Light System
A photosensor paired with a dimming ballast controls fluorescent lighting and adjusts lights all over the user's home. A microcontroller automatically calibrates amounts of daylight and adjusts ... > 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 -
Atmospheric Scientists Map Pollution Decrease
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 ... > more
